ACLS review: Asystole/PEA Review Questions Part 2

11. All of the following are true regarding drug delivery via the endotracheal route EXCEPT:

1. Results in lower blood concentrations than the same dose given intravascular route.
2. Give 2 to 2½ times the recommended IV dose.
3. Enables drug delivery similar to that achieved by peripheral venous access at comparable doses.
4. Providers should dilute the recommended dose in 5 to 10 ml of water or normal saline and inject the drug directly into the endotracheal tube

12. All of the following are beneficial effects of epinephrine EXCEPT

a.    Increases myocardial contraction

b.    Increases peripheral vascular vasoconstriction

c.    Increases myocardial oxygen consumption

d.    Increases heart rate

13. If PETCO2 is _______, it is reasonable to consider trying to improve CPR quality by optimizing chest compression parameters

1. <60 mm Hg
2. >10 mm Hg
3. >40 mm Hg
4. <10 mm Hg

14. A patient weighing 100kg is being treated for Asystole.  What is the maximum dose of epinephrine that can be given?

1. 1 mg/kg/min
2. 1 units/kg
3. 1 mcg/min
4. 1 mg

15.  A state of severely compromised perfusion in which a palpable pulse is absent but a weak pulse can be detected by doppler or echocardiography.

1. Asystole
2. Becks Triad
3. Acute coronary syndrome
4. Pseudo-PEA

16 Name the drug: Stimulates alpha and beta adrenergic receptors. Produces bronchodilation and increases heart rate and force of contractions.  Increases the electrical activity in the myocardium and automaticity.

1. Epinephrine
2. Dopamine
3. Sodium Bicarbonate
4. Atropine

17. Name the drug: Neutralizes excess buildup of acid caused by severe hypoxic states, helps restore normal pH

1. Epinephrine
2. Dopamine
3. Sodium Bicarbonate
4. Atropine

18.  When treating a patient for PEA and asystole it is important to look for underlying problems that may have triggered the cardiac event.  The most common problems are called the 5Hs and the 5Ts.  Name the 5 Hs.
