Answer

Place a wedge under the right hip to tilt 15-30 degrees right

Answer

Keep patient supine with no tilt to maximize compression effectiveness

Answer

Tilt 45 degrees left to fully relieve aortocaval compression

Question 2

Which dysrhythmia is most commonly associated with hypothermic cardiac arrest at core temperatures below 30°C (86°F)?

Accepted Answer

Ventricular fibrillation

Answer

Asystole

Answer

Pulseless electrical activity

Answer

Atrial fibrillation with complete heart block

Question 3

A patient is rescued from a house fire and is in cardiac arrest with suspected cyanide toxicity. After standard ACLS, what antidote should be administered?

Accepted Answer

Hydroxocobalamin 5g IV

Answer

During resuscitation of a patient with tension pneumothorax, which finding confirms successful needle decompression?

Accepted Answer

Rush of air upon needle insertion and return of pulses

Answer

Question 5

In pediatric drowning resuscitation, which modification to standard CPR protocol is recommended?

Accepted Answer

Begin with 5 rescue breaths before starting chest compressions

Answer

Start with 30 compressions before any ventilations regardless of age

Answer

Avoid ventilations entirely until advanced airway is placed

Answer

Question 6

A patient with known hyperkalemia is in cardiac arrest with a wide-complex rhythm. Which medication should be given first?

Accepted Answer

Calcium chloride 1g IV

Answer

Sodium bicarbonate 50 mEq IV

Answer

Regular insulin 10 units IV

Answer

Albuterol nebulization

Question 7
