,Section 1: Cardiovascular Medications (Questions 1–20)
1. A client is prescribed digoxin for heart failure. Which
finding indicates digoxin toxicity?
A. Heart rate of 62 beats per minute
B. Serum potassium of 4.0 mEq/L
C. Yellow-green halos around lights
D. Blood pressure of 110/70 mm Hg
Correct Answer: C
Rationale: Visual disturbances (yellow-green halos, blurred
vision) are classic signs of digoxin toxicity. Other signs: nausea,
vomiting, bradycardia, arrhythmias. Normal HR and potassium
are not toxic. Nursing implication: monitor digoxin levels
(therapeutic 0.5-0.8 ng/mL) and hold for HR <60.
2. A client is receiving IV furosemide (Lasix). Which
laboratory value requires immediate notification of the
provider?
A. Serum sodium 135 mEq/L
B. Serum potassium 2.8 mEq/L
C. Blood glucose 110 mg/dL
D. Creatinine 0.9 mg/dL
,Correct Answer: B
Rationale: Furosemide is a loop diuretic that causes potassium
wasting. Hypokalemia (K <3.5) can lead to cardiac
dysrhythmias, especially in clients on digoxin. Nursing
implication: monitor potassium, encourage potassium-rich
foods, and report hypokalemia.
3. A client on warfarin (Coumadin) has an INR of 4.5. The
client has no signs of bleeding. What is the most
appropriate nursing action?
A. Administer vitamin K intramuscularly
B. Hold the next dose and notify the provider
C. Give the next dose as scheduled
D. Increase the dose to lower INR faster
Correct Answer: B
Rationale: Therapeutic INR for most indications is 2.0-3.0. INR
of 4.5 is above target. Without bleeding, hold the dose and
notify provider; vitamin K is given for active bleeding or very
high INR (>10). Nursing implication: monitor for bleeding
(bruising, hematuria, gums).
4. A client is started on lisinopril (an ACE inhibitor). Which
adverse effect should the nurse teach the client to report
, immediately?
A. Dry cough
B. Swelling of the lips and tongue
C. Dizziness when standing
D. Loss of taste
Correct Answer: B
Rationale: Angioedema (swelling of lips, tongue, throat) is a
rare but life-threatening adverse effect of ACE inhibitors. Dry
cough (A) is common but not emergent. Dizziness is expected
with initial dosing. Nursing implication: discontinue drug and
seek emergency care if angioedema occurs.
5. A nurse is administering metoprolol (a beta-blocker).
Which assessment is most important before administration?
A. Blood pressure and heart rate
B. Respiratory rate
C. Serum potassium
D. Blood glucose
Correct Answer: A
Rationale: Beta-blockers lower heart rate and blood pressure.
Hold if HR <60 or SBP <90. Nursing implication: assess apical
