The nurse is caring for a patient receiving a continuous norepinephrine (Levophed) IV infusion. Which patient assessment finding indicates that the infusion rate may need to be adjusted?
a. Heart rate is 58 beats/minute.
b. Mean arterial pressure (MAP) is 56 mm Hg.
c. Systemic vascular resistance (SVR) is elevated.
d. Pulmonary artery wedge pressure (PAWP) is low.
ANS: C
Vasoconstrictors such as norepinephrine (Levophed) will increase SVR, and this will increase the work of the heart and decrease peripheral perfusion. The infusion rate may need to be decreased. Bradycardia, hypotension (MAP of 56 mm Hg), and low PAWP are not associated with norepinephrine infusion.
