TOPIC 1: CHRONIC HEART FAILURE
7 Questions • 9.1% of Exam • Explores physiological changes and clinical manifestations associated with chronic heart failure.
QUESTION 1
A client with chronic heart failure exhibits a left ventricular end-diastolic volume
increase from 120 mL to 180 mL, while stroke volume rises from 55 mL to 70 mL. Which
physiologic principle best explains this change?
[A] Starling's law of the heart
[B] Bernoulli's principle
[C] Frank-Frankel hypothesis
[D] Guyton's renal compensation model
Correct Answer: Starling's law of the heart.
Rationale: Starling's law states that increased ventricular filling (preload) leads to a proportionate increase in stroke volume
due to optimal sarcomere length, which is reflected in the observed data.
QUESTION 2
A 68-year-old male with chronic heart failure presents with dyspnea on exertion and
peripheral edema. Which alteration in the Frank-Starling relationship best explains the
reduced cardiac output in this patient?
[A] Increased end-diastolic volume with a leftward shift of the curve
[B] Decreased end-diastolic volume with a rightward shift of the curve
[C] Increased end-diastolic volume with a rightward shift of the curve
[D] Decreased end-diastolic volume with a leftward shift of the curve
Correct Answer: Increased end-diastolic volume with a rightward shift of the curve.
Rationale: In chronic heart failure, ventricular remodeling leads to increased end-diastolic volume. The Frank-Starling curve
shifts rightward, indicating that for any given preload, stroke volume is lower, which accounts for reduced cardiac output
despite elevated filling pressures.

QUESTION 3
During acute decompensated heart failure, systemic vascular resistance is markedly
increased, raising afterload. According to systems principles, which compensatory
mechanism most directly attempts to preserve stroke volume under these conditions?
[A] Enhanced sympathetic tone that augments myocardial contractility
[B] Activation of the renin-angiotensin-aldosterone system producing venoconstriction
[C] The Frank-Starling mechanism increasing end-diastolic volume
[D] Peripheral vasodilation mediated by nitric oxide release
Correct Answer: The Frank-Starling mechanism increasing end-diastolic volume.
Rationale: When afterload rises, the heart initially relies on the Frank-Starling mechanism: increased ventricular filling
(higher end-diastolic volume) stretches myocardial fibers, which enhances stroke volume despite the elevated resistance.
This intrinsic, length-tension relationship is a primary systems-level compensatory response.

QUESTION 4
A 70-kg adult requires an initial loading dose of digoxin of 0.5 µg/kg. What is the correct
loading dose in milligrams?
[A] 0.035 mg
[B] 0.05 mg
[C] 0.35 mg
[D] 0.5 mg
Correct Answer: 0.035 Mg.
Rationale: 0.5 Μg/kg × 70 kg = 35 µg. Converting micrograms to milligrams (1 mg = 1000 µg) gives 35 µg ÷ 1000 = 0.035
mg.
