1. Which mineral-containing amino acids help to form the shape of proteins?

• A. phosphorus
• B. sulfur
• C. selenium
• D. iron

Correct answer: B

Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.

2. Which of the following provides the least amount of potassium?

• A. broccoli
• B. potatoes
• C. bananas
• D. cheese

Correct answer: D

Rationale: Cheese provides less potassium compared to broccoli, potatoes, and bananas, which are all rich in this essential mineral.

3. Why do older adult female clients need less iron than younger adult female clients?

• A. The need for iron decreases because older female clients produce more red blood cells.
• B. The need for iron decreases with age because older female clients carry oxygen more efficiently.
• C. The need for iron decreases with age because older female clients experience menopause.
• D. The need for iron decreases with age because older female clients exercise more.

Correct answer: C

Rationale: The correct answer is C. Older adult female clients need less iron than younger adult female clients because as women go through menopause, they no longer lose blood through menstruation, leading to a reduced need for iron. Choice A is incorrect because producing more red blood cells does not directly correlate with needing less iron. Choice B is incorrect as carrying oxygen more efficiently does not necessarily decrease the need for iron. Choice D is incorrect as exercising more does not explain the decreased need for iron in older adult female clients.

4. Each statement accurately describes the physical effects of food on periodontal health, except one. Which is the exception?

• A. Supragingival plaque biofilm adhesion is influenced by frequent consumption of monosaccharides
• B. Supragingival plaque biofilm adhesion is influenced by frequent consumption of disaccharides
• C. Poor nutrition has an adverse effect on the periodontium
• D. Chewing soft, spongy foods stimulates salivary flow

Correct answer: D

Rationale: The correct answer is D. Chewing soft, spongy foods does not stimulate salivary flow; rather, firm, fibrous foods like fruits and vegetables do. Soft foods can stick to teeth, promoting plaque buildup. Choices A, B, and C are accurate: Supragingival plaque biofilm adhesion is influenced by both monosaccharides and disaccharides, while poor nutrition can indeed have adverse effects on the periodontium.

5. A nurse is caring for four clients. The nurse should plan to administer total parenteral nutrition for which of the following clients?

• A. A client who is postoperative following a laminectomy and is receiving IV PCA
• B. A client who has dysphagia and does not recognize his family
• C. A client who has COPD and is going home with oxygen
• D. A client who has colon cancer and will undergo a hemicolectomy

Correct answer: D

Rationale: Total parenteral nutrition (TPN) is essential for clients undergoing significant surgical procedures like a hemicolectomy to ensure they receive adequate nutrition when oral intake is not possible. Choices A, B, and C do not typically require TPN. Choice A is managing postoperative pain with IV PCA, choice B is likely to need alternative feeding methods due to dysphagia, and choice C is going home with oxygen for COPD management, which does not directly relate to the need for TPN.
