A nurse in a critical care unit is assessing an adult client. Which of the following findings by the nurse indicates a fluid volume deficit?
Heart rate 118/min
Central venous pressure 25 mm Hg
Blood pressure 152/90 mm Hg
Temperature 37.2° C (99° F)
The Correct Answer is A
A. A heart rate of 118/min suggests tachycardia, which is a compensatory mechanism in response to fluid volume deficit. The body increases heart rate to maintain cardiac output when fluid volume is low.
B. A central venous pressure of 25 mm Hg may indicate fluid volume overload rather than deficit. It suggests increased venous pressure, possibly due to excess fluid.
C. A blood pressure of 152/90 mm Hg is within the normal range and does not specifically indicate fluid volume deficit.
D. A temperature of 37.2°C (99°F) is within the normal range and does not specifically indicate fluid volume deficit.
