The nursing instructor teaches the students about selective toxicity when one of the students asks, "What happens when a drug doesn't have selective toxicity?" What is the instructor's best response?
A) Healthy cells are damaged.
B) All pathogens are destroyed in the body.
C) Reduced enzymes are produced.
D) Protein malnutrition
A
Feedback:
When a drug does not display selective toxicity, healthy cells are damaged because the drug does not specifically target only the pathogen. Anti-infectives work by a variety of different means so one drug is not likely to kill every type of pathogen in the body. Selective toxicity does not impact enzyme production or cause protein malnutrition.
