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. A nurse is assessing a client who has malnutrition. Which of the following findings should the nurse expect?

• A. Increased vital capacity
• B. Dry skin
• C. Heat intolerance
• D. Decreased mental status

Correct answer: D

Rationale: Malnutrition can lead to a variety of physical and mental symptoms. One common manifestation of malnutrition is a decreased mental status, which includes confusion, lethargy, and cognitive impairment. Dry skin is a typical finding in malnutrition due to the lack of essential nutrients needed for skin health. Heat intolerance is not a direct consequence of malnutrition. While malnutrition can affect respiratory function, it typically leads to decreased vital capacity rather than increased. Therefore, the correct answer is decreased mental status.

3. A nurse is teaching about nutrition to a client who has a new diagnosis of chronic kidney disease. Which of the following recommendations should the nurse include in the teaching?

• A. Increase phosphorus intake
• B. Limit calcium intake
• C. Limit protein intake
• D. Increase potassium intake

Correct answer: C

Rationale: The correct recommendation for a client with chronic kidney disease is to limit protein intake. Excessive protein consumption can strain the kidneys as they work to eliminate waste products from protein metabolism. This can worsen kidney function in individuals with chronic kidney disease. Therefore, limiting protein intake is crucial in managing this condition. Choices A, B, and D are incorrect. Increasing phosphorus intake can be harmful in kidney disease as it can lead to mineral imbalances. Limiting calcium intake is not typically necessary unless the client has specific complications. Increasing potassium intake may also be inappropriate as potassium levels can be affected in kidney disease.

4. For an incontinent elderly client who frequently wets his bed and develops redness and skin excoriation at the perianal area, what is the best nursing goal?

• A. Ensure that the bed linen is always dry
• B. Frequently check the bed for wetness and keep it dry
• C. Place a rubber sheet under the client's buttocks
• D. Keep the patient clean and dry

Correct answer: A

Rationale: The best nursing goal for an incontinent elderly client with skin excoriation is to ensure that the bed linen is always dry. This helps in preventing further skin breakdown and promoting skin integrity. Choice B, to frequently check the bed for wetness and keep it dry, may not address the issue of prevention if the linen is not consistently dry. Choice C, placing a rubber sheet under the client's buttocks, focuses more on protecting the mattress rather than addressing the client's skin condition directly. Choice D, keeping the patient clean and dry, is important but does not specifically address the preventive aspect of maintaining dry bed linen.

5. What special consideration should be taken into account when Mario prepares Richard for postural drainage and percussion?

• A. Monitoring a respiratory rate of 16 to 20 per minute
• B. Assessing the client's ability to tolerate sitting and lying positions
• C. Ensuring the client is free of signs of infection
• D. Knowing the time of the client's last food and fluid intake

Correct answer: A

Rationale: The correct answer is A, 'Monitoring a respiratory rate of 16 to 20 per minute'. When performing postural drainage and percussion, it is crucial to monitor the respiratory rate to ensure the safety and effectiveness of the procedure. Choice B, 'Assessing the client's ability to tolerate sitting and lying positions', while important, is not directly related to the specifics of postural drainage and percussion. Similarly, option C, 'Ensuring the client is free of signs of infection', although important, is not directly linked to the procedure. Option D, 'Knowing the time of the client's last food and fluid intake', might be relevant for other procedures, but it is not the primary consideration for postural drainage and percussion.
