* INTRODUCTION
* This assessment is designed to strengthen comprehensive Adult Health 1
knowledge through examination-style multiple-choice questions. It evaluates foundational
concepts, pathophysiology, assessment findings, diagnostic interpretation, pharmacologic
and nonpharmacologic management, nursing interventions, safety, prioritization, and clinical
decision-making. Questions progress from foundational knowledge to application and
higher-level reasoning so learners can practice distinguishing closely related conditions and
selecting the most appropriate nursing action. The rationales emphasize why the correct
answer is best and clarify important clinical distinctions. This material is intended for
educational preparation and practice; it does not represent confidential, leaked, unreleased,
or guaranteed official examination questions.*
SECTION ONE: QUESTIONS 1–100
CARDIOVASCULAR AND HEMODYNAMIC DISORDERS
Question 1. A client with left-sided heart failure develops increasing dyspnea and bilateral
crackles. Which complication is the nurse most concerned about?
A. Peripheral neuropathy
B. Pulmonary edema
,C. Deep-vein thrombosis
D. Urinary retention
Correct Answer: B. Pulmonary edema
Explanation: Left-sided heart failure causes blood to back up into the pulmonary circulation.
Increased pulmonary capillary pressure can force fluid into the alveoli, producing crackles,
dyspnea, hypoxemia, and potentially acute pulmonary edema.
Question 2. Which assessment finding is most characteristic of right-sided heart failure?
A. Pulmonary crackles
B. Pink frothy sputum
C. Dependent peripheral edema
D. Orthopnea
Correct Answer: C. Dependent peripheral edema
Explanation: Right-sided heart failure causes systemic venous congestion. Common
manifestations include dependent edema, jugular venous distention, hepatomegaly, and
weight gain from fluid retention.
Question 3. A client taking furosemide for heart failure is at greatest risk for which
electrolyte abnormality?
A. Hypercalcemia
B. Hyperkalemia
C. Hypokalemia
D. Hypermagnesemia
Correct Answer: C. Hypokalemia
Explanation: Furosemide is a loop diuretic that increases urinary sodium and water
excretion and also promotes potassium loss. Serum potassium should therefore be
monitored.
Question 4. Which finding in a client with heart failure requires the most immediate follow-
up?
A. Weight gain of 2 kg over several days
B. Mild ankle edema at the end of the day
C. Heart rate of 78/min
D. Blood pressure of 128/76 mm Hg
,Correct Answer: A. Weight gain of 2 kg over several days
Explanation: Rapid weight gain suggests fluid retention and worsening heart failure. Daily
weight is a sensitive indicator of changes in fluid status.
Question 5. A client taking digoxin reports nausea, poor appetite, and seeing yellow-green
halos around lights. What should the nurse suspect?
A. Digoxin toxicity
B. Hyperglycemia
C. Acute hypertension
D. Iron deficiency
Correct Answer: A. Digoxin toxicity
Explanation: Gastrointestinal symptoms and visual disturbances are classic manifestations of
digoxin toxicity. Bradycardia and dysrhythmias may also occur.
Question 6. Which medication class decreases angiotensin II formation and is commonly
used in heart failure and hypertension?
A. ACE inhibitors
B. Calcium supplements
C. Anticholinergics
D. Proton-pump inhibitors
Correct Answer: A. ACE inhibitors
Explanation: ACE inhibitors reduce conversion of angiotensin I to angiotensin II, decreasing
vasoconstriction and aldosterone-mediated fluid retention. They can also reduce cardiac
remodeling.
Question 7. A client taking lisinopril develops swelling of the lips and tongue. What is the
nurse's priority action?
A. Administer the next dose with food
B. Hold the medication and assess the airway
C. Encourage increased oral fluids
D. Place the client in a supine position
Correct Answer: B. Hold the medication and assess the airway
, Explanation: Facial and tongue swelling can indicate ACE-inhibitor-associated angioedema,
which can rapidly compromise the airway. The medication should be withheld and
emergency management initiated.
Question 8. Which symptom is most suggestive of myocardial ischemia?
A. Crushing substernal chest pressure
B. Increased urinary frequency
C. Bilateral ear pain
D. Sudden ankle itching
Correct Answer: A. Crushing substernal chest pressure
Explanation: Myocardial ischemia commonly presents as pressure, squeezing, heaviness, or
discomfort in the chest, sometimes radiating to the arm, jaw, neck, shoulder, or back.
Question 9. A client experiencing an acute myocardial infarction is prescribed aspirin. What
is the primary therapeutic purpose?
A. Increase platelet aggregation
B. Reduce platelet aggregation
C. Increase blood glucose
D. Promote sodium retention
Correct Answer: B. Reduce platelet aggregation
Explanation: Aspirin inhibits platelet aggregation and helps reduce further thrombus
formation during acute coronary syndromes.
Question 10. Which finding is most concerning in a client with acute chest pain?
A. Pain rated 2/10 after walking
B. New ST-segment changes on ECG
C. Heart rate of 72/min
D. Respiratory rate of 16/min
Correct Answer: B. New ST-segment changes on ECG
Explanation: New ischemic ECG changes can indicate acute myocardial ischemia or
infarction and require prompt evaluation and intervention.
Question 11. A client prescribed sublingual nitroglycerin should be taught to:
