Nursing Elites

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. How many amino acids are essential?

• A. 5
• B. 7
• C. 9
• D. 13

Correct answer: C

Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.

3. A client with anorexia undergoing radiation therapy is being taught by a nurse. Which instruction should the nurse include in the teaching?

• A. Limit high-calorie supplements to between meals
• B. Avoid overeating during your 'good' days
• C. Eat hot foods instead of cold foods
• D. Consume nutrient-dense foods first

Correct answer: D

Rationale: The correct instruction for a client with anorexia undergoing radiation therapy is to consume nutrient-dense foods first. This ensures that the client receives the necessary calories and nutrients. Option A is incorrect because high-calorie supplements should not be limited but rather incorporated wisely into the diet. Option B is incorrect as overeating is not recommended regardless of the type of day. Option C is incorrect as there is no specific preference for hot foods over cold foods in managing anorexia during radiation therapy.

4. The oral cavity is the site of a wide variety of systemic disease manifestations due to:

• A. Rapid cellular turnover
• B. Constant attack by microorganisms
• C. Trauma-intense environment
• D. All of the above

Correct answer: D

Rationale: The oral cavity is indeed the site of various systemic disease manifestations due to multiple factors. Firstly, the rapid cellular turnover in the oral mucosa makes it susceptible to diseases. Secondly, the constant presence of microorganisms in the oral cavity contributes to the development of systemic diseases. Finally, the oral cavity being a trauma-intense environment further increases the risk of systemic manifestations. Therefore, all the provided options - rapid cellular turnover, constant attack by microorganisms, and a trauma-intense environment - play a role in making the oral cavity a site for various systemic diseases. Hence, the correct answer is 'All of the above.' Choices A, B, and C are incorrect individually as they each represent only one aspect of why the oral cavity is prone to systemic disease manifestations, whereas the correct answer encompasses all these factors.

5. To prevent baby bottle tooth decay, what should the nurse instruct?

• A. Water
• B. Milk
• C. Iron-fortified formula
• D. Unsweetened fruit juice

Correct answer: A

Rationale: The correct answer is A: Water. Water is the best choice to prevent baby bottle tooth decay as it does not cause tooth decay and is a good option for bedtime bottles. Milk (choice B) and iron-fortified formula (choice C) contain sugars that can contribute to tooth decay. Unsweetened fruit juice (choice D) also contains natural sugars that can be harmful to the baby's teeth.
