Certified Hyperbaric Technologist Test CHT Patient Care and Safety in the Hyperbaric Environment 4

Question 1

A patient with a history of seizures is being treated. Which monitoring priority is most important?

Accepted Answer

Watching for early CNS oxygen toxicity signs

Answer

Seizure-prone patients are at higher risk for oxygen-induced seizures, so early CNS toxicity monitoring is critical.

Question 2

What is the recommended action if a patient cannot equalize ear pressure despite coaching?

Accepted Answer

Pause treatment and consider ENT evaluation or myringotomy

Answer

Persistent inability to equalize may require ENT consultation or tympanostomy tubes to prevent barotrauma.

Question 3

Why are electronic devices like cell phones prohibited inside the chamber?

Accepted Answer

They are potential ignition sources in an oxygen-rich environment

Answer

Battery-powered electronics can spark or overheat and serve as ignition sources in oxygen-enriched air.

Question 4

A patient on chemotherapy with bleomycin is referred for HBO. What is the concern?

Accepted Answer

Increased risk of pulmonary oxygen toxicity

Answer

Bleomycin sensitizes lung tissue to oxygen, raising the risk of pulmonary toxicity during HBO.

Question 5

What is the technologist's role regarding informed consent before HBO therapy?

Accepted Answer

Obtain and document that consent was given before treatment begins

Answer

Confirming and documenting informed consent before treatment is part of safe patient care.
