N322 Flash cards Questions With Complete Solutions
A patient for whom an intravenous antibiotic is prescribed has a
multilumen central line in place for central parenteral nutrition
(CPN). What should the nurse do?
A. Infuse the antibiotic through another lumen of the multilumen
central line.
B. Interrupt the CPN infusion only long enough to administer
the antibiotic.
C. Rearrange the antibiotic administration schedule so it does
not interfere with the CPN.
D. Ask the prescriber if the route of administration for the
antibiotic can be changed. Correct Answers Answer: Infuse
the antibiotic through another lumen of the multilumen central
line.
Rational:
IV medications and blood should be infused through a different
line or lumen than CPN. The parenteral nutrition must not be
interrupted for medication administration. Intravenous
medications are to be infused through an alternative line or
lumen, not through the same lumen or port being used for
parenteral nutrition. It would be inappropriate for the nurse to
ask the prescriber to change the route of administration for the
antibiotic. Another lumen can be used, or another line can be
placed for intravenous medication administration.
A patient is prescribed to receive an infusion of 20% fat
emulsion. The nurse informs the patient that this infusion will
last how long?
A. 2 hours
,B. At least 4 hours
C. No more than 6 hours
D. At least 8 hours Correct Answers Answer: At least 8 hours
Rational:
Twenty percent fats are infused over at least 8 hours.
A patient's central parenteral nutrition (CPN) order has been
changed to a different solution, and the present solution is to be
discontinued immediately. What should the nurse do until the
new solution is delivered by the pharmacy?
A. Discontinue the present CPN solution, and clamp the catheter
hub.
B. Continue the present CPN solution, but readjust the flow to a
keep-vein-open (KVO) rate.
C. Hang an infusion of 0.9% normal saline at the same infusion
rate as the CPN.
D. Hang an infusion of 10% dextrose in water at the same
infusion rate as the CPN. Correct Answers Answer: Hang an
infusion of 10% dextrose in water at the same infusion rate as
the CPN.
Rational:
If CPN must be discontinued suddenly, a solution of 10%
dextrose in water can be given at the same infusion rate in order
to prevent hypoglycemia. Discontinuing the present CPN
solution could cause the patient to develop hypoglycemia.
Continuing the present CPN solution at a KVO rate could cause
the patient to develop hypoglycemia. Normal saline will not
prevent the patient from developing hypoglycemia.
,After changing the intravenous (IV) tubing on a patient's
primary infusion, the nurse notes air bubbles in the tubing. How
would the nurse remove them?
A. Begin the process again.
B. Add more fluid to the drip chamber.
C. Inject a syringe of saline into the tubing to vent the air
bubbles.
D. Close the clamp, stretch the tubing downward, and flick the
tubing. Correct Answers Answer: Close the clamp, stretch the
tubing downward, and flick the tubing.
Rational:
To remove air bubbles from the tubing, the nurse would close
the roller clamp, stretch the tubing downward, and flick the
tubing, so that the air bubbles will rise into the drip chamber.
The nurse need not repeat the entire process. Adding more fluid
to the drip chamber will not remove the bubbles. The tubing
should not be compromised by inserting a needle through it.
After drawing blood from a central venous access device
(CVAD), which action would minimize the patient's risk for
infection when reconnecting prescribed intravenous fluids?
A. Wearing clean gloves
B. Changing the IV tubing
C. Cleansing the IV needleless connector and the end of the IV
tubing with a 2% chlorhexidine swab
D. Aspirating for blood return before flushing the catheter
Correct Answers Answer: Cleansing the IV needleless
connector and the end of the IV tubing with a 2% chlorhexidine
swab
, Rational:
To reduce the patient's risk for infection, the nurse would
cleanse the needleless connector and the end of the IV tubing
with chlorhexidine swabs before reconnecting the fluids.
Wearing clean gloves would not minimize the patient's risk for
infection when reconnecting intravenous fluids. The IV tubing
does not need to be changed. Doing so may or may not reduce
the patient's risk for infection. Aspirating for blood return before
flushing the catheter would have no effect on the patient's risk
for infection.
After drawing blood from a patient's central venous access
device (CVAD), what would the nurse do to ensure that the
device resumes proper functioning?
A. Discard the initial 5 mL of aspirated blood.
B. Apply an antiseptic to the injection cap.
C. Wear clean treatment gloves during the procedure.
D. Flush the catheter with preservative-free 0.9% sodium
chloride, per agency policy. Correct Answers Answer: lush the
catheter with preservative-free 0.9% sodium chloride, per
agency policy.
Rational:
Flushing the catheter with preservative-free 0.9% sodium
chloride minimizes the risk of clot formation at the catheter tip
and ensures continued proper functioning of the device.
Discarding the initial 5 mL of aspirated blood would have no
effect on the function of the device. Applying an antiseptic to
the injection cap would have no effect on the function of the
device. Wearing clean treatment gloves would have no effect on
the function of the device.
