ABA Safety and Infection Control 3

Question 1

Which anesthetic agent is CONTRAINDICATED in a patient with known malignant hyperthermia susceptibility?

Accepted Answer

Sevoflurane

Answer

All volatile halogenated anesthetics (including sevoflurane) and succinylcholine are MH triggers and must be avoided in susceptible patients.

Question 2

When a needlestick injury occurs in the OR, what is the FIRST immediate action the exposed healthcare worker should take?

Accepted Answer

Wash the wound thoroughly with soap and water

Answer

Immediate wound washing with soap and water is the first step; reporting and PEP evaluation follow promptly afterward.

Question 3

Which class of pathogens is MOST associated with prion disease transmission and requires specialized decontamination beyond standard sterilization?

Accepted Answer

Prions (misfolded proteins)

Answer

Prions are resistant to conventional sterilization; instruments used in high-risk neurological procedures require specific protocols (e.g., NaOH treatment or prolonged autoclaving).

Question 4

An anesthesiologist accidentally administers a medication intended for another patient due to look-alike/sound-alike vials. Which system-level intervention MOST effectively prevents this error?

Accepted Answer

Standardized color-coded labeling and tall-man lettering on drug vials

Answer

Standardized labeling with tall-man lettering and color coding is a proven human-factors strategy that reduces look-alike/sound-alike medication errors.

Question 5

Which antiseptic is PREFERRED for central venous catheter insertion site preparation due to its superior residual activity?

Accepted Answer

Chlorhexidine gluconate 2% with 70% isopropyl alcohol

Answer

Chlorhexidine-alcohol combination provides rapid kill and prolonged residual antimicrobial activity superior to povidone-iodine for CVC insertion.
