1. • True
   • False

3. True or False: One type of acute coronary syndrome is STEMI.

1. • True
   • False

4. True or False: If atropine is unsuccessful in treating bradycardia, it is doubtful that the individual will respond to any other interventions.

1. • True
   • False

5. True or False: Medication is the only treatment for an unstable tachycardic individual.

1. • True
   • False

6. All of the following are examples of advanced airways EXCEPT:

1. • Laryngeal mask airway (LMA)
   • Esophageal-tracheal tube (combitube)
   • Endotracheal tube (ET tube)
   • Oropharyngeal airway (OPA)

7. What is the purpose of defibrillation?

1. • To treat symptomatic bradycardia.
   • To stun the heart and allow its normal pacemaker to resume electrical activity.
   • To restart the heart.
   • To provide electrically stimulated contraction of the heart.

8. Early defibrillation is critical for individuals with sudden cardiac arrest for the following reasons EXCEPT:

1. • The probability of successful defibrillation decreases quickly over time.
   • The most effective treatment for ventricular fibrillation (VF) is electrical defibrillation.
   • A common initial rhythm in out-of-hospital witnessed sudden cardiac arrest is ventricular fibrillation (VF).
   • Individuals in asystole respond well to early defibrillation.

9. True statements about AED use in special situations include all of the following EXCEPT:

1. • Leave medication patches in place and place the AED electrode pads directly over the patch.
   • Do not use an AED in water.
   • Extra care in placing electrode pads may be needed in individuals with a hairy chest.
   • Do not place the AED electrode pads directly over an implanted defibrillator or pacemaker.

10. When using a monophasic defibrillator, how many joules should be delivered per shock?

1. • 360 J
   • 200 J
   • 300 J
   • 150 J

11. Immediately following a shock, CPR should be resumed for how many minutes?

1. • Two minutes
   • 10 minutes
   • Five minutes
   • One minute

12. For persistent VF/pulseless VT, vasopressors that may be given during CPR include:

1. • Magnesium and potassium
   • Epinephrine and dopamine
   • Amiodarone and diltiazem
   • Epinephrine and vasopressin

13. The order of priority for routes of access for drugs is:

1. • IV route, IO route, ET route
   • IO route, IV route, ET route
   • ET route, IV route, IO route
   • IO route, ET route, IV route

14. Medications administered in the early treatment of suspected ACS include:

1. • Oxytocin, ibuprofen, nitroglycerine, and fentanyl
   • Oxycodone, aspirin, nitrous oxide, and morphine
   • Oxygen, vasopressin, nitric oxide, and meperidine
   • Oxygen, aspirin, nitroglycerin, and morphine

15. What is the only means of identifying ST-elevation MI (STEMI)?

1. • Fibrinolytic checklist
   • Coronary angiography
   • None of the above
   • 12-lead ECG

Answer 1

Ans) True

Explaination:

- 100% oxygen is acceptable for early intervention, but not for extended periods of time. Oxygen should be titrated, so that individual's pulse oximetry is greater than 94% to avoid oxygen toxicity.

True

Explaination:

- If atropine fails to alleviate symptomatic bradycardia, TCP is initiated. Ideally, the patient receives sedation prior to pacing, but if the patient is deteriorating rapidly, it may be necessary to start TCP prior to sedation.

True

Explaination:

Featured snippet from the web
Acute Coronary Syndrome is a name given to three types of coronary artery disease that are associated with sudden rupture of plaque inside the coronary artery: Unstable angina. Non-ST segment elevation myocardial infarction or heart attack (NSTEMI) ST segment elevation myocardial infarction or heart attack (STEMI).

False

Explaination:

- Atropine: The first drug of choice for symptomatic bradycardia. Dopamine: Second-line drug for symptomatic bradycardia when atropine is not effective. Epinephrine: Can be used as an equal alternative to dopamine when atropine is not effective.
