CPR AED Advanced

Question 1

What is the main advantage of a biphasic waveform AED over older monophasic devices?

Accepted Answer

It is more effective at lower energy levels, reducing myocardial damage

Answer

It delivers more total energy

Answer

It can shock asystole

Answer

It does not require electrode pads

Question 2

When should pediatric AED electrode pads or attenuation keys be used?

Accepted Answer

For children aged 1-8 years (or under 25 kg) when available

Answer

For all patients under 18 years old

Answer

Only for infants under 6 months old

Answer

Pediatric pads are not necessary; adult pads can always be used

Question 3

What is the correct anteroposterior (front-to-back) electrode pad placement for AED use?

Accepted Answer

One pad on the front center of the chest, one pad on the back between the shoulder blades

Answer

One pad on the right upper chest, one pad on the left lower chest

Answer

Both pads on the anterior chest wall

Answer

One pad on the right lower chest, one on the left upper chest

Question 4

What should be done if a patient has a hairy chest when applying AED electrode pads?

Accepted Answer

Firmly press and rip off the first set of pads to remove hair, then apply a new set

Answer

Apply pads directly over the hair without concern

Answer

Wet the chest to improve conductivity

Answer

Use gel to compensate for poor contact

Question 5

What is the significance of an AED's rhythm analysis algorithm in the context of shock delivery?

Accepted Answer

It detects VF and pVT patterns and advises shock, while detecting non-shockable rhythms and advising no shock

Answer

It can identify all cardiac rhythms and recommend treatment

Answer

It delivers multiple shocks automatically without user input

Answer

It monitors the patient's blood pressure to determine shock timing

Question 6

A patient is found to have an implanted cardioverter-defibrillator (ICD). How does this affect AED pad placement?

Accepted Answer

Place AED pads at least 1 inch away from the ICD device and in a standard or alternate position

Answer

An ICD means an AED should never be used on the patient

Answer

Place one pad directly over the ICD to synchronize shock delivery

Answer

Remove the ICD before applying AED pads

Question 7

What should a rescuer do if the patient is lying in water when using an AED?

Accepted Answer

Move the patient to a dry surface before applying pads and using the AED

Answer

Apply pads and shock immediately while in water

Answer

Use the AED in water only if both rescuers are wearing rubber gloves

Answer

Delay AED use until the patient is completely dry

Question 8

In an automated external defibrillator with a 'manual override' feature, when might a trained healthcare provider choose to use this mode?

Accepted Answer

To perform synchronized cardioversion for a patient with a pulse in an unstable tachyarrhythmia

Answer

To shock any rhythm including non-shockable ones

Answer

To bypass the charging phase and shock faster

Answer

To reduce shock energy below manufacturer settings

Question 9

What is the recommended energy for the first defibrillation attempt with a biphasic AED when treating adult VF/pVT?

Accepted Answer

120-200 joules (manufacturer specified) or 200 joules if unknown

Answer

50-100 joules

Answer

300 joules

Answer

360 joules

Question 10

How often should AED electrode pads be replaced in a maintenance program?

Accepted Answer

According to manufacturer's expiration date, typically every 2-5 years

Answer

Every 6 months regardless of use

Answer

Only when they appear damaged

Answer

Every year without exception
