A patient admitted for asthma is weak and tired. Which patient position should the nurse use for patient performance of a peak expiratory flow rate (PEFR)?
a. Standing
b. Side lying
c. High-Fowler's
d. Reclining in chair
C
The nurse uses high-Fowler's position to promote optimum lung expansion. Standing for patient performance of PEFR to facilitate chest expansion would be unsafe. Side lying and reclining in a chair for PEFR measurement are not ideal because these positions impair chest expansion.

The female hormones increase the client's body weight, which decreases the production of bile. 4. Females tend to take more medications than males, and medications increase cholesterol production that causes biliary stasis.
