1. A nurse is assessing a patient with suspected heart failure. Which
assessment finding is most indicative of left-sided heart failure?
A. Jugular venous distention
B. Peripheral edema
C. Crackles in the lung bases
D. Hepatomegaly
CORRECT ANSWER: C. Crackles in the lung bases
Rationale: Left-sided heart failure results in pulmonary congestion
due to the inability of the left ventricle to effectively pump blood
forward. This causes blood to back up into the pulmonary
circulation, leading to increased hydrostatic pressure and fluid
leakage into the alveoli, which manifests as crackles (rales) on
,auscultation. Jugular venous distention, peripheral edema, and
hepatomegaly are signs of right-sided heart failure.
2. A patient with heart failure reports a weight gain of 3 pounds
overnight and increased shortness of breath. What is the nurse's
priority action?
A. Encourage the patient to increase oral fluid intake
B. Administer a prescribed PRN dose of potassium
C. Notify the healthcare provider immediately
D. Reassure the patient that this is expected
CORRECT ANSWER: C. Notify the healthcare provider
immediately
Rationale: Sudden weight gain of 2-3 pounds or more in 24 hours
indicates acute fluid retention and is a hallmark sign of worsening
heart failure. This requires immediate provider notification for
potential adjustment of diuretic therapy or other interventions to
prevent pulmonary edema and respiratory compromise.
3. A nurse is preparing to administer digoxin to a patient. Which
laboratory value requires the nurse to hold the medication and notify
the provider?
,A. Heart rate of 98 beats per minute
B. Serum potassium of 3.2 mEq/L
C. Blood pressure of 140/86 mmHg
D. Apical pulse of 70 beats per minute
CORRECT ANSWER: B. Serum potassium of 3.2 mEq/L
Rationale: Hypokalemia (serum potassium below 3.5 mEq/L)
significantly increases the risk of digoxin toxicity because digoxin
competes with potassium for binding sites on the sodium-
potassium ATPase pump. A potassium level of 3.2 mEq/L is
below normal and places the patient at high risk for dangerous
dysrhythmias. The nurse should hold the digoxin and notify the
provider.
4. Which patient is at greatest risk for developing cardiovascular
disease?
A. A 45-year-old male with a BMI of 24 and no family history of
heart disease
B. A 55-year-old female who exercises three times per week
C. A 60-year-old male with hypertension, diabetes, and a 30-pack-
year smoking history
, D. A 50-year-old female with controlled hyperlipidemia
CORRECT ANSWER: C. A 60-year-old male with hypertension,
diabetes, and a 30-pack-year smoking history
Rationale: This patient has multiple major modifiable risk factors
for cardiovascular disease, including hypertension, diabetes
mellitus, and tobacco use. The combination of these risk factors
has a synergistic effect that dramatically increases cardiovascular
risk. Age (60 years) and male gender are also non-modifiable risk
factors that contribute to elevated risk.
5. A nurse is caring for a patient 2 hours after a cardiac
catheterization via the left femoral artery. The nurse notes a weak
left pedal pulse. What is the priority nursing action?
A. Document the finding as expected
B. Elevate the left leg above heart level
C. Apply warm compresses to the left foot
D. Notify the healthcare provider immediately
CORRECT ANSWER: D. Notify the healthcare provider
immediately
