A patient undergoing hyperbaric oxygen therapy for carbon monoxide poisoning suddenly becomes agitated and confused inside the chamber. The FIRST priority is to:
Answer: Initiate emergency decompression and remove the patient
Neurological deterioration may signal oxygen toxicity or worsening CO toxicity requiring immediate controlled decompression and patient removal for evaluation.
When performing a neurological baseline assessment before HBO treatment for arterial gas embolism, the technician should document which of the following?
Answer: Pupil size and reactivity, motor strength, and level of consciousness
A thorough neurological baseline including pupils, motor function, and consciousness level allows tracking of treatment response in AGE patients.
A patient with an implanted pacemaker presents for HBO therapy. The technician should FIRST:
Answer: Verify that the pacemaker model is rated as pressure-stable and consult cardiology
Most modern pacemakers are pressure-stable, but specific model verification and cardiologist clearance are required before HBO treatment.
During patient assessment, you note a Braden Scale score of 12. This indicates the patient is at:
Answer: High risk for pressure ulcer development
A Braden Scale score of 12 falls in the high-risk range (≤12), indicating significant susceptibility to pressure injuries relevant to wound care patients.
A patient reports a recent upper respiratory infection with nasal congestion prior to their scheduled HBO session. The technician should be MOST concerned about:
Answer: Inability to equalize middle ear and sinus pressure during compression
Nasal congestion impairs Eustachian tube function, making it difficult or impossible to equalize middle ear pressure, increasing barotrauma risk.
Which of the following medications taken by a patient MOST increases the risk of oxygen-induced seizure during HBO therapy?
Answer: Disulfiram (Antabuse)
Disulfiram lowers the seizure threshold and significantly increases the risk of central nervous system oxygen toxicity during HBO treatment.
When assessing a diabetic patient post-HBO treatment, a blood glucose reading of 58 mg/dL is obtained. The MOST appropriate immediate action is:
Answer: Administer oral or IV glucose immediately
A glucose level of 58 mg/dL indicates hypoglycemia requiring immediate glucose administration to prevent neurological complications.
