1. Left Heart Failure — Pulmonary Congestion
Stem: A 72-year-old reports worsening shortness of breath
when lying flat and wakes up gasping at night. On
assessment, lung sounds are crackles bilaterally, oxygen
saturation is 89%, and the client has pink frothy sputum. The
nurse suspects a left-sided pump problem rather than a
primary lung disorder.
,Options:
A. Left ventricular failure causing pulmonary venous
congestion
B. Right ventricular failure causing systemic venous pooling
C. Aortic regurgitation causing low diastolic pressure
D. Pericardial inflammation causing friction rub
Correct Answer: A
Rationales:
Correct Answer: Left ventricular failure raises pressure in the
left atrium and pulmonary veins, forcing fluid into the lungs.
That creates crackles, orthopnea, and pulmonary edema,
which are classic left-sided heart failure findings.
A. Correct.
B. Right heart failure primarily causes peripheral edema,
JVD, and hepatomegaly, not early pulmonary crackles.
C. Aortic regurgitation can eventually cause heart failure, but
the immediate pattern here is pulmonary congestion from
left-sided failure.
D. Pericarditis causes chest pain and a friction rub, not pink
frothy sputum and pulmonary edema.
Teaching Point: Left heart failure backs blood into the lungs
first.

Failure.
,2. Right Heart Failure — Systemic Venous Congestion
Stem: A client with chronic heart failure presents with ankle
edema, abdominal swelling, and a distended neck vein. The
client also reports feeling bloated after meals and notes that
shoes no longer fit by evening. The nurse links these findings
to impaired forward flow from the right side of the heart.
Options:
A. Right ventricular failure causing systemic venous
congestion
B. Left ventricular failure causing pulmonary edema
C. Mitral stenosis causing reduced coronary perfusion
D. Bradycardia causing decreased oxygen saturation
Correct Answer: A
Rationales:
Correct Answer: Right ventricular failure causes blood to
back up into the systemic venous circulation. This leads to
jugular venous distension, peripheral edema, ascites, and
hepatic congestion.
A. Correct.
B. Left heart failure mainly causes dyspnea, orthopnea, and
lung crackles.
C. Mitral stenosis affects left atrial emptying and pulmonary
pressures, not primary systemic edema.
D. Bradycardia may reduce cardiac output, but it does not
directly explain venous congestion findings.
, Teaching Point: Right heart failure shows up as fluid backed
up in the body.

Failure.
3. Preload and Afterload — HF Medication Effect
Stem: A client with systolic heart failure has a blood pressure
of 154/94 mm Hg and reports fatigue with minimal exertion.
The provider starts an ACE inhibitor. The nurse understands
that the medication is helping the heart by making ejection
easier.
Options:
A. Decreasing afterload by reducing systemic vascular
resistance
B. Increasing preload to improve ventricular filling
C. Increasing heart rate to improve myocardial oxygen
demand
D. Causing blood to pool in the lungs to increase output
Correct Answer: A
Rationales:
Correct Answer: ACE inhibitors reduce angiotensin II, which
lowers systemic vascular resistance and afterload. A lower
afterload allows the failing left ventricle to eject blood more
effectively.
A. Correct.
