HEART FAILURE CLINICAL REASONING
CASE STUDY – MR. KELLY, 56 YEARS OLD.
SECTION 1: ADMISSION ASSESSMENT & HISTORY COLLECTION
Q1: Mr. Kelly, a 56-year-old male, presents to the emergency department with progressive
shortness of breath over the past 2 weeks, worsening over the last 2 days. He reports dyspnea
at rest and requires three pillows to sleep. Which additional assessment finding is most
consistent with left-sided heart failure?
A. Hepatomegaly and bilateral lower extremity pitting edema
B. Jugular venous distension and cool extremities
C. Crackles bilaterally in the lower two-thirds of lung fields and frothy pink-tinged sputum
D. Ascites and hepatic tenderness to palpation
Correct Answer: C
Rationale: Correct because crackles in the lower lung fields and frothy pink-tinged sputum are
classic manifestations of pulmonary venous congestion resulting from elevated left ventricular
end-diastolic pressure and fluid transudation into the alveoli, which are hallmark signs of left-
sided heart failure.
Q2: During the admission history, the nurse notes that Mr. Kelly has gained 8 lbs (3.6 kg) over
the past week. Which pathophysiological mechanism best explains this acute weight gain?
A. Increased metabolic rate from stress hyperglycemia causing tissue anabolism
B. Sodium and water retention secondary to neurohormonal activation of the renin-
angiotensin-aldosterone system
C. Decreased intestinal absorption due to congestive hepatopathy
D. Protein malnutrition from poor oral intake related to nausea
Correct Answer: B
Rationale: Correct because reduced left ventricular ejection fraction triggers compensatory
neurohormonal activation of the renin-angiotensin-aldosterone system and antidiuretic
hormone, promoting renal sodium and water retention and resulting in rapid fluid accumulation
and weight gain.
, Q3: Mr. Kelly admits to frequently skipping his prescribed furosemide because "it makes me
have to run to the bathroom." Which nursing response best addresses this medication
nonadherence while supporting patient education?
A. "You should take the furosemide only when your ankles swell to avoid excessive urination."
B. "Taking furosemide in the morning will minimize nighttime urination and help prevent fluid
buildup that causes your breathing difficulty."
C. "Skipping furosemide is acceptable as long as you maintain a low-sodium diet and monitor
your weight."
D. "Your doctor can switch you to a different diuretic that does not cause increased urination."
Correct Answer: B
Rationale: Correct because educating the patient to take loop diuretics in the morning aligns
with best practice to minimize nocturia while emphasizing the critical role of consistent diuresis
in preventing acute decompensated heart failure and pulmonary congestion.
Q4: The nurse auscultates an S3 gallop during the cardiac examination. Which physiological
event produces this finding?
A. Turbulent blood flow across a stenotic mitral valve during ventricular systole
B. Rapid deceleration of blood entering a noncompliant, volume-overloaded left ventricle
during early diastole
C. Closure of the pulmonic valve delayed by right ventricular volume overload
D. Regurgitant flow through an incompetent aortic valve during ventricular diastole
Correct Answer: B
Rationale: Correct because the S3 gallop is generated by the abrupt deceleration of blood
entering a stiff, noncompliant left ventricle with elevated filling pressures during early diastole,
indicating volume overload and decreased left ventricular compliance characteristic of
decompensated heart failure.
Q5: Mr. Kelly is noted to have jugular venous distension at 45 degrees, measuring 4 cm above
the sternal angle. This finding primarily reflects which hemodynamic abnormality?
A. Increased pulmonary capillary wedge pressure from left ventricular failure
B. Elevated right atrial pressure secondary to right ventricular dysfunction and systemic venous
congestion
C. Reduced systemic vascular resistance from peripheral vasodilation
D. Decreased preload from excessive diuretic therapy
