1. Protein-energy malnutrition (PEM) may be responsible for the increased incidence of noma and necrotizing ulcerative gingivitis (NUG) because these conditions are associated with depressed immune responses caused by nutritional deficiencies.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: The corrected question highlights that protein-energy malnutrition weakens the immune system, making individuals more susceptible to conditions like noma and NUG, which are linked to compromised immunity. Choice A is correct because the statement and reason are both accurate and directly related. Protein-energy malnutrition does result in depressed immune responses, which can predispose individuals to noma and NUG. Choice B is incorrect because the statement and reason are indeed related. Choice C is incorrect as both the statement and reason are accurate. Choice D is also incorrect as the statement is correct and directly supports the reason provided.

2. 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.

3. Which of the following interventions should be considered the highest priority when caring for June, who has hemiparesis secondary to a stroke?

• A. Position June in an upright lateral position
• B. Perform range of motion exercises
• C. Apply antiembolic stockings
• D. Use hand rolls or pillows for support

Correct answer: C

Rationale: The correct answer is C, 'Apply antiembolic stockings'. In the case of a patient who has experienced a stroke and is suffering from hemiparesis, the highest priority intervention is to prevent further complications such as deep vein thrombosis (DVT), which can be life-threatening. Antiembolic stockings are used to increase venous blood flow velocity and reduce the risk of DVT. Choice 'A', positioning June in an upright lateral position, while important for overall care, is not the highest priority. Choice 'B', performing range of motion exercises, is an important part of recovery but not the immediate priority. Choice 'D', using hand rolls or pillows for support, is also a valuable intervention but does not address the most pressing risk of further complications.

4. Name 4 of the 12 discussed groups at risk for nutritional deficiencies.

• A. Elderly
• B. Low income
• C. Vegans
• D. Chronic disease, alcoholics

Correct answer: A

Rationale: The correct answer is A: Elderly. The other choices provided, low income, vegans, and chronic disease, alcoholics, are also at risk for nutritional deficiencies but the question specifically asks for 4 groups out of the 12 discussed. The 12 groups at risk for nutritional deficiencies include the elderly, low income individuals, vegans, chronic disease, alcoholics, smokers, periods of growth, individuals with medical conditions, physical stress, physiological stress, those on polypharmacy, and those with inadequate intake. The question focuses on identifying 4 out of these 12 groups, making 'Elderly' the correct choice.

5. Each statement is true of vitamin K, except one. Which is the exception?

• A. Vitamin K is produced in the gut.
• B. Vitamin K functions as a catalyst for the synthesis of blood-clotting factors.
• C. Vitamin K maintains prothrombin levels.
• D. Vitamin K absorption increases with high levels of vitamin E supplementation.

Correct answer: D

Rationale: The correct answer is D. Vitamin K absorption decreases with high levels of vitamin E supplementation because in larger amounts, vitamin E acts as an anticoagulant. Vitamin K is not produced in the gut but can be obtained from food sources or supplements. Vitamin K is essential for the synthesis of blood-clotting factors and is crucial in maintaining prothrombin levels, which is vital for proper blood clotting. The incorrect choice, D, is misleading as high levels of vitamin E supplementation hinder vitamin K absorption due to its anticoagulant properties. Dental hygienists should be aware of the importance of vitamin K in blood clotting, especially when treating patients who are on anticoagulant medications for conditions like stroke prevention.
