1. A nurse is teaching a client about iron-rich foods. Which food is the best source of heme iron?
- A. Spinach
- B. Lentils
- C. Beef liver
- D. Tofu
Correct answer: C
Rationale: Heme iron, found in animal products like beef liver, is more easily absorbed than non-heme iron from plant sources.
2. Which of the following is a good food source of iodine?
- A. Seafood
- B. Lettuce
- C. Broccoli
- D. Pork
Correct answer: A
Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.
3. Almost all (99%) of the calcium in the body is used for?
- A. regulating the transmission of nerve impulses
- B. providing energy for cells
- C. providing rigidity for the bones
- D. regulating muscle contraction
Correct answer: C
Rationale: The correct answer is C: providing rigidity for the bones. Almost all of the calcium in the body is utilized for maintaining the strength and structure of bones and teeth. Calcium plays a crucial role in skeletal health by providing rigidity and support to the skeletal system. Choices A, B, and D are incorrect because while calcium is essential for various physiological functions like nerve transmission, cell energy production, and muscle contraction, the majority of calcium in the body is primarily allocated for bone health.
4. Which step of the management process is concerned with Policy making and Stating the goals and objective of the institution?
- A. Planning

5. Which enzyme is most essential for hydrolyzing large protein molecules?
- A. Gastric lipase
- B. Pepsin
- C. Mucus
- D. Intrinsic factor
Correct answer: B
Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.
