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:
Testicular torsion is a condition where the spermatic cord becomes twisted, cutting off the blood supply to the testicle. It is not a typical complication following a prostatectomy. Testicular torsion is generally an acute condition that affects younger males and is unrelated to prostate surgery.
Choice B reason:
Erectile dysfunction (ED) is a common complication after prostatectomy. The surgery can damage the nerves and blood vessels that control erections, leading to ED. While nerve-sparing techniques aim to reduce this risk, some degree of erectile dysfunction is still possible after the procedure.
Choice C reason:
Cystitis, which is inflammation of the bladder, can occur after a prostatectomy due to the use of a catheter or as a result of the surgery itself. However, it is not as common or as significant a long-term complication as erectile dysfunction.
Choice D reason:
Paralytic ileus, a temporary cessation of bowel movements, can occur after any abdominal surgery due to the manipulation of the intestines or as a side effect of anesthesia. While it can be a complication of prostatectomy, it is typically resolved within a few days to weeks after surgery.
Correct Answer is A
Explanation
Choice A reason:
Phenytoin is an antiepileptic drug that can be used to treat and prevent seizures. Headache and restlessness could be signs of neurological irritation or an impending seizure, which phenytoin can help to manage. It is important to monitor the client's neurological status closely following hemodialysis, as changes in electrolyte balance can affect neuronal activity.
Choice B reason:
Decreased blood pressure and rapid pulse are not typical indications for administering phenytoin. These symptoms could indicate hypovolemia or other cardiovascular issues that may occur after hemodialysis, which would require different interventions.
Choice C reason:
Muscle cramps and chest heaviness are not indications for phenytoin administration. Muscle cramps can be a common side effect of hemodialysis due to electrolyte shifts, and chest heaviness may indicate cardiovascular strain or other complications.
Choice D reason:
Pain and tingling at the access site are typically related to the vascular access itself and are not treated with phenytoin. These symptoms may require assessment for potential complications such as infection or thrombosis at the access site.
