A patient in the pediatric intensive care unit has hemodynamic monitoring. Her cardiac output is 3 L/minute. Which assessment finding is consistent with this reading?
A. Capillary refill: 2 seconds
B. Temperature: 103 °F (39.4 °C)
C. Urine output: 3 mL/kg/hour
D. Weak, thready pulse
ANS: D
A cardiac output of 3 L/minute is low, indicating such conditions as heart failure, hypovolemia, or increased systemic vascular resistance. A weak, thready pulse would be consistent with this reading. Capillary refill of 2 seconds is normal. An increased temperature would not be related. A urine output of 3 mL/kg/hour is more than sufficient and does not indicate low cardiac output.
