A nurse is assessing the reflexes of a term newborn. After placing the newborn in the supine position, which of the following methods should the nurse use to elicit the Moro reflex?

Choice A rationale:

Blood pressure of 136/88 mm Hg should be monitored, but it is not a finding that the nurse needs to urgently report to the provider following the administration of butorphanol. The blood pressure reading is slightly elevated but might be attributed to pain or anxiety during labor.

Choice B rationale:

Moderate fetal heart rate variability is a reassuring sign of fetal well-being and is an expected finding during labor. It does not require immediate reporting to the provider.

Choice C rationale:

Respiratory rate of 100/min is significantly increased and should be reported to the provider following the administration of butorphanol. Respiratory depression is a potential side effect of opioids like butorphanol, and a respiratory rate of 100/min raises concern for potential respiratory compromise.

Choice D rationale:

Urinary output of 120 mL in 2 hours is an acceptable finding during labor and does not require immediate reporting to the provider. Adequate urinary output varies, but generally, 30 mL/hour is considered acceptable during labor.

The correct answer is choice A, administer broad-spectrum antibiotics.

Choice A rationale:

Administering broad-spectrum antibiotics is crucial for a newborn with a myelomeningocele that is leaking cerebrospinal fluid to prevent infection. The leaking of cerebrospinal fluid can increase the risk of meningitis, which is an infection of the membranes covering the brain and spinal cord. Broad-spectrum antibiotics are used as a prophylactic measure to reduce this risk.

Choice B rationale:

Monitoring the rectal temperature every 4 hours is important for detecting fever, which could indicate infection. However, it is not the most immediate action required for a newborn with a leaking myelomeningocele. The priority is to prevent infection through the administration of antibiotics.

Choice C rationale:

Cleansing the site with povidone-iodine is not recommended for a myelomeningocele because it can be toxic to the exposed neural tissue. Instead, the area should be covered with a sterile saline dressing to protect the site and prevent drying and further damage to the neural tissue.

Choice D rationale:

While surgical closure is necessary for a newborn with myelomeningocele, it is typically performed within 24 to 48 hours after birth, not after 72 hours. Early closure is essential to reduce the risk of infection and further damage to the exposed spinal cord and nerves.
