Which foods help improve body defenses and potentially prevent diseases?

Correct Answer: A

Rationale: The correct answer is A because broccoli, oranges, and dark greens are rich in essential nutrients like vitamin C, antioxidants, and phytochemicals that boost the immune system and help prevent diseases. Broccoli contains sulforaphane, which has been shown to have anti-cancer properties. Oranges are high in vitamin C, crucial for immune function. Dark greens like spinach and kale are packed with vitamins and minerals that support overall health. Choice B is incorrect because no single food can cure many diseases. Choice C is incorrect because relying solely on vitamin pills may not provide all the necessary nutrients and benefits of whole foods. Choice D is incorrect as there is no scientific evidence supporting the concept of balancing body molecules through food.

Correct Answer: A

Rationale: The correct answer is A because the amount of alcohol that is safe during pregnancy is unknown. It is recommended to avoid alcohol completely to prevent any potential harm to the developing fetus. B is incorrect because there is no known safe level of alcohol consumption during pregnancy. C is incorrect as any amount of alcohol can potentially harm the fetus. D is incorrect as using alcohol to relax during pregnancy is not recommended due to the associated risks.

Correct Answer: B

Rationale: Mammography is used to detect tumors in the breast tissue by taking X-ray images. Tumors can be cancerous or benign, making early detection crucial for treatment. Pain (A) is a symptom, not detected by mammography. Edema (C) is swelling caused by fluid retention, not a primary target of mammography. Epilepsy (D) is a neurological disorder, unrelated to mammography's purpose. Therefore, the correct answer is B.

Correct Answer: B

Rationale: The correct answer is B: Hamburgers. Clients with hypercholesterolemia should decrease their intake of saturated fats and cholesterol. Hamburgers are typically high in saturated fats and cholesterol due to the ground beef patty and cheese. Broiled catfish (A) is a lean protein source and can be a healthier option. Wheat bread (C) is a good source of fiber and can help lower cholesterol levels. Fresh apples (D) are a healthy choice low in saturated fats and cholesterol. Therefore, hamburgers should be decreased in the diet to manage hypercholesterolemia effectively.

Correct Answer: A

Rationale: The correct answer is A: Administer fluids. In hypovolemic shock, the primary issue is a lack of circulating blood volume. Administering fluids helps to restore blood volume and improve perfusion to vital organs, addressing the underlying cause of shock. Vasopressors (B) are used in distributive shock, sodium bicarbonate (C) is used for metabolic acidosis, and corticosteroids (D) are typically not indicated in hypovolemic shock. Administering fluids is the most important intervention to stabilize the client's condition in hypovolemic shock.
