1. Which of the four phases of emergency management is defined as 'sustained action that reduces or eliminates long-term risk to people and property from natural hazards and their effects'?

• A. Recovery
• B. Mitigation
• C. Response
• D. Preparedness

Correct answer: B

Rationale: The correct answer is B, 'Mitigation.' Mitigation is the phase of emergency management that focuses on sustained actions aimed at reducing or eliminating long-term risks to people and property from natural hazards. Recovery (A) involves restoring and rebuilding infrastructure, housing, and services after a disaster. Response (C) deals with immediate actions taken to save lives and prevent further damage during a disaster. Preparedness (D) involves planning, training, and equipping organizations and communities to effectively respond to emergencies.

2. Which risk factors increase the risk of atherosclerosis?

• A. Exercise
• B. Excessive sun exposure
• C. Insufficient vaccinations
• D. Smoking

Correct answer: D

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.

3. Stimulates secretion of bicarbonate ions and digestive enzymes from the pancreas to the small intestine:

• A. pepsin
• B. salivary amylase
• C. CCK
• D. secretin

Correct answer: D

Rationale: Secretin stimulates the pancreas to release bicarbonate ions to neutralize stomach acid and digestive enzymes into the small intestine.

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. Each nonnutritive sweetener can be recommended to patients with phenylketonuria, except one. Which one is the exception?

• A. Cyclamate
• B. Acesulfame-K
• C. Saccharin
• D. Aspartame

Correct answer: D

Rationale: The correct answer is D, Aspartame. Aspartame contains phenylalanine, which is contraindicated for individuals with phenylketonuria (PKU), a genetic disorder that impairs phenylalanine metabolism. Therefore, patients with PKU should avoid aspartame. Choices A, B, and C (Cyclamate, Acesulfame-K, Saccharin) are considered safe for individuals with PKU as they do not contain phenylalanine and can be recommended as alternatives to sugar for these patients.
