A patient with chronic kidney disease (CKD) is being evaluated for medication management. Which of the following medications should be avoided due to its potential nephrotoxic effects?
Atorvastatin
Losartan
Vancomycin
Aspirin
The Correct Answer is C
A. Atorvastatin: Atorvastatin is a statin used to manage cholesterol levels. It is generally safe for use in patients with CKD.
B. Losartan: Losartan is an angiotensin II receptor blocker (ARB) used to manage hypertension and protect the kidneys in diabetic nephropathy. It can be beneficial in CKD patients.
C. Vancomycin: Vancomycin is an antibiotic known to be nephrotoxic, especially in patients with compromised kidney function. It should be used with caution or avoided in patients with CKD.
D. Aspirin: While aspirin can have adverse effects on the kidneys at high doses, its nephrotoxic potential is lower than that of vancomycin. In low doses, aspirin is commonly used for cardiovascular protection, even in patients with CKD.

Correct Answer is B
Explanation
A. Costovertebral angle tenderness: Costovertebral angle tenderness is more indicative of pyelonephritis (kidney infection) rather than cystitis, as it signals an upper urinary tract infection.
B. Suprapubic tenderness: Suprapubic tenderness is a classic sign of cystitis. This symptom, combined with dysuria and increased urinary frequency, strongly supports the diagnosis.
C. Abdominal distention: Abdominal distention is not typically associated with cystitis. It may suggest other conditions like bowel obstruction or ascites.
D. Lower extremity edema: Lower extremity edema is not a common finding in cystitis. It is more associated with systemic conditions like heart failure or kidney disease.
Correct Answer is D
Explanation
A. "You will need to avoid high-fiber foods to prevent blockages": While caution with high-fiber foods may be needed initially, long-term, a balanced diet including fiber can help regulate bowel movements and prevent constipation. This statement could cause unnecessary concern.
B. "The output from your stoma will be mostly liquid": This statement is incorrect for a sigmoid colostomy, where the stool tends to be more formed since it is further along the digestive tract. Liquid output is more common with ileostomies or colostomies higher in the colon.
C. "You will need to change your colostomy bag every 24 hours":
Rationale: Colostomy bag changes depend on several factors, including the type of appliance and personal preferences. Bags are not changed on a strict 24-hour schedule but are emptied as needed and changed every few days or when required.
D. "Your stoma will be located on the left side of your abdomen." A sigmoid colostomy is typically located on the left lower quadrant of the abdomen, as this is the anatomical location of the sigmoid colon.
