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 C
Explanation
This is because intravenous potassium supplementation is indicated for patients with profound hypokalemia (plasma K+ <2.5 mmol/L) or cardiac arrhythmia. The rate of infusion should not exceed 10 mmol/hour to prevent complications such as hyperkalemia, cardiac arrhythmias, and phlebitis.
Choice A is wrong because monitoring urine output every 8 hours is not sufficient to prevent complications from intravenous potassium replacement therapy.
Urine output should be monitored more frequently (at least every 4 hours) to assess renal function and fluid balance.
Choice B is wrong because administering potassium via a bolus injection is dangerous and can cause fatal cardiac arrhythmias.
Potassium should never be given by intravenous push or intramuscular injection.
Choice D is wrong because encouraging the client to eat potassium-rich foods is not appropriate for patients receiving intravenous potassium replacement therapy.
Oral potassium supplementation is preferred for patients with mild to moderate hypokalemia (plasma K+ 2.5-3.5 mmol/L) who can eat and absorb oral potassium.
Potassium-rich foods include potatoes, legumes, juices, seafood, leafy greens, dairy, tomatoes and bananas.
Correct Answer is ["B","C","D"]
Explanation
Hypercalcemia is a condition in which the calcium level in the blood is above normal.
This can cause various symptoms, such as confusion, constipation, and bradycardia (slow heart rate).
These are the clinical manifestations that the nurse would expect to observe in a client with hypercalcemia.
Choice A is wrong because muscle spasms are not a common symptom of hypercalcemia.
In fact, hypercalcemia can cause muscle weakness and pain.
Choice E is wrong because polyuria (excessive urination) is not a direct symptom of hypercalcemia, but rather a result of kidney problems caused by hypercalcemia.
Hypercalcemia can make the kidneys work harder to filter the excess calcium, leading to dehydration and thirst.
However, this does not necessarily mean that the client will have polyuria.
Normal ranges for calcium levels in the blood are 8.5 to 10.2 mg/dL (milligrams per deciliter) or 2.1 to 2.6 mmol/L (millimoles per liter).
