What size syringe should be used for a CVAD blood draw? Why?
How much saline should be flushed before a blood draw (CVAD)? Why?
Flush with 5-10mL saline BEFORE blood draw (except for blood cultures). This will assure catheter is patent first.
After flushing with saline prior to a blood draw, what should be done with the saline in the catheter?
Need to withdraw the saline that’s in the catheter OUT before drawing the blood sample (so, aspirate 5mL and DISCARD it in the Sharps Container.
When feeding a patient in bed, what position should the bed be in before and after eating?
Assure that the patient’s head of bed (HOB) is elevated 45
degrees during and AFTER feeding (for at least 30 minutes)”
Why are NGT known as "blind insertion" devices?
You really don’t know where the tip is until you confirm it. If the tube is inserted for enteral feedings, the physician MUST order an x-ray to check placement AND you must get the results that it is indeed in the stomach BEFORE you start ANY enteral feedings.
Can vaseline ever be used to insert an NGT?
No, never -- only specific lubricant like surgilube.
When inserting an NGT, what should you be aiming for?
What is the frequency of irrigation for a feeding tube?
Usually every 4 to 12 hours (each hospital may vary)
How often should an irrigation set be replaced for a feeding tube?
The irrigation set should be replaced every 24 hours. If you’re flushing an NGT and the set does not have a date/time……discard and get a new one.
While on TPN, the goal is for the patient to gain __ pounds per week.
1 - 3 lbs
True or false - TPN is ALWAYS administered via an infusion pump.
If a CVAD is being used for parenteral nutrition administration, can it also be used for blood draws and medication administration?
No - when a CVAD is used for parenteral nutrition administration, it should be
“dedicated” solely for that purpose. It should not be used for blood drawing
or administration of any IV fluid or medications. Why? Every time you
interrupt a closed sterile system you risk contamination….and with this type
of solution, with a high dextrose content, infection is a real and serious risk.
What labs should be checked prior to starting lipid infusions?
it is important to check the patient’s triglyceride level BEFORE starting lipid infusions and then 6 hours AFTER to assure the patient is able to metabolize the lipid solution.
What type of tubing is required for lipid infusions? Why?
Because lipid solutions are often prepared in a glass bottle, “vented”
tubing is required. When administering solutions in a bag, the bag
collapses as the fluid is infused. This does not hold true for any solution
in a bottle. As a result, this vented tubing allows for inflow of air into the
bottle which allows the solution to flow into the patient’s IV.

When performing an NGT insertion, how do you gauge the length of tube to be inserted?
Measure the tubing from the tip of the nose to the earlobe to the xiphoid process (sternum base); mark off the length with tape

The LPN/LVN is assisting the RN to prepare for a blood transfusion. Which IV fluid will the LPN/LVN obtain to administer before and after the blood?
1. D5W
2. D5 in half normal saline
3. Half normal saline (0.45% NaCl)
4. Normal Saline (0.9% NaCl)
Answer - Normal saline, or 0.9% sodium chloride, solution is used with transfusion therapy and is established in policies and procedures.
When the nurse suspects a possible transfusion reaction, he or she will first:
1. Notify the physician
2. Monitor the client every 5 minutes or until you determine if a serious or mild reaction is occurring
3. Stop the transfusion. Disconnect the blood and blood tubing and discard them immediately.
4. Stop the transfusion. Change the IV tubing and start a saline infusion at a keep-open rate
Answer - Treat all reactions seriously until proven otherwise. Upon suspicion of a transfusion reaction, stop the transfusion, change the IV tubing and start a saline solution at a keep-open rate. Do not discard the blood container or administration set. These will be returned to the blood bank. Notify the physician.
A client has severe anemia. Which type of transfusion would you expect to be ordered for him?
1. Cryoprecipitate
2. Red Blood Cells
3. Albumin
4. Platelets
Answer - Red blood cells are given to increase hemoglobin levels in severe anemia; platelets and cryoprecipitate are given for coagulation disorders, and albumin is given to increase plasma volume.
A client with congestive heart failure is on continuous IV fluids. He complains of being uncomfortable and having difficulty breathing. To further assess this client the nurse would:
1. Check for mental status changes and a rapid, weak pulse.
2. Listen for crackles in the lungs and look for intake greater than output.
3. Get a tympanic temperature and check the white blood cell count.
4. Check the skin for a rash and listen for wheezes in the lungs.
Answer - For circulatory overload, assess for neck vein engorgement, crackles in the lungs, and changes in intake and output. This complication may be caused by a too-rapid flow rate, an error in fluid requirements, or IV therapy in a client with renal or cardiac conditions.
__ fluids have the same osmolarity as body fluids and are used most often to replace extracellular volume (eg. prolonged vomiting).
__ fluids effectively mimic the body's fluid loss in the absence of an electrolyte imbalance.
__ solutions are those that have an effective osmolarity LESS than that of body fluids.
__ solutions are those that have an effective osmolarity GREATER than that of body fluids and can be used in cases of dehydration.
___ solutions pull fluid into the vascular space by osmosis, resulting in an increased vascular volume that will possibly result in pulmonary edema.
Under no circumstances should a nurse give potassium chloride via ___
IV Push
True or false - fluid and electrolyte imbalances affect vital signs.
Dehydration sometimes produces __ (hypotension/hypertension).
True or false - fluid overload can result in hypotension and a weak pulse.
False - fluid overload can result in hypertension and a bounding pulse.
True or false - As part of IV administration, the saline lock should be flushed with 0.9% sodium chloride solution or after each administration of medication to maintain patency of the IV catheter (according to institution protocol).
Why should IV tubing be kept free of air and air bubbles?
Air bubbles, esp. large ones, can result in and act as emboli.
What are the best veins for IV placement in adults?
Cephalic, basilic, and median cubital veins of the arm
How often should a nurse monitor a patient receiving IV therapy?
Every 1 to 2 hours to assure correct administration of fluid volume
What additional sites can be used for IV therapy for pediatric clients (in addition to the sites used for adults)?
Veins in the scalp or the foot in infants
True or false - nurses should avoid using chlorhexidine as a prepping agen in infants less than 1000 g when administering IV therapy.
True -- chlorhexidine is associated with dermititis in infants
True or false - when administering IV therapy to geriatric clients, the same gauge needle is used as for adults.
False - one should use the smallest gauge needle possible due to the fragility of gerontological veins, less subcutaneous tissue, and thin skin
What is the minimal rate of IV infusion to keep a vein patent?
10 to 15 ml/hr
Why are infusion pumps almost always used with children?
They infuse very small amounts and accurately provide the prescribed volume of IV solution
How often should IV tubing be changed in the case of blood, blood products, and lipid emulsions?
Every 24 hours due to risk of infection and bacterial growth.
When selecting a site for IV therapy, the nurse chooses:
a. A site close to a valve in a vein.
b. A site that is most proximal to the elbow.
c. A site that supports IV therapy for 48 hours or less.
d. A vein that is most distal, avoiding the fingers.
Answer: A vein that is most distal, avoiding the fingers.

Duration of IV therapy: Select a vein that supports IV therapy for at least 72 hours. Begin therapy at the most distal area for long-term therapy. Avoid using the fingers. Choose a soft, straight vein for venipuncture.
As the nurse prepares the IV site, he or she will do which of the following? (Choose all that apply.)

a. Trim excess hair from the site with scissors.
b. Cleanse area with alcohol followed by Betadine.
d. Check to see if the client is allergic to iodine.
e. Prep the skin with alcohol using a vigorous back and forth motion.
f. Shave the area of excess hair.
Correct Answers:
Cleanse area with alcohol followed by Betadine.

Trim excess hair from the site with scissors.

Check to see if the client is allergic to iodine.

The nurse may need to remove excess hair. INS suggests the use of scissors for this. A razor can cause impairment of the skin integrity. Ensure that the client does not have an iodine allergy prior to prepping the skin. Prep with alcohol using a circular motion from inside out and allow to dry for one minute. Next apply Betadine, a germicidal solution. Once it has dried for 1 minute, it is effective for up to 6 hours.
A client states that she is extremely nervous because the last time she had an IV started, she had a bad reaction. To minimize such problems with this IV, the nurse:

a. Explains each step of the procedure in specific detail before beginning the venipuncture.
b. Distracts the client with conversation, keeping the needle out of sight until the last minute.
c. Reassures the client by telling her the number of IVs successfully started by the nurse.
d. Discusses previous clients who have had severe reactions to IV starts.
Answer: Distracts the client with conversation, keeping the needle out of sight until the last minute.

When the client is extremely nervous and has a needle phobia, a vasal-vagal response can ensue. Put the client at ease by engaging in conversation. Keep the needle out of sight until the last minute as this may decrease the severity of the response.
Some central venous access devices (CVAD) have more than one lumen. These multi lumen catheters:
a. Have an increased risk of infiltration.
b. Only work a short while because the small bore clots off.
c. Are beneficial to patient care but are prohibitively expensive.
d. Allow different medications or solutions to be administered simultaneously.
Answer D. A multilumen catheter contains separate ports and means to administer agents. An agent infusing in one port cannot mix with an agent infusing into another port. Thus, agents that would be incompatible if given together can be given in separate ports simultaneously.
Some institutions will not infuse a fat emulsion, such as Intralipid, into central venous access devices (CVAD) because:
a. Lipid residue may accumulate in the CVAD and occlude the catheter.
b. If the catheter clogs, there is no treatment other than removal and replacement.
c. Lipids are necessary only in the most extreme cases to prevent essential fatty acid (EFA) deficiency.
d. Fat emulsions are very caustic.
Answer A. Occlusion occurs with slow infusion rates and concurrent administration of some medications. Lipid occlusions may be treated with 70 percent ethanol or with 0.1 mmol/mL NaOH. Lipids provide essential fatty acids. It is recommended that approximately 4 percent of daily calories be EFAs. A deficiency can quickly develop. Daily essential fatty acids are necessary for constant prostaglandin production. Lipids are almost isotonic with blood.
A male patient is to receive a percutaneously inserted central catheter (PICC). He asks the nurse whether the insertion will hurt. How will the nurse reply?
a. “You will have general anesthesia so you won’t feel anything.”
b. “It will be inserted rapidly, and any discomfort is fleeting.”
c. “The insertion site will be anesthetized. Threading the catheter through the vein is not painful.”
d. “You will receive sedation prior to the procedure.”
Answer C. Pain related to PICC insertion occurs with puncture of the skin. When inserting PICC lines, the insertion site is anesthetized so no pain is felt. The patient will not receive general anesthesia or sedation. Statement 2 is false. Unnecessary pain should be prevented.
The LPN/LVN is starting an IV with orders to hang D5W with 20 mEq of potassium for administering intermittent antibiotics. The nurse will select which vein?

a. A small vein on the underside of the wrist.
b. A small vein in the back of the hand.
c. A large vein in the forearm.
d. A large vein in the antecubital space.
Correct Answer:
c. A large vein in the forearm.

Avoid using the antecubital site unless warranted by an emergency. Hypertonic solutions, potassium chloride, and antibiotics are irritating to the vein walls. Select a large vein to accommodate these solutions.
What are blood volume expanders?
Blood volume expanders are used to increase the volume of blood following a severe loss of blood (e.g., due
to hemorrhage) or plasma (e.g., due to severe burns when large amounts of plasma shift from the bloodstream
to the burn site). Common blood volume expanders are dextran, plasma, and human serum albumin.
When administering a piggyback setup, which solution container should be lower?
It is important for the primary container to be hung lower than the secondary container. By doing so, the center of gravity is lowered in the primary container and the secondary solution is allowed to flow. When the secondary container
is empty, the primary solution will resume administration.
What is a lumen?
The "lumen" is the part of the IV in which a drug can be administered. There are devices such as a "triple lumen" catheter. There is one "lumen" which goes into the patient but the device itself has three ports where different drugs can be administered at the same time.
There are two general types of CVADs. ___ have one end positioned outside the body, while ___ are surgically placed under the skin and require a special needle for access.
Catheters; ports
With both central venous catheters and ports, the opposite end of the tubing is positioned within ___
The Superior Vena Cava
What is the most common reason a CVAD may become occluded?
Blood clot
A nurse suspects that an IV has infiltrated. What steps should he take (select all that apply).
1. STOP infusion
2. Call the doctor
3. Remove IV catheter
4. Elevate the extremity
All choices are correct
True or false - D5W is classified as an Isotonic solution, but works as a hypotonic solution; the glucose is immediately used up by the cells and all that is left is extra water - thus water will move into the cells causing edema (if too much)
Why would you give a patient a hypotonic solution?
Patient is dehydrated - gives cells more water
What is the concentration of 0.9% sodium chloride (isotonic, hypertonic, hypotonic)?
What is the concentration of 3 - 5% sodium chloride (isotonic, hypertonic, hypotonic)?
What is the concentration of 0.45% sodium chloride (isotonic, hypertonic, hypotonic)?
A patient had his IV catheter inserted 48 hours ago to receive antibiotic therapy. During assessment of his IV site the nurse observes redness and tenderness upon palpation. The nurse documents that the IV was discontinued and restarted because of what complication of IV therapy?
1. Clotting of IV catheter
2. Infiltration
3. Phlebitis
4. Puncturing of the opposite side of the vein
3. Phlebitis

Coolness and swelling would be seen with infiltration; there is no data to support the other options
A patient just had a PICC placed in his right antecubital site. When reading the x-ray report verifying correct placement of the catheter, the nurse knows the tip of the catheter is located correctly if it is in which vessel?
1. The inferior vena cava
2. The basilic vein
3. The cephalic vein
4. The superior vena cava
4. The superior vena cava
An obese patient who had a right masectomy several years ago has better veins in her right hand but is left handed. Where should the nurse place the IV catheter?
1. In her right hand
2. In her left lower arm
3. Wherever the patient wants
4. In her right antecubital site
2. In the left lower arm

Although it is desirable to place in IV infusion in the patient's nondominant hand, this patient has a medical condition that dictates that the IV catheter be placed in her dominant hand or arm.
The physician discontinued a patient's anticoagulant therapy. What nursing intervention is most appropriate after the nurse removes the IV catheter from his hand?
1. Apply pressure to the IV site for 5 minutes
2. Convert the catheter to an intermittent heparin lock for 24 hours
3. Encourage the patient to keep his hand elevated for 10 minutes
4. Use a warm compress at the site for several minutes
1. Apply pressure for 5 minutes

The patient is susceptible to bleeding, so pressure should be applied whenver a device is removed from his body while he still has prolonged bleed times. You or the patient can apply pressure for the required time.
A nurse is preparing a blood transfusion infusion set. Which solution should be used to prime the tubing?
1. 0.45% sodium chloride (1/2 NS)
2. Dextrose 5% in 0.45% NS
3. 0.9% sodium chloride (NS)
4. Dextrose 5% in 0.9% NS
3. Normal saline

Normal saline is the only IV solution that can be used with blood because of its isotonic quality. Dextrose solutions cause hemolysis of the RBCs.
A patient with A - blood type needs a blood transfusion. Which blood types are appropriate for him to receive?
1. A+ or A-
2. A- or O+
3. A- or O-
4. A+ or AB-
3. Only negative blood types can be given to a patient with a negative blood type.
A patient is to receive blood that has been stored for quite some time. What recent lab value should the nurse check before administering the unit?
1. Sodium
2. Hematocrit
3. Hemoglobin
4. Potassium
4. When blood is stored, there is a continued destruction of blood cells, which release K into the plasma; if the blood is transfused rapidly, there may be transient hyperkalemia before the K is reabsorbed.
A patient is to receive a blood transfusion. Which nursing action has the greatest impact on reducing a potential transfusion reaction?
1. Administering an antihistamine 15 minutes prior to transfusion
2. Comparing the patient's ID bracelet with the blood bag label number
3. Ensuring that the patient knows what his or her blood type is
4. Obtaining the patient's previous transfusion history
2. Comparing the patient's ID bracelet with the blood bag label number is the most important step to take.
A patient receiving a blood transfuion begins having signs and symptoms of a transfusion reaction. Other than stopping the transfusion and assessing vital signs, what else should the nurse do
1. Hang a new infusion setup with D5W to maintain an access for meds
2. Finish infusing the blood remaining in the tubing, then flush the tubing with normal saline hanging on the Y-tubing
3. Keep the existing tubing patent with a dextrose solution in case diphenhydramine is needed
4. Hang a new infusion setup with NS to maintain an IV access
4. It is essential to maintain an IV access, but you do not want the patient to receive any more of the current blood. Another blood administration set should be primed with a new bag of normal saline in case more blood needs to be given. Keep the old blood bag and saline as well as the administration set and send them to the appropriate department for analysis.

True or false - a marker or sharpie may be used to note day, time and initials on an IV bag.
False - ink may absorb into bag.
What is an IV piggyback? How is it often administered?
An intravenous (IV) piggyback is a way to administer medication through an intravenous tube that is inserted into a patient's vein. This can be an antibiotic or another type of medication that needs to be diluted and administered slowly. The medication in an IV piggyback is mixed in a small amount of compatible fluid, such as normal saline or dextrose with saline.

The IV piggyback is aptly named because the medication is given on top of the main intravenous solution. This allows for the intermittent infusion of medications at specific times. The piggyback infusion usually is hung higher than the main IV solution and is connected to a port in the main tubing. Hanging the IV piggyback higher than the main solution causes it to infuse faster than the main solution. A pump may also be used instead of gravity.
What is an IV push?
The intravenous or IV push or bolus is a means of delivering additional medication through an intravenous line, administered all at once, over a period of a minute or two. This contrasts with IV drip techniques where medicine is slowly delivered from an IV bag. An IV push has the advantage of being able to give extra medicine, as needed, without having to inject the patient elsewhere, and it can rapidly get this medicine into the body since it’s injected directly into the bloodstream. This technique also comes with noted cautions, since not all medicines can be delivered this way and some may cause extreme irritation or toxically high blood levels of a medicine, if they are given too quickly.
True or false - meds can be added to an existing IV container for administration.
False - Always add meds to a new container, not to an already hung IV container
A piggyback container usually has how many mLs and is connected to what y-port?
25-150mL; upper
A tandem container usually has how many mLs and is connected to what y-port?
25-250mL; lower
What is a mini-infusion pump?
Battery operated pump that delivers very small amounts (5-60mL) within controlled infusion times using standard syringes.
What should the nurse do if meds administered via IV push begin to cloud the IV fluid?
If IV fluid becomes cloudy, STOP. It means the IV med is incompatible with the fluid.
This type of cath is surgically inserted through a tunnel in the sub q tissue, usually between clavicle and nipple, into the internal jugular or subclavian vein, tip resting in superior vena cava; it can remain in place for months to years.
Tunneled catheter
What is the advantage of a tunneled catheter?
Tunneling decreases the risk for phlebitis and infection since it doesn’t go directly in the vein but the tissue for awhile first.
How often does the dressing of a CVAD need to be changed?
Gauze dressing needs to be changed every 48 hours, transparent dressings need to be cared for every 7 days and as needed.
During a blood transfusion, the nurse should stay with the patient for the first ___ (time), and flow rate during this time should be ___.
Stay with the patient for the first 15 minutes, and flow rate during this time should be 2mL/minute or 20gtt/min (using MACROdrip rate of 10gtt/mL)
