Question

What is considered a normal and abnormal postvoid residual volume?

a) Normal: 50-100 mL; Abnormal: >200 mL
b) Normal: <50 mL; Abnormal: >100 mL
c) Normal: 100-150 mL; Abnormal: >300 mL
d) Normal: 200-250 mL; Abnormal: >500 mL

Answer 1

The normal postvoid residual volume is <50 mL, while an abnormal postvoid residual volume is >100 mL.

Step-by-step explanation:

The normal and abnormal postvoid residual volume can be defined as follows:

• Normal postvoid residual volume: <50 mL
• Abnormal postvoid residual volume: >100 mL

The postvoid residual volume is the amount of urine that remains in the bladder after voiding. A normal postvoid residual volume indicates that the bladder is effectively emptying, while an abnormal postvoid residual volume may suggest urinary retention or bladder dysfunction.
