Question 2 of 5

What is the definition of selective toxicity in relation to anti-infectives?

A. The ability of an anti-infective completely eliminate all microorganisms from the host's body.B. The ability of an article to the host while targeting microorganisms.C. The ability of an anti-infective to kill or inhibit the growth of microorganisms without causing harm to the hostD. The ability of an anti-infective to target specific microorganisms without affecting other microorganisms

Correct Answer: C

Rationale: Selective toxicity allows anti-infectives to target pathogens while minimizing harm to the host, a key principle for safe and effective antimicrobial therapy.

Question 3 of 5

Which of the following best describes pharmacokinetics?

A. The study of how drugs interact with specific drugB. The study of how drugs are developed and manufacturedC. The study of how drugs are prescribed and administeredD. The study of how drugs are absorbed, distributed, metabolized, and excreted by the body.

Question 5 of 5

What is the definition of pharmacodynamics?

A. The study of how drugs are formulated into different dosage forms.B. The study of how drugs are absorbed, distributed, metabolized, and eliminated in the body.C. The study of how drugs interact with specific drug receptors to produce a physiological response.D. The study of how drugs are developed and tested for safety and efficacy

Correct Answer: C

Rationale: Pharmacodynamics examines how drugs interact with receptors to produce effects, explaining the mechanism behind a drug's physiological response.
