What is the nursing interventions for captopril?
Risk of hypotension may be decreased by discontinuing diuretics or cautiously increasing salt intake 2–3 days prior to beginning captopril. Monitor BP closely. Resume diuretics if BP is not controlled. Administer 1 hr before meals or 2 hr after meals.
What administration considerations apply to captopril?

What is the mechanism of action of captopril?
Mechanism of action Captopril blocks the conversion of angiotensin I to angiotensin II and prevents the degradation of vasodilatory prostaglandins, thereby inhibiting vasoconstriction and promoting systemic vasodilation.
When should you not give captopril?

Dizziness, lightheadedness, or loss of taste may occur as your body adjusts to the medication. Dry cough may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Do ACE inhibitors cause low sodium?
An ACE inhibitor can contribute to hyponatremia regardless of the length of the administration period. However, inappropriate secretion of ADH associated with ACE inhibitors may be overlooked in daily medical practice because, by themselves, ACE inhibitors induce symptomatic hyponatremia only very rarely.
How does captopril contribute to a reduction of a client’s blood pressure?
ACE inhibitors are medications that slow (inhibit) the activity of the enzyme ACE and decrease the production of angiotensin II. As a result, blood vessels enlarge or dilate, and blood pressure is reduced.
Captopril competitively inhibits the conversion of angiotensin I (ATI) to angiotensin II (ATII), thus resulting in reduced ATII levels and aldosterone secretion. It also increases plasma renin activity and bradykinin levels. Reduction of ATII leads to decreased sodium and water retention.
How do you reduce the risk of hypotension from captopril?
Correct volume depletion, if possible, before initiation of therapy due to possible precipitous drop in BP during first 1–3 hr following first dose. Risk of hypotension may be decreased by discontinuing diuretics or cautiously increasing salt intake 2–3 days prior to beginning captopril.
What is hyponatremia and hypernatremia NCLEX?
Hyponatremia and Hypernatremia NCLEX Review Care Plans Nursing Study Guide on Hyponatremia and Hypernatremia Hyponatremia and hypernatremia are conditions that refer to the concentration of sodium in the blood.
