Questions on the Urinary System Questions
Question 1 of 5
Which of the following is incorrect concerning ADH?
Correct Answer: C
Rationale: ADH increases collecting duct water permeability (C is incorrect), concentrating urine, not decreases it. Osmolarity (A), alcohol (B), and pituitary storage (D) are true, making C the error.
Question 2 of 5
What action should the nurse take first when a patient's urine dipstick test indicates a small amount of protein?
Correct Answer: C
Rationale: Normally the urinalysis will show zero to trace amounts of protein, but some medications may give false-positive readings. The other actions by the nurse may be appropriate but checking for medications that may affect the dipstick accuracy should be first.
Question 3 of 5
In the accompanying figure, what is the nurse assessing via percussion?
Correct Answer: D
Rationale: The nurse in the photo is using indirect percussion to determine the presence or absence of costovertebral angle (CVA) tenderness, which suggests pyelonephritis or polycystic kidney disease. The liver size would be percussed from the anterior direction with the patient positioned supine. Chest stability and excursion are determined by palpating and observing for symmetry of expansion. Pulmonary tissue density would be determined by tapping the interphalangeal joint over the lung fields and listening for resonance.
Question 4 of 5
The nurse is caring for a patient who has a renal biopsy. For which complication would the nurse monitor the patient during the 24 hours after the procedure?
Correct Answer: A
Rationale: Bleeding (A) is the primary post-biopsy risk, indicated by bloody urine or vital sign changes, requiring immediate monitoring. Infection (B), obstruction (C), and polyuria (D) are less urgent, making A the key complication.
Question 5 of 5
The nurse is caring for a patient who has acute kidney injury. Which diagnostic test result would most support this diagnosis?
Correct Answer: B
Rationale: A normal 24-hour creatinine clearance of 100 mL/min is the most accurate test for renal function.
