1. Why are LDLs known as the 'bad' type of cholesterol?

• A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
• 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: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

2. Which symptoms are associated with cancer of the colon?

• A. constipation, ascites, and mucus in the stool
• B. diarrhea, heartburn, and eructation
• C. blood in the stools, anemia, and 'pencil-shaped' stools
• D. anorexia, hematemesis, and increased peristalsis

Correct answer: C

Rationale: The correct symptoms associated with cancer of the colon are blood in the stools, anemia, and 'pencil-shaped' stools. These symptoms are classic indicators of colorectal cancer. Choices A, B, and D do not typically present in colorectal cancer. Constipation, ascites, and mucus in the stool are more commonly associated with other gastrointestinal conditions. Diarrhea, heartburn, and eructation are not typical symptoms of colon cancer. Anorexia, hematemesis, and increased peristalsis are more indicative of other gastrointestinal issues and not specific to colon cancer.

3. 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.

4. Metabolic control is especially important for women with gestational diabetes to ensure the infant does not develop:

• A. microsomia
• B. macrosomia
• C. type 1 diabetes
• D. type 2 diabetes

Correct answer: B

Rationale: Metabolic control is crucial for women with gestational diabetes to prevent the development of macrosomia, which is characterized by an abnormally large baby. This condition poses risks such as birth injuries and necessitates careful management of blood sugar levels. Microsomia is not a known term related to this context. Type 1 and type 2 diabetes are not conditions the infant would develop as a result of gestational diabetes in the mother.

5. What condition has been shown to be associated with esophageal dysphagia?

• A. myasthenia gravis
• B. achalasia
• C. Alzheimer's disease
• D. cerebral palsy

Correct answer: B

Rationale: Achalasia is the correct answer. It is a condition characterized by the esophagus having difficulty moving food toward the stomach, resulting in dysphagia (difficulty swallowing). Myasthenia gravis (Choice A) is a neuromuscular disorder that affects skeletal muscles, not the esophagus. Alzheimer's disease (Choice C) primarily affects cognitive function, not the esophagus. Cerebral palsy (Choice D) is a neurological disorder affecting body movement and muscle coordination, unrelated to esophageal dysphagia.
