SterilizationCâu 50 / 100
A technician receives a jar of petroleum-based lubricant and a container of powder that must be sterilized. Which method applies, and what are representative parameters?
a.Flexible endoscopes, at 250 degrees F for 30 minutes
b.Oils, petroleum-based lubricants, and powders, at approximately 320 degrees F for 2 hours or 340 degrees F for 1 hour
c.Rigid containers with filters, at 270 degrees F for 4 minutes
d.Textile packs, at 275 degrees F for 3 minutes
Giải thích
Dry heat is used for anhydrous materials that steam cannot penetrate, such as oils, ointments, and powders, and it needs long exposure at high temperature because heat transfer without moisture is inefficient. Flexible endoscopes are heat sensitive and are high-level disinfected or low-temperature sterilized. The 270 and 275 degrees F short cycles listed are steam parameters, not dry heat.
