bones, cerebral cortex,
liver, kidney
may become dormant or walled

treated with antibiotics
<produces inflammatory and
necrotic lesions in the
only 5-10% infected will
develop active TB...the
risk of transmission is
reduced after about 2-3
weeks of treatment
incidence is steadily
increasing all over
(HIV patients have brought
this number up; anyone
in close contact can carry
it; foreign immigrants)
<What are some of the manifestations of someone that has tuberculosis?
weight loss
<To diagnose TB, what test is done?

0.1 mL...and what does PPD stand for?

72 hours
sputum smear for acid fast bacilli...
sputum cultures for Mycobacterium tuberculosis...
Mantoux test is the most preferred test for diagnosing much PPD solution is given for a TB test?

purified protein's given intradermally in the does one know if it's a positive test for somebody that's not immunocompromised?

5 mL...when is the best time to get an accurate test?
<Interventions include a combination of drug therapy...what are the primary drugs?
<isoniazid (INH)
<What two drugs are used throughout TB therapy?
isoniazid (INH)
<What are nursing implications of isoniazid (INH)?
<increased toxicity if taking
phenytoin, carbamazepine,
primidone, warfarin
take on empty stomach
avoid antacids
monitor for signs of
hepatitis and neurotoxic
<What are some signs of hepatotoxic effects when taking isoniazid (INH)?
liver pain
enlarged liver
liver enzymes will be

<peripheral neuritis which is paresthesias of the hand and feet...vitamin B6 helps
<What are the nursing implications of rifampin?
secretions and urine will be orange and drug will permanently discolor soft contact lenses...
hepatotoxic effects
decreased effectiveness or oral contraceptives..
hematologic disorders

<Ethambutol (EMB) nursing implications are?
<obtain baseline visual acuity and color discrimination (esp green) it affects rods and cones and their red-green shade color blindness and they should be told to repeat their vision testing every one to two months..can cause retrobulbar neuritis and blindness

repeat vision testing every 1-2 months>
<Streptomycin nursing implications are?
<eighth cranial nerve impairment and that affects hearing and this esp. affects elderly clients that are taking this medication..ototoxicity
<Amikacin nursing implications are?
ensure adequate hydration
monitor renal function
monitor hearing
because of renaltoxicity and ototoxicity>
<Rifapentine (Priftin) nursing implications are?
<doses must be separated by at least 72 hours
observe for hepatotoxic effects
metabolism of other drugs may be faster and cause need for higher dose>

<one reason why birth control pills don't work as well is because these meds cause metabolism of other drugs to be faster and the faster their metabolized, the lower the blood level of these drugs so they have to have higher doses>
<Patient education regarding tuberculosis is?
sputum specimens will be collected every 2 to 4 weeks once drug therapy has begun...once 3 negative cultures are obtained, then they're considered no longer infectious and they can go back to work...

take daily meds at bedtime...helps prevent nausea and reinforce that not taking their drugs as prescribed can lead to a superinfection and drug resistance...even though their tests are negative and they're feeling better, they'll still be on meds for six months or more...they need to continue regimen

need well-balanced diet to promote healing and encourage them to have foods that are rich in iron and protein and vitamin C

these patients are usually very fatigued and weak, so physical stamina is important to address...encourage them that their fatigue and weakness will decrease rapidly as they start medications>

Identify all contacts that they've had...they need to be tested...those that are high at risk may receive prophylactic therapy and they usually use "INA (INH)? " prophylactically
for those that have been exposed...

most patients can be treated at home..airborne precautions aren't necessary if they're treated at home because they've been around those people before they were diagnosed with they've already been exposed...instruct them to cover their mouths and nose when they cough or sneeze and put it into a plastic bag before they dispose of it...they need to wear a mask whenevery they're out in public until cultures are the health care setting, they need to be in an isolation room that provides at least 6 air exchanges and preferably exchanges air to outside of the hospital...nurse should wear an N95 or higher respirator and gown and gloves....
