_________ supply the body with energy and provide needed fiber.

Correct Answer: B

Rationale: Carbohydrates are the correct answer as they are the primary source of energy for the body and provide fiber for digestive health. Fats are also an energy source but are not the main provider. Proteins are important for building and repairing tissues, not primarily for energy. Vitamins are essential for various bodily functions but do not supply energy or fiber.

Correct Answer: D

Rationale: The correct answer is D: Trichomoniasis. This STI is caused by a parasite called Trichomonas vaginalis, not a bacteria like gonorrhea (A) or chlamydia (C). Symptoms include itching and swollen genitals, not vaginal bleeding like in cases of vaginitis (B). Trichomoniasis is commonly associated with these specific symptoms, making it the most appropriate choice.

Correct Answer: C

Rationale: The correct answer is C: Taking diuretics to reduce fluid volume. Diuretics help lower blood pressure by promoting the removal of excess fluid and sodium from the body, reducing the volume of blood flowing through the blood vessels. This decreases the pressure on the vessel walls, thereby reducing hypertension. A: Reducing the amount of exercise is incorrect because exercise is actually beneficial for managing hypertension by improving cardiovascular health and lowering blood pressure. B: Increasing fat in the diet is incorrect as high-fat diets can lead to obesity and other risk factors for hypertension. D: Increasing weight is incorrect as obesity is a known risk factor for hypertension, and weight gain can exacerbate the condition.

Correct Answer: B

Rationale: The correct answer is B: Bursae. Bursae are small sacs filled with synovial fluid near joints that help reduce friction between bones, tendons, and muscles. Tendonitis (A) is inflammation of a tendon, not fluid-filled sacs. Sepsis (C) is a severe infection in the bloodstream, unrelated to joint structures. Phlebitis (D) is inflammation of a vein, not associated with joint fluid sacs. Therefore, Bursae is the only choice that accurately describes the tiny sacs of fluid near joints.

Correct Answer: C

Rationale: The correct answer is C: Hemianopsia. Hemianopsia refers to the loss of vision in half of the visual field, typically caused by damage to the brain's visual pathways. Hyperopia (A) and Myopia (B) are refractive errors affecting visual acuity, not visual field loss. Macular degeneration (D) is a condition affecting central vision, not half of the visual field. Hemianopsia specifically describes the loss of vision in one-half of the visual field due to neurological issues or brain damage.
