Nursing Elites

1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: high HDL cholesterol

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. After undergoing gastric resection, the client is informed by the nurse that which of the following meals is most likely to cause rapid emptying of the stomach?

• A. a high-protein meal
• B. a high-fat meal
• C. a large meal regardless of nutrient content
• D. a high-carbohydrate meal

Correct answer: a high-carbohydrate meal

Rationale: After gastric resection, meals high in carbohydrates are more likely to cause rapid emptying of the stomach. Carbohydrates stimulate the release of gastrin, which accelerates gastric emptying. On the other hand, high-fat and high-protein meals tend to delay gastric emptying. A large meal, regardless of nutrient content, can also delay gastric emptying due to the increased volume of food that needs to be processed.

3. In an emergency situation, the nurse determines whether a client has an airway obstruction. Which of the following does the nurse assess?

• A. ability to speak
• B. ability to hear
• C. oxygen saturation
• D. adventitious breath sounds

Correct answer: ability to speak

Rationale: In an emergency situation, assessing the client's ability to speak is crucial in determining airway obstruction. If a client can speak, it indicates that the airway is patent and not completely obstructed. Choices B and C, assessing the ability to hear and oxygen saturation, are not directly indicative of an airway obstruction. Choice D, adventitious breath sounds, may be present in conditions like asthma or pneumonia but are not specific to determining an airway obstruction.

4. How many feet should separate the nurse and the source when extinguishing a small, wastebasket fire with an appropriate extinguisher?

• A. 1 foot
• B. 2 feet
• C. 4 feet
• D. 6 feet

Correct answer: D

Rationale: The nurse should stand about 6 feet from the source of the fire. Getting closer might put the nurse in danger. Choice A, 1 foot, is incorrect because it is too close to the fire and can expose the nurse to unnecessary risk. Choice B, 2 feet, is also too close to the fire and may lead to potential harm. Similarly, choice C, 4 feet, is not the ideal distance as it is still within the range of potential danger. The correct answer is D, 6 feet, which is a safe distance for the nurse to extinguish the fire effectively without risking personal safety.

5. A client has been placed in isolation because he is diagnosed with a contagious illness. The nurse should be aware that:

• A. Linens from the client’s bed should be double-bagged.
• B. Meals should be served on washable dishes.
• C. Extensive isolation rarely causes psychological problems.
• D. Paper trays and plastic utensils do not prevent disease transmission.

Correct answer: Linens from the client’s bed should be double-bagged.

Rationale: Isolation techniques are used to prevent or limit the spread of infection. Special handling of articles and linens soiled by any body fluid is essential. Linens should be placed in impervious bags before being removed from the client’s bedside to prevent exposure of personnel and contamination of the environment. Double-bagging is required if the outside of the bag becomes contaminated. This practice ensures that potentially infectious materials are properly contained and disposed of. Choices B, C, and D are incorrect because the focus in this scenario is on proper handling and disposal of soiled linens to prevent the spread of infection, not on serving meals, psychological effects of isolation, or the use of paper trays and plastic utensils.
