1. In managing Type 2 diabetes, what is the most important dietary change?
- A. Increase carbohydrate intake
- B. Increase fiber intake
- C. Increase protein intake
- D. Reduce fat intake
Correct answer: B
Rationale: Increasing fiber intake can help regulate blood sugar levels in patients with Type 2 diabetes.
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. Which mineral is important for the synthesis of thyroid hormones?
- A. Iron
- B. Zinc
- C. Iodine
- D. Magnesium
Correct answer: C
Rationale: Iodine is the correct answer. It is crucial for the synthesis of thyroid hormones by the thyroid gland. Without sufficient iodine, the thyroid cannot produce adequate amounts of hormones, leading to potential issues like hypothyroidism. Iron (Choice A), Zinc (Choice B), and Magnesium (Choice D) do not play a direct role in the synthesis of thyroid hormones, making them incorrect choices for this question.
4. What is the most significant dietary influence on the development of dental caries?
- A. Carbohydrates
- B. Vitamins
- C. Minerals
- D. Fats
Correct answer: A
Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.
5. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?
- A. The body can produce sufficient amounts of vitamin D from sunlight.
- B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
- C. Sunscreen blocks the formation of vitamin D3.
- D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.
Correct answer: C
Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.
