1. Is the loss of teeth or supporting periodontium often associated with poor food selection and limited chewing ability, and do the patients' masticatory efficiency and biting force decline with each tooth lost?
- 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 indeed true. The loss of teeth or supporting periodontium frequently leads to poor food selection and limited chewing ability, as these conditions can make certain foods difficult to consume. Additionally, a patient's masticatory efficiency and biting force do decline with each tooth lost, as there are fewer teeth to distribute the force of the bite. Choices B, C, and D are incorrect because they suggest that one or both of these statements are false, which is not the case.
2. Which of the following is a factor that affects Basal Metabolic Rate (BMR)?
- A. Age
- B. Sleep
- C. Fasting/Starvation
- D. All of the above
Correct answer: D
Rationale: All the listed options (Age, Sleep, Fasting/Starvation, Activity Level) are factors that can affect a person's Basal Metabolic Rate (BMR). BMR is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions. Age can affect BMR as metabolism slows with age. Sleep can influence BMR as metabolism slows during sleep. Fasting or starvation can decrease BMR as the body conserves energy. Activity level can also influence BMR; the more active you are, the higher your BMR, as your body requires more energy for physical activities.
3. Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: B
Rationale: Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.
4. What sensation is used as a gauge so that patients with ileostomy can determine how often their pouch should be drained?
- A. Sensation of taste
- B. Sensation of pressure
- C. Sensation of smell
- D. Urge to defecate
Correct answer: B
Rationale: The correct answer is B: Sensation of pressure. Patients with ileostomy can determine how often their pouch should be drained by feeling the sensation of pressure. This is important as it helps prevent leakage or overflow of the pouch. The sensation of taste (choice A) and smell (choice C) are not typically used as gauges for draining the pouch in ileostomy patients. The urge to defecate (choice D) is not relevant in this context as patients with ileostomy do not pass stool through the rectum.
5. 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.
