A nurse is assessing a 3-month-old infant whose parents report starting cow's milk feedings 1 week ago. Which of the following actions should the nurse take?

Rationale for Correct Choices:

• Pain medication: Pain control is a primary concern in fracture management, especially in pediatric clients. This child reports a pain score of 4/10, indicating discomfort. Administering pain medication will reduce suffering and help prevent complications such as anxiety or guarding, which may impair healing.
• Limb immobilization: Immobilization stabilizes the fracture site and prevents further injury to soft tissues or neurovascular structures. With a nondisplaced fracture of both radius and ulna, the nurse should expect a splint or cast order to limit movement and aid in bone alignment and healing.

Rationale for Incorrect Choices:

• Bed rest: Bed rest is not required for isolated upper limb fractures, particularly when the child is developmentally appropriate, alert, and ambulatory. Encouraging mobility is important to reduce the risk of complications like deconditioning or thromboembolism.
• Surgical consultation: A nondisplaced fracture typically does not require surgical intervention unless complications develop. Surgical consultation is more often necessary for open, displaced, or unstable fractures that require reduction or fixation.
• Antibiotics: There are no signs of systemic or localized infection. The child has a superficial knee abrasion but no open fracture or wound that would necessitate prophylactic antibiotics. Therefore, antibiotic use is not indicated in this situation.

Rationale:

A. Prolonged QT interval: This is not a typical sign of morphine toxicity. QT prolongation is more commonly associated with certain antipsychotics, antiarrhythmics, or methadone, not opioids like morphine.

B. Fluid retention: Morphine does not typically cause fluid retention. While it may contribute to urinary retention, generalized fluid accumulation is not characteristic of opioid toxicity and may point to other causes like heart or renal failure.

C. Bradypnea: Respiratory depression, including bradypnea, is the hallmark sign of opioid toxicity. Morphine suppresses the brainstem’s respiratory centers, reducing respiratory rate and depth, which can become life-threatening without intervention.

D. Hyperactive deep tendon reflexes: Opioids tend to cause central nervous system depression, which would more likely lead to diminished reflexes. Hyperactive reflexes are not associated with morphine toxicity and may suggest a different neurological issue.
