Question 4.4. An older adult female patient has presented with a new onset of shortness of
breath, and the patient's nurse practitioner has ordered measurement of her BNP levels along
with other diagnostic tests. What is the most accurate rationale for the nurse practitioner's
choice of blood work? (Points : 3)
BNP is released as a compensatory mechanism during heart failure and measuring it can help
differentiate the patient's dyspnea from a respiratory pathology.
BNP is an indirect indicator of the effectiveness of the RAA system in compensating for heart
failure.
BNP levels correlate with the patient's risk of developing cognitive deficits secondary to heart
failure and consequent brain hypoxia.
BNP becomes elevated in cases of cardiac asthma, Cheyne-Stokes respirations, and acute
pulmonary edema, and measurement can gauge the severity of pulmonary effects.
