1. Which chemical structure is represented by glycerol combined with two fatty acids?

• A. Compound lipids
• B. Monoglycerides
• C. Diglycerides
• D. Structural lipids

Correct answer: C

Rationale: The correct answer is C: Diglycerides. A diglyceride is a glycerol molecule combined with two fatty acids. This is a common form of fat during digestion and absorption. Choice A, Compound lipids, is incorrect because these lipids are composed of simple lipids plus additional compounds, which is not the case with a glycerol molecule combined with two fatty acids. Choice B, Monoglycerides, is incorrect because these are glycerol molecules combined with only one fatty acid, not two. Lastly, choice D, Structural lipids, is incorrect because these are major components of cell membranes and do not directly relate to the combination of glycerol and two fatty acids.

2. 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.

3. Each of the following is a function of the liver except one. Which one is the exception?

• A. Regulatory control of nutrients in the bloodstream
• B. Conversion of monosaccharides to triglycerides
• C. Breakdown of polysaccharide glycogen into glucose
• D. Oxidation of digestive end products to provide energy

Correct answer: B

Rationale: The correct answer is B. The liver does not convert monosaccharides to triglycerides; instead, it converts monosaccharides to glucose or glycogen. Choice A is correct because the liver plays a role in regulating the levels of various nutrients in the bloodstream. Choice C is correct as the liver breaks down stored glycogen into glucose to maintain blood sugar levels. Choice D is correct as the liver oxidizes digestive end products to provide energy. Therefore, only choice B is incorrect as the liver does not convert monosaccharides to triglycerides.

4. When should a newborn transition to whole milk according to dietary teaching for breastfeeding parents?

• A. 6 months
• B. 8 months
• C. 10 months
• D. 12 months

Correct answer: D

Rationale: Breast milk or formula should be the primary source of nutrition for infants up to around 1 year of age. The transition to whole cow's milk is recommended at 12 months of age, not earlier. Introducing whole milk before 12 months can lead to digestive issues and nutrient deficiencies. Therefore, choices A, B, and C are incorrect as they suggest transitioning to whole milk before the recommended age of 12 months.

5. The nurse understands that one of these factors contributes to constipation:

• A. excessive exercise
• B. high fiber diet
• C. no regular time for defecation daily
• D. prolonged use of laxatives

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.
