Certified Hyperbaric Technologist Test CHT Patient Care and Safety in the Hyperbaric Environment 3

Question 1

During decompression a patient develops joint pain. What complication should the technologist suspect?

Accepted Answer

Decompression sickness

Answer

Joint pain during or after decompression is a classic sign of decompression sickness from nitrogen bubble formation.

Question 2

What is the correct technologist response if a fire is detected in a monoplace chamber?

Accepted Answer

Activate emergency decompression and follow facility fire protocol

Answer

Rapid emergency decompression and immediate fire protocol activation are required to protect the patient.

Question 3

Why must IV fluid bags be vented or use specialized equipment inside a chamber?

Accepted Answer

To stop air from being forced into the patient as pressure changes

Answer

Gas in IV systems expands and contracts with pressure, so venting prevents air embolism and dosing errors.

Question 4

A claustrophobic patient becomes anxious during compression. What is the best initial intervention?

Accepted Answer

Provide reassurance, communication, and coaching through the chamber intercom

Answer

Calm verbal reassurance and continuous communication usually manage mild claustrophobia without aborting treatment.

Question 5

What is the purpose of an air break during a hyperbaric oxygen treatment?

Accepted Answer

To reduce the risk of oxygen toxicity

Answer

Periodic air breaks reduce continuous oxygen exposure and lower the risk of CNS oxygen toxicity.
