1. What is the purpose of the cuff in a Tracheostomy tube?
- A. Separate the upper and lower airway
- B. Separate trachea from the esophagus
- C. Separate the larynx from the nasopharynx
- D. Secure the placement of the tube
Correct answer: B
Rationale: The purpose of the cuff in a Tracheostomy tube is to separate the trachea from the esophagus. The cuff helps prevent aspiration by creating a seal that separates the trachea from the esophagus, reducing the risk of food or fluids entering the lungs. Choices A, C, and D are incorrect because the cuff's primary function in a Tracheostomy tube is to prevent aspiration rather than separating the upper and lower airway, larynx from the nasopharynx, or securing the placement of the tube.

3. Which of the following has the greatest effect on an increase in body weight?
- A. Carbohydrate intake
- B. Protein intake
- C. Fat intake
- D. Total kilocalories
Correct answer: D
Rationale: Total kilocalories have the greatest effect on body weight as they represent the overall energy intake from all macronutrients combined. While the consumption of specific macronutrients like carbohydrates, proteins, and fats can affect weight management, the total calories consumed play the most significant role in determining body weight. Therefore, choices A, B, and C are incorrect as they focus on individual macronutrients rather than the overall energy balance provided by total kilocalories.
4. What are the best food sources of magnesium?
- A. oils, bananas, and pork
- B. pizza, potatoes, and tomatoes
- C. milk, rice, and apples
- D. legumes, whole grains, and chocolate
Correct answer: D
Rationale: The correct answer is D: legumes, whole grains, and chocolate. These foods are rich sources of magnesium, an essential mineral that plays a role in over 300 biochemical reactions in the body. Choices A, B, and C do not contain as high levels of magnesium compared to legumes, whole grains, and chocolate.
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.
