A nurse is caring for a newborn whose mother was taking methadone during her pregnancy.

Which of the following findings indicates the newborn is experiencing withdrawal?

Hyperthermia is a condition in which the body temperature is abnormally high, usually due to exposure to heat, infection, or certain medications.

Hyperthermia can cause neurological complications, such as seizures, confusion, or coma. Therefore, the nurse should initiate seizure precautions for an adolescent who has hyperthermia to prevent injury and protect the airway.

Choice A is wrong because covering the adolescent with a thermal blanket would increase the body temperature and worsen hyperthermia. The nurse should remove excess clothing and use cooling measures, such as fans, ice packs, or cool fluids.

Choice B is wrong because submerging the adolescent’s feet in ice water would cause vasoconstriction and shivering, which would reduce heat loss and increase heat production. The nurse should avoid using extreme cold or ice water to cool the body.

Choice D is wrong because administering oral acetaminophen would not be effective for hyperthermia caused by non-infectious factors, such as heat exposure or medications.

Acetaminophen lowers the body temperature by reducing the hypothalamic set point, which is not altered in hyperthermia. Additionally, oral medications may be difficult to swallow or absorb in a hyperthermic patient.

Normal body temperature ranges from 36.5°C to 37.5°C (97.7°F to 99.5°F). Hyperthermia is defined as a body temperature above 38.5°C (101.3°F).

The correct answer is choice B, bradypnea. Bradypnea is abnormally slow breathing, which can be a sign of life-threatening respiratory depression caused by morphine. Respiratory depression is the most serious adverse effect of morphine and can lead to coma and death if not treated promptly. Therefore, the nurse should monitor the child’s respiratory rate and oxygen saturation closely and be prepared to administer naloxone, an opioid antagonist, if needed.

Choice A, euphoria, is wrong because euphoria is a feeling of intense happiness or well-being that is a common side effect of morphine.

Euphoria is not a priority finding and does not indicate a serious complication of morphine.

Choice C, constipation, is wrong because constipation is a common and chronic side effect of morphine that affects the gastrointestinal system.

Constipation can cause discomfort and complications such as bowel obstruction, but it is not a priority finding compared to respiratory depression.

Choice D, sedation, is wrong because sedation is another common side effect of morphine that affects the central nervous system.

Sedation can impair the child’s level of consciousness and ability to respond to stimuli, but it is not as urgent as respiratory depression.
