A nurse is caring for a client in the emergency department who is in active labor on December 26. The client reports their last menstrual period was around April 1. Which of the following ages is the anticipated gestational age of the fetus?

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.

Choice A rationale

Bladder distention upon palpation indicates urinary retention, not effective voiding. When the bladder remains distended, it signifies incomplete emptying, which can lead to urinary stasis and increased risk of urinary tract infections. Effective voiding requires coordinated detrusor muscle contraction and urethral sphincter relaxation, which is absent with distention.

Choice B rationale

A uterine fundus 2 cm above the umbilicus, especially in the postpartum period, suggests uterine atony and possible bladder distention. A full bladder can displace the uterus upward and to the side, preventing effective uterine contraction and involution, which is crucial for preventing postpartum hemorrhage. Normal fundal height should decrease daily.

Choice C rationale

Not feeling the urge to urinate could indicate nerve damage, overdistention with sensory nerve suppression, or a very low urine output. Normal bladder sensation is crucial for effective voiding. The absence of the urge may lead to prolonged bladder distention, increasing the risk of infection and bladder dysfunction, which hinders efficient emptying.

Choice D rationale

Urinating 30 mL/hr, while seemingly low, is a continuous output and suggests the client is able to empty their bladder, albeit slowly. Postpartum diuresis typically begins within 12 hours, with urine output of 100 to 250 mL/hr common. However, any consistent output, rather than retention, indicates some voiding effectiveness.
