1. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

• A. energy
• B. active transport
• C. passive diffusion
• D. osmotic pressure

Correct answer: D

Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

2. Clients with type 2 diabetes are most likely to achieve metabolic control if they:

• A. lose weight
• B. use self-monitoring of blood glucose
• C. eliminate all dietary sugars
• D. eat three regular meals daily

Correct answer: A

Rationale: Weight loss improves insulin sensitivity and glycemic control, making it a key strategy in managing type 2 diabetes.

3. What physiologic role does calcium 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: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

4. A woman who has been following a vegan diet may need ____ supplements.

• A. vitamin C and vitamin A
• B. vitamin D and vitamin B12
• C. vitamin E and K
• D. vitamin D and niacin

Correct answer: B

Rationale: The correct answer is B: vitamin D and vitamin B12. Vegans may need to supplement vitamin D and B12 as these nutrients are mainly found in animal products. While choices A, C, and D are essential vitamins, they are not typically lacking in a vegan diet. Vitamin C can be obtained from various plant sources, vitamin A can be derived from beta-carotene in plants, and vitamin E and K are also found in plant-based foods. Niacin, although important, can be sourced from plant-based sources and is not a common deficiency in vegan diets.

5. A nurse is caring for a client following an appendectomy. The nurse verifies the postoperative prescription which reads, 'Discontinue NPO status; advance diet as tolerated.' Which of the following are appropriate for the nurse to offer the client? (SATA)

• A. Wheat toast
• B. Applesauce
• C. Applesauce, Chicken broth
• D. Chicken broth

Correct answer: C

Rationale: The correct answer is C: Applesauce and chicken broth. After an appendectomy, patients are typically started on a clear liquid diet before advancing to more solid foods. Applesauce and chicken broth are part of a low-residue diet that is easily digestible and gentle on the digestive system, making them suitable choices for a client following surgery. Wheat toast may be too heavy and fibrous initially, while other solid foods should be introduced gradually to prevent gastrointestinal upset.
