Question 2

Which monitoring parameter is MOST critical to assess for a patient with a history of chronic obstructive pulmonary disease (COPD) during HBO therapy?

Accepted Answer

Respiratory rate and oxygen saturation

Answer

COPD patients may have hypoxic drive and are at risk for respiratory complications, making respiratory rate and SpO2 critical monitoring parameters.

Question 3

A multiplace hyperbaric chamber is pressurized to 2.4 ATA. A patient complains of severe ear pain during compression. What is the correct response?

Accepted Answer

Halt compression, decompress slowly to a depth where pain resolves, then attempt re-compression more slowly

Answer

Halting compression and slowly decompressing until pain resolves allows the patient to equilibrate before attempting further compression at a slower rate.

Question 4

Answer

A tender is a trained attendant who accompanies patients inside the multiplace chamber to provide direct hands-on care.
