1. Which is NOT a characteristic or function of lipids?
- A. Involved in energy metabolism and storage
- B. Provide insulation and protection
- C. Act as hormones that regulate the body
- D. Are hydrophilic
Correct answer: D
Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.
2. In the hospital, when you need the medical record of a discharged patient for research you will request permission through:
- A. Doctor in charge
- B. The hospital director
- C. The nursing service
- D. Medical records section
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
3. What stimulates bile secretion from the liver to the small intestine?
- A. Pepsin
- B. Salivary Amylase
- C. CCK
- D. Secretin
Correct answer: C
Rationale: Cholecystokinin (CCK) is the hormone that stimulates the release of bile from the gallbladder into the small intestine, aiding in fat digestion. Pepsin is an enzyme in the stomach that breaks down proteins into smaller peptides, not involved in bile secretion. Salivary Amylase is an enzyme in saliva that initiates starch digestion in the mouth, not related to bile secretion. Secretin is a hormone that regulates the release of gastric juice in the stomach and triggers the pancreas to neutralize stomach acid in the small intestine, but it does not stimulate bile secretion.
4. Does the hypothalamus control the feeling of hunger and satiety, and are fats the best nutrient in creating the feeling of satiety?
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: A
Rationale: Yes, the hypothalamus plays a crucial role in regulating hunger and satiety. Fats are indeed known to be highly satiating nutrients, helping to create a feeling of fullness and satisfaction after a meal. Therefore, both statements are true. Choice B is incorrect because fats are indeed effective in promoting satiety.
5. Which enzyme initiates protein digestion in the stomach?
- A. Pepsin
- B. Salivary Amylase
- C. CCK
- D. Secretin
Correct answer: A
Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.
