1. What is a major constituent of cell membranes?
- A. cholesterol
- B. phospholipid
- C. saturated
- D. triglyceride
Correct answer: B
Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.
2. By the age of three, which age-appropriate food skill can a child typically perform?
- A. Using utensils and a napkin
- B. Spearing food with a fork
- C. Measuring liquids
- D. Displaying proper table manners
Correct answer: B
Rationale: By the age of three, a child typically develops the motor skills needed to spear food with a fork. This is a critical milestone in self-feeding as it shows progress in fine motor coordination. Choice 'A' is incorrect because using utensils and a napkin properly is a skill that may take longer to develop and refine. Choice 'C' is not correct as measuring liquids requires a higher level of motor skills and understanding of quantities that a three-year-old child might not possess. Choice 'D' is also incorrect as the proper display of table manners is a complex skill that is typically learned over a longer period and involves social and cultural norms.

- C. Disconnect the drainage bag, obtain a sterile syringe and draw the specimen from the drainage bag
- D. Disconnect the tube, obtain a sterile syringe and draw the specimen from the tube

4. In consideration of the steps in applying the bag technique, which side of the paper lining of the CHN bag is considered clean to make a non-contaminated work area?
- A. The lower lip
- B. The outer surface
- C. The upper tip
- D. The inside surface
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
5. A nurse is instructing a group of clients about nutrition and eating foods high in iron. The nurse should include that which of the following aids in the absorption of iron?
- A. Fiber
- B. Vitamin A
- C. Vitamin C
- D. Oxalates
Correct answer: C
Rationale: Vitamin C aids in the absorption of iron by enhancing the body's ability to absorb non-heme iron, which is found in plant-based foods. This vitamin helps convert iron into a form that is more easily absorbed in the intestines. Choices A, B, and D are incorrect because fiber, Vitamin A, and oxalates can actually inhibit the absorption of iron. Fiber can bind to iron and reduce its absorption, Vitamin A does not directly enhance iron absorption, and oxalates found in some foods like spinach and rhubarb can also hinder iron absorption.
