The greatest benefit derived from current work being done related to pharmacogenetics is that:
- A. The cost of medication manufacturing will be drastically reduced.
- B. Research and development of new drugs will be much less costly.
- C. Medications will be designed so that they do not cause unwanted side effects.
- D. Medications will be formulated so that only one dose per day will be required.
Correct Answer: C
Rationale: The correct answer is C because pharmacogenetics allows medications to be designed based on an individual's genetic makeup, minimizing unwanted side effects. This is beneficial as it enhances treatment effectiveness and safety. Choice A is incorrect as cost reduction in manufacturing is not the primary focus of pharmacogenetics. Choice B is incorrect as research and development costs are not directly impacted by pharmacogenetics. Choice D is incorrect as the frequency of medication dosing is not the main benefit derived from pharmacogenetics.

A patient who has HIV asks the nurse why blood work has to be done so frequently. Which response should the nurse make to the patient?
- A. B-lymphocyte levels increase if you have an acute infection.'
- B. Phagocytes are decreased when the disease is in an active phase.'
- C. Neutrophil counts help the doctor titrate medication levels to keep you healthy.'
- D. CD4+ lymphocyte counts are monitored to determine the progression of the disease.'
Correct Answer: D
Rationale: The correct answer is D because monitoring CD4+ lymphocyte counts is crucial in managing HIV. CD4+ cells are the primary target of the HIV virus, and their count reflects the status of the immune system and disease progression. By tracking CD4+ levels, healthcare providers can determine the need for antiretroviral therapy and assess the effectiveness of treatment.
Choice A is incorrect because B-lymphocytes are not typically used to monitor HIV progression. Choice B is incorrect as phagocytes are not specifically related to HIV disease progression. Choice C is incorrect as neutrophils are not the primary indicator for managing HIV.

- C. Chronic confusion related to degenerative changes in brain tissue as evidenced by nighttime wandering
- D. Insomnia related to sleep disruptions associated with cognitive impairment as evidenced by wandering at night

The nurse is caring for the newborn of a mother who is HIV positive. What treatment should the nurse expect to be prescribed for the infant?
- A. Bacitracin
- B. Erythromycin
- C. Protease inhibitor
- D. Zidovudine (AZT)
Correct Answer: D
Rationale: The correct answer is D: Zidovudine (AZT). This antiretroviral medication is commonly used to prevent transmission of HIV from mother to child during pregnancy and delivery. AZT reduces the risk of vertical transmission by inhibiting viral replication in the newborn. Bacitracin (A) and Erythromycin (B) are antibiotics that do not treat HIV. Protease inhibitors (C) are not typically used in newborns due to safety concerns and efficacy in preventing transmission.
