The nurse is caring for a client in the emergency department. Exhibits Which of the following interventions should the nurse perform?

Rationale: A. Strict I&O: Monitoring intake and output is essential due to decreased urination, flank pain, and impaired kidney function. The elevated BUN and creatinine levels suggest renal impairment, and strict I&O helps assess fluid balance. B. Increase fluid intake: While hydration is important, increasing fluids should be done cautiously due to the client’s impaired kidney function. Given the elevated BUN and creatinine, the kidneys may not manage increased fluids without worsening fluid retention. C. Encourage protein supplements: Protein supplements are not recommended in kidney dysfunction, as they can worsen renal strain. Elevated BUN and creatinine levels indicate kidney impairment, and protein intake may aggravate the condition. D. Strain all urine: Straining all urine is necessary to capture any possible kidney stones, blood clots, or debris. The reddish-brown urine and positive blood in the urinalysis suggest hematuria, which may need further investigation.
