A nurse is reviewing the BUN and creatinine levels of an older adult patient with chronic kidney disease. The nurse should anticipate which of the following findings?
BUN 8 mg/dL and creatinine 0.7 mg/dL
BUN 45 mg/dL and creatinine 8 mg/dL
BUN 23 mg/dL and creatinine 1.0 mg/dL
BUN 10 mg/dL and creatinine 0.3 mg/dL
The Correct Answer is B
Choice A reason:
A BUN level of 8 mg/dL and a creatinine level of 0.7 mg/dL are within normal ranges for a healthy individual without kidney disease. In chronic kidney disease (CKD), we would expect these values to be elevated due to the kidneys' reduced ability to filter waste products from the blood.
Choice B reason:
A BUN level of 45 mg/dL and a creatinine level of 8 mg/dL are significantly higher than the normal range, which is consistent with impaired kidney function seen in CKD. These elevated levels indicate that the kidneys are not effectively filtering urea and creatinine from the blood, leading to their accumulation.
Choice C reason:
A BUN level of 23 mg/dL and a creatinine level of 1.0 mg/dL could be seen in the early stages of CKD. While the creatinine level is within the normal range, the BUN level is slightly elevated, which may suggest a decline in kidney function.
Choice D reason:
A BUN level of 10 mg/dL and a creatinine level of 0.3 mg/dL are both below the normal range. This is an unlikely finding for a patient with CKD, as kidney impairment typically leads to increased levels of these substances in the blood.

Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A reason:
Temperature is a critical parameter to assess because a significant difference in temperature between the affected and unaffected extremity can indicate compromised blood flow or infection.
Choice B reason:
Ecchymosis, or bruising, can indicate underlying bleeding or trauma to the tissues, which may affect neurovascular status.
Choice C reason:
Color changes, such as pallor or cyanosis, can signal poor circulation or oxygenation in the affected extremity.
Choice D reason:
Sensation is an essential aspect of neurovascular assessment. Altered or absent sensation can indicate nerve damage or compression.
Choice E reason:
Skin integrity is important to monitor for any signs of breakdown, which could lead to infection or further complications.
Correct Answer is C
Explanation
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.
