A nurse is caring for a child who has an exacerbation of cystic fibrosis. Which of the following laboratory findings should the nurse report to the provider immediately?

D. This is the correct action to take. A neurovascular check involves assessing the circulation, sensation, and movement in the affected limb. This check helps monitor for complications such as impaired circulation, nerve damage, or compartment syndrome, which can occur after the application of a plaster cast. Regular neurovascular checks are essential for early detection of any issues and appropriate intervention if necessary.

A. Using a hair dryer on a hot setting can cause burns to the skin under the cast. It can also cause the cast material to heat up and potentially cause discomfort or injury to the patient.

B. It's essential to follow the healthcare provider's instructions regarding weight-bearing restrictions, but completely discouraging ambulation can lead to complications such as muscle atrophy, decreased circulation, and increased risk of blood clots.

C. Keeping the client's leg in a dependent position means positioning it lower than the heart. This can increase swelling and exacerbate pain, potentially leading to complications such as compartment syndrome.

B. The most serious complication associated with skeletal traction is osteomyelitis, an infection that involves the bone. This condition can occur when organisms gain access to the bone either systemically or through the openings created by the metal pins or wires used in the traction.

A. Increased blood pressure can occur for various reasons but it is not the most serious complication associated with skeletal traction.

C. A decrease in urine output could indicate systemic infection which is a late feature of osteomyelitis and therefore, not the earliest to monitor.

D. Changes in appetite can occur in response to pain or stress but they are not typically the most serious complication associated with skeletal traction.
