Flashcards in Medication Safety Deck (20):
1

Angina Pectoris

Pain secondary to myocardial ischemia
Nitrates
Beta-blockers
Calcium Channel Blockers

2

Heart Failure

Inability of the heart tp pjmp adequate amounts of blood through the body
-Blood accumulates in the lungs, feet, legs, kidneys, liver, stomach, and other organs

3

Cardiovascular agents

Decreasing intravascular volume
Decreasing venous return preload
Decreasing afterload
improve cardiac functioning

4

Angiotension converting enzymes (ACE) inhibitors

Prevents the conversion of Angiotension I too Angiotension II
-Angiotension II is a potential vasoconstrictor and decreases peripheral arterial resistance
Decreases the secretion of aldosterone resulting in decreased sodium and water retention

5

ACE Inhibitors indications

Antihypertensive
Management of heart failure
Decreased systemic vascular resistance

6

ACE inhibitors side effects

Hypotension
Taste disturbances
Proteinuria, increased creatine
Monitor potassium possible retention
Dry cough
Angioedema
-Tongue/ lip swelling

7

ACE inhibitors nursing considerations

Monitor blood pressure and pulse
Monitor weight and assess patient for resolution of ffluid overload
Monitor BUN, creatine, and electrolytes
Big BP drop may occur in the first 1-3 hours after first dose

8

Nitrate

Reduction of myocardial oxygen consumption
Balanced supply and demand
Relaxes all smooth muscle
Are used to prevent and relieve angina attacks
Very short half Life
Vascular smooth muscle relaxationresulting in generalized vasodilation
Decreases peripheral venous resistance results in venous pooling of blood and decrease venous return to the heart
Decrease arteriolar resistance reduces systemic vascular resistance and arterial pressures

9

Nitroglycerin

Increases coronary blood flow by dilating coronary arteries
Vasodilation

10

Beta-Adrenengic blockers

For hypertension, angina, tachy arrythmias, migraines, MI prevention, anxiety

11

Beta blockers side effects

Fatigue
Weakness
Bradycardia
May lead to CHF or pulomonary edema
Impotence

12

Diuretics

Decreases intravascularr volume by increasing urination

13

Loop diuretics

Decrease urinary concentration and diluting increasing urinary water, dosium, potassium, calcium, hydrogen, and magnesium excretion

14

Lasix

Used for the treatment of CHF and hypertension

15

Lasix side effects

Dehydration
Hypochloremia
Hypokalemia
Hypomagnesaemia
Hyponatremia
Hypovolemia
Metabolic alkalosis

16

Calcium channel blockers

Block calcium entry into of vascular smooth muscle and myocardium
Dilates coronary arteries

17

Cardizem side effects

Arrythmias, CHF, peripheral edema, constipation, weight gain

18

Cardiac glycosides

Decreases conduction through the SA and AV node slowing HR
Strengths and increases force of contraction

19

Digoxin side effects

Fatigue
Bradycardia
Anorexia
Nausea and vomiting
Monitor apical pulse
Hold is HR less than 60

20

Anticoagulants

Used to prevent clot formation and extention
Prevent DVT, PE, atrial fibrillation with embolism, stroke, and MI
