1. Individuals who use antiretroviral drugs frequently develop insulin resistance and _____.
- A. hypertension
- B. hypothyroidism
- C. hyperlipidemia
- D. fluid retention
Correct answer: C
Rationale: The correct answer is C: hyperlipidemia. Antiretroviral drugs can often lead to elevated lipid levels (hyperlipidemia), which is a common side effect of this therapy. This increase in lipids can contribute to cardiovascular risk. Hypertension (choice A) is not typically associated with antiretroviral drug use. Hypothyroidism (choice B) and fluid retention (choice D) are also not commonly linked to antiretroviral therapy.
2. Which foods are the biggest contributors of saturated fats consumed by Americans?
- A. Butter, coconut, and palm oils
- B. Corn oil
- C. Meat and milk
- D. Cheese, pizza, desserts, and chicken
Correct answer: D
Rationale: The correct answer is D: Cheese, pizza, desserts, and chicken. These foods are significant contributors to the intake of saturated fats in the American diet, often found in processed and fast foods. Choices A, B, and C are incorrect because while butter, coconut, and palm oils (A) are sources of saturated fats, they are not the biggest contributors in the American diet. Corn oil (B) is a source of unsaturated fats, and meat and milk (C) contain saturated fats but are not the primary contributors compared to cheese, pizza, desserts, and chicken.
3. Digestible carbs are absorbed as ___ through the small intestinal wall and are delivered to the liver, which releases ___ into the bloodstream.
- A. glucose
- B. monosaccharides
- C. galactose
- D. disaccharides
Correct answer: B
Rationale: Digestible carbohydrates are absorbed as monosaccharides (simple sugars) like glucose, which the liver can release into the bloodstream for energy.
4. Each statement is true of calcium within saliva, except one. Which is the exception?
- A. Saliva is supersaturated with calcium.
- B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
- C. Calcium and phosphate in saliva provide a buffering action.
- D. Calcium within saliva increases dental caries.
Correct answer: D
Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.
5. Myxedema coma is a life-threatening complication of long-standing and untreated hypothyroidism with one of the following characteristics.
- A. Hyperglycemia
- B. Hypothermia
- C. Hyperthermia
- D. Hypoglycemia
Correct answer: A
Rationale: Myxedema coma is associated with hypothermia, not hyperthermia. Therefore, the correct characteristic of myxedema coma is hypothermia. This condition is a medical emergency that requires prompt recognition and intervention to prevent serious complications. The presence of hyperglycemia is not a defining characteristic of myxedema coma, making choice A the correct answer in this case. Hyperthermia and hypoglycemia are not typically seen in myxedema coma and are not consistent with the clinical presentation of this condition.
