CHS Pharmacology & Medication Management 2

Question 1

Which medication class is contraindicated in hyperbaric oxygen therapy due to its ability to lower the seizure threshold in an oxygen-enriched environment?

Accepted Answer

Fluoroquinolone antibiotics

Answer

Fluoroquinolones lower the seizure threshold and should be withheld before HBO sessions due to increased CNS oxygen toxicity risk.

Question 2

Disulfiram (Antabuse) is a concern in HBO therapy primarily because it:

Accepted Answer

Inhibits superoxide dismutase and worsens oxidative stress

Answer

Disulfiram inhibits superoxide dismutase, impairing the patient's ability to detoxify reactive oxygen species generated during HBO therapy.

Question 3

A patient on insulin pump therapy is scheduled for HBO. What is the recommended management of the insulin pump during treatment?

Accepted Answer

Suspend the pump and remove it from the chamber

Answer

Insulin pumps contain electronic components and gas-filled reservoirs that are incompatible with hyperbaric pressure and must be removed before chamber entry.

Question 4

Cisplatin (a chemotherapy agent) in combination with HBO therapy primarily raises concern for:

Accepted Answer

Enhanced pulmonary oxygen toxicity

Answer

Cisplatin sensitizes lung tissue to oxygen toxicity, increasing the risk of pulmonary oxygen toxicity when combined with HBO therapy.

Question 5

Which topical agent is absolutely prohibited inside a hyperbaric chamber due to fire hazard?

Accepted Answer

Petroleum-based ointments

Answer

Petroleum-based products are highly flammable and absolutely contraindicated inside hyperbaric chambers because oxygen-enriched environments dramatically lower ignition thresholds.
