Correct Answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy may have other potential benefits, such as improving mood or helping with seasonal affective disorders, the main focus and effectiveness of light therapy are commonly linked to regulating sleep patterns. Therefore, the correct answer is 'Working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not primarily used for overcoming weight problems, helping with allergies, or solely as an alternative medical treatment.

Correct Answer: C

Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. It is calculated by utilizing a chart or nomogram that plots height and weight. This client's BMI is 35, indicating obesity. Choices A, B, and D are incorrect because the client's BMI is above 30, which falls under the obesity category. Therefore, a weight-reduction diet and increased physical activity are necessary to address the client's weight status and promote overall health.

Correct Answer: D

Rationale: All of the above factors are likely to increase the risk of sexually transmitted diseases (STDs). Alcohol use can impair judgment, leading to risky sexual behavior. Certain types of sexual practices, especially unprotected sex or multiple partners, increase the likelihood of contracting STDs. While oral contraception use does not directly increase the risk of STDs, it does not protect against them either. Therefore, all the choices (alcohol use, certain types of sexual practices, and oral contraception use) can contribute to an increased risk of contracting STDs.

Correct Answer: B

Rationale: The correct answer is 'Fever and anemia.' Zidovudine (Retrovir) is known to cause anemia as a side effect due to its impact on the bone marrow. Fever is also a common side effect associated with Zidovudine use. Therefore, the patient should watch out for these specific side effects. Choice A (Weakness and SOB) is incorrect as shortness of breath (SOB) is not a commonly reported side effect of Zidovudine. Choice C (Hypertension and SOB) and Choice D (Fever and hypertension) are unrelated to the known side effects of Zidovudine, making them incorrect.

Correct Answer: B

Rationale: Allopurinol is the correct drug to decrease uric acid levels as it is used to treat gout by reducing uric acid formation. Prednisone is a corticosteroid that decreases inflammation, not uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, not specifically used to reduce uric acid levels. Hydrochlorothiazide is a thiazide diuretic primarily used for treating hypertension and edema, not for reducing uric acid levels.
