A nurse is providing teaching to a client who has a prescription for heat therapy for the treatment of cellulitis of the right lower leg. Which of the following client statements indicates an understanding of the teaching?

Choice A reason:
Urine-specific gravity measures the concentration of urine compared to water. It can indicate various conditions affecting the kidneys, but it does not provide a direct measure of renal function. It can be affected by hydration status and does not specifically reflect kidney damage or disease.

Choice B reason:
Blood urea nitrogen (BUN) levels can indicate kidney health; however, BUN can also be influenced by factors such as protein intake, hydration, and liver function. Therefore, while it is a useful test, it is not the most specific indicator of renal function in isolation.

Choice C reason:
Serum sodium levels are important for assessing electrolyte balance and can be affected by kidney function. However, changes in serum sodium are not specific to kidney function alone and can result from a variety of conditions.

Choice D reason:
Serum creatinine is a waste product from the normal breakdown of muscle tissue. As the kidneys are responsible for filtering out creatinine, its level in the blood is a good indication of kidney function. Elevated levels of serum creatinine may indicate impaired kidney function or kidney disease. In the context of SLE, where kidney involvement is common, serum creatinine is a crucial marker for monitoring renal function.

Choice A reason:

Skin traction is indeed less restrictive than skeletal traction, allowing for more mobility. It is applied using bandages or adhesive material to the skin, which can be removed or adjusted more easily than the pins or screws used in skeletal traction. This type of traction is typically used for short-term treatment before surgery or when the injury is less severe.

Choice B reason:

Discomfort levels can vary depending on the individual and the specific circumstances of the traction. However, skin traction is generally considered to be less painful than skeletal traction because it is less invasive and applies less force. Skeletal traction, which involves the insertion of pins or wires directly into the bone, is likely to cause more discomfort due to the invasive nature of the procedure.

Choice C reason:

Skeletal traction is more appropriate for reducing fractures, especially in cases where a greater force is needed to align the bones. It involves the surgical insertion of pins or wires directly into the bone, allowing for a stronger and more stable pull that is necessary for the realignment of complex fractures.

Choice D reason:

Skeletal traction carries a higher risk of infection compared to skin traction because it is more invasive. The insertion of pins or wires into the bone creates a potential entry point for bacteria, which can lead to infection at the site of insertion.
