Section 1: Cardiovascular Disorders
1. A nurse is assessing a client with heart failure.
Which finding is the earliest sign of left-sided heart
failure?
A) Peripheral edema
B) Jugular venous distension
C) Dyspnea on exertion
D) Hepatomegaly
,Rationale: Dyspnea on exertion is the earliest
clinical manifestation of left-sided heart failure
due to pulmonary congestion. Peripheral edema,
JVD, and hepatomegaly are signs of right-sided
heart failure.
2. A client with acute myocardial infarction reports
chest pain rated 8/10. Which is the nurse's priority
action?
A) Administer prescribed nitroglycerin and
reassess
B) Document the pain
C) Offer a snack
D) Call family
Rationale: Chest pain in MI is life-threatening.
Administering prescribed nitroglycerin addresses
myocardial ischemia. Documentation, food intake,
and family notification are secondary to patient
stabilization.
3. A nurse is caring for a client with heart failure
who reports a sudden weight gain of 3 pounds in 2
days. Which action should the nurse take first?
,A) Assess for signs of fluid overload
B) Restrict the client's fluid intake
C) Administer a diuretic as prescribed
D) Document the weight gain
Rationale: A sudden weight gain of 2-3 pounds in
24 hours or 5 pounds in a week indicates fluid
retention. The nurse should first assess for
worsening heart failure signs such as crackles,
edema, and dyspnea before intervening.
4. A client with hypertension is prescribed lisinopril.
Which adverse effect should the nurse monitor for?
A) Hyperkalemia
B) Hypokalemia
C) Hypernatremia
D) Hypocalcemia
Rationale: Lisinopril is an ACE inhibitor that can
cause hyperkalemia by reducing aldosterone
secretion. The nurse should monitor serum
potassium levels and signs of hyperkalemia such as
muscle weakness and cardiac arrhythmias.
, 5. A nurse is monitoring a client receiving a blood
transfusion. Which of the following symptoms
indicates a hemolytic reaction?
A) Bradycardia
B) Urticaria and itching
C) Distended neck veins
D) Low back pain and hypotension
Rationale: Low back pain, hypotension, and fever
are classic signs of an acute hemolytic transfusion
reaction due to ABO incompatibility. Urticaria
indicates an allergic reaction; distended neck veins
indicate fluid overload.
6. A client with angina pectoris reports chest pain.
Which action should the nurse take first?
A) Administer sublingual nitroglycerin
B) Obtain a 12-lead ECG
C) Administer morphine sulfate
D) Check serum cardiac enzymes
Rationale: Sublingual nitroglycerin is the first-line
treatment for angina to promote coronary
