Which is the hormone that stimulates the release of aldosterone from the adrenal cortex.

Metabolic acidosis is a condition in which there is excess acid in the body fluids.

It causes rapid breathing, confusion, tiredness, headache, and increased heart rate.

Rapid breathing is a compensatory mechanism that helps to lower the carbon dioxide levels and increase the pH of the blood.

Choice B is wrong because decreased respiratory rate would worsen the acidosis by retaining more carbon dioxide and lowering the pH of the blood.

Choice C is wrong because normal respiratory rate would not be adequate to compensate for the metabolic acidosis and would result in acidemia (low blood pH).

Choice D is wrong because irregular respiratory rate is not a typical response to metabolic acidosis and could indicate other problems such as brain injury or drug overdose.

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.
