SECTION 1: CARDIOVASCULAR DISORDERS (Questions
1-50)
QUESTION 1
A patient with heart failure has an ejection fraction of 35%. This indicates:
A. Preserved systolic function
B. Reduced systolic function (HFrEF)
C. Normal diastolic function
D. Severe valvular disease
Correct Answer: B. Reduced systolic function (HFrEF)
*Rationale: * Normal ejection fraction is 55-70%. An EF of 35% indicates
systolic heart failure with reduced ejection fraction (HFrEF). This means the
left ventricle is not pumping effectively.
QUESTION 2
,A patient on amlodipine reports flushing and headache. The nurse's best
response is:
A. "These are expected side effects that often improve with time."
B. "Stop the medication immediately and call 911."
C. "You are having an allergic reaction."
D. "This indicates your blood pressure is now normal."
Correct Answer: A. "These are expected side effects that often improve
with time."
*Rationale: * Amlodipine is a calcium channel blocker that causes
vasodilation, leading to flushing, headache, and peripheral edema. These
are common side effects that often resolve as the body adjusts to the
medication.
QUESTION 3
A patient with unstable angina is prescribed clopidogrel. Which teaching
point is most important?
A. "Take with grapefruit juice to increase absorption."
B. "Notify the provider if you notice black, tarry stools."
C. "This medication will dissolve any existing clots."
D. "You will not need aspirin while taking this."
,Correct Answer: B. "Notify the provider if you notice black, tarry
stools."
*Rationale: * Clopidogrel is an antiplatelet medication that increases the
risk of bleeding. Black, tarry stools indicate gastrointestinal bleeding and
require immediate notification of the provider.
QUESTION 4
A patient on digoxin reports nausea, vomiting, and visual disturbances.
What is the priority nursing action?
A. Administer the next dose as scheduled
B. Hold the dose and assess the apical pulse
C. Encourage the patient to eat a small snack
D. Notify the provider immediately
Correct Answer: B. Hold the dose and assess the apical pulse
*Rationale: * Nausea, vomiting, and visual disturbances are signs of digoxin
toxicity. The nurse should hold the dose, assess the apical pulse, and notify
the provider based on assessment findings.
QUESTION 5
, A patient with chronic heart failure is prescribed metoprolol succinate.
Which assessment finding requires the nurse to hold the medication?
A. Heart rate of 68 bpm
B. Blood pressure of 130/80 mmHg
C. Heart rate of 54 bpm
D. Respiratory rate of 16 breaths/min
Correct Answer: C. Heart rate of 54 bpm
*Rationale: * Metoprolol is a beta-blocker that decreases heart rate. The
medication should be held if the heart rate is below 60 bpm (or per
provider order).
QUESTION 6
A patient with hypertension is prescribed lisinopril. The nurse should
monitor for which adverse effect?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypomagnesemia
Correct Answer: A. Hyperkalemia
