1. Which chemical structure is represented by glycerol combined with two fatty acids?

• A. Compound lipids
• B. Monoglycerides
• C. Diglycerides
• D. Structural lipids

Correct answer: C

Rationale: The correct answer is C: Diglycerides. A diglyceride is a glycerol molecule combined with two fatty acids. This is a common form of fat during digestion and absorption. Choice A, Compound lipids, is incorrect because these lipids are composed of simple lipids plus additional compounds, which is not the case with a glycerol molecule combined with two fatty acids. Choice B, Monoglycerides, is incorrect because these are glycerol molecules combined with only one fatty acid, not two. Lastly, choice D, Structural lipids, is incorrect because these are major components of cell membranes and do not directly relate to the combination of glycerol and two fatty acids.

2. A dental hygienist finds several new carious lesions in a patient with chronic obstructive respiratory disease (COPD). While conducting the medical and dental histories, the dental hygienist is most likely to find an increased use of which of the following?

• A. Protein
• B. Cough drops
• C. Fluoride
• D. Xylitol

Correct answer: B

Rationale: The correct answer is B: Cough drops. Patients with COPD often use cough drops to manage their symptoms, which can lead to an increase in carious lesions due to their sugar content. Choices A, C, and D are incorrect as protein, fluoride, and xylitol are not typically associated with an increased risk of carious lesions in patients with COPD.

3. Sucrose is a:

• A. monosaccharide
• B. disaccharide
• C. polysaccharide
• D. starch

Correct answer: B

Rationale: Sucrose is a disaccharide composed of one glucose and one fructose molecule.

4. A nurse is teaching an in-service about manifestations of hypoglycemia to a group of newly licensed nurses. Which of the following should the nurse include in the teaching?

• A. Blurred vision
• B. Vomiting
• C. Kussmaul respirations
• D. Bradycardia

Correct answer: A

Rationale: Corrected Rationale: Blurred vision is a common symptom of hypoglycemia and should be included in the teaching. Other manifestations like vomiting, Kussmaul respirations, and bradycardia are not typically associated with hypoglycemia. Vomiting is more commonly seen in conditions like food poisoning or gastrointestinal issues. Kussmaul respirations are deep and rapid respirations seen in metabolic acidosis, not hypoglycemia. Bradycardia is usually not a manifestation of hypoglycemia; tachycardia is more commonly associated with low blood sugar levels.

5. What is a major feature of the therapeutic lifestyle changes (TLC) recommended for the treatment of high blood cholesterol?

• A. Avoiding all foods that contain cholesterol
• B. Reducing sodium intake to less than 2 g/day
• C. Limiting total fat intake to less than 30% of energy intake
• D. Limiting saturated fat intake to less than 7% of energy intake

Correct answer: D

Rationale: The correct answer is D, 'Limiting saturated fat intake to less than 7% of energy intake.' This is a central feature of the therapeutic lifestyle changes (TLC) recommended for treating high blood cholesterol. Saturated fats can increase low-density lipoprotein (LDL) cholesterol, a significant risk factor for heart disease. Choice A is incorrect because while it is recommended to limit cholesterol intake, it's not suggested to avoid all foods containing cholesterol entirely in the TLC. Choice B is also incorrect as although reducing sodium intake is beneficial for controlling blood pressure, it's not specifically targeted in the TLC for managing high cholesterol. Lastly, while limiting total fat intake is a healthy guideline, it's not as specific or effective as limiting saturated fat intake, making choice C also incorrect.
