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 levelsalong 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 heartfailure 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 acutepulmonary edema, and measurement can gauge the severity of pulmonary effects.Question 5.5. A patient in the intensive care unit has a blood pressure of 87/39 and has warm, flushed skin accompanying his sudden decline in level of consciousness.
