When assessing the patient with high-output heart failure, the nurse is most likely to find:
A) vasoconstriction and hypotension.
B) vasoconstriction and hypertension.
C) vasodilation and hypotension.
D) vasodilation and hypertension.
C) vasodilation and hypotension.
Explanation: A) In high-output heart failure, heart failure syndrome exists even though the heart is pumping a large amount of blood, more than 8 liters per minute. This condition is usually seen when there is vasodilation of the systemic blood vessels and blood pressure is decreased. When the blood pressure decreases, the sympathetic nervous system is activated, and the neurohormonal effects of heart failure emerge. Therefore, even though the CO is elevated, the heart failure syndrome exists.
