A client is diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH).
The nurse would monitor the client for which of the following electrolyte imbalances?
Hyponatremia.
Hypernatremia.
Hyperkalemia.
Hypokalemia.
The Correct Answer is A
SIADH is a condition in which your body makes too much antidiuretic hormone (ADH), which controls how your body releases and conserves water.
SIADH makes it harder for your kidneys to release water and causes the levels of electrolytes, like sodium, to fall due to water retention.
This leads to hyponatremia, which is when you have low levels of sodium in your blood.
Choice B is wrong because hypernatremia is when you have high levels of sodium in your blood.
This can occur due to dehydration, excessive salt intake, or kidney problems.
Choice C is wrong because hyperkalemia is when you have high levels of potassium in your blood.
This can occur due to kidney failure, acidosis, or certain medications.
Choice D is wrong because hypokalemia is when you have low levels of potassium in your blood.
This can occur due to vomiting, diarrhea, diuretics, or alkalosis.

Correct Answer is C
Explanation
According to Healthline1 and Mayo Clinic, the normal blood sodium level is between 135 and 145 milliequivalents per liter (mEq/L).
Choice A is wrong because it is the normal range for potassium, not sodium.
Choice B is wrong because it is the normal range for calcium, not sodium.
Choice D is wrong because it is the normal range for chloride, not sodium
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.
