A male client attends a community support program for mentally impaired and chemical-abusing clients. The client tells the practical nurse (PN) that his drugs of choice are cocaine and heroin. What is the greatest health risk for this client?

This is the correct answer because BUN and creatinine are the most important laboratory values to monitor for nephrotoxicity, which is the damage or injury to the kidneys caused by certain drugs or chemicals.
Nephrotoxicity can impair the kidneys' ability to filter waste products from the blood, resulting in elevated levels of BUN and creatinine. The normal range for BUN is 7 to 20 mg/dL, and for creatinine is 0.6 to 1.2 mg/dL. The practical nurse (PN) should review these values before administering an antibiotic that can cause nephrotoxicity, such as aminoglycosides, cephalosporins, vancomycin, or sulfonamides. The PN should also monitor the client for signs and symptoms of nephrotoxicity, such as decreased urine output, edema, hypertension, fatigue, nausea, and confusion.

This statement suggests that the client has found sources of emotional support and is relying on them to cope with the challenges posed by his prognosis. Acceptance of a prognosis often involves coming to terms with the reality of the situation and finding ways to manage the emotional and practical aspects of it. By acknowledging the support he has received from his faith and family, the client demonstrates a willingness to lean on these resources for strength and comfort.
The other statements do not necessarily reflect acceptance of the prognosis:

A. "I think I had this disease for a long time, but the doctor did not find it." This statement implies a sense of disbelief or frustration with the delay in diagnosing the disease, rather than acceptance of the prognosis itself.
C. "I understand this is a disease that occurs mostly in older men." While this statement shows some awareness of the disease, it does not necessarily indicate acceptance. It may simply reflect an understanding of the demographics of prostate cancer without addressing the client's personal feelings or coping mechanisms.
D. "I do not have any use for those who say this disease is going to win." This statement may indicate resistance or defiance towards the negative outlook associated with the disease. It suggests a desire to maintain a positive attitude but does not necessarily reflect a full acceptance of the prognosis and its implications.
