What organ is contained in the cranial cavity?

Choice A rationale:

Using a fire extinguisher should not be the nurse's first action in this situation. The nurse's priority is to ensure the safety of the clients and staff in the vicinity. Attempting to use a fire extinguisher might not be effective and can potentially cause harm, especially if the fire spreads quickly.

Choice B rationale:

Activating the fire alarm is the nurse's priority in this situation. By activating the fire alarm, the nurse can alert everyone in the facility about the fire, ensuring that people are aware and can evacuate safely. This action initiates the facility's fire response protocol, leading to a quicker and organized response to the emergency.

Choice C rationale:

Moving clients to safety is important, but it is not the nurse's immediate priority in this situation. Activating the fire alarm should be done first to ensure that everyone in the facility is aware of the danger, and then the nurse can assist in moving clients to safety if necessary.

Choice A rationale: While ‘A’ is a vowel, it is not the most commonly used vowel when combining word parts in medical terminology.

Choice E rationale: ‘U’ is a vowel, but it is not the most commonly used vowel when combining word parts in medical terminology
