BLS BLS Special Situations & Scenarios 3

Question 1

During CPR for a patient in cardiac arrest due to severe anaphylaxis, what treatment is the highest priority alongside CPR?

Accepted Answer

Epinephrine administration (intramuscular or IV)

Answer

Oral antihistamine (diphenhydramine)

Answer

Corticosteroids (methylprednisolone)

Answer

Bronchodilator inhaler only

Question 2

Should CPR be withheld in a trauma patient with suspected internal bleeding who has no pulse?

Accepted Answer

No — CPR must be performed for any pulseless patient regardless of suspected internal bleeding

Answer

Yes — CPR may worsen internal hemorrhage

Answer

Yes, but only if the suspected bleeding is abdominal

Answer

No, but compression depth should be reduced to 1 inch to limit further injury

Question 3

When is it safe to use an AED on a victim who was in contact with standing water?

Accepted Answer

After moving the victim away from standing water and quickly drying the chest

Answer

Always — water does not affect AED pad contact or shock delivery

Answer

Only if the victim is placed on a rubber mat first

Answer

Never use an AED near any source of water

Question 4

How does the initial BLS sequence for a drowning victim differ from a standard (non-asphyxia) cardiac arrest?

Accepted Answer

Begin with 2 rescue breaths before or at the start of compressions to address the hypoxia

Answer

No difference — start with 30 chest compressions immediately

Answer

Skip compressions entirely and provide only rescue breaths

Answer

Use a 15:2 ratio instead of the standard 30:2

Question 5

Which hazard must be eliminated before approaching a victim of electrocution?

Accepted Answer

The active electrical current source must be turned off or the victim moved away from it

Answer

Cold environmental temperature around the victim

Answer

Presence of bystanders crowding near the scene

Answer

Sunlight interfering with AED screen readability

Question 6

In pregnancy-related cardiac arrest, what intervention is considered if CPR remains unsuccessful after 4–5 minutes?

Accepted Answer

Emergency perimortem cesarean delivery to relieve aortocaval compression

Answer

Bilateral needle decompression of the chest

Answer

Increase compression rate to 140 per minute

Answer

Discontinue resuscitation efforts and document time of death
