Management of obstructed upper airway in a CONSCIOUS casualty consists of:a. Call ambulance/send for helpb. 5 back blowsc. 5 chest thrustsd. All of the above

The correct answer is d. All of the above.

Here's the step-by-step process:

1. Call ambulance/send for help: This is the first step in any emergency situation. It's important to get professional medical help on the way as quickly as possible.

2. 5 back blows: If the casualty is conscious and choking, delivering five sharp blows between their shoulder blades with the heel of your hand can help dislodge the obstruction.

3. 5 chest thrusts: If the back blows don't work, you can try giving five chest thrusts. These are similar to the compressions given during CPR, but they're sharper and meant to dislodge an obstruction rather than to restart the heart.

Remember, these steps should be performed only if the person is conscious and choking. If they become unconscious, you should begin CPR immediately and use an automated external defibrillator (AED) if one is available.

The correct answer is d. All of the above.

Here's why:

a. Call ambulance/send for help: This is the first step in any emergency situation. It's important to get professional medical help on the way as quickly as possible.

b. 5 back blows: This is a common first aid technique used to clear an obstruction from a person's airway. The rescuer uses the heel of their hand to deliver up to five sharp blows between the person's shoulder blades.

c. 5 chest thrusts: If back blows don't work, chest thrusts are the next step. The rescuer stands behind the person and uses both hands to apply pressure to the middle of the breastbone. This can help dislodge the obstruction.

So, all of these steps are part of the management of an obstructed upper airway in a conscious casualty.
