A nurse is caring for a client who is experiencing uterine atony immediately following delivery. The client fails to respond to oxytocin administration. The nurse should anticipate the use of which of the following medications?

Choice A rationale:

The nurse should not tell the client that she cannot have an amniocentesis until she is at least 35 years of age. Age is not the primary factor for determining the eligibility for an amniocentesis. Amniocentesis is typically performed when there is a medical indication, such as advanced maternal age, abnormal prenatal screening, or a family history of genetic disorders.

Choice B rationale:

The nurse should not schedule the amniocentesis for later today without further clarification from the provider. Scheduling medical procedures without the provider's approval is not within the nurse's scope of practice and could lead to potential risks.

Choice C rationale:

This is the correct answer. The nurse should explain to the client that amniocentesis is a procedure used to determine if the baby has genetic or congenital disorders. It involves the extraction of a small amount of amniotic fluid to analyze the fetal cells for genetic abnormalities.

Choice D rationale:

The nurse should not tell the client that her provider will schedule a chorionic villus sampling (CVS) to determine the sex of the baby. CVS is another prenatal diagnostic test, but its primary purpose is to detect genetic disorders early in pregnancy, not to determine the baby's sex.

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.
