To prevent heat loss from convection in a newborn, which action by the nurse is best?

A. Nalbuphine (Nubain):Nalbuphine is an opioid agonist-antagonist, which can be used to treat moderate to severe pain. However, it is not specifically used to reverse the effects of fentanyl. Administering Nalbuphine could potentially complicate the situation by introducing another opioid into the system.

B. Naloxone (Narcan):Naloxone is an opioid antagonist that rapidly reverses the effects of opioids like fentanyl. It is the standard treatment for opioid overdose and can quickly restore normal respiration in a person whose breathing has slowed or stopped due to opioid use. This makes it the most appropriate drug to have readily available in this scenario.

C. Butorphanol (Stadol):Butorphanol is another opioid agonist-antagonist used for pain relief. Similar to Nalbuphine, it is not used to reverse opioid effects and could complicate the patient's condition by adding another opioid to the system.

D. Promethazine (Phenergan):Promethazine is an antihistamine used to treat nausea, vomiting, and allergies. It does not have any properties that would counteract the effects of fentanyl. Therefore, it would not be useful in reversing opioid-induced respiratory depression.

The correct answer is choice A, delayed respiratory depression.

Choice A reason:

Delayed respiratory depression is not one of the main nursing observations for a woman who receives epidural or intrathecal opioids. Epidural and intrathecal opioids are administered for pain relief during labor or after certain surgeries, and they act locally within the spinal cord to block pain signals. Unlike systemic opioids, which can cause respiratory depression when given in high doses, epidural and intrathecal opioids have a more limited systemic effect, reducing the risk of respiratory depression. Therefore, monitoring for delayed respiratory depression is not a primary concern in this context.

Choice B reason:

Choice B is a valid nursing observation for a woman who receives epidural or intrathecal opioids. These opioids can cause temporary paralysis or weakness in the lower extremities as a side effect of their action on the nerves in the spinal cord. Nurses need to assess the woman's ability to move her lower extremities and ensure her safety and comfort while this effect is present.

Choice C reason:

Choice C is a valid nursing observation for a woman who receives epidural or intrathecal opioids. Pruritus, which refers to itching or a sensation of itchiness, is a common side effect of opioids, including those administered via epidural or intrathecal routes. The nurse should assess the woman for any signs of pruritus and manage it appropriately if it occurs.

Choice D reason:

Choice D is a valid nursing observation for a woman who receives epidural or intrathecal opioids. Nausea and vomiting are common side effects of opioids, and they can occur after receiving these medications via epidural or intrathecal routes. The nurse should monitor the woman for any signs of nausea and vomiting and provide supportive care if needed.
