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 A
Explanation
Fluid overload, also called hypervolemia, is a condition in which the body has too much water.
It can cause edema, hypertension, shortness of breath, and cardiovascular problems.
Diuretics are medications that help the body remove excess fluid through urine.
They are commonly used to treat fluid overload caused by heart failure, kidney failure, cirrhosis, and other conditions.
Choice B is wrong because encouraging increased fluid intake would worsen the fluid overload and increase the risk of complications.
Choice C is wrong because providing a high-sodium diet would also worsen the fluid overload and increase the risk of complications.
Sodium is an electrolyte that regulates fluid balance in the body.
Excess sodium intake can cause water retention and increase blood pressure.
Choice D is wrong because elevating the affected extremities is not an appropriate intervention for fluid overload.
Elevating the extremities can help reduce swelling caused by local factors such as injury or inflammation, but it does not address the underlying cause of fluid overload.
Correct Answer is A
Explanation
Clearance = urine flow rate x urine concentration / plasma concentration. This is the formula for calculating the renal clearance of a substance that is neither reabsorbed nor secreted by the tubules. Renal clearance is the volume of plasma that would have to be filtered by the glomeruli each minute to account for the amount of that substance appearing in the urine each minute.
Choice B is wrong because it has the urine concentration and plasma concentration inverted.
This would give an incorrect value for renal clearance.
Choice C is wrong because it has the plasma flow rate instead of the urine flow rate.
Plasma flow rate is not directly related to renal clearance.
Choice D is wrong because it has both the plasma flow rate and the urine concentration and plasma concentration inverted.
This would give an incorrect value for renal clearance.
Normal ranges for renal clearance vary depending on the substance, age, sex, and body size.
For example, the normal range for creatinine clearance is 85-125 mL/min for males and 75-115 mL/min for females.
