A nurse is reinforcing teaching about preventing mastitis with a client who is breastfeeding. Which of the following instructions should the nurse include?

(A) "You will be prescribed methadone":
Methadone maintenance therapy is a commonly used treatment for opioid use disorder in pregnant women. Methadone helps to manage withdrawal symptoms, reduce cravings, and stabilize the individual, promoting healthier outcomes for both the mother and the baby.

(B) "You will be prescribed aripiprazole":
Aripiprazole is not typically prescribed for opioid use disorder. It is an antipsychotic medication used to treat conditions such as schizophrenia, bipolar disorder, and depression, but it is not indicated for opioid dependence or withdrawal.

(C) "You will be prescribed naloxone":
Naloxone is an opioid antagonist used to reverse opioid overdose. While it is crucial to have naloxone readily available for individuals with opioid use disorder to prevent overdose deaths, it is not a primary treatment for opioid use disorder during pregnancy.

(D) "You will be prescribed diazepam":
Diazepam is a benzodiazepine medication primarily used for anxiety, muscle spasms, and seizures. It is not indicated for the treatment of opioid use disorder during pregnancy. In fact, benzodiazepines like diazepam should be used with caution during pregnancy due to the risk of birth defects and neonatal withdrawal symptoms.

(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.
