1. Plant stanols and sterols help to lower LDL cholesterol and are often added to which food product?

• A. margarine
• B. milk
• C. cereal
• D. yogurt

Correct answer: A

Rationale: Plant stanols and sterols are commonly added to margarine to help lower LDL cholesterol levels. Margarine acts as a vehicle for these compounds, making it easier for individuals to incorporate them into their daily diet. While milk, cereal, and yogurt are healthy food options, they are not typically enriched with plant stanols and sterols for cholesterol-lowering purposes, making them less likely candidates as the correct answer.

2. Reducing the amount of trans fat in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a source of trans fat?

• A. hot dogs
• B. whole milk
• C. fatty fish
• D. potato chips

Correct answer: D

Rationale: The correct answer is D: potato chips. Potato chips, especially when fried in hydrogenated oils, are a common source of trans fats, which are linked to an increased risk of coronary heart disease (CHD). Hot dogs (choice A) can also contain trans fats if made with processed meats and added fats. Whole milk (choice B) and fatty fish (choice C) do not typically contain trans fats, making them less likely sources compared to potato chips.

3. Which enzyme is most essential for the digestion of triglycerides found in butterfat?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: A

Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.

4. What is the most effective way to limit the number of microorganisms in the hospital?

• A. Using strict aseptic technique in all procedures
• B. Wearing a mask and gown when caring for all patients with communicable diseases
• C. Sterilizing all instruments
• D. Handwashing

Correct answer: A

Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.

5. Amy is a 68-year-old patient who has rheumatoid arthritis affecting her hands and feet. Which substance has been shown to reduce joint tenderness and improve mobility in some people with this type of arthritis?

• A. Alfalfa Tea
• B. Cod Liver Oil
• C. Lecithin
• D. Fish Oil

Correct answer: D

Rationale: Fish oil has been identified as a substance that can help reduce joint tenderness and improve mobility in individuals with rheumatoid arthritis, as it is rich in omega-3 fatty acids. Omega-3 fatty acids have anti-inflammatory properties that can help alleviate the symptoms of rheumatoid arthritis. On the other hand, while Alfalfa Tea, Cod Liver Oil, and Lecithin have various health benefits, there isn't substantial evidence to suggest that they can improve conditions associated with rheumatoid arthritis.
