_________ supply the body with energy and provide needed fiber.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Carbohydrates are the body's primary source of energy. 2. They are broken down into glucose for immediate energy or stored as glycogen for later use. 3. Carbohydrates also provide fiber for digestive health. 4. Fats are primarily for energy storage, not immediate energy. 5. Proteins are essential for building and repairing tissues, not primarily for energy. 6. Vitamins are micronutrients that do not provide energy. In summary, carbohydrates are the correct answer as they are the main energy source and provide fiber, while fats, proteins, and vitamins have different primary functions.

Correct Answer: D

Rationale: Step-by-step rationale for why Trichomoniasis (D) is the correct answer: 1. Trichomoniasis is a sexually-transmitted infection caused by the parasite Trichomonas vaginalis. 2. Symptoms can include itching, swollen genitals, and vaginal bleeding. 3. Gonorrhea (A) typically presents with discharge and painful urination, not itching and swelling. 4. Vaginitis (B) is a general term for inflammation of the vagina and may not specifically include these symptoms. 5. Chlamydia (C) commonly causes discharge and pain, but not necessarily itching and swelling. Summary: Trichomoniasis is the correct answer as it matches the symptoms provided, while the other choices do not fully align with the symptoms described.

Correct Answer: C

Rationale: The correct answer is C: Taking diuretics to reduce fluid volume. Diuretics help lower blood pressure by reducing the volume of fluid in the body, which decreases the workload on the heart and blood vessels. This effectively reduces blood pressure. Choices A, B, and D are incorrect as reducing exercise, increasing fat in the diet, and increasing weight can all contribute to hypertension rather than treat it.

Correct Answer: B

Rationale: The correct answer is B: Bursae. Bursae are small sacs filled with fluid that help reduce friction between bones, muscles, and tendons near joints. They act as cushions and lubricate the joint, aiding in smooth movement. Tendonitis (A) is inflammation of a tendon, not fluid-filled sacs. Sepsis (C) is a severe infection in the bloodstream, not related to joint structures. Phlebitis (D) is inflammation of a vein, not associated with joint sacs. Therefore, Bursae is the correct answer.

Correct Answer: C

Rationale: The correct answer is C: Hemianopsia. "Hemi" means half, and "anopsia" means blindness. Therefore, hemianopsia refers to the loss of vision in half of the visual field. Hyperopia (A) is farsightedness, myopia (B) is nearsightedness, and macular degeneration (D) is a condition affecting the macula in the retina, not specifically related to loss of vision in half of the visual field.
