Questions 1–50
1. A nurse is preparing to administer digoxin to a patient with
heart failure. Which assessment finding should cause the nurse
to withhold the medication and notify the provider?
A. Blood pressure of 128/76 mm Hg
B. Respiratory rate of 18 breaths/minute
C. Apical pulse of 54 beats/minute
D. Oxygen saturation of 96%
Correct Answer: C. Apical pulse of 54 beats/minute
Rationale: Digoxin can slow the heart rate. An apical pulse below 60
beats/minute is a contraindication to administration because of the
increased risk of bradycardia and cardiac dysrhythmias. The nurse
should withhold the medication and notify the healthcare provider for
further instructions.
2. A patient taking warfarin asks the nurse why regular
laboratory monitoring is necessary. Which response by the
nurse is most appropriate?
A. “The test checks your kidney function.”
B. “The test determines whether the medication is preventing
,harmful clotting.”
C. “The test measures your blood sugar level.”
D. “The test evaluates your liver enzymes only.”
Correct Answer: B. “The test determines whether the medication is
preventing harmful clotting.”
Rationale: Patients taking warfarin require regular International
Normalized Ratio (INR) testing to ensure therapeutic anticoagulation
while minimizing the risk of bleeding. Monitoring helps determine
whether dosage adjustments are necessary.
3. Which adverse effect should the nurse monitor for in a patient
receiving furosemide?
A. Hyperkalemia
B. Hypokalemia
C. Hypertension
D. Bradycardia
Correct Answer: B. Hypokalemia
Rationale: Furosemide is a loop diuretic that promotes potassium
excretion, increasing the risk of hypokalemia. The nurse should
monitor electrolyte levels, cardiac rhythm, and signs such as muscle
weakness or cramping.
4. A nurse is teaching a patient about nitroglycerin tablets.
Which statement by the patient indicates correct
understanding?
A. “I will swallow the tablet with water immediately.”
B. “I will place the tablet under my tongue.”
C. “I can take unlimited tablets for chest pain.”
D. “I should store the tablets in the bathroom cabinet.”
Correct Answer: B. “I will place the tablet under my tongue.”
,Rationale: Nitroglycerin sublingual tablets should be placed under the
tongue and allowed to dissolve for rapid absorption. They should be
stored in their original dark container away from moisture and heat.
Patients should seek emergency assistance if chest pain persists after
recommended doses.
5. Which medication classification does metformin belong to?
A. Sulfonylurea
B. Biguanide
C. Beta blocker
D. Calcium channel blocker
Correct Answer: B. Biguanide
Rationale: Metformin is a biguanide oral antidiabetic medication
commonly used to treat type 2 diabetes mellitus. It works primarily by
decreasing hepatic glucose production and improving insulin
sensitivity.
6. A patient receiving morphine reports severe itching after
administration. What is the nurse’s priority action?
A. Document the finding only
B. Assess the patient for an allergic reaction
C. Encourage increased fluid intake
D. Discontinue all medications immediately
Correct Answer: B. Assess the patient for an allergic reaction
Rationale: Morphine can cause histamine release and itching. The
nurse should assess for signs of a serious allergic reaction, including
rash, swelling, or respiratory distress, before determining appropriate
interventions.
7. Which laboratory value is most important for the nurse to
monitor in a patient receiving heparin therapy?
, A. Hemoglobin A1C
B. Activated partial thromboplastin time (aPTT)
C. Serum calcium
D. Creatinine kinase
Correct Answer: B. Activated partial thromboplastin time (aPTT)
Rationale: Heparin therapy is monitored using the activated partial
thromboplastin time to ensure therapeutic anticoagulation and reduce
the risk of bleeding complications.
8. A patient taking lisinopril develops a persistent dry cough.
Which explanation should the nurse provide?
A. “This is a common side effect of ACE inhibitors.”
B. “This means the medication is not working.”
C. “This indicates fluid overload.”
D. “This is caused by dehydration only.”
Correct Answer: A. “This is a common side effect of ACE
inhibitors.”
Rationale: ACE inhibitors such as lisinopril commonly cause a dry,
persistent cough because of increased bradykinin levels. The
healthcare provider may prescribe an alternative medication if the
cough becomes bothersome.
9. Which instruction is most important for a patient taking
tetracycline?
A. Take the medication with dairy products
B. Avoid sun exposure and use sunscreen
C. Crush the medication before taking it
D. Take the medication only at bedtime
Correct Answer: B. Avoid sun exposure and use sunscreen
