1. Health practitioners evaluate disease progression in HIV-infected patients by measuring the concentrations of helper T cells and circulating virus, called _____.

• A. cross resistance
• B. the immune response
• C. acquired resistance
• D. the viral load

2. What are the best food sources of magnesium?

• A. oils, bananas, and pork
• B. pizza, potatoes, and tomatoes
• C. milk, rice, and apples
• D. legumes, whole grains, and chocolate

Correct answer: D

Rationale: The correct answer is D: legumes, whole grains, and chocolate. These foods are rich sources of magnesium, an essential mineral that plays a role in over 300 biochemical reactions in the body. Choices A, B, and C do not contain as high levels of magnesium compared to legumes, whole grains, and chocolate.

3. A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses?

• A. Phosphorus
• B. Calcium
• C. Chloride
• D. Zinc

Correct answer: B

Rationale: Corrected Question: A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses? Correct Answer: Calcium Rationale: Calcium is crucial for nerve transmission, muscle contraction, and blood clotting. It plays a vital role in the proper functioning of the nervous system. Phosphorus is important for bone health and energy metabolism, not nerve impulse transmission. Chloride is an electrolyte important for fluid balance but not directly involved in nerve impulse transmission. Zinc is essential for immune function and wound healing but not specifically required for nerve impulse transmission.

4. Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: B

Rationale: Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.

5. Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: C

Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.
