Question 1
A nurse is preparing to administer a medication to a patient. Which action is most
critical to ensure patient safety?
A. Assess the patient's pain level
B. Verify the patient's identity using two identifiers
C. Review the patient's laboratory results
D. Educate the patient about the medication
Answer: B
Verifying patient identity using two identifiers (e.g., name and date of birth) is the
most critical safety step to prevent medication errors. This is part of the "right
patient" in the rights of medication administration and is required by The Joint
Commission before any medication is given.
,Question 2
A nurse is caring for a client who has a medication with a narrow therapeutic
index. Which action should the nurse take?
A. Monitor serum drug levels closely
B. Administer the medication with food
C. Double the dose if the client misses a dose
D. Discontinue the medication if side effects occur
Answer: A
Medications with a narrow therapeutic index (e.g., digoxin, lithium, warfarin,
phenytoin, aminoglycosides) require close monitoring of serum drug levels
because the difference between therapeutic and toxic doses is small. Monitoring
serum levels helps maintain therapeutic efficacy while avoiding toxicity.
Question 3
A client is prescribed digoxin for heart failure. Which of the following findings
indicates digoxin toxicity?
A. Heart rate of 68 beats per minute
B. Nausea and vomiting
C. Blood pressure of 140/90 mm Hg
D. Weight gain
Answer: B
Nausea, vomiting, anorexia, and visual disturbances (yellow-green halos) are early
signs of digoxin toxicity. Bradycardia is also a sign, but a heart rate of 68 is within
normal limits. Hypokalemia increases the risk of digoxin toxicity.
Question 4
A nurse is reviewing the laboratory data of a client who is receiving heparin
therapy. Which of the following laboratory values should the nurse monitor to
evaluate the effectiveness of the therapy?
A. PT
B. INR
C. aPTT
D. Platelet count
Answer: C
,The aPTT (activated partial thromboplastin time) is used to monitor heparin
therapy. PT and INR are used to monitor warfarin therapy. Platelet count is
monitored to assess for heparin-induced thrombocytopenia (HIT).
Question 5
A client is prescribed warfarin for atrial fibrillation. Which laboratory test should
the nurse review prior to administration?
A. PT and INR
B. Total iron-binding capacity
C. WBC count
D. PTT
Answer: A
The prothrombin time (PT) and INR are used to monitor the therapeutic effects of
warfarin. The target INR for most indications is 2-3. Reviewing these results before
administration is critical to prevent bleeding complications.
Question 6
A nurse is providing teaching to a client who has a new prescription for warfarin.
Which of the following statements by the client indicates understanding of the
teaching?
A. "I will take ibuprofen for pain."
B. "I will increase my intake of leafy green vegetables."
C. "I will wear a medical alert bracelet."
D. "I will stop taking the medication if I have a headache."
Answer: C
Wearing a medical alert bracelet is important for clients taking warfarin to alert
healthcare providers in case of emergency. Ibuprofen increases bleeding risk, leafy
green vegetables contain vitamin K and should be consumed consistently, and the
medication should not be stopped without provider guidance.
Question 7
A client is prescribed enoxaparin (Lovenox) for deep vein thrombosis prophylaxis.
Which of the following statements about enoxaparin is correct?
A. It is administered orally
, B. It does not require routine monitoring of aPTT
C. It is a vitamin K antagonist
D. It has a longer half-life than unfractionated heparin
Answer: B
Enoxaparin is a low molecular weight heparin that does not require routine
monitoring of aPTT due to its predictable pharmacokinetics. It is administered
subcutaneously and is not a vitamin K antagonist.
Question 8
A nurse is assessing a client who is receiving IV heparin and notes a sudden drop
in platelet count. The nurse should suspect which of the following?
A. Heparin-induced thrombocytopenia
B. Hemolytic anemia
C. Disseminated intravascular coagulation
D. Allergic reaction
Answer: A
A sudden drop in platelet count in a client receiving heparin is a sign of heparin-
induced thrombocytopenia (HIT), a serious immune-mediated reaction that can
lead to thrombosis. The nurse should notify the provider immediately and
discontinue heparin.
Question 9
A client is prescribed clopidogrel (Plavix) after coronary stent placement. Which
statement by the client indicates understanding?
A. "I will take this medication with food to prevent stomach upset."
B. "I will report any unusual bleeding or bruising."
C. "I can stop this medication if I have no chest pain."
D. "I can take ibuprofen if I have a headache."
Answer: B
Clopidogrel is an antiplatelet medication that increases bleeding risk. Clients
should report signs of bleeding such as easy bruising or dark stools. Ibuprofen
increases bleeding risk and should be avoided.
