1. What physiological role does phosphorus play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

2. Which vitamin's recommended dietary allowance (RDA) is significantly increased during pregnancy?

• A. Folate
• B. Thiamine (B1)
• C. Riboflavin (B2)
• D. Niacin (B3)

Correct answer: A

Rationale: The correct answer is A: Folate. During pregnancy, the recommended dietary allowance (RDA) for folate is significantly increased to support fetal development and prevent neural tube defects and other congenital anomalies. Folate plays a crucial role in DNA synthesis and cell growth, making it essential for the rapidly dividing cells of the developing fetus. Thiamine (B1), Riboflavin (B2), and Niacin (B3) are important vitamins, but their RDAs do not undergo as significant an increase during pregnancy as folate's RDA does.

3. A nurse is caring for a client who is receiving parenteral nutrition. Which of the following findings indicates the therapy is effective?

• A. Client has soft, formed bowel movements.
• B. Client’s mucous membranes are pink.
• C. Client reports ability to complete ADLs.
• D. Client’s blood glucose level is within the expected reference range.

Correct answer: D

Rationale: The correct answer is D because having a blood glucose level within the expected reference range indicates that parenteral nutrition is effectively meeting the client's nutritional needs. Choices A, B, and C are incorrect because soft, formed bowel movements, pink mucous membranes, and the ability to complete activities of daily living do not directly reflect the effectiveness of parenteral nutrition therapy.

4. What is the name of the record that shows all medications and treatments provided on a repeated basis?

• A. Nursing Health History and Assessment Worksheet
• B. Discharge Summary
• C. Nursing Kardex
• D. Medicine and Treatment Record

Correct answer: D

Rationale: The 'Medicine and Treatment Record' is the document that maintains a comprehensive log of all medications and treatments provided on a routine basis. It does not refer to the 'Discharge Summary', which is a clinical report prepared by healthcare professionals at the end of a hospital stay or series of treatments. The 'Nursing Health History and Assessment Worksheet' is used to gather comprehensive data about the patient's health history and current health status, but it does not record ongoing treatment details. The 'Nursing Kardex' is a patient care information system used to quickly communicate patient needs, but it does not consistently record all medications and treatments provided.

5. 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.
