1. A client is diagnosed with HIV. Which of the following antiviral drug classes are used in the treatment of HIV/AIDS?

A. nucleoside reverse transcriptase inhibitors
B. protease inhibitors
C. HIV fusion inhibitors
D. all of the above

Correct answer: D

Rationale: All of the provided choices are antiviral drug classes used in the treatment of HIV/AIDS. Nucleoside reverse transcriptase inhibitors, such as tenofovir and emtricitabine, work by interfering with the virus's ability to replicate. Protease inhibitors, like atazanavir and darunavir, block an enzyme that HIV needs to make copies of itself. HIV fusion inhibitors, for instance, enfuvirtide, prevent HIV from entering human cells. Therefore, 'all of the above' is the correct answer as all the listed drug classes are commonly used in managing HIV infections. Choices A, B, and C are all essential components of antiretroviral therapy for HIV, targeting different stages of the virus's life cycle. The combination of drugs from these classes is often recommended to effectively control HIV replication and reduce viral load.

2. Which of the following is not an indication for pelvic ultrasonography?

A. to measure uterine size
B. to detect multiple pregnancies
C. to measure renal size
D. to detect foreign bodies

Correct answer: C

Rationale: Pelvic ultrasonography is commonly used to assess various conditions. Choices A, B, and D are all valid reasons for performing pelvic ultrasonography. Measuring uterine size helps evaluate conditions like fibroids, while detecting multiple pregnancies is essential for prenatal care. Furthermore, identifying foreign bodies can aid in diagnosing certain conditions. However, assessing renal size is typically not a primary reason for pelvic ultrasonography, making choice C the correct answer.

3. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

A. high HDL cholesterol
B. low HDL cholesterol
C. low total cholesterol
D. low triglycerides

Correct answer: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.

4. Which of the following is not a function of parathyroid hormone?

A. moving calcium from bones to the bloodstream
B. inhibiting renal tubular reabsorption of phosphorus
C. promoting renal tubular reabsorption of calcium
D. enhancing renal production of vitamin D metabolites

Correct answer: B

Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

5. Which of the following devices may be applicable to a bedridden patient to address potential venous insufficiency?

A. Shear-reducing mattress
B. Sequential compression devices
C. Hiking stockings
D. Non-skid socks

Correct answer: B

Rationale: For a bedridden patient with potential venous insufficiency, sequential compression devices (SCDs) and compression stockings are appropriate choices. SCDs help improve venous return from the lower extremities by applying sequential pressure, aiding circulation. Compression stockings also assist in preventing blood from pooling in the legs by applying pressure to support venous return. Shear-reducing mattresses are not directly related to managing venous insufficiency, as they are designed to reduce friction and shear forces on the skin to prevent pressure ulcers. Non-skid socks are primarily used for fall prevention and have no direct impact on venous insufficiency.
