A nurse is reinforcing teaching with a client about laboratory testing during pregnancy. Which of the following statements should the nurse include in the teaching?

(A) Diuresis:
Diuresis, or increased urine production, is not a typical adverse effect of nalbuphine hydrochloride. Opioids generally do not affect urine output in the same way as diuretic medications.

(B) Fever:
Fever is not a common adverse effect of nalbuphine hydrochloride. If a client develops a fever during labor, it could indicate other underlying causes such as infection or inflammation, but it is not directly related to the administration of this medication.

(C) Diarrhea:
Diarrhea is not a typical adverse effect of nalbuphine hydrochloride. Opioid medications are more commonly associated with constipation due to their effects on gastrointestinal motility and function.

(D) Sedation:
Nalbuphine hydrochloride is an opioid analgesic used for pain relief during labor. Sedation is a common adverse effect of opioid medications, including nalbuphine. Opioids can depress the central nervous system, leading to drowsiness, sedation, and decreased level of consciousness. It's essential for the nurse to monitor the client closely for signs of sedation, especially during labor, to ensure the safety of both the mother and the baby.

(a) Offer an ice pack to the client during the first 24 hr.
Offering an ice pack is an appropriate intervention for managing perineal pain and swelling in the immediate postpartum period. Ice helps to reduce inflammation and numb the area, providing pain relief. This is a standard recommendation for managing perineal pain after vaginal delivery.

(b) Apply a corticosteroid cream to the perineal area twice daily.
Applying a corticosteroid cream is not typically recommended for perineal pain immediately after delivery. These creams are generally used for inflammatory skin conditions and not for the acute management of perineal pain and swelling after childbirth.

(c) Increase the client's fluid intake for 48 hr.
While maintaining adequate hydration is important for overall recovery, increasing fluid intake specifically does not address the client's perineal pain. This intervention would not provide immediate pain relief for the perineal area.

(d) Catheterize the client's bladder.
Catheterizing the bladder is not a standard intervention for perineal pain. It is typically done if the client has urinary retention or difficulty voiding, not for managing pain. This action would not directly alleviate the perineal pain the client is experiencing.
