Which factor has been shown to increase the risk of development of atherosclerosis?

Correct Answer: A

Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.

Correct Answer: A

Rationale: Both statements are indeed true. As people age, their taste perception tends to decline. This change can be further exacerbated by the use of multiple medications, which can potentially dull taste sensitivity even more. Consequently, these individuals often need to consume foods with higher levels of sodium and sugar in order to perceive these tastes. Choices B, C, and D are incorrect because they deny either one or both of these established facts.

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: 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: B

Rationale: When the body consumes more energy than it needs, the surplus is stored as fat, regardless of whether the energy source was proteins, fats, alcohol, or carbohydrates. This is why the correct answer is 'Fat'. Other choices are incorrect because, in excess intake situations, the body does not store surplus energy as proteins, carbohydrates, or alcohol.

Correct Answer: D

Rationale: In type 1 diabetes, the body's immune system destroys the beta cells in the pancreas that produce insulin. This leads to an insufficient amount of insulin, which is required to facilitate the transport of glucose into the cells. Consequently, blood glucose levels remain high. The other options are incorrect. Option A is incorrect because urinary excretion of glucose does not directly contribute to blood glucose levels. Option B is incorrect because, while gluconeogenesis does produce glucose, it is not the cause of high glucose levels in type 1 diabetes. Option C is incorrect because absorption efficiency of glucose from the gastrointestinal tract does not affect the amount of insulin available to transport glucose into cells.

Correct Answer: D

Rationale: The first statement is incorrect because dental caries are not solely caused by sucrose. They are the result of a complex interaction of multiple factors, including the type of bacteria in the mouth, the host's diet, oral hygiene, and salivary flow. The second statement is correct as consuming sugar in moderation and limiting the frequency of sugar exposure are indeed effective strategies to prevent dental caries. Therefore, the answer is option D: The first statement is false; the second is true.
