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 D
Explanation
Choice A reason:
Telling a client that they will be at an increased risk of breast cancer due to fibrocystic breast changes would be incorrect. Fibrocystic breast changes are not directly linked to an increased risk of breast cancer. While the presence of complex fibrocystic changes may slightly elevate the risk, fibrocystic breasts themselves are a common and benign condition.
Choice B reason:
It is not accurate to say that the manifestations of fibrocystic breasts often get worse after menopause. In fact, fibrocystic changes are related to hormone levels, and most women experience relief from these symptoms after menopause when hormone levels decline.
Choice C reason:
Stating that menopause won't have any effect on the manifestations is also incorrect. Menopause typically leads to a decrease in hormone levels, which are associated with fibrocystic breast changes. Therefore, most women see an improvement in their symptoms after menopause.
Choice D reason:
The most appropriate response is that the manifestations usually go away after menopause. Fibrocystic breast changes are linked to hormonal fluctuations, and after menopause, when these fluctuations cease, the symptoms of fibrocystic breasts typically resolve.
Correct Answer is B
Explanation
Choice A Reason:
While performing range of motion exercises is important for maintaining joint function and preventing stiffness, it is not the first action a nurse should take. Range of motion exercises should only be performed after ensuring that there is no compromise in circulation or nerve function.
Choice B Reason:
Checking capillary refill is the correct first action. This quick test assesses the blood flow to the extremity and can indicate if there is any vascular obstruction. A delayed capillary refill time, which is more than 2 seconds, could signify compromised circulation and necessitate immediate intervention.
Choice C Reason:
Discussing cast care is important for client education and preventing complications such as skin breakdown and infection. However, it is not the first priority. The nurse should first ensure the client's physiological stability before providing education.
Choice D Reason:
Managing pain is a critical component of nursing care, especially for clients with fractures. However, the assessment of circulation takes precedence over pain management. Once it is established that there is no immediate threat to the limb's viability, pain management should be addressed promptly.
In summary, the priority for a nurse assessing a client with a cast for a fractured tibia is to check the capillary refill to ensure adequate circulation. This is followed by managing pain, performing range of motion exercises, and discussing cast care with the client.
