1. Which of the following methods is the best method for determining nasogastric tube placement in the stomach?
- A. X-ray
- B. Observation of gastric aspirate
- C. Testing of pH of gastric aspirate
- D. Placement of external end of tube under water
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
2. 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.
3. A client with cholecystitis is being taught about required dietary modifications. Which of the following foods is appropriate for the client's diet?
- A. Creamed chicken
- B. Roast turkey
- C. Ice cream
- D. Macaroni and cheese
Correct answer: Roast turkey
Rationale: Roast turkey is the most appropriate choice for a client with cholecystitis. Foods that are high in fat content, like creamed chicken, ice cream, and macaroni and cheese, should be avoided in cholecystitis as they can exacerbate symptoms due to the reduced ability of the gallbladder to process fats. Roast turkey is a leaner option that is better tolerated by individuals with cholecystitis.
4. Which food is a high source of prebiotics?
- A. Chicken
- B. Garlic
- C. White rice
- D. Cheese
Correct answer: B
Rationale: Garlic is the correct answer. It is high in prebiotics, which are non-digestible fibers that promote the growth of beneficial gut bacteria. Chicken, white rice, and cheese are not significant sources of prebiotics. Chicken is a good source of protein, white rice is a carbohydrate, and cheese is a dairy product, none of which are high in prebiotics.
5. Which of the following nutrients does not provide energy?
- A. Proteins
- B. Carbohydrates
- C. Fats
- D. Vitamins
Correct answer: D: Vitamins
Rationale: Proteins, carbohydrates, and fats are macronutrients that provide energy in the form of calories when consumed and metabolized by the body. Each gram of protein or carbohydrate provides about 4 calories, and each gram of fat provides about 9 calories. On the other hand, vitamins do not provide energy or calories. They are micronutrients that are essential for various biochemical and physiological processes in the body, including the metabolism of macronutrients. However, they do not contribute directly to the energy supply. Therefore, the correct answer is 'D: Vitamins'. Choices A, B, and C (Proteins, Carbohydrates, and Fats) are incorrect because they are macronutrients that do provide energy/calories when metabolized.
