|
What side effects are important to watch with beta-adrenergic blockers?
|
Bradycardia, Lethargy, GI disturbance, hypotension, CHF, bronchospasms, depression and impotence.
|
|
|
What is the action of ACE inhibitors?
|
Blocks the conversion of angiotensin I to angiotensin II, a vasoconstrictor. This block causes vasodilation and therefore decreases PVR, resulting in a decrease in sodium and water retention.
|
|
|
What is the action of Beta-adrenergic blockers?
|
Prevent sympathetic stimulation of the heart (blocks beta-receptors in the heart) which causes:
Decreased HR, Decreased Force of contraction and decreased rate of AV conduction. |
|
|
What is the action of Calcium Channel Blockers?
|
Blocks calcium influx into the beta-receptors, decrease the force of the myocardial contraction, reduce the heart rate and decrease PVR>
|
|
|
What is the typical drug therapy plan for a patient beginning anti-hypertensive therapy.
|
The initial drug selection starts with a thiazide diuretic, typically followed by a beta-adrenergic blocker or an ACE inhibitor or CCB.
|
|
|
When using Beta-adrenergic blockers, ACE inhibitors or Calcium Channel Blockers what is one very important nursing teaching that refers to how they should be taken? |
DO NOT stop taking medication abruptly. |
|
|
What are important nursing actions to do prior to administering a Beta-blocker? |
-Evaluate BP and pulse for significant changes. -Hold if SBP is below 90 mmHg |
|
|
What is important to know about diabetic patients taking beta-blockers?
|
Tachycardia (a symptom of hypoglycemia) is often masked as a result of beta1 blockade.
|
|
|
What hint can be used to identify beta-blockers?
|
They end in OLOL.
ex: Propranolol (Inderal), Atenolol (Tenormin) |
