Which is the hormone that stimulates the release of aldosterone from the adrenal cortex.
Renin.
Angiotensin I.
Angiotensin II.
Antidiuretic hormone (ADH).
The Correct Answer is C
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.

Correct Answer is B
Explanation
Hyponatremia is a condition where the serum sodium level is below 135 mEq/L, which can affect the normal functioning of cells, muscles, and organs.
Administering intravenous fluids with a high sodium content can help restore the sodium balance and prevent complications such as confusion, seizures, and coma.
Choice A is wrong because encouraging the patient to consume a low-sodium diet would worsen the hyponatremia and increase the risk of electrolyte imbalance.
Choice C is wrong because administering a diuretic medication to increase urine output would cause further fluid and sodium loss and exacerbate the hyponatremia.
Choice D is wrong because encouraging the patient to increase fluid intake would dilute the sodium concentration and lower the serum sodium level.
Correct Answer is C
Explanation
A urinary tract infection (UTI) is a common complication after bladder cancer surgery, especially if the patient has an indwelling urinary catheter.
A UTI can cause symptoms such as fever, pain, burning or urgency when urinating, blood in the urine, or cloudy or foul-smelling urine.
Choice A is wrong because urinary retention (the inability to empty the bladder completely) is unlikely to occur with an indwelling catheter, which drains urine continuously.
Choice B is wrong because urinary incontinence (the loss of bladder control) is more likely to occur after partial or radical cystectomy, which remove part or all of the bladder, respectively.
In these cases, reconstructive surgery is needed to create a new way for urine to leave the body.
Choice D is wrong because urinary urgency (the sudden and strong need to urinate) is also more likely to occur after partial or radical cystectomy, which can affect the nerves and muscles that control urination.
Urinary urgency can also be a symptom of a UTI, but it’s not the only one.
