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
This is because hyponatremia is a condition where sodium levels in your blood are lower than normal, usually due to too much water in your body that dilutes the sodium. A hypertonic saline solution is a fluid that has a higher concentration of sodium than blood, and it can help restore the normal sodium balance by drawing water out of the cells.
Choice A is wrong because restricting fluid intake may not be enough to correct severe hyponatremia, and it may worsen the symptoms of dehydration.
Choice C is wrong because encouraging increased fluid intake will further lower the sodium levels and increase the risk of complications such as brain swelling.
Choice D is wrong because administering a loop diuretic will cause more sodium and water loss from the kidneys, which can worsen hyponatremia and dehydration.
Normal ranges for blood sodium levels are between 135 and 145 milliequivalents per liter (mEq/L).
Hyponatremia is defined as a blood sodium level below 135 mEq/L1.
Correct Answer is B
Explanation
This is a priority nursing intervention for a client with acute kidney injury (AKI) because it helps to assess the renal function and fluid status of the client. Urine output is also an indicator of the response to treatment and the need for further interventions.
Choice A is wrong because pain medication is not a priority intervention for AKI unless the client has other conditions that cause pain.
Pain medication may also have adverse effects on the kidney function and should be used with caution.
Choice C is wrong because ambulation is not a priority intervention for AKI and may not be appropriate for a client who is fluid overloaded or hypotensive.
Ambulation may also increase the risk of falls and injury in a client who is confused or fatigued.
Choice D is wrong because assisting with meals is not a priority intervention for AKI and may not be necessary for a client who has adequate oral intake.
A client with AKI may also have dietary restrictions such as low protein, low potassium, low sodium, and low phosphorus, which should be considered when providing meals.
