• Antiarrhythmics
• Angiotensin-converting enzyme inhibitors
• Potassium channel blockers
• Calcium channel blockers
• Diuretics
• Antihemorrhagic agents
• Anticoagulants
• Hematinics
• Beta- blockers

Question 2

Which Cardiovascular class stimulates the heart and increases cardiac muscle strenght

Answer 2

Positive inotropic agents

Question 3

What are the 3 types of positive inotropic agents

Answer 3

• Glycosides
• Catecholamines
• Benzimidazole-Pyridazinones

Question 4

Which type of positive inotropic agent increases intracellular calcium increasing heart contractions and is used to treat heart failure

Answer 4

Glycosides

Question 5

Which type of positive inotropic agent are synthetic forms of naturally occuring neurotransmitters

Answer 5

Catecholamines

Question 6

Which type of positive inotropic agent causes vasodilation and strengthening of muscle contractions and is used to treat CHF in canines

Answer 6

Benzimidazole- pyridazinones

Question 7

Which Cardiovascular class affects ion channels and corrects electrical disturbances

Answer 7

Antiarrhythmics

Question 8

What are the 4 classes of antiarrhythmics

Answer 8

• Class 1 - blocks sodium channels, slowing
  conduction
• Class 2 - are beta- blockers that slow down
  SA and AV nodes
• Class 3 K+ channel blocker
• Class 4 Ca+ channel blocker

Question 9

Which Cardiovascular class blocks the action of the SNS and the beta-adrenergic substances like epinephrine

Answer 9

Beta-blockers

Question 10

Which Cardiovascular class inhibits the activity of the ACE enzyme causing the production of angiotensin 2 to decrease and ultimately causing dilated blood vessels, reduced blood pressure, and reduced excess fluid retention

Answer 10

Angiotensin- converting enzyme inhibitors

Question 11

Which Cardiovascular class blocks potassium from leaving the cell causing delayed repolarization and is used to treat arrhythmias

Answer 11

Potassium channel blockers

Question 12

Which Cardiovascular class blocks calcium from entering the muscles cells of the heart and arteries ultimately causing decreased contraction of the heart and dilated arteries

Answer 12

Calcium channel blockers

Question 13

Which Cardiovascular class is used to prevent or decrease symptoms of hypertension, heart failure, diabetes, edema, and liver/kidney disease and can cause dehydration or excessive thirst

Answer 13

Diuretics

Question 14

What are the 2 types of Diuretics

Answer 14

• Loop diuretics
• Potassium- sparing diuretics

Question 15

Which type of Diuretic causes the kidneys to excrete more fluid by interfering with salt and water transport across the loop of Henle ultimately causing an increase in urination

Answer 15

Loop diuretics

Question 16

Which type of Diuretic are weak and help retain potassium by interfering with the potassium-sodium exchange of the distal convoluted tubule

Answer 16

Potassium- sparing diuretics

Question 17

Which Cardiovascular class is a substance used to stop or reduce blood flow with local, topical, and systemic versions

Answer 17

Antihemorrhagic agent

Question 18

Which Cardiovascular class prevents clotting , strokes and heart attacks

Answer 18

Anticoagulants

Question 19

Which Cardiovascular class increases hemoglobin synthesis or stimulates bone marrow to produce RBCs to treat anemias

Answer 19

Hematinics
