Nursing Elites

1. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

• A. reducing cholesterol synthesis
• B. suppressing inflammation
• C. reducing blood clotting
• D. interfering with cholesterol and bile absorption

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

2. The PACU nurse will maintain postoperative T and A client in what position?

• A. Supine with neck hyperextended and supported with pillow
• B. Prone with the head on pillow and turned to the side
• C. Semi-fowler’s with neck flexed
• D. Reverse trendelenburg with extended neck

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. A healthcare professional is preparing to remove a client’s clogged NG tube prior to re-inserting a new tube. Which of the following actions should the healthcare professional take first?

• A. Assist the client in blowing their nose.
• B. Ask the client to take a deep breath and hold it.
• C. Pinch the proximal end of the tube.
• D. Disconnect the tube from the suction source.

Correct answer: D

Rationale: Correct Answer: Disconnecting the tube from the suction source is the first step in safely removing a clogged NG tube. This action helps prevent any suction-related complications and ensures a smooth transition when removing the tube. Choice A, assisting the client to blow their nose, is not necessary in this situation. Choice B, asking the client to take a deep breath and hold it, is unrelated to the process of removing a clogged NG tube. Choice C, pinching the proximal end of the tube, should only be done after disconnecting the tube from the suction source to prevent the contents from leaking.

4. What is a common symptom of vitamin D deficiency?

• A. Hair loss
• B. Night blindness
• C. Bone pain
• D. Rashes

Correct answer: C

Rationale: The correct answer is C: Bone pain. Vitamin D deficiency often leads to bone pain and weakness as it plays a crucial role in maintaining bone health by aiding in the absorption of calcium. Hair loss (choice A) is not a common symptom of vitamin D deficiency. Night blindness (choice B) is typically associated with vitamin A deficiency, not vitamin D deficiency. Rashes (choice D) are not a common symptom of vitamin D deficiency.

5. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.
