A nurse is caring for a client who is experiencing severe pain during active labor. Which of the following medications should the nurse plan to administer and document in the client's medical record?

Choice A rationale Hydrocodone is an opioid analgesic, but it is typically used for moderate to severe pain and is not commonly administered as a primary agent for severe active labor pain due to its slower onset and potential for more pronounced maternal and neonatal respiratory depression compared to other rapid-acting opioids. Choice B rationale Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) primarily used for mild to moderate pain and inflammation. It is generally not effective enough for severe labor pain and is contraindicated in late pregnancy due to potential adverse effects on fetal circulation, such as premature closure of the ductus arteriosus. Choice C rationale Naloxone hydrochloride is an opioid antagonist used to reverse opioid-induced respiratory depression. Administering naloxone during active labor would reverse the effects of any pain medication given, exacerbating the client's pain and potentially precipitating opioid withdrawal symptoms, thus it is not an appropriate pain management strategy. Choice D rationale Fentanyl citrate is a potent, rapid-acting synthetic opioid analgesic commonly used for severe pain during active labor. Its quick onset and short duration of action make it suitable for intermittent administration, allowing for effective pain relief with a lower risk of prolonged neonatal respiratory depression compared to longer-acting opioids.
