1. Each is a physiologic role of vitamin D, except one. Which is the exception?

• A. Hematopoiesis
• B. Cardiac and neuromuscular function
• C. Immune responses
• D. Serum calcium regulation

Correct answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.

2. A nurse is caring for a client who is well-hydrated and who demonstrates no evidence of anemia. Which of the following laboratory values gives the nurse an assessment of the adequacy of the client's protein uptake and synthesis?

• A. Albumin
• B. Calcium
• C. Sodium
• D. Potassium

Correct answer: A

Rationale: The correct answer is Albumin. Albumin is a protein made by the liver and is a key indicator of the body's protein status. Low levels of albumin can indicate inadequate protein intake or synthesis. Choices B, C, and D (Calcium, Sodium, and Potassium) are not direct indicators of protein uptake and synthesis. Calcium is related to bone health, Sodium to fluid balance, and Potassium to nerve and muscle function.

3. Has Healthy People (HP 2020), issued by the U.S. Department of Health and Human Services, resulted in a reduction of deaths from cardiovascular disease, stroke, and some cancers, as well as decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years?

• A. Yes, both statements are true.
• B. No, both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: B

Rationale: Both statements are false. While Healthy People (HP 2020) has contributed to a reduction in deaths from cardiovascular disease, stroke, and some cancers, it did not result in decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years. Therefore, the correct answer is B. Choice A is incorrect because the second statement is false. Choice C is incorrect as the first statement is also false. Choice D is incorrect as the second statement is false.

4. 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.

5. In PEM, which condition is characterized by symptoms such as muscle weakness, hanging skin, delayed tooth eruption, and changes in saliva?

• A. Marasmus
• B. Kwashiorkor
• C. Anemia
• D. Noma

Correct answer: A

Rationale: The correct answer is Marasmus. Marasmus is a severe form of protein-energy malnutrition (PEM) that leads to muscle wasting, hanging skin, delayed growth, and changes in saliva. These symptoms are commonly seen in vulnerable populations such as children, homeless individuals, older adults, and substance abusers. Kwashiorkor, on the other hand, is characterized by edema, a distended belly, and skin lesions. Anemia is a condition characterized by a low red blood cell count, leading to fatigue and weakness. Noma is a severe infection affecting the face, particularly the mouth and jaw area.
