Correct Answer: A

Rationale: The correct answer is A: Hypertension. The DASH diet is specifically designed to control hypertension by reducing sodium intake, managing blood pressure, and promoting overall cardiovascular health. Choice B, Diabetes mellitus, is managed through monitoring blood sugar levels and a balanced diet rich in whole grains, fruits, and vegetables. Choice C, Parkinson's disease, is a neurological disorder that is not primarily managed through diet modifications. Choice D, Anemia, is a condition characterized by a lack of healthy red blood cells and is typically managed by addressing the underlying cause and sometimes iron supplementation, not by the methods mentioned in the question.

Correct Answer: A

Rationale: Excessive supplementation of calcium and vitamin D beyond the upper intake level is not recommended unless under medical supervision, as it can cause adverse health effects.

Correct Answer: C

Rationale: The correct answer is C: vomiting. Infants breastfed by mothers who smoke are more likely to experience vomiting and gastrointestinal issues due to the transfer of nicotine and other harmful substances through breast milk. Choices A, B, and D are incorrect. Poor temperature regulation, vision impairment, and elevated blood pressure are not the primary outcomes closely associated with breastfeeding infants of mothers who smoke.

Correct Answer: B

Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.

Correct Answer: A

Rationale: Both statements are true. Patients who wear dentures typically experience reduced masticatory efficiency.

Option A is correct because both statements align with these facts. Option B is incorrect as both statements are true. Option C is incorrect as the second statement is also true. Option D is incorrect as the first statement is true.
