Generally, patients who wear dentures have reduced masticatory efficiency. Mandibular implant-supported dentures can have positive effects on the clinical aspects of mastication and swallowing.
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct Answer: A
Rationale: Both statements are true. Patients who wear dentures typically experience reduced masticatory efficiency. Mandibular implant-supported dentures are known to have positive effects on the clinical aspects of mastication and swallowing, significantly improving chewing function. Option A is correct because both statements align with these facts. Option B is incorrect as both statements are true. Option C is incorrect as the second statement is also true. Option D is incorrect as the first statement is true.

Which of the following suggestions is the healthiest for Miguel, who is always hungry and never seems to feel full despite eating enough calories?
- A. Switch out energy-dense foods with more nutrient-dense foods that are more likely to make him feel full
- B. Drink adequate amounts of water
- C. A, B
- D. Eat foods with more fat, as fat slows gastric emptying and will make him feel more full
Correct Answer: C
Rationale: The correct answer is A and B. Switching to more nutrient-dense foods can help Miguel feel full despite eating enough calories. Nutrient-dense foods provide essential nutrients and are more satisfying. Drinking adequate water is also crucial for overall health and can help with feelings of fullness. Choice D is incorrect because while fat can contribute to satiety, it should be consumed in balance with other nutrients. Consuming foods with high fat content excessively may lead to other health issues and does not address the underlying problem of feeling constantly hungry despite eating.
Which practice is a type of traditional Chinese medicine?
- A. magnet therapy
- B. acupuncture
- C. faith healing
- D. biofeedback

_____ 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.
In PEM, which condition is characterized by symptoms such as muscle weakness, hanging skin, delayed tooth eruption, and changes in saliva?
- A. Marasmus
- B. Kwashiorkor
- C. Anemia
- D. Noma
Correct Answer: A
Rationale: The correct answer is Marasmus. Marasmus is a severe form of protein-energy malnutrition (PEM) that leads to muscle wasting, hanging skin, delayed growth, and changes in saliva. These symptoms are commonly seen in vulnerable populations such as children, homeless individuals, older adults, and substance abusers. Kwashiorkor, on the other hand, is characterized by edema, a distended belly, and skin lesions. Anemia is a condition characterized by a low red blood cell count, leading to fatigue and weakness. Noma is a severe infection affecting the face, particularly the mouth and jaw area.
High blood pressure is defined as systolic and diastolic measurements greater than or equal to:
- A. 140 mm Hg and 90 mm Hg, respectively
- B. 150 mm Hg and 80 mm Hg, respectively
- C. 160 mm Hg and 110 mm Hg, respectively
- D. 180 mm Hg and 120 mm Hg, respectively
Correct Answer: A
Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.
