Question

1. is:
   • Epinephrine and vasopressin
   • Rapid transfusion
   • Lidocaine and magnesium
   • Early reperfusion therapy

2. Tachycardia is defined as a heart rate greater than:

1. • 90 beats per minute
   • 120 beats per minute
   • 100 beats per minute
   • 150 beats per minute

3. Signs of unstable tachycardia may include all of the following EXCEPT:

1. • Acute heart failure
   • Hypotension
   • Ischemic chest discomfort
   • Abdominal tenderness

4. What is the first step in the treatment of persistent tachycardia (heart rate > 150 bpm) causing hypotension, altered mental status, and signs of shock?

1. • Administer a calcium channel blocker
   • Obtain a 12-lead ECG
   • Defibrillation
   • Synchronized cardioversion

5. Signs and symptoms of a stroke may include:

1. • Sudden weakness or numbness of the face, arm, or leg
   • Sudden trouble seeing in one or both eyes
   • Dizziness or loss of balance or coordination
   • All of the above

6. What does a P wave on an ECG reflect?

1. • Ventricular contraction
   • AV block
   • Ventricular repolarization
   • Atrial contraction

7. You are alone when you encounter an individual in cardiac arrest. They are not breathing, have no pulse, and have no suspected cervical spine trauma. Which maneuver should you use to open the airway?

1. • Blind finger-sweeps
   • Head-tilt only
   • Jaw-thrust maneuver
   • Head-tilt-chin-lift maneuver

8. The BLS Survey changed in the 2010 AHA update. Which of the following describes this change?

1. • Start with chest compressions instead of two rescue breaths.
   • Survey is no longer represented by the mnemonic ABCD; instead, it is represented by the numbers 1, 2, 3, 4.
   • Chest compressions should be continued while preparing the AED to minimize breaks.
   • All of the above

9. This is an example of which type of heart rhythm?
   sal-42-acls
   

1. • Atrial flutter
   • Ventricular fibrillation
   • Atrial fibrillation
   • Pulseless electrical activity

10. During the post-cardiac arrest phase, which of the following medications can be used to treat hypotension?

1. • Dopamine
   • Epinephrine
   • Norepinephrine
   • All of the above

Answer 1

Tachycardia is defined as heart rate more than 100 beats per minute

So answer is C..

Unstable tachycardia does not include abdominal tenderness.So answer is D.

The first step will be to get 12 lead ECG.So answer is B.

Answer is all of the above.

P wave actually indicates atrial depolarization, which is followed by atrial contraction. So answer is D.

Though there is no suspected cervical spine trauma,still risk should not be taken and only head tilt should be done.

So answer is B.
