The nurse identifies which host factor as the most important when choosing an antimicrobial drug?

Age

Competent immune function

Genetic heritage

Previous medication reactions.

Answer and Explanation

The Correct Answer is B

This is because antibiotics act synergistically with the immune system to subdue infection, and it is critical for success that the host defenses are adequate.

Choice A is wrong because Age is wrong because age is a general factor that must be considered when choosing any medication, not just antimicrobials.

Choice C is wrong because Genetic heritage is wrong because genetic heritage is also a general factor that may affect the metabolism and excretion of medications, not the selection of antimicrobials.

Choice D is wrong because Previous medication reactions is wrong because previous medication reactions are also a general factor that may indicate allergies or intolerances to certain medications, not the selection of antimicrobials.

Normal ranges for immune function vary depending on the type and level of immunity measured, such as innate, adaptive, humoral or cellular immunity. Some common tests for immune function include complete blood count (CBC), immunoglobulin levels, complement levels, antibody titers and skin tests.

Normal ranges for these tests depend on the laboratory and the method used, but some examples are:

• CBC: white blood cell count 4.5-11 x 10^9/L; neutrophils 40-75%; lymphocytes 20-50%; monocytes 2-10%; eosinophils 1-6%; basophils 0-2%.

• Immunoglobulin levels: IgG 7-16 g/L; IgA 0.7-4 g/L; IgM 0.4-2.3 g/L; IgE 0-0.4 g/L.

• Complement levels: C3 0.9-1.8 g

Choice B is wrong because metallic taste in mouth is not a side effect of rifampin, but of metronidazole, an antibiotic used to treat infections caused by anaerobic bacteria or protozoa.

Choice C is wrong because photosensitivity reaction is not a side effect of rifampin, but of tetracycline, an antibiotic used to treat acne and other infections.

Choice D is wrong because ototoxicity is not a side effect of rifampin, but of aminoglycosides, a class of antibiotics used to treat serious infections caused by gram-negative bacteria.

Ototoxicity can cause hearing loss or balance problems.

A. Acyclovir B. Oseltamivir C. Efavirenz D. Rilpivirine.

Correct Answer is B

Explanation

Choice A is wrong becauseAcyclovir is wrong because it is anucleoside analogthat inhibits viral DNA synthesis.

It is effective against herpes simplex virus (HSV) and varicella zoster virus (VZV), but not against influenza virus.

Choice C is wrong because Efavirenz is wrong because it is a **non-nucleoside reverse transcript
