Question 1 of 5
A 26-year-old patient with a history of polycystic kidney disease is admitted to the surgical unit after having knee surgery. Which of the routine postoperative orders is most important for the nurse to discuss with the health care provider?
Correct Answer: C
Rationale: Ketorolac (C), an NSAID, risks nephrotoxicity in polycystic kidney disease, necessitating discussion. Fluids (A), diet (B), and labs (D) are standard, but avoiding renal harm is key, making C the order to clarify.
Question 2 of 5
The nurse is caring for a patient who is admitted with pneumonia. The nurse notes a blood urea nitrogen (BUN) of 32 mg/dL and creatinine of 0.8 mg/dL. What is the most probable explanation for this finding?
Correct Answer: C
Rationale: Elevated BUN (32 mg/dL) with normal creatinine (0.8 mg/dL) suggests dehydration (C), concentrating blood urea. Kidney damage (A) would raise creatinine, septicemia (B) isn't indicated, and malnutrition (D) lowers BUN, making C the likely cause.

Correct Answer: A
Rationale: Dullness post-voiding (A) indicates incomplete bladder emptying, as urine muffles sound. Kidney enlargement (B), obstruction (C), or dehydration (D) don't cause bladder dullness directly; they reduce urine flow, making A the interpretation.
