Nursing Elites

1. You are teaching students about how hyperosmotic agents (osmotic diuretics) are used to treat intracranial pressure. Which of the following is NOT one of the functions of hyperosmotic agents?

• A. Reduces brain metabolism and systemic blood pressure
• B. Reduces cerebral edema
• C. Dehydrates the brain
• D. Draws fluids from extravascular spaces into the plasma

Correct answer: A

Rationale: Hyperosmotic agents primarily work by reducing cerebral edema, dehydrating the brain, and drawing fluids from extravascular spaces into the plasma. However, they do not have a direct effect on reducing brain metabolism or systemic blood pressure. Therefore, the correct answer is A. Choice B is correct as hyperosmotic agents do help in reducing cerebral edema. Choice C is accurate as hyperosmotic agents dehydrate the brain. Choice D is also true as these agents draw fluids from extravascular spaces into the plasma.

2. The nurse is assisting the recreational director of a long-term care facility in planning outdoor activities for the wheelchair-bound older residents who are mentally alert. Which activity meets the physical and social needs of these residents?

• A. An open-air concert
• B. A tea party in the courtyard
• C. A team ring-toss competition
• D. A picnic in the park

Correct answer: B

Rationale: A tea party in the courtyard provides a social and physical activity suitable for wheelchair-bound older residents who are mentally alert. It offers an opportunity for social interaction, enjoyment of the outdoors, and participation in a physical activity without the need for extensive mobility. An open-air concert may not provide the same level of social interaction or physical engagement as a tea party. A team ring-toss competition may be physically challenging for wheelchair-bound residents. A picnic in the park could present challenges related to accessibility and might not foster the same level of social interaction as a tea party in a more contained courtyard setting.

3. What is the function of the enzyme lactase in the digestive system?

• A. Breaks down lactose into glucose and galactose
• B. Breaks down proteins into amino acids
• C. Converts starch into maltose
• D. Breaks down fats into fatty acids

Correct answer: A

Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.

4. Which task could the nurse safely delegate to the UAP?

• A. Oral feeding of a two-year-old child after application of a hip spica cast
• B. Assessment of the placement and patency of an NG tube
• C. Participation in staff rounds to record notes regarding client goals
• D. Evaluation of a client's incisional pain following narcotic administration

Correct answer: A

Rationale: The correct answer is A because oral feeding of a stable child is a task that can be safely delegated to a UAP. This task does not require nursing assessment or clinical judgment. Choice B involves assessment, which requires the nurse's clinical judgment. Choice C involves recording client goals during staff rounds, which may require interpretation and understanding of the goals set. Choice D involves evaluating a client's pain following medication administration, which requires assessment and clinical judgment by a nurse.

5. The PN and UAP enter a client's room and find the client lying on the bed. The PN determines that the client is unresponsive. Which instruction should the PN give the UAP first?

• A. Obtain emergency help
• B. Feel for a carotid pulse
• C. Bring a glucometer to the room
• D. Check the blood pressure

Correct answer: A

Rationale: The correct answer is to instruct the UAP to obtain emergency help first. When a client is unresponsive, it could indicate a life-threatening condition that requires immediate intervention. Ensuring emergency help is on the way is the priority to address the potentially critical situation. Feeling for a carotid pulse, bringing a glucometer, or checking the blood pressure are important assessments but should come after taking steps to secure immediate assistance.
