Detailed Rationales
Question 1
Clinical Scenario
A 68-year-old male client with a history of atrial fibrillation is being
discharged home with a new prescription for warfarin. The client has
a therapeutic international normalized ratio (INR) of 2.5. The nurse is
providing discharge education regarding dietary and lifestyle
modifications to ensure medication safety.
Question Stem
Which statement by the client indicates a correct understanding of
the teaching?
A. "I will increase my daily intake of leafy green vegetables like
spinach to improve my blood counts." B. "I can take over-the-
counter ibuprofen if I develop a mild headache." C. "I will use an
electric razor for shaving instead of my traditional blade razor." D. "I
should stop taking the warfarin if my home INR monitor reads 2.0."
Correct Answer
,Correct Answer: C. "I will use an electric razor for shaving instead of
my traditional blade razor."
Detailed Rationale
The correct answer is C. Using an electric razor is a crucial safety
measure for clients on anticoagulants like warfarin to minimize the
risk of cuts and subsequent bleeding. Warfarin works by inhibiting
vitamin K-dependent clotting factors in the liver, significantly
increasing the risk of hemorrhage. Option A is incorrect because
spinach is high in vitamin K, which antagonizes warfarin; clients
should maintain a consistent, not increased, dietary intake of
vitamin K to prevent fluctuations in INR. Option B is incorrect
because nonsteroidal anti-inflammatory drugs (NSAIDs) like
ibuprofen inhibit platelet function and increase bleeding risk, so
they should be strictly avoided. Option D is incorrect because an
INR of 2.0 to 3.0 is the standard therapeutic range for most
indications like atrial fibrillation, so the medication should not be
stopped. Nurses must educate clients on comprehensive bleeding
precautions, including using soft-bristled toothbrushes, avoiding
contact sports, and reporting any unusual bruising. Clinical
judgment requires the nurse to reinforce that medication adherence
and regular INR monitoring are essential to ensure therapeutic
levels and prevent life-threatening toxicity.
Learning Objective
After completing this question, the learner should be able to: •
Identify appropriate bleeding precautions for clients taking oral
anticoagulants. • Recognize the impact of dietary vitamin K on
,warfarin therapy. • Educate patients on medications to avoid while
on warfarin. • Interpret therapeutic INR ranges for atrial fibrillation.

Question 2
Clinical Scenario
A 55-year-old female client with chronic kidney disease (CKD) stage
4 is experiencing severe fatigue, weakness, and shortness of breath.
Her laboratory results reveal a hemoglobin level of 8.2 g/dL. The
provider prescribes epoetin alfa.
Question Stem
Which finding should the nurse identify as the expected therapeutic
response to this medication?
A. A decrease in the white blood cell count. B. An increase in energy
levels and hemoglobin concentration. C. A decrease in blood
pressure. D. An increase in the platelet count.
Correct Answer
Correct Answer: B. An increase in energy levels and hemoglobin
concentration.
Detailed Rationale
The correct answer is B. Epoetin alfa is a recombinant form of
erythropoietin, a glycoprotein that stimulates the bone marrow to
produce red blood cells. The expected therapeutic response is an
increase in hemoglobin and hematocrit levels, which will
, subsequently improve tissue oxygenation and resolve symptoms of
anemia such as fatigue and shortness of breath. Option A is
incorrect because epoetin alfa specifically targets the erythroid
lineage and does not significantly affect white blood cell production.
Option C is incorrect because epoetin alfa is actually associated
with an increased risk of hypertension, not a decrease in blood
pressure; blood pressure must be carefully monitored and
controlled during therapy. Option D is incorrect because the
medication does not stimulate thrombopoiesis (platelet
production). The nurse should monitor the client's hemoglobin
levels closely, ensuring they do not exceed 11 g/dL, as targeting
higher levels increases the risk of fatal cardiovascular events,
including myocardial infarction and stroke.
Learning Objective
After completing this question, the learner should be able to: •
Identify the expected therapeutic outcomes of erythropoiesis-
stimulating agents. • Recognize the mechanism of action of epoetin
alfa. • Monitor for adverse effects associated with hematopoietic
growth factors. • Evaluate laboratory values to determine
medication efficacy.
