Which assessment does the nurse use to determine the adequacy of circulation in a client whose blood osmolarity is 250 mOsm/L?
a. Measuring urine output
b. Measuring abdominal girth
c. Monitoring fluid intake
d. Comparing radial versus apical pulses
A
The blood osmolarity is low. The client could be dehydrated (hypo-osmolar dehydration) or overhydrated with dilution of blood solute. The most sensitive noninvasive indicator of circula-tion adequacy is urine output. Measuring abdominal girth, comparing pulses, and monitoring fluid intake would not be accurate assessment techniques for this client.
