What are side effects are important to watch with calcium channel blockers?
Hypotension, peripheral edema, flushing headache and GI upset.
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 the 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 is 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)
