CHT Patient Assessment & Clinical Evaluation 3

Question 1

A patient undergoing hyperbaric oxygen therapy for carbon monoxide poisoning suddenly becomes agitated and confused inside the chamber. The FIRST priority is to:

Accepted Answer

Initiate emergency decompression and remove the patient

Answer

Neurological deterioration may signal oxygen toxicity or worsening CO toxicity requiring immediate controlled decompression and patient removal for evaluation.

Question 2

When performing a neurological baseline assessment before HBO treatment for arterial gas embolism, the technician should document which of the following?

Accepted Answer

Pupil size and reactivity, motor strength, and level of consciousness

Answer

A thorough neurological baseline including pupils, motor function, and consciousness level allows tracking of treatment response in AGE patients.

Question 3

A patient with an implanted pacemaker presents for HBO therapy. The technician should FIRST:

Accepted Answer

Verify that the pacemaker model is rated as pressure-stable and consult cardiology

Answer

Most modern pacemakers are pressure-stable, but specific model verification and cardiologist clearance are required before HBO treatment.

Question 4

During patient assessment, you note a Braden Scale score of 12. This indicates the patient is at:

Accepted Answer

High risk for pressure ulcer development

Answer

A Braden Scale score of 12 falls in the high-risk range (≤12), indicating significant susceptibility to pressure injuries relevant to wound care patients.

Question 5

A patient reports a recent upper respiratory infection with nasal congestion prior to their scheduled HBO session. The technician should be MOST concerned about:

Accepted Answer

Inability to equalize middle ear and sinus pressure during compression

Answer

Nasal congestion impairs Eustachian tube function, making it difficult or impossible to equalize middle ear pressure, increasing barotrauma risk.
