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. Which vitamin is essential for proper blood clotting?

A. Vitamin A
B. Vitamin E
C. Vitamin K
D. Vitamin C

Correct answer: C

Rationale: Vitamin K is vital for the synthesis of clotting factors, which are necessary for proper blood clotting. Vitamin A (Choice A) is important for vision and skin health, not blood clotting. Vitamin E (Choice B) is an antioxidant that helps protect cells from damage but is not directly involved in blood clotting. Vitamin C (Choice D) is essential for collagen synthesis and a healthy immune system, but it does not play a direct role in blood clotting.

3. You are taking care of critically ill client and the doctor in charge calls to order a DNR (do not resuscitate) for the client. Which of the following is the appropriate action when getting DNR order over the phone?

A. Have the registered nurse, family spokesperson, nurse supervisor and doctor sign
B. Have 2 nurse validate the phone order, both nurses sign the order and the doctor should sign his order within 24
C. Have the registered nurse, family and doctor sign the order
D. Have 1 nurse take the order and sign it and have the doctor sign it within 24 hours

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.

4. The preferred route of administration of medication in the most acute care situations is which of the following routes?

A. Intravenous C. Subcutaneous
B. Epidural D. Intramuscular
C.
D.

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.

5. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

A. Spinach
B. Cantaloupe
C. Chicken
D. Lentils

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.
