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 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.
Correct Answer is A
Explanation
Choice A reason:
Morphine is an opioid analgesic that can cause a decrease in gastrointestinal motility, leading to constipation and exacerbation of paralytic ileus, a condition where there is a cessation of peristalsis in the intestine. In the case of paralytic ileus, the intestinal contents cannot move, which can lead to bowel distention, pain, and further complications. Therefore, morphine is contraindicated in clients with paralytic ileus due to the risk of worsening the condition.
Choice B reason:
While morphine can suppress cough and provide some relief in respiratory conditions, it is not contraindicated in bronchitis pleurisy unless respiratory depression is present. However, caution is advised as morphine can cause respiratory depression and should be used carefully in patients with underlying respiratory disorders.
Choice C reason:
Morphine is often used in the management of acute myocardial infarction (MI) to relieve chest pain, reduce anxiety, and decrease the workload on the heart by lowering blood pressure and heart rate. It is not contraindicated in MI; in fact, it can be beneficial in managing the symptoms associated with MI.
Choice D reason:
Postoperative pain management following hip arthroplasty often includes opioids like morphine. Morphine is not contraindicated in this situation and can be used to control postoperative pain, provided that the patient's respiratory function is closely monitored
