Washing hands for 2 minutes is recommended at the beginning of a shift to ensure comprehensive removal of any contaminants present on the hands.

Correct Answer is B

Explanation

Choice A rationale

Interferons are proteins produced by cells in response to viral infections and are part of the body's immune response, but they are not directly involved in the engulfing of pathogens.

Choice B rationale

Phagocytosis is the process by which certain cells, such as macrophages and neutrophils, engulf and destroy pathogens. This is a crucial mechanism of the innate immune system.

Choice C rationale

Creating antibodies is the function of B cells in the adaptive immune system, which works alongside phagocytosis but is not the same process.

Choice D rationale

Phagocytosis itself does not stimulate the body to make more white blood cells, but it is a function performed by existing white blood cells to eliminate pathogens.

A. Decrease organisms on the patient's body but take care not to use it around the patient's eyes or in the mouth. B. Thoroughly clean and rinse all soap off the equipment before disinfecting it. C. Sterilize instruments with a bacteriostatic disinfectant. D. First remove all organic matter prior to disinfecting.

Correct Answer is D

Explanation

Choice A rationale

Disinfectants are not intended for use on the patient's body. Using them around the eyes or mouth can cause irritation or harm, as they are designed to kill or inhibit the growth of microorganisms on inanimate objects.

Choice B rationale

It is important to thoroughly clean and rinse all soap off equipment before disinfecting, as organic matter and soap residues can interfere with the disinfectant's effectiveness. Proper cleaning removes debris that can protect microorganisms from the disinfectant.

Choice C rationale

Disinfectants cannot sterilize instruments as sterilization refers to the complete elimination of all forms of microbial life, including spores. Bacteriostatic disinfectants only inhibit bacterial growth and do not achieve sterilization.

Choice D rationale

Removing organic matter prior to disinfecting is crucial because organic material can protect microorganisms from the disinfectant, reducing its effectiveness. Proper cleaning ensures that the disinfectant can directly contact and eliminate the microorganisms.
