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 C
Explanation
Choice A reason:
While explaining discharge instructions is an important part of patient education and ensuring safety after leaving the hospital, it is not the immediate priority. The nurse must first address any potential medical issues that could compromise the patient's health, such as circulation and nerve function in the affected limb.
Choice B reason:
Applying an ice pack to the casted leg can help reduce swelling and provide comfort to the client. This is often recommended for the first 24 to 72 hours after the cast is applied, especially if the cast is on a leg. However, this is secondary to assessing the neurovascular status of the limb.
Choice C reason:
Performing a neurovascular assessment is the priority action for the nurse. This assessment includes checking for sensation, warmth, capillary refill, pulses, and movement. It is crucial to identify any signs of compromised blood flow or nerve injury early to prevent further complications.
Choice D reason:
Providing reassurance to the client and parents is important for emotional support and can help alleviate anxiety. However, the nurse's immediate priority is to ensure the physical well-being of the client, which includes performing a neurovascular assessment to detect any urgent issues.
Correct Answer is D
Explanation
Choice A reason:
Ecchymosis, or bruising, of the surrounding skin is a common finding associated with fractures due to the trauma to blood vessels in the area. While it can indicate bleeding or injury, ecchymosis itself does not specifically indicate impaired venous return.
Choice B reason:
Acute pain is a typical symptom following a fracture and results from the injury to the bone and surrounding tissues. Pain is an expected finding and does not directly suggest an issue with venous return.
Choice C reason:
A bounding distal pulse may actually suggest increased arterial flow or could be a sign of other conditions such as high blood pressure or fever. It does not indicate impaired venous return, which is typically characterized by a lack of pulse or a very weak pulse.
Choice D reason:
Increasing edema, or swelling, in the affected arm is a sign of impaired venous return. When veins are unable to effectively return blood to the heart, fluid can accumulate in the tissues, leading to edema. In the context of a fracture, this could be due to compression or damage to the veins, which can impede blood flow and result in swelling.
