A nurse in an ambulatory surgery center is providing discharge teaching to a client who had a dilation and curettage (D&C) following a spontaneous miscarriage.
Which of the following should be included in the teaching?

Choice A rationale

The ventrogluteal muscle, located in the hip, is a safe site for intramuscular injections in adults and children older than seven months due to its distance from major nerves and blood vessels. However, the vastus lateralis muscle in the thigh is the preferred site for IM injections in newborns and infants due to its well-developed muscle mass and accessibility.

Choice B rationale

The deltoid muscle, located in the upper arm, is small and not well-developed in newborns, making it an unsuitable site for intramuscular injections. There is also a risk of injury to the brachial nerve and blood vessels in this area in neonates.

Choice C rationale

The dorsogluteal muscle, located in the buttocks, is no longer the recommended site for intramuscular injections in infants and young children due to the proximity of the sciatic nerve and major blood vessels, increasing the risk of nerve damage.

Choice D rationale

The vastus lateralis muscle, located on the anterolateral aspect of the thigh, is the recommended site for intramuscular injections in newborns. It is a large, well-developed muscle that is easily accessible and away from major nerves and blood vessels, making it a safe and effective site for administering vitamin K to prevent hemorrhagic disease of the newborn.

Rationales for Each Condition

Neonatal Abstinence Syndrome (NAS)

1. Temperature: Infants experiencing NAS often have difficulty regulating body temperature due to autonomic instability. While the newborn's temperature of 36.6°C (97.9°F) is within normal range, the use of a radiant warmer suggests challenges in maintaining thermoregulation, which is characteristic of NAS.
2. Jitteriness: Jitteriness is observed in both hypoglycemia and NAS. In NAS, it is caused by neurological excitability due to opioid withdrawal, leading to tremors and hypertonia, which improve with soothing measures such as swaddling.
3. Skin Color: Mottling is a frequent sign in neonates experiencing opioid withdrawal due to autonomic dysregulation. The absence of cyanosis or jaundice indicates that the mottling is due to withdrawal rather than an underlying pathology.
4. GI Assessment: Loose stools and hyperactive bowel sounds are typical signs of NAS, caused by increased gastrointestinal motility due to withdrawal from opioids.

Hypoglycemia

1. Jitteriness: Hypoglycemia is characterized by neuromuscular instability, leading to jitteriness. However, in this case, the newborn’s blood glucose level of 45 mg/dL is within acceptable neonatal range, making NAS a more likely explanation.
2. Temperature, Skin Color, and GI Assessment: Hypoglycemia does not typically cause mottled skin or loose stools, making these findings more consistent with NAS.
