The critical care nurse is caring for a patient with a central venous pressure (CVP) monitoring system. The nurse notes that the patient's CVP is increasing. Of what may this indicate?
A) Psychosocial stress
B) Hypervolemia
C) Dislodgment of the catheter
D) Hypomagnesemia
Ans: B
Feedback:
CVP is a useful hemodynamic parameter to observe when managing an unstable patient's fluid volume status. An increasing pressure may be caused by hypervolemia or by a condition, such as heart failure, that results in decreased myocardial contractility. Stress, dislodgement of the catheter, and low magnesium levels would not typically result in increased CVP.
