A woman who delivered a normal newborn 24 hours ago reports, "I seem to be urinating every hour or so. Is that OK?" Which action should the practical nurse (PN) implement?

Catheterize the client for residual urine volume.

Measure the next voiding, then palpate the client's bladder.

Evaluate for normal involution, then massage the fundus.

Obtain a specimen for urine culture and sensitivity.
