1. Medications that reduce stomach acidity can impair the absorption of _____.
- A. calcium
- B. iron
- C. vitamin D
- D. vitamin C
Correct answer: B
Rationale: Reduced stomach acidity impairs the absorption of iron, as an acidic environment is necessary for optimal iron absorption in the stomach. Choices A, C, and D are incorrect as medications that reduce stomach acidity typically do not significantly affect the absorption of calcium, vitamin D, or vitamin C.
2. You are an ostomy nurse and you know that colostomy is defined as:
- A. It is an incision into the colon to create an artificial opening to the exterior of the abdomen
- B. It is end to end anastomosis of the gastric stump to the duodenum
- C. It is end to end anastomosis of the gastric stump to the jejunum
- D. It is an incision into the ileum to create an artificial opening to the exterior of the abdomen
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.
3. What is the main function of dietary fiber in managing cholesterol levels?
- A. To reduce absorption of dietary fats
- B. To increase cholesterol synthesis
- C. To enhance protein digestion
- D. To decrease cholesterol absorption
Correct answer: D
Rationale: Dietary fiber helps lower cholesterol levels by binding to bile acids and reducing cholesterol absorption.
4. 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.
5. Based on universally-accepted color codes, what color would you expect a tank containing nitrous oxide (laughing gas) to have?
- A. Red
- B. Blue
- C. Green
- D. Orange
Correct answer: A
Rationale: The correct answer is A: Red. In the medical field, tanks containing nitrous oxide (laughing gas) are typically color-coded with a specific color for easy identification. Nitrous oxide tanks are commonly labeled with a red color code. This color-coding system helps healthcare providers quickly and accurately identify the contents of the tanks, reducing the risk of errors in administering gases to patients. Choices B, C, and D are incorrect because the universally-accepted color for nitrous oxide tanks is red, not blue, green, or orange.
