1
Q

Workload of the hear is divided into

A

preload and afterload

2
Q

Preload

A

volume of blood entering the right side of the heart

3
Q

Afterload

A

force needed to push blood out of the ventricles

4
Q

•If the heart is not working properly, it can compensate by a few mechanisms:

A

–Increase heart rate

–Increase stroke volume

–Increase efficiency

–Enlarge itself

5
Q

Positive inotropic drugs

A

increas the force of myocardial contration

6
Q

Negative inotropic drugs

A

decrease the force of myocardial contration

7
Q

Cardiac glycosides function

A

increase the strength of cardiac contractions, decrease heart rate, have an antiarrhythmic effect, and decrease signs of dyspnea

8
Q

Positive inotropes side effects

A

anorexia

vomiting

diarrhea

cardiac arrhythmias

9
Q

Catecholmines function

A

increase the force and rate of myocardial contraction, constrict peripheral blood vessels and increase blood glucose levels

10
Q

Antiarrhythmic drugs function

A

Used to correct variation in the normal beating of the heart (which can lead to reduced cardiac output)

11
Q

Vasodilators function

A

Drugs used to dilate arteries and/or veins, which alleviates vessel constriction and improves cardiac output

12
Q

Diuretics function

A

Drugs that increase the volume of urine excreted by the kidneys and thus promote the release of water from the tissues (lowers the fluid volume in tissue)

13
Q

Anticoagulants function

A

Inhibit clot formation by inactivating one or more clotting factors

–Used to inhibit clotting in catheters, to prevent blood samples from clotting, to preserve blood transfusions, and to treat emboli

14
Q

Hemostatic drugs

A

–Help promote the clotting of blood

–May be parenteral or topical

15
Q

Types of Parenteral Hemostatic drugs

A

Vitamin K1

Protamine sulfate

16
Q

Types of Topical Hemostatic drugs

A
  • silver nitrate
  • hemostat power
  • gelfoam gelatin sponges
  • thrombogen topical thrombin solution
