Nursing Elites

1. 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.

2. Which cells in the islet of the pancreas are responsible for synthesizing insulin?

• A. Alpha cells
• B. Beta cells
• C. Gamma cells
• D. Delta cells

Correct answer: B

Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.

3. Compared to the typical American diet, what does the DASH diet provide more of?

• A. More saturated fats
• B. Fewer whole grains
• C. More fruits and vegetables
• D. Fewer dairy products

Correct answer: C

Rationale: The correct answer is C. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, emphasizes the consumption of fruits and vegetables, which are high in potassium, fiber, and antioxidants. These nutrients help lower blood pressure. Therefore, compared to the typical American diet, the DASH diet provides more fruits and vegetables. Choices A, B, and D are incorrect. The DASH diet doesn't focus on providing more saturated fats or fewer whole grains or dairy products. In fact, it encourages the consumption of whole grains and low-fat dairy products to promote a balanced and healthy diet.

4. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

5. By force of law, therefore, the PRC-Board of Nursing released Resolution No. 14 Series of 1999 entitled: "Adoption of a Nursing Specialty Certification Program and Creation of Nursing Specialty Certification Council." This rule-making power is called:

• A. Quasi-Judicial Power
• B. Regulatory Power
• C. Quasi-Legislative Power
• D. Executive/Promulgating Power

Correct answer: B

Rationale: The correct answer is B: Regulatory Power. Regulatory power involves the authority to create rules and regulations that govern a specific area. In this case, the PRC-Board of Nursing's release of Resolution No. 14 Series of 1999 for the Nursing Specialty Certification Program falls under regulatory power as it establishes guidelines and standards for nursing specialty certification. Choices A, C, and D are incorrect. Quasi-judicial power involves making decisions on rights and obligations, quasi-legislative power involves creating regulations with the force of law, and executive/promulgating power involves enforcing and implementing laws and regulations.
