Nursing Elites

1. Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?

• A. They have a high energy-to-fluid-volume ratio.
• B. Even though hypertonic, they are well tolerated.
• C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
• D. The pH is alkaline, making them compatible with most medications.

Correct answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

2. The licensed practical nurse is observing a graduate nurse as she assesses the central venous pressure. Which observation would indicate that the graduate needs further teaching?

• A. The graduate places the client in a supine position to read the manometer.
• B. The graduate turns the stop-cock to the off position from the IV fluid to the client.
• C. The graduate instructs the client to perform the Valsalva maneuver during the CVP reading.
• D. The graduate notes the level at the top of the meniscus.

Correct answer: C

Rationale: The correct answer is C because the client should breathe normally during a central venous pressure monitor reading. Placing the client in a supine position (Choice A) is correct if the client can tolerate it. Turning the stop-cock off (Choice B) and noting the level at the top of the meniscus (Choice D) are also correct actions during CVP monitoring. Instructing the client to perform the Valsalva maneuver is incorrect as it can artificially alter the CVP reading, indicating a need for further teaching.

3. A 25-year-old male is brought to the emergency room with a piece of metal in his eye. Which action by the nurse is correct?

• A. Use a magnet to remove the object.
• B. Rinse the eye thoroughly with saline.
• C. Cover both eyes with paper cups.
• D. Administer eye drops immediately.

Correct answer: C

Rationale: Covering both eyes with paper cups is the correct action as it helps prevent consensual movement of the affected eye. Attempting to remove the object with a magnet might cause trauma, making choice A incorrect. While rinsing the eye with saline may be necessary, it should be ordered by a doctor and is not the initial action for the nurse, making choice B incorrect. Administering eye drops immediately, as in choice D, is not appropriate in this scenario and does not address the primary concern of preventing further damage by limiting eye movement.

4. James returns home from school angry and upset because his teacher gave him a low grade on an assignment. After returning home from school, he kicks the dog. This coping mechanism is known as:

• A. denial
• B. suppression
• C. displacement
• D. fantasy

Correct answer: C

Rationale: The correct answer is 'displacement.' Displacement is a defense mechanism where emotions or impulses are transferred from their original source to a substitute target. In this scenario, James is displacing his anger from his teacher onto the dog. Choice A, 'denial,' involves refusing to acknowledge an unpleasant reality. Choice B, 'suppression,' is the conscious effort to push unwanted thoughts out of awareness. Choice D, 'fantasy,' refers to imagining scenarios that fulfill one's desires but are not based in reality.

5. A 24-year-old female client is scheduled for surgery in the morning. What is the primary responsibility of the nurse?

• A. Taking the vital signs
• B. Obtaining the permit
• C. Explaining the procedure
• D. Checking the lab work

Correct answer: A

Rationale: The primary responsibility of the nurse is to take the vital signs before any surgery. This action helps assess the client's baseline condition and identify any abnormalities that need addressing before the procedure. Obtaining the permit (choice B) is typically handled by administrative staff, explaining the procedure (choice C) is usually done by the healthcare provider performing the surgery, and checking the lab work (choice D) is often part of the pre-operative assessment conducted by the healthcare provider. Therefore, in this context, these actions are not the primary responsibility of the nurse.
