CHT Patient Assessment & Clinical Evaluation 2

Question 1

A patient with a history of spontaneous pneumothorax presents for hyperbaric oxygen therapy. Which action is MOST appropriate before initiating treatment?

Accepted Answer

Obtain physician clearance and verify resolution of the pneumothorax

Answer

A history of spontaneous pneumothorax is a relative contraindication; confirmed resolution and physician clearance are required before HBO therapy.

Question 2

During the pre-treatment assessment, a patient reports taking bleomycin. This is significant because bleomycin combined with HBO therapy increases the risk of:

Accepted Answer

Pulmonary fibrosis and oxygen toxicity

Answer

Bleomycin potentiates pulmonary oxygen toxicity, and HBO therapy in patients who have received bleomycin can precipitate severe pulmonary fibrosis.

Question 3

Which vital sign parameter is MOST critical to assess before a patient enters a hyperbaric chamber for wound care treatment?

Accepted Answer

Blood glucose level

Answer

Blood glucose must be checked because HBO therapy lowers blood glucose, and hypoglycemia during a treatment session can be dangerous and difficult to treat inside the chamber.

Question 4

A patient scheduled for hyperbaric therapy reports consuming alcohol within the past 4 hours. The BEST course of action is to:

Accepted Answer

Postpone the treatment session

Answer

Alcohol intoxication is a contraindication to HBO therapy because it increases seizure risk and impairs the patient's ability to equalize ear pressure.

Question 5

When assessing claustrophobia risk before hyperbaric treatment, which assessment tool is MOST commonly used?

Accepted Answer

Modified Claustrophobia Questionnaire (MCQ)

Answer

The Modified Claustrophobia Questionnaire helps screen patients who may have difficulty tolerating enclosed chamber environments.
