Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.

Correct Answer: D

Rationale: All the listed options (Age, Sleep, Fasting/Starvation, Activity Level) are factors that can affect a person's Basal Metabolic Rate (BMR). BMR is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions. Age can affect BMR as metabolism slows with age. Sleep can influence BMR as metabolism slows during sleep. Fasting or starvation can decrease BMR as the body conserves energy. Activity level can also influence BMR; the more active you are, the higher your BMR, as your body requires more energy for physical activities.

Correct Answer: A

Rationale: The primary goal of a dental hygienist when making dietary recommendations for a patient with a new dental prosthesis is to promote healing and repair. This can be achieved by ensuring the patient maintains an adequate and nutrient-dense diet. This is why option 'A' is the correct answer. Option 'B' is incorrect because while liquids are easier to consume with a new dental prosthesis, a diet consisting only of liquids for a week may not provide all necessary nutrients. Option 'C' is incorrect because while a variety of fibrous foods can contribute to a healthy diet, it's not specifically relevant to the healing and adjustment to a new dental prosthesis. Option 'D' is incorrect because eating as usual may not be feasible or comfortable for a patient with a new prosthesis, and it doesn't specifically focus on promoting healing and repair.

Correct Answer: D

Rationale: Carbohydrates, fats, and proteins are the three macronutrients that provide energy (calories) to the body. Carbohydrates are the body's primary source of energy, fats act as a secondary source when carbohydrate energy is exhausted, and proteins are used for energy when carbohydrate and fat sources are low. Choice D, Water, is essential for the body's functions, but it does not provide energy.
