1. When evaluating the success of adding raltegravir to the drug regimen of a 42-year-old female patient with HIV, which laboratory value should the nurse prioritize?

Correct answer: C

Rationale: The correct answer is C: The patient's viral load. In HIV management, monitoring the viral load is crucial to assess the effectiveness of antiretroviral therapy. A decrease in viral load indicates the treatment's success in controlling the HIV infection. Choices A, B, and D are less relevant in this context. C-reactive protein levels and erythrocyte sedimentation rate are markers of inflammation and non-specific indicators of infection, not specifically for HIV. CD4 count is important but not as immediate for evaluating the response to the newly added medication compared to monitoring the viral load.

2. Which of the following are normal arterial blood gas values?

Correct answer: C

Rationale: The correct answer is C: PH 7.40, PaCO2 40 mm Hg, PaO2 90 mm Hg, HCO3 24 mEq/L. These values represent a balanced state for arterial blood gas. Choice A has lower than normal PH and HCO3 levels and higher PaCO2 and lower PaO2 levels. Choice B has higher than normal PH and HCO3 levels, lower PaCO2, and a normal PaO2 level. Choice D has a significantly lower PH and PaO2 level, normal HCO3 level, and low PaCO2 level, indicating an acidic state with impaired oxygenation.

3. Muscular dystrophy is a result of an abnormality of the muscle protein:

Correct answer: B

Rationale: Muscular dystrophy is primarily caused by mutations in the gene that provides instructions for making the protein dystrophin. Dystrophin plays a crucial role in maintaining the structure of muscle fibers. Glycoprotein is a general term for proteins with sugar molecules attached, not specifically related to muscular dystrophy. Troponin is a protein involved in muscle contraction regulation, and actinomyosin is not a specific muscle protein but a complex formed during muscle contraction. Therefore, the correct answer is dystrophin.

4. A patient who was frequently homeless over the past several years has begun a drug regimen consisting solely of isoniazid (INH). What is this patient's most likely diagnosis?

Correct answer: A

Rationale: The correct answer is A: Active tuberculosis. Given the patient's history of homelessness and initiation of isoniazid (INH) treatment, the most likely diagnosis is active tuberculosis. Isoniazid is a first-line medication used in the treatment of active tuberculosis. Latent tuberculosis (choice B) would not typically necessitate treatment with isoniazid alone. Mycobacterium avium complex (choice C) is not typically treated with isoniazid alone. Human immunodeficiency virus (choice D) is a risk factor for developing tuberculosis but is not the primary diagnosis in this patient scenario.

5. A nurse is administering testosterone to a patient with hypogonadism. What outcome indicates that the treatment is having the desired effect?

Correct answer: C

Rationale: The correct answer is C: 'Improved secondary sexual characteristics.' Testosterone therapy in patients with hypogonadism typically leads to improved secondary sexual characteristics, which include increased muscle mass and libido. While increased libido (choice A) and increased muscle mass (choice B) are effects of testosterone therapy, they are more specific outcomes related to secondary sexual characteristics. Decreased sperm count (choice D) would not be an expected outcome of testosterone therapy for hypogonadism, as testosterone is essential for sperm production.
