  1. A patient on insulin develops diaphoresis and confusion 45 minutes into a hyperbaric oxygen treatment. The most appropriate first response is:

    Answer: Administer oral glucose and continue treatment if possible

    Hypoglycemia symptoms during HBO should be treated with oral glucose; if the patient recovers, treatment may continue, but ascent is warranted if symptoms worsen.

  2. According to UHMS guidelines, what is the minimum number of treatments typically prescribed for a non-healing diabetic foot wound (Wagner Grade 3)?

    Answer: 30–40 treatments

    UHMS guidelines recommend 30–40 treatments for chronic, non-healing diabetic wounds to achieve meaningful wound closure.

  3. During monoplace chamber operation, chamber pressure is increased to 3.0 ATA too rapidly. The patient complains of severe ear pain. The correct action is:

    Answer: Halt compression, decompress slightly, and allow the patient to equalize

    Stopping compression and slightly reducing pressure gives the patient time to equalize the middle ear before proceeding.

  4. Which treatment table is specifically designed for managing oxygen-breathing divers who surface with decompression sickness symptoms?

    Answer: Table 5

    Table 5 is the shorter U.S. Navy treatment table used for mild DCS in oxygen-breathing divers when symptoms fully resolve at 60 fsw.

  5. Fire prevention protocols in hyperbaric facilities require that oxygen concentration inside a multiplace chamber be maintained below:

    Answer: 23.5%

    NFPA 99 and UHMS standards require ambient oxygen levels inside the chamber to stay below 23.5% to reduce fire risk.

  6. Which of the following best describes the rationale for prescribing hyperbaric oxygen for delayed radiation injury (osteoradionecrosis)?

    Answer: HBO promotes angiogenesis and restores oxygen gradients in hypoxic tissue

    HBO stimulates angiogenesis and fibroblast activity in hypoxic irradiated tissue, restoring the oxygen gradients necessary for healing.

  7. A patient with a history of seizures is scheduled for HBO therapy. Which pretreatment precaution is most important?

    Answer: Ensure antiepileptic medication levels are therapeutic and monitor closely

    Ensuring therapeutic antiepileptic drug levels before HBO reduces the risk of oxygen-triggered seizures in patients with seizure disorders.
