A nurse is assisting with the care of a school-age child who has shigella. Which of the following actions should the nurse take?

Choice A rationale:
Urine osmolality 500 mOsm/kg. Urine osmolality is a measure of urine concentration and is not a reliable indicator of infection. It reflects the kidney's ability to concentrate urine and can vary based on hydration status and other factors. An elevated urine osmolality could suggest dehydration, not necessarily infection.
Choice B rationale:
WBC 17,500/mm3. This is the correct choice. An elevated white blood cell count (WBC) is a hallmark sign of infection. The body's immune response to an infection often includes an increase in WBC count, particularly the neutrophil count. This elevation is known as leukocytosis and is a red flag for infection.
Choice C rationale:
BUN 12 mg/dL. Blood Urea Nitrogen (BUN) measures kidney function and hydration status. While an elevated BUN can indicate dehydration, it is not a specific marker for infection. BUN levels can be influenced by various factors, including diet and renal function.
Choice D rationale:
Urine specific gravity 1.014. Urine-specific gravity reflects the concentration of solutes in urine and the kidney's ability to concentrate or dilute urine. While changes in urine specific gravity can indicate dehydration or overhydration, it is not a direct indicator of infection. An infection is better detected through changes in WBC count and other clinical signs.

Choice A rationale:
Gently lift the traction weights off the floor when repositioning the client. Rationale: This choice is not recommended in the care of a client in skeletal traction. Traction weights should never be lifted off the floor as they provide the necessary counter traction to align and immobilize the fractured bone. Lifting the weights could disrupt the traction and jeopardize the healing process.
Choice B rationale:
Reduce intake of foods containing fiber while nonambulatory. Rationale: While constipation can be a concern for clients in skeletal traction due to decreased mobility, reducing fiber intake is not the appropriate intervention. Adequate fiber intake is important to promote regular bowel movements and prevent constipation. Hydration and mobility exercises are more suitable approaches to manage constipation.
Choice C rationale:
Perform passive range-of-motion exercises to the affected extremity every 2 hours. Rationale: Passive range-of-motion exercises are important to maintain joint mobility and prevent muscle atrophy in a nonambulatory client. However, performing these exercises every 2 hours might be excessive and could cause unnecessary discomfort for the client. Range-of-motion exercises are usually done every 4 to 8 hours to strike a balance between maintaining joint health and providing rest.
Choice D rationale:
Apply protective padding to the end of the pin sites. Rationale: This is the correct choice. Applying protective padding to the end of the pin sites is crucial to prevent pressure ulcers and infection. The pin sites are potential entry points for bacteria, and protecting them helps reduce the risk of infection. Padding also prevents pressure on the skin and underlying tissues, reducing the potential for pressure injuries.
