1. Heart Failure — Early Manifestations & Fluid Overload
Reference: Heart Failure — Symptoms and Signs of Heart
Failure
Stem: A 68-year-old client with a history of hypertension
reports waking up at night short of breath and needing two
pillows to sleep. On assessment, the nurse notes bilateral
,ankle edema, bibasilar crackles, and a weight gain of 2 kg in 3
days. Which interpretation best explains these findings?
A. Reduced cardiac output has triggered compensatory fluid
retention and pulmonary congestion
B. The client is developing hypovolemic shock from
inadequate circulating volume
C. Left ventricular failure causes decreased urine output
because the kidneys stop functioning
D. Peripheral edema occurs only when right-sided heart
failure is absent
Correct Answer: A
Rationale — Correct Answer: Left-sided heart failure reduces
effective forward flow, so the body activates neurohormonal
responses that retain sodium and water. This increases
preload and worsens pulmonary congestion, causing
orthopnea, crackles, and rapid weight gain.
Rationale — Incorrect Options:
B. The findings indicate volume overload, not hypovolemia.
C. The kidneys usually remain functional but respond to low
perfusion by retaining fluid.
D. Peripheral edema is common in right-sided failure and can
also appear with biventricular failure.
Teaching Point: Heart failure often causes fluid retention
that worsens both pulmonary and peripheral congestion.

2. Left Heart Failure — Pulmonary Congestion
Reference: Left Heart Failure
Stem: A client with worsening left ventricular failure is
increasingly dyspneic and reports pink, frothy sputum. The
nurse auscultates crackles in both lung bases and notes an
oxygen saturation of 88%. Which mechanism most directly
explains these findings?
A. Blood backs up into the pulmonary circulation, increasing
hydrostatic pressure in lung capillaries
B. Systemic venous pressure rises, causing fluid to leak into
the alveoli first
C. Right ventricular contraction becomes stronger, forcing
fluid into the lungs
D. Pulmonary arteries constrict to improve oxygenation and
reduce edema
Correct Answer: A
Rationale — Correct Answer: In left heart failure, blood
cannot move forward efficiently, so pressure rises in the
pulmonary veins and capillaries. Fluid then shifts into lung
tissue and alveoli, causing crackles, hypoxemia, and frothy
sputum.
, Rationale — Incorrect Options:
B. Systemic venous congestion primarily causes peripheral
edema, not pulmonary edema.
C. Stronger right ventricular contraction does not cause
alveolar flooding.
D. Pulmonary vasoconstriction does not relieve pulmonary
edema and may worsen afterload.
Teaching Point: Left-sided failure causes pulmonary
congestion before systemic edema becomes prominent.

3. Right Heart Failure — Systemic Venous Congestion
Reference: Right Heart Failure
Stem: A client with chronic lung disease now has a distended
neck vein, enlarged liver, and dependent edema. The nurse
notes the client’s abdomen feels full and the shoes no longer
fit. Which finding is most consistent with right-sided heart
failure?
A. Pulmonary edema with severe crackles
B. Peripheral edema and jugular venous distention
C. Hyperactive bowel sounds and diarrhea
D. Bounding pulses and low central venous pressure
Correct Answer: B
