The nurse is assessing a patient with acute renal failure.
Which of the following would be a priority nursing intervention?
Administering a potassium-sparing diuretic.
Encouraging the patient to consume a high-sodium diet.
Monitoring urine output and fluid balance.
Administering intravenous antibiotics.
The Correct Answer is C
This is because acute renal failure is a condition where the kidneys lose their ability to filter waste and excess fluid from the blood. This can lead to fluid overload, electrolyte imbalances, and metabolic acidosis. Therefore, the nurse should monitor the patient’s urine output and fluid balance to assess the severity of the renal impairment and prevent complications.
Choice A is wrong because administering a potassium-sparing diuretic would worsen the patient’s hyperkalemia, which is a common complication of acute renal failure.
Choice B is wrong because encouraging the patient to consume a high-sodium diet would increase the patient’s fluid retention and blood pressure, which can further damage the kidneys.
Choice D is wrong because administering intravenous antibiotics is not a priority intervention for acute renal failure unless there is a specific indication of infection.

Correct Answer is C
Explanation
Dysuria, which means pain or a burning sensation when peeing, is a common symptom of urinary tract infection (UTI).
UTIs are caused by bacteria entering the urinary tract through the urethra and spreading to the bladder or kidneys.
Choice A is wrong because nausea is not a specific symptom of UTI, although it may occur if the infection spreads to the kidneys.
Choice B is wrong because diarrhea is not a symptom of UTI, but rather a condition that affects the digestive system.
Choice D is wrong because constipation is also not a symptom of UTI, but a problem with bowel movements.
Normal ranges for urine tests vary depending on the type of test and the laboratory that performs it.
However, some general ranges are:
Specific gravity: 1.005 to 1.030
pH: 4.6 to 8.0
Protein: less than 150 mg/dL Glucose: less than 130 mg/dL Ketones: none
Blood: none Nitrites: none
Leukocyte esterase: none Bacteria: none or few
White blood cells: less than 5 per high-power field Red blood cells: less than 3 per high-power field Epithelial cells: few
Correct Answer is C
Explanation
Angiotensin II is a hormone that stimulates the adrenal cortex to release aldosterone. Aldosterone is a hormone that helps regulate blood pressure by increasing the reabsorption of sodium and water and the excretion of potassium by the kidneys.
Choice A is wrong because renin is not a hormone but an enzyme that catalyzes the conversion of angiotensinogen to angiotensin I1.
Choice B is wrong because angiotensin I is an inactive precursor of angiotensin II that is converted by angiotensin-converting enzyme (ACE) in the lungs.
Choice D is wrong because antidiuretic hormone (ADH) is a hormone that regulates water balance by increasing the reabsorption of water by the kidneys, but it does not affect aldosterone secretion.
