1. Which biomolecule is responsible for the storage and transfer of genetic information?
- A. Carbohydrates
- B. Proteins
- C. Lipids
- D. Nucleic acids
Correct answer: D
Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
2. What is the function of the gallbladder?
- A. to store bile
- B. to produce bile
- C. to digest bile
- D. to modify bile to a liquid form
Correct answer: A
Rationale: The correct answer is A: "to store bile." The gallbladder acts as a reservoir for bile produced by the liver. It releases bile into the small intestine to aid in the digestion of fats. Choice B is incorrect because the liver produces bile, not the gallbladder. Choice C is incorrect as the gallbladder does not digest bile but stores and releases it for digestion. Choice D is incorrect because bile is already in liquid form; the gallbladder does not modify it to a liquid state.
3. A nurse is instructing the mother of a toddler who has iron-deficiency anemia to increase iron in the child’s diet in addition to the prescribed iron supplement. Which of the following foods should the nurse recommend?
- A. Skim milk
- B. Bananas
- C. Tuna fish
- D. Cucumbers
Correct answer: Tuna fish
Rationale: Tuna fish is a good source of iron and would be beneficial for a toddler with iron-deficiency anemia. Skim milk, bananas, and cucumbers are not significant sources of iron and would not help in increasing the iron levels in the child's diet. Skim milk, in particular, can inhibit iron absorption due to its calcium content, which is important for the nurse to educate the mother about.
4. Which of the following ethical principles refers to the duty to do good?
- A. Beneficence
- B. Fidelity
- C. Veracity
- D. Nonmaleficence
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. During an initial visit with an older adult client living alone and having difficulty preparing meals, what should the home health nurse do first?
- A. Discuss nutritional requirements with the client.
- B. Refer the client to a senior citizen center.
- C. Arrange for a home-delivered meal program.
- D. Perform a nutrition screening.
Correct answer: D
Rationale: Performing a nutrition screening is the most appropriate action for the nurse to take first. This allows the nurse to assess the client's current nutritional status and identify any specific needs. Discussing nutritional requirements with the client (Choice A) may be important but should come after the initial assessment. Referring the client to a senior citizen center (Choice B) or arranging for a home-delivered meal program (Choice C) are actions that may be considered later based on the findings of the nutrition screening.
