What is the study ofthe physiochemical properties of drugs and how they influence the body called?

A. Pharmacokinetics

B. Pharmacotherapeutics

C. Pharmacodynamics

D. Pharmacology

C. In simpler terms,pharmacodynamics is the study of what drugs do to the body.

Pharmacokineticsinvolves the study of

A. physiologic interactions of drugs.

B. distribution rates among various bodycompartments.

C. interactions between various drugs.

D. adverse reactions to medications.

B. Pharmacokineticsinvolves the study of how the drug moves through the body, includingabsorption, distribution, metabolism, and excretion.

A drug given by whichroute is altered by the first-pass effect?

A. Sublingual

B. Subcutaneous

C. Oral

D. Intravenous

C. Medications absorbedin the stomach and small intestine travel through the portal system and aremetabolized by the liver before they reach the general circulation.

The nurse should checka medication how many times before administration of a medication under the“right drug” part of the Six Rights?

A. One time

B. Three times

C. Five times

D. Depends on the drug being administered

B. The nurse should checkthe medication three times and confirm each time that the medication is theright drug before to administration of the medication.

To achieve the mostrapid onset of action, the health care provider will prescribe the medicationto be administered by which route?A. Subcutaneously

B. Intravenously

C. Intramuscularly

D. Intrathecally

B. When a drug isadministered intravenously, it does not need to be absorbed because it isplaced directly into general circulation.

Patients with renalfailure would most likely have problems with drug

A. excretion.

B. absorption.

C. metabolism.

D. distribution.

A. The kidneys areresponsible for the majority of drug excretion.

When a patient asksthe nurse why a lower dose of intravenous pain medication is being given thanthe previous oral dose, what knowledge will the nurse draw on to respond to thepatient?

A. Medications given intravenously are notaffected by the first-pass effect.

B. Medications given orally bypass theportal circulatory system.

C. A large percentage of an intravenouslyadministered drug is metabolized into inactive metabolites in the liver.

D. Drugs administered intravenously enterthe portal system prior to systemic distribution.

A. When drugs with a highfirst-pass effect are administered orally, a large amount of drug may bemetabolized before it reaches the systemic circulation. The same drug givenintravenously will bypass the liver. This prevents the first-pass effect fromtaking place, and therefore more of the drug reaches the circulation.Parenteral doses of drugs with a high first-pass effect are much smaller thanoral doses, yet they produce the same pharmacologic response.

Knowing that thealbumin in neonates and infants has a lower binding capacity for medications,the nurse can expect the prescriber to perform which action to minimize therisk of toxicity?

A. Decrease the amount of drug given

B. Increase the amount of drug given

C. Shorten the time interval between doses D. Administer the medication intravenously

A. A lower bindingcapacity leaves more drug available for action; thus a lower dose would be requiredto prevent toxicity.

A. Drug metabolism is faster.

B. Drug half-life is lengthened.

C. Drug elimination is faster.

D. Protein binding is more efficient.

B. Drug half-life isextended secondary to diminished liver and renal function in the elderly.

Which actions will thenurse perform to ensure the medication dose for a pediatric patient iscorrect? (Select all that apply.)

A. Use the patient’s weight in pounds.

B. Use a current drug reference to determineusual dosage per 24 hours.

C. Determine the dose parameters by multiplyingthe weight by the minimum and maximum daily doses of the drug (the safe range).

D. Determine the total amount of the drug toadminister per dose and per day.

E. Compare the drug dosage prescribed with thecalculated safe range.

F. If the drug dosage prescribed varies fromrecommended reference range, notify the provider.

B., C., D., E., F. Thepatient’s weight needs to be in kilograms, not pounds. All otherinformation listed is correct and must be followed by the nurse to ensure thecorrect pediatric dosage.

Which statement bestreflects the nurse’s understanding of cultural influences on drug therapy andother health practices?

A. Administration of some drugs may elicitvaried responses in specific racial-ethnic groups. B. Regardless of one’s culturalbackground, it is crucial to always adhere to recommended medical practices.

C. Most cultures are fairly standard inreference to the use of medications during illness.

D. Dietary habits and practices can be oflittle value to the care of an ill adult.

A. Knowledge about drugsthat may elicit varied responses in specific racial or ethnic groups mustremain current. For example, genetic changes in certain CYP enzymes affect therate of drug metabolism and thus affect drug levels and dosage amounts.Cultural practices vary among individuals and should be implemented as an integralpart of holistic nursing care. Dietary habits and practices can affect thepharmacokinetics of medications and are thus an important aspect of thepatient’s history.

The nurse is assessinga patient’s culture and race on admission to the hospital. Which concept is importantfor the nurse to understand regarding drug therapy as it relates to differentraces of individuals?

A. Polypharmacy

B. Polymorphism

C. Pharmacokinetics

D. Pharmacodynamics

B. Drug polymorphismrefers to the effect of a patient’s age, gender, size, body composition, andother characteristics on the pharmacokinetics of specific drugs. The race of anindividual may influence drug therapy decisions for the individual. Polypharmacy is the use of many different drugsconcurrently in treating a patient, who often has several health problems. Pharmacokinetics is the study of what happens to adrug from the time it is put into the body until the parent drug and allmetabolites have left the body. Pharmacodynamics isthe study of what the drug does to the body.

The emergencydepartment nurse is documenting the history of a patient of Asian culture. Thepatient states that she does not take any medications, but the nurse notes abottle of capsules in the patient’s purse. What information will the nurse collectnext?

A. Vital signs

B. Primary care provider name

C. Use of herbs or over-the-countermedications

D. Insurance information

C. The nurse will ask thepatient if she takes any herbs or other non-prescribed medications. The patientis of Asian culture and may use herbal remedies that she does not considermedications.

When planninginterventions aimed at reducing medication errors, the nurse recognizes that

A. only 10% of all preventable adversedrug reactions (ADRs) begin at the medication ordering (prescribing) stage.

B. disciplinary action is necessary toincrease the nurse’s vigilance in preventing medication errors.

C. the majority of medication errorsresult from weaknesses within the system rather than individualshortcomings.

D. the use of trailing zeros (i.e., 1.0mg) and omission of leading zeros (i.e., .25 mg) reduces transcription errors.

C. It is widelyrecognized that the majority of medication errors result from weaknesses withinthe “system” structure of health care organizations, resulting less often fromindividual shortcomings. Vindictive disciplinary action or “finger pointing” isnow generally recognized as being counterproductive in the prevention ofmedication errors. Studies have shown that one half of all preventable ADRsbegin at the medication ordering (prescribing) stage. The use of leading zerosand omission of trailing zeros will help prevent transcription errors.

When admitting an elderlypatient to an acute care setting, which nursing strategy is most appropriate toprevent medication errors?

A. Call the primary care physician toverify current medications.

B. Ask the patient’s family to verifymedications the patient was taking at home.

C. Ask the patient to provide you with awritten list of all medications being taken at home.

D. Ask the patient and/or family to bringin all medications the patient was taking at home.

D. The USP recommends theuse of “brown bagging” sessions of medications to identify drugs that patientsare taking. Patients, family, and/or the primary care physician may not alwaysaccurately report all medications a patient is using. Actual examination of themedications and containers provides the most accurate assessment of currentmedications and allows for appropriate medication reconciliation.

In which step of themedication process can a medication error occur? (Select all that apply.)A. Procurement

B. Prescribing

C. Transcribing

D. Verification

E. Administration

A., B., C., E. Medicationerrors can occur at any point in the medication process: procuring,prescribing, transcribing, dispensing, and administration. Verification is astep in the medication reconciliation process.

The nurse knows thatthe medication reconciliation process involves which three steps? (Select all that apply.)

A. Reporting

B. Reconciliation

C. Verification

D. Administration

E. Clarification

B., C., E. Thethree steps of the medication reconciliation process are verification,clarification, and reconciliation.

When administering a medication subcutaneously, the nurse will

A. use a 1- to 1½-inch, 25-gauge needle.

B. insert the needle at a 45- or 90-degree angle,depending on patient size, to penetrate subcutaneous tissue.

C. aspirate with heparin and insulin injections. D. use the landmark between the greater trochanter andsuperior iliac crest for the vastus lateralis site.

B. The proper technique for subcutaneous injections involves theuse of a 1/2- to 5/8-inch needle, 25-gauge, at a 45- or 90-degree angle ofinsertion dependent on patient size, and aspiration is not done withanticoagulants and insulin. The landmark for the vastus lateralis is onehandbreadth below the greater trochanter and above the knee on the outer aspectof the thigh.

The nurse will use a Z-track technique when giving anintramuscular injection in which situation?

A. When there is insufficient muscle mass in thelandmarked area

B. When massaging the area after medicationadministration is contraindicated

C. With medications that are known to be irritating,painful, and/or staining to tissues

D. With any injection that is given into the ventroglutealmuscle

C. The Z-track method prevents medication from leaking intosubcutaneous tissues where it can be irritating and/or painful. This methodshould be used with medications that are particularly irritating to the tissue.Some institutional policies require the use of the Z-track method with allintramuscular injections.

Which are the appropriate landmarks for an intramuscularinjection into the dorsogluteal region?

A. A “V” formation between the anterior superior iliacspine and the greater trochanter

B. A handbreadth below the greater trochanter and thesacroiliac joint

C. The dorsogluteal region is no longer recommended forinjection; select a different site.

D. Below the iliac spine and between the greatertrochanter and the iliac crest

C. The dorsogluteal injection site is no longer recommended forinjections because of the close proximity to the sciatic nerve and major bloodvessels. Injury to the sciatic nerve from an injection may cause partialparalysis of the leg. The dorsogluteal site is not to be used for intramuscularinjections.

When administering a sublingual medication, which action willthe nurse perform?

A. Ask the patient to chew the medication so that it willabsorb faster.

B. Wear gloves to place the tablet under the patient’stongue.

C. Instruct the patient to drink room temperature waterto enhance dissolution.

D. Have the patient swallow several times while thetablet dissolves.

C. pain relief is best obtained by administering analgesics around the clock.

D. patients should request analgesics when the pain level reaches a “6” on a scale of 1 to 10.

C. When pain is present for morethan 12 hours a day, analgesic dosages are best administered around the clockand not “as needed,” but dosages should always be within the dosage guidelinesfor each drug used. The around-the-clock (or “scheduled”) dosing allows steadystates of the medication and prevents drug dosage “troughs” and escalation ofpain.

Most nonsteroidal antiinflammatory drugs (NSAIDs) work by

A. enhancing pain perception.

B. inhibiting prostaglandin production.

C. increasing blood flow to painful areas.

D. increasing the supply of naturalendorphins

B. Prostaglandins are produced inresponse to activation of the arachidonic pathway. NSAIDs work by blockingcyclooxygenase, the enzyme responsible for conversion of arachidonic acid intoprostaglandins. Decreasing the synthesis of prostaglandins results in decreasedpain and inflammation.

When teaching a patient about potential side effects ofNSAID therapy, the nurse will teach the patient to promptly report whicheffect?

A. Mild indigestion

B. Black tarry stools

C. Nonproductive cough

D. Nausea

B. A major side effect of NSAIDtherapy is gastrointestinal (GI) distress with potential GI bleeding. Blacktarry stools are indicative of a GI bleed.

A. have a longer duration of action.

B. are less likely to cause hepatic toxicity.

C. do not decrease the cytoprotective lining of the stomach.

D. have a more rapid onset of action.

C. By not inhibiting the COX-1enzyme, production of the protective mucus by parietal cells in the GI tract ismaintained, thus decreasing the risks of GI side effects.

A. tetracycline

B. cefazolin sodium (Ancef)

C. gentamicin (Garamycin)

D. erythromycin

B. Patients who are allergic topenicillins have a fourfold to sixfold increased risk of allergy to otherbeta-lactam antibiotics. The incidence of cross-reactivity betweencephalosporins and penicillins is reported to be between 1% and 4%.

The nurse will question the use of a floroquinoloneantibiotic in a patient already prescribed which medication?

A. amiodarone

B. metoprolol

C. furosemide

D. omeprazole

A. Dangerous cardiac dysrhythmiasare more likely to occur when quinolones are taken by patients receiving classIA and class III antiarrhythmic drugs such as disopyramide and amiodarone. Forthis reason, such drug combinations should be avoided.

Quinolones are a class of antibiotics known for severalsignificant complications. Which are possible adverse effects with these drugs?(Selectall that apply.)

A. Abnormal cartilage development in children

B. Prolongation of the QT interval

C. Tendon rupture

A., B., C. Quinolones are notused in prepubescent children due to the risk of cartilage development issues.Quinolones may also cause a cardiac effect that involves prolongation of the QTinterval on the electrocardiogram. The use of these medications can result intendonitis or rupture tendons in adults. Nephrotoxicity and ototoxicity are notassociated with quinolones.

When reviewing a patient’s medication regimen beforedischarge, the patient asks why he is taking pyridoxine when he is alreadytaking isoniazid (INH) to treat tuberculosis. What is the nurse’s bestresponse?

A. “Pyridoxine is another antitubercular drugthat will work synergistically with the isoniazid.”

B. “You really should not be on that drug. Iwill check with the doctor.”

C. “Pyridoxine will help prevent numbness andtingling that can occur secondary to the isoniazid.”

D. “Multidrug therapy is necessary to preventthe occurrence of resistant bacteria.”

C. INH can cause neurotoxicity.Pyridoxine, vitamin B6, is the drug of choice to prevent this adverse reaction.It is not an antiinfective drug and thus will not work to destroy themycobacterium or prevent drug resistance.

What information must be provided to a patient receivingrifampin?

A. A nonharmful side effect of the drug is red-orange discoloration of urine, sweat, and tears.

B. Oral contraception is the preferred method of birth control when using rifampin.

C. Peripheral neuropathy is an expected side effect, and the patient should report any numbness or tingling of the extremities.

D. The patient will only need to take this medication for the prescribed 14-day period.

A. Red-orange discoloration of bodyfluids is a common side effect of rifampin, but it is not harmful. Rifampindoes not cause peripheral neuropathies (INH does), but it does interfere withthe effectiveness of oral contraceptives. All antitubercular drugs need to betaken long term in order to eradicate the slow-growing mycobacterium lying deepwithin the tissues.

A. these drugs will only need to be taken for 7 to 10 days.

B. INH may decrease serum glucose in susceptible people.

C. oral contraceptives become ineffective when given with rifampin.

D. tanning beds may be used to counteract the pale skin tone caused by these medications.

C. Women taking oral contraceptiveswho are prescribed rifampin must be switched to another form of birth controlbecause oral contraceptives become ineffective when given with rifampin. Thesemedications must be taken long term because mycobacterium is slow growing. Theycan cause photosensitivity, necessitating the use of sunscreen, not tanningbeds. Finally, INH may increase, not decrease, serum glucose levels.

When assessing for adverse reactions to Rifamate(combination isoniazid and rifampin), the nurse would monitor which laboratoryvalues? (Select all that apply.)

A. Liver function tests


C. Sputum cultures

D. Uric acid levels

A. opioid abuse.

B. alcohol abuse.

C. barbiturate abuse.

D. amphetamine abuse.

A. Naltrexone (ReVia), an opioidantagonist, is used to treat opioid abuse or dependence. Naltrexone works byblocking the opioid receptors so that use of opioid drugs does not produceeuphoria. When euphoria is eliminated, the reinforcing effect of the drug islost.

What is the goal of pharmacologic therapy in treatingParkinson’s disease?

A. To increase the amount of acetylcholine at thepresynaptic neurons

B. To decrease the amount of dopamine available in thesubstantia nigra

C. To balance cholinergic and dopaminergic activity inthe brain

D. To block dopamine receptors in both presynaptic andpostsynaptic neurons

C. Parkinson’s disease results froma decrease in dopaminergic (inhibitory) activity, leaving an imbalance with toomuch cholinergic (excitatory) activity. By increasing dopamine, theneurotransmitter activity becomes more balanced and symptoms become controlled.

The mother of a child with attention deficit hyperactivitydisorder (ADHD) who has been prescribed methylphenidate (Ritalin) expressesconcern regarding the use of a controlled substance to treat her child and asksif there are any other options. The nurse’s response is based on the knowledgethat an option for treatment for ADHD might include which non-controlledcentral nervous system (CNS) stimulant?

A. atomoxetine (Strattera)

B. dextroamphetamine sulfate (Dexedrine) C. methylphenidate (Concerta)

D. amphetamine aspartate (Adderall)

A. CNS stimulants decrease the production of excitatoryneurotransmitters.

B. CNS stimulants increase release of and block reuptakeof neurotransmitters.

C. CNS stimulants block the activity of inhibitoryneurons.

D. CNS stimulants enhance the effects ofphosphodiesterase and subsequent breakdown of cyclic adenosine monophosphate(cAMP).

B. CNS stimulation occurs when theamount of neurotransmitters being released and the duration of action ofexcitatory neurotransmitters are increased.

When assessing a patient for adverse effects related tomorphine sulfate, which effects would the nurse expect to find? (Select allthat apply.)A. Decreased peristalsis

B. Diarrhea

C. Delayed gastric emptying

D. Urinaryretention

A., C., D. Morphine sulfate causes a decrease in gastrointestinal motility (delayed gastric emptying and decreased peristalsis). This leads to constipation, not diarrhea. Morphine can also cause urinary retention.

When assessing for cardiovascular effects of an adrenergic(sympathomimetic) drug, the nurse understands that these drugs produce

A. a positive inotropic, positive chronotropic, and positive dromotropic effect.

B. a positive inotropic, negative chronotropic, and negative dromotropic effect.

C. a negative inotropic, positive chronotropic, and positive dromotropic effect.

D. a negative inotropic, negative chronotropic, and negative dromotropic effect.

A. Adrenergic stimulation of thebeta1-adrenergic receptors on the myocardium and in the conductionsystem of the heart results in an increased heart rate (positive chronotropiceffect), increased contractility (positive inotropic effect), and increasedconductivity (positive dromotropic effect).

When assessing for cardiovascular effects of a beta blocker,the nurse understands that these drugs produce

A. a positive inotropic, positive chronotropic, and positive dromotropic effect.

B. a positive inotropic, negative chronotropic, and negative dromotropic effect.

C. a negative inotropic, positive chronotropic, and positive dromotropic effect.

D. a negative inotropic, negative chronotropic, and negative dromotropic effect.

A patient using Afrin nasal spray complains of worseningcold symptoms and tells the nurse, “I don’t understand why this is not working.I am using it almost every 3 hours!” The nurse’s response is based on knowledgethat

A. Afrin nasal spray is not an effective nasal decongestant.

B. the medication needs to be used every 30 minutes for maximum effectiveness.

C. the patient is suffering from rebound congestion related to excessive use of the Afrin nasal spray.

D. adrenergic decongestants should only be used prophylactically, not to treat acute congestion. Incorrect

C. Afrin nasal spray is asympathomimetic drug with both alpha- and beta-adrenergic effects. Thealpha-adrenergic activity is responsible for causing vasoconstriction in thenasal mucosa. However, excessive use of nasal decongestants can lead to greatercongestion because of a rebound phenomenon that occurs when use of the productis stopped.

Cholinergic (parasympathomimetic) drugs have which therapeutic effect?

A. Urinary retention

B. Increased gastrointestinal motility

C. Mydriasis

D. Vasoconstriction

B. Cholinergic effects mimic theparasympathetic nervous system (rest and digest) as opposed to the sympatheticnervous system (fight or flight). Increasing gastrointestinal (GI) motilityhelps the body digest. Urinary retention, mydriasis, and vasoconstriction aresympathetic nervous system responses.

During postoperative teaching, the nurse explains that thepatient is receiving bethanechol (Urecholine) to treat

A. postoperative hypotension.

B. urinary atony.

C. respiratory atelectasis.

D. postoperative ischemic colitis.

B. Bethanechol is a direct-actingcholinergic agonist that stimulates the cholinergic receptors on the smoothmuscle of the bladder, leading to bladder contraction and emptying.

The nurse administering donepezil (Aricept) to a patientunderstands that the expected therapeutic action of this drug is to

A. relieve anxiety and restless behavior of the patient.

B. increase levels of acetylcholine in the brain by blocking its breakdown.

C. block the effects of acetylcholine at the presynaptic neurons.

D. help control associated urinary incontinence.

B. Donepezil is used to treatAlzheimer’s disease, a disorder of decreased acetylcholine levels in the brain.Donepezil is an indirect-acting anticholinesterase drug.

When providing teaching to a patient diagnosed withmyasthenia gravis, which instruction regarding the administration ofphysostigmine (Antilirium) is most appropriate?

A. Increase fluid and fiber in the diet to prevent constipation. Incorrect

B. Take the medication 30 minutes before meals.

C. If a dose is missed, double the next dose to prevent withdrawal.

D. Common side effects include tachycardia and hypertension.

B. Drugs used for myasthenia gravisshould be given about 30 minutes before meals to allow for onset of action andtherapeutic effects (e.g., decreased dysphagia). Constipation, tachycardia, andhypertension are not effects of cholinergic medications. A missed dose shouldnever be doubled.

The provider has ordered donepezil (Aricept) for thepatient, and the patient states “I have no idea why I take this medication.”What is the most common diagnosis associated with the administration ofdonepezil (Aricept)?

A. Parkinson’s disease

B Bladder retention

C. Alzheimer’s disease

D. Urinary retention

C. Donepezil (Aricept) is acholinesterase inhibitor drug that works centrally in the brain to increaselevels of acetylcholine by inhibiting acetylcholinesterase. It is used in thetreatment of mild to moderate Alzheimer’s disease.

The nurse is providing education to a patient on the primaryuses of cholinergic drugs. Which uses would the nurse include in theteaching? (Select all that apply.)

A. To stimulate peristalsis

B. To elevate heart rate

C. To decrease intraocular pressure

D. To stimulate bladder emptying

A. the risk of constipation is decreased.

B. lower doses of medication are cost-effective. C. different vomiting pathways are blocked.

D. increased sedation is achieved by higher doses of medication.

C. Combining antiemetic drugs fromvarious categories allows the blocking of the vomiting center and chemoreceptortrigger zone through different pathways, thus enhancing the antiemetic effect.

A patient receiving an anticholinergic drug to treat nauseaand vomiting should be taught to expect which side effect?

A. Diarrhea

B. Lacrimation

C. Dry mouth

D. Bradycardia

C. Anticholinergic drugs block theparasympathetic nervous system, which causes the body to “rest and digest.”Blocking of these effects leads to constipation, urinary retention, anddecreased secretions (dry mouth).

When planning administration of antiemetic medications to apatient, the nurse is aware that combination therapy is preferred because

A. the risk of constipation is decreased.

B. lower doses of medication are cost-effective. C. different vomiting pathways are blocked.

A. Coronary artery disease

B. Chronic obstructive pulmonary disease(COPD)

C. Hyperkalemia

D. Premature labor

A. Nonselectiveadrenergic agonist bronchodilators stimulate beta1 receptorsin the heart and beta2 receptors in the lungs.Stimulation of beta1receptors can increase heartrate and contractility, increasing oxygen demand. This increased oxygen demandmay lead to angina or myocardial ischemia in patients with coronary arterydisease.

Patient teachingregarding the use of antileukotriene drugs such as zafirlukast (Accolate) wouldinclude which statement?

A. “Take the medication as soon as youbegin wheezing.”

B. “It will take about 3 weeks before younotice a therapeutic effect.”

C. “This medication works by preventingthe inflammation that causes your asthma attack.”

D. “Increase fiber and fluid in your dietto prevent the common side effect of constipation.”

C. Antileukotriene drugsblock the inflammatory response of leukotrienes and thus the trigger for asthmaattacks. Response to these drugs is usually noticed within 1 week. They are notused to treat an acute asthma attack. Diarrhea, not constipation, is an adverseeffect of the antileukotriene drugs.

What is the role ofcorticosteroids in the treatment of acute respiratory disorders?

A. They stimulate the immune system.

B. They directly dilate the bronchi.

C. They increase gas exchange in thealveoli. D. They decrease inflammation.

D. Corticosteroidssuppress the immune system. They do not directly affect bronchodilation butrather prevent bronchoconstriction as a response to inflammation.

Which statement by apatient best demonstrates an understanding of the teaching on flunisolide (AeroBid)?

A. “I will take two puffs to treat anacute asthma attack.”

B. “I will rinse my mouth with water aftereach use.”

C. “I will immediately stop taking my oralprednisone as soon as I start using the AeroBid.” D. “I will not use my albuterol inhalerwhile I am taking AeroBid.”

B. Flunisolide is aninhaled corticosteroid. Rinsing the mouth will help prevent oral candidalinfections. It is not used to treat an acute asthma attack and should be takenwith the patient’s bronchodilator medications. If the patient is taking oralprednisone, it needs to be tapered off to prevent acute adrenal crisis sinceflunisolide is minimally absorbed systemically.

Mast cell stabilizersare most effective in treating bronchoconstriction associated with whichcondition?

A. Emphysema

B. Exposure to cold

C. Allergens

D. Infection

C. Mast cell stabilizerswork by preventing the release of chemical mediators that cause bronchospasmand are most effective in preventing asthma caused by extrinsic factors such asallergens or exercise.

What statement by thepatient, who is using the anticholinergic inhaler ipratropium bromide(Atrovent), indicates to the nurse that teaching has been successful?

A. “I will increase my intake ofcaffeine.”

B. “I may gain weight as a result of takingthis medication.”

C. “Nausea and vomiting are common adverseeffects of this medication, so I will always take it with meals.”

D. “This inhaler is not to be used aloneto treat an acute asthma attack.”

D. Although ipratropiumworks to prevent bronchoconstriction and thus secondarily leads tobronchodilation, a direct-acting bronchodilator is needed to treat an acuteasthma attack.

The physician ordersipratropium bromide (Atrovent), albuterol (Proventil), and beclomethasone(Beclovent) inhalers for your patient. Put the drugs in the correct order inwhich they will be administered, using the choices A through C listed below.

A., B., C. Albuterol first, then ipratropium bromide, and then beclomethasone

To prevent oral candidiasis, it is most important for the nurseto teach a patient using a steroid inhaler to perform which action?

A. Rinse the mouth after each use.

B. Minimize use of an inhaler to everyother day.

C. Swish and swallow with mycostatin aftereach use.

D. Report any gingival irritation to thehealth care provider.

A. It is most important to teach patients to rinse their mouth aftereach use of a steroid inhaler to prevent the occurrence of oral candidiasis, afungal infection. Mycostatin is not routinely used to prevent this infectionunless the patient is immunocompromised. Reporting irritation once it hasoccurred does not prevent the infection. Minimizing the use of the inhaler toevery other day negates its therapeutic effect.

What side effect of angiotensin-converting enzyme (ACE)inhibitors most often results in the provider changing the treatment plan to anangiotensin receptor blocker?

A. Orthostatic hypotension

B. Dry, nonproductive cough

C. Fatigue

D. Hypokalemia

B. ACE inhibitors prevent thebreakdown of bradykinin, frequently causing a nonproductive cough. Angiotensinreceptor blockers do not block this breakdown, thus minimizing this annoyingside effect.

Which medication would the nurse question if prescribedconcurrently with ACE inhibitors? A. furosemide (Lasix)

B. morphine

C. Colace

D. potassium

D. ACE inhibitors block theconversion of angiotensin I to angiotensin II, thus also blocking the stimulusfor aldosterone production. Aldosterone is responsible for potassiumexcretion—decreased aldosterone can result in increased serum potassium.

The nurse would plan to administer which calcium channelblocker to a patient with cerebral artery spasms following a subarachnoidhemorrhage?

A. amlodipine (Norvasc)

B. diltiazem (Cardizem)

C. nimodipine (Nimotop)

D. verapamil (Calan)

C. Nimodipine crosses theblood-brain barrier and has a greater effect on the cerebral arteries than onother arteries in the body; thus, it is indicated for the treatment of cerebralartery spasm following subarachnoid hemorrhage.

The nurse is conducting a community education program. Whenexplaining different medication regimens to treat hypertension, it would beaccurate to state that African Americans probably respond best to whichcombination of medications?

A. ACE inhibitors and diuretics

B. Diuretics and calcium channel blockers

C. Diuretics and beta blockers

D. ACE inhibitors and beta blockers

B. Research has demonstrated thatAfrican Americans do not typically respond therapeutically to beta blockers orACE inhibitors. They respond better to diuretics and calcium channel blockers.

ACE inhibitors and angiotensin receptor blockers both workto decrease blood pressure by

A. preventing the formation of angiotensin II.

B. enhancing sodium and water resorption.

C. increasing the breakdown of bradykinin.

D. preventing aldosterone secretion.

D. ACE inhibitors block theformation of angiotensin II, whereas angiotensin receptor blockers allow theformation of angiotensin II but block its effect at the receptors. Without thereceptors stimulated (because of either drug), aldosterone is not produced,diminishing the reabsorption of sodium and water.

Which is a priority nursing diagnosis for a patient takingan antihypertensive medication?

A. Ineffective cerebral tissue perfusion related to disease process and/or medication

B. Deficient knowledge related to medication regimen

C. Fatigue related to side effects of medication D. Risk for injury to mucous membranes related to medication side effects

A. Ineffective cerebral tissueperfusion is always a priority over fatigue, risk for injury, and/or knowledgedeficit. Patients taking antihypertensive medication are also at risk forineffective renal and cardiac perfusion.

B. “Apply the patch to the same site each day to maintain consistent drug absorption.”

C. “If you get a headache, remove the patch for 4 hours and then reapply.”

D. “If you get chest pain, apply a second patch right next to the first patch.”

A. A nitroglycerin patch should beapplied to a nonhairy, nonirritated area for the best and most consistentabsorption rates. Sites should be rotated to prevent skin irritation, and thedrug should be continued if headache occurs because tolerance will develop.Sublingual nitroglycerin should be used to treat chest pain.

Which statement by the patient demonstrates a need forfurther education regarding nitroglycerin?

A. “If I get a headache, I should keep taking my nitroglycerin and use Tylenol for pain relief.”

B. “I should keep my nitroglycerin in a cool, dry place.”

C. “I should change positions slowly to avoid getting dizzy from the nitroglycerin’s effect on my blood pressure.”

D. “I can take up to four tablets at 5-minute intervals for chest pain.”

D. Patients are taught to take upto three tablets 5 minutes apart. According to current guidelines, if the chestpain or discomfort is not relieved in 5 minutes, after one dose, the patient(or family member) must call 911 immediately.

In order to prevent the development of tolerance, the nurseinstructs the patient to perform which action?

A. Apply the nitroglycerin patch every other day. B. Switch to sublingual nitroglycerin when the patient’s systolic blood pressure elevates to >140 mm Hg.

C. Apply the nitroglycerin patch for 16 hours each and remove for 8 hours at night.

D. Use the nitroglycerin patch for acute episodes of angina only.

C. Tolerance can be prevented bymaintaining an 8-hour nitrate-free period each day

A. “You can protect it from heat by placing the bottle in an ice chest.”

B. “It’s best to keep it in its original container away from heat and light.”

C. “You can put a few tablets in a resealable bag and carry in your pocket.”

D. “It’s best to lock them in the glove compartment of your car to keep them away from heat and light.”

B. Although nitroglycerin needs to be kept in a cool, dryplace, it should not be placed in an ice chest where it could freeze. It shouldalso not be locked up and needs to be kept away from light, not in a clearplastic bag.

Patient teaching regarding sublingual nitroglycerin shouldinclude which statement?

A. “You can take up to five doses every 3 minutes for chest pain.”

B. “Chew the tablet for the quickest effect.”

C. “Keep the tablets locked in a safe place until you need them.”

D. “Sit or lie down after you take a nitroglycerin tablet to prevent dizziness.”

D. Nitroglycerin is a vasodilatorand can cause orthostatic hypotension, resulting in dizziness. It should bekept in a readily accessible location for immediate use should chest painoccur. Three tablets may be taken 5 minutes apart. It should be placed underthe tongue and allowed to dissolve.

Which statement indicates that the patient understandsdischarge teaching about nitroglycerin?

A. “I will need to refill my prescription once a year in order to maintain potency.”
