Question 1
A nurse is preparing to administer total parenteral nutrition to a
client. Which of the following actions should the nurse take?
A. Obtain the client's weight three times a week.
B. Check the client's WBC count daily.
C. Keep the solution refrigerated until 1 hr before infusion.
D. Change the solution every 36 hrs.
Answer: C. Keep the solution refrigerated until 1 hr before infusion.
Rationale:
TPN solutions should generally be stored in the refrigerator until they
are needed. The solution should be removed approximately 1 hour
before administration so it can reach room temperature before
infusion. Administering a cold solution can cause discomfort and other
complications.
,Question 2
A nurse is preparing to administer a medication to a client. Using
the rights of medication administration, which of the following
actions should the nurse take to ensure the right medication is
administered to the client?
A. Ask another nurse to check the medication dosage prior to
administration.
B. Verify a written order with the medication administration record.
C. Use two client identifiers prior to administering the medication.
D. Document the full name of the prescribed medication after
administration.
Answer: C. Use two client identifiers prior to administering the
medication.
Rationale:
Using two client identifiers—such as the client's name and date of
birth—is a fundamental safety measure before medication
administration. It helps ensure that the medication is given to the right
client.
Question 3
A nurse is preparing to mix short-acting (regular) insulin with NPH
insulin in the same syringe. Which action should the nurse take?
A. Withdraw the NPH insulin before the short-acting insulin.
B. Shake the NPH vial vigorously before withdrawing the insulin.
C. Withdraw the short-acting insulin before withdrawing the NPH
insulin.
,D. Use a separate syringe for each insulin when the two insulins are
prescribed to be mixed.
Correct Answer: C. Withdraw the short-acting insulin before
withdrawing the NPH insulin.
Rationale: When mixing regular/short-acting insulin with NPH insulin,
the nurse follows “clear before cloudy.” Regular insulin is clear and
should be drawn up before cloudy NPH insulin. This prevents NPH
from contaminating the regular insulin vial.
Sequence:
Air into NPH → air into regular → withdraw regular → withdraw
NPH.
Question 4
A nurse is reviewing the list of current medications for a client who
has a new prescription for nitroglycerin. The nurse should identify
which of the following client medications is contraindicated for use
with nitroglycerin?
A. Sildenafil
B. Gemfibrozil
C. Lansoprazole
D. Diazepam
Correct Answer: A. Sildenafil
Rationale:
Sildenafil, a phosphodiesterase-5 (PDE-5) inhibitor, is contraindicated
with nitroglycerin and other nitrates. Both medications cause
vasodilation, and their combined effects can produce a severe,
potentially life-threatening drop in blood pressure.
, Question 5
A nurse is reviewing the medication administration record for a
client who has cancer and is receiving morphine via a patient-
controlled analgesia (PCA) pump. Which of the following
prescriptions should the nurse clarify with the provider?
A. Nalbuphine
B. Acetaminophen
C. Ondansetron
D. Insulin glargine
Correct Answer: A. Nalbuphine
Rationale:
Nalbuphine is an opioid agonist-antagonist. Giving it to a client
receiving morphine, a full opioid agonist, can interfere with
morphine's analgesic effect and may precipitate withdrawal or reduce
pain control. The prescription should therefore be clarified.
Key point: Avoid opioid agonist-antagonists such as nalbuphine in
clients receiving full opioid agonists unless specifically directed.
Question 6
A nurse is administering medication to a client who weighs 132 lb.
The prescription reads chloramphenicol 50 mg/kg/day in 4 divided
doses. Available is chloramphenicol 100 mg/mL. How many mL
should the nurse give with each dose?
