help nurses! Need I & R for "altered urinary elimination"

help I need 3 more Interventions & Rationale for altered urinary elimination r/t damage to renal tissue (Renal cancer) And I just cant find/think of any more. I'm struggling. Help me out

this is what I have so far:

I - Monitor urinary elimination, including consistency, odor, volume and color

R - These parameters help determine adequacy of urinary function (Weber, 2005)

I - Instruct pt. to drink a minimum of 1500 - 2000 mL of fluids per day

R - Increased fluids during the day will increase urinary output and discourage bacterial growth (Weber, 2005)

I - Appraise pt. knowledge on effects of renal tissue damage on urinary elimination

R - Assessing the clients knowledge will provide a foundation for building a teaching plan based on his present understanding of his condition (Weber, 2005).

I - Describe the rational behind management, therapy, and treatment recommendations

R - Adequate information about treatment options is important to diminish anxiety, promote compliance, and enhance decision making (Weber, 2005)

I - Cleanse perineal are and keep dry

R - Perineal care decreases risk of skin irritation, breakdown, and development of ascending infection (Weber, 2005).

I - Monitor blood urea nitrogen (BUN), creatine, white blood cell (WBC) count, and urinalysis (UA).

R - These labratoriy tests reflect renal funtion and can identify complications (Weber, 2005).

I - Assess for signs of fluid overload: dyspnea, tachycardia, crackles, distended neck veins, and peripheral edema

R - Hydration is used to counterbalance effects of calcium and protein buildup. Overhydration needs to be prevented (Gulanick & Myers, 2011).
