QUESTIONS AND COREECT DETAILED ANSWERS

AGRADE

• Defibrillate immediately.

A 53-year-old woman is unresponsive. The cardiac monitor initially showed a narrow- QRS tachycardia at 220 beats/min. Her BP was 50 mm Hg by palpation and her ventilatory rate was 10 breaths/min. Supplemental oxygen therapy was initiated and an IV established before the patient's collapse. You promptly delivered a synchronized shock. Reassessment reveals the patient is not breathing and has no pulse. The cardiac monitor now reveals the rhythm shown. What course of action should you take at this time?

• Defibrillate immediately.
• Perform cardiopulmonary resuscitation (CPR) for 2 minutes and then prepare to

defibrillate.

• Place an advanced airway and then begin transcutaneous pacing.
• Press the "Sync" control and deliver another synchronized shock.
• Perform synchronized cardioversion with 50 to 100 J for the initial shock.

An unstable patient with a narrow-QRS tachycardia requires electrical therapy. You have a biphasic defibrillator available to you. Which of the following correctly reflects the recommended energy dose that should be delivered in this situation?

• Defibrillate with 120 joules (J).
• Defibrillate with 360 J.
• Perform synchronized cardioversion with 50 to 100 J for the initial shock.
• Perform synchronized cardioversion with 100 to 200 J for the initial shock.
• Using continuous waveform capnography. 1 / 3

The preferred method used to verify the proper placement of an endotracheal tube is:

• Obtaining a chest radiograph.
• Using continuous waveform capnography.
• Auscultating the presence of bilateral breath sounds.
• Observing adequate chest rise with positive pressure ventilation.
• The team leader should encourage a respectful exchange of ideas.

Which of the following is incorrect with regard to the events of a typical resuscitation effort?

• The team leader should state his or her instructions one at a time.
• The team leader should encourage a respectful exchange of ideas.
• Team members must be knowledgeable about current resuscitation algorithms.
• Team members should be encouraged to confer among themselves throughout the

resuscitation effort.

• Epinephrine should be given as soon as feasible after the onset of cardiac

arrest associated with a nonshockable rhythm.Which of the following statements is correct about the use of medications during cardiac arrest?

• Amiodarone is the drug of choice for cardiac arrest resulting from asystole.
• Lidocaine is contraindicated in cardiac arrest associated with a shockable rhythm.
• Epinephrine should be given as soon as feasible after the onset of cardiac arrest

associated with a nonshockable rhythm.

• Vasopressin can be substituted for either the first or second dose of epinephrine in

the treatment of cardiac arrest.

• STE is present in leads V1 to V4. An anterior STEMI is suspected.

This 12-lead ECG is from a 50-year-old man complaining of chest discomfort.

Which of the following is true regarding this 12-lead ECG?

• This 12-lead reveals no significant findings. 2 / 3

• STE is present in leads V1 to V4. An anterior STEMI is suspected.
• STE is present in leads I, aVR, and V6. A lateral STEMI is suspected.
• STD is present in leads III and aVF. An inferior STEMI is suspected.

D. Second-degree AV block (2:1 AV block).

A 65-year-old man is complaining of a sudden onset of dizziness. He is awake, alert, and diaphoretic. The patient states that his symptoms began 45 minutes ago while cleaning his garage. He denies chest pain, shortness of breath, and nausea. The patient's breath sounds are clear bilaterally. His BP is 78/50 mm Hg, ventilations 18 breaths/min. His SpO2 on room air is 96%.The cardiac monitor reveals the following rhythm.

This rhythm is:

• Junctional rhythm.
• Sinus bradycardia.
• Third-degree atrioventricular (AV) block.

D. Second-degree AV block (2:1 AV block).

• Administer atropine 0.5 mg IV.

A 65-year-old man is complaining of a sudden onset of dizziness. He is awake, alert, and diaphoretic. The patient states that his symptoms began 45 minutes ago while cleaning his garage. He denies chest pain, shortness of breath, and nausea. The patient's breath sounds are clear bilaterally. His BP is 78/50 mm Hg, ventilations 18 breaths/min. His SpO2 on room air is 96%.

An IV is in place. Your best course of action will be to:

• Defibrillate immediately.
• Administer atropine 0.5 mg IV.
• Administer amiodarone 300 mg IV.
• Administer vasopressin 40 units IV.
• Is indicated and should be delivered using a nasal cannula.
