66. A 72-year-old male patient is admitted to the emergency department with shortness of breath, fatigue, and bilateral lower extremity edema. His blood pressure is 140/90 mmHg, heart rate is 98 bpm, respiratory rate is 22 breaths per minute, and oxygen saturation is 94% on room air. Laboratory results reveal a pro-BNP level of 2,485 pg/mL.
Which of the following interventions should the nurse anticipate for this patient?
Correct Answer: A. Administer IV furosemide as prescribed
Rationale:
-An elevated pro-BNP (>450 pg/mL in patients over 50) indicates heart failure, as BNP is released in response to ventricular stretching due to fluid overload. Diuretics like furosemide help reduce fluid retention, relieve pulmonary congestion, and improve symptoms.
B is incorrect because increasing fluid intake can worsen fluid overload in heart failure.
C is incorrect because placing the patient in a supine position can exacerbate pulmonary congestion and worsen breathing difficulty. Elevating the head of the bed is preferred.
D is incorrect because fluid overload is a concern, and IV fluid boluses are contraindicated in decompensated heart failure unless there is clear evidence of hypovolemia.
NCLEX TIPS:
BNP (B-type Natriuretic Peptide)
Normal Range: Less than 100 pg/mL
Clinical Indications:
BNP levels >100 pg/mL may suggest heart failure, especially if consistent with clinical symptoms such as dyspnea, edema, or fatigue.
-Higher levels typically correlate with worse heart failure severity.
NT-proBNP (N-terminal pro b-type Natriuretic Peptide)
Normal Ranges:
Age < 75 years: Less than 125 pg/mL
Age ≥ 75 years: Less than 450 pg/mL
Clinical Indications:
NT-proBNP levels >900 pg/mL (in patients under 50, some guidelines use >450 pg/mL) may indicate acute or decompensated heart failure.
Like BNP, values increase with worsening heart function and can be influenced by age, renal function, and obesity.
