When a patient is prescribed an ACE inhibitor what medication should you avoid

What is the role of ADH?
Why is this medication rarely used for diuretics?
The carbonic anhydrase inhibitors are rarely used as diuretics because they produce only a weak diuresis and can contribute to metabolic acidosis.
Why are patients who take diuretics considered to be on fall precautions?
Diuretics reduce circulating blood volume, and orthostatic hypotension may increase the risk of falls.
What is the MOA? and what does it do?
- Blocks aldosterone
- Aldosterone increases sodium and water reabsorption
What are S/S of hyperkalemia
- Signs and symptoms of hyperkalemia include muscle weakness, fatigue, and bradycardia.
Why do we ADH to patients in shock or cardiac arrest?
What are the SE/AE of this medication?
Electrolyte imbalances, fatigue, vomiting, dizziness
What is the patient teaching someone about taking spironolactone?
- Spironolactone does such an efficient job of retaining K+ that hyperkalemia may develop. The risk of hyperkalemia is increased if the patient takes potassium supplements or is concurrently taking ACE inhibitors.
- give with food to promote reabsorption
