A nurse is reinforcing teaching with a client who is at 24 weeks of gestation and has opioid use disorder. Which of the following statements should the nurse make?

(a) Touch the corner of the newborn's mouth:
Touching the corner of the newborn's mouth elicits the rooting reflex, not the Babinski reflex. The rooting reflex causes the newborn to turn their head toward the touch and open their mouth, which helps with feeding.

(b) Place the newborn supine and apply pressure to the soles of the feet:
Applying pressure to the soles of the feet is not a method used to elicit the Babinski reflex. This action might influence other reflexes but not the Babinski.

(c) Stroke upward on the lateral aspect of the sole of the newborn's foot:
This is correct. The Babinski reflex is elicited by stroking upward on the lateral aspect of the sole of the newborn's foot. A positive response is the fanning and extension of the toes, which is normal in newborns.

(d) Pull the newborn up by the wrist from a supine position:
Pulling the newborn up by the wrists from a supine position is used to assess the traction response or pull-to-sit maneuver, which tests the newborn's head control and muscle tone, not the Babinski reflex.

(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.
