A nurse is caring for a client who has fibrocystic breasts. The client asks the nurse, "What will happen to my fibrocystic breast changes after menopause?" Which of the following statements is an appropriate response by the nurse?

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.

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.
