1. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

2. Which type of drug is most likely to cause unintentional weight gain?

• A. Antiemetics
• B. Sedatives
• C. Corticosteroids
• D. Antibiotics

Correct answer: C

Rationale: Corticosteroids are most likely to cause unintentional weight gain. They influence the metabolism and fat distribution in the body, leading to weight gain. On the other hand, antiemetics are drugs that are used to prevent nausea and vomiting, and they do not typically cause weight gain. Sedatives, while they can cause drowsiness and may lead to less physical activity, are not directly associated with weight gain. Lastly, antibiotics are used to fight bacteria and while they can cause temporary digestive issues, they do not typically result in long-term weight gain.

3. All of the following are contraindications when giving Immunization except:

• A. BCG Vaccine can be given to a child with AIDS
• B. BCG Vaccine can be given to a child with Hepatitis B
• C. DPT can be given to a child that had convulsion 3 days after being given the first DPT dose
• D. DPT can be given to a child with active convulsion or other neurological disease

Correct answer: B

Rationale: The correct answer is B. BCG vaccine can be given to a child with Hepatitis B, as there is no contraindication for this. Choice A, C, and D all present contraindications for administering immunizations. Choice A is incorrect because giving BCG vaccines to a child with AIDS is a contraindication. Choice C is incorrect as convulsions after the first DPT dose indicate a contraindication to subsequent doses. Choice D is incorrect because active convulsions or other neurological diseases are contraindications to receiving the DPT vaccine.

4. Diseases of the heart and blood vessels are collectively referred to as _____.

• A. Coronary artery disease
• B. Cardiovascular disease
• C. Coronary heart disease
• D. Coronary vessel disease

Correct answer: B

Rationale: The correct term for diseases of the heart and blood vessels is cardiovascular disease. While coronary artery disease (Choice A) specifically involves the narrowing of coronary arteries, it is just one type of cardiovascular disease. Coronary heart disease (Choice C) is also a specific condition related to the heart's blood vessels. Choice D, coronary vessel disease, is not a commonly used term to describe diseases of the heart and blood vessels. Therefore, Choice B, cardiovascular disease, is the most inclusive and appropriate term to refer to these conditions.

5. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
