Question

The respiratory therapist is completing oxygen rounds on the ward and checking oxygen saturations on a number of patients. What solution would be most appropriate for disinfecting the surface of the pulse oximeter between patients?

A) 70% ethyl alchohol
B) Warm soapy water
C) Bleach
D) Acid glutaraldehyde

Answer 1

The most appropriate solution for disinfecting the pulse oximeter surface between patients is 70% ethyl alcohol.

Step-by-step explanation:

The most appropriate solution for disinfecting the surface of the pulse oximeter between patients would be 70% ethyl alcohol. Alcohols, such as ethyl alcohol (ethanol) and isopropyl alcohol (isopropanol), work by denaturing proteins and disrupting cell membranes. They are commonly used as disinfectants and antiseptics in healthcare settings. A 70% aqueous solution of ethyl alcohol is typically more effective than 100% alcohol solutions, as it coagulates proteins and allows for better penetration of cells.

Answer 2

70% ethyl alcohol is the most suitable choice for disinfecting a pulse oximeter between patients because it rapidly denatures proteins and disrupts cell membranes, effectively killing bacteria without being too harsh on the skin.

Step-by-step explanation:

The most appropriate solution for disinfecting the surface of the pulse oximeter between patients would be 70% ethyl alcohol. This is because alcohols are effective at denaturing proteins and disrupting cell membranes which are crucial for bacterial survival and can therefore effectively disinfect surfaces. They are frequently used in clinical settings and have the advantage of being less irritating to the skin, compared to other disinfectants like bleach and acid glutaraldehyde, while being more practical than warm soapy water for quick disinfection between uses.
