Nursing Elites

1. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

2. 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.

3. Substance abuse is different from substance dependence in that, substance dependence:

• A. includes characteristics of adverse consequences and repeated use
• B. requires long term treatment in a hospital based program
• C. produces less severe symptoms than that of abuse
• D. includes characteristics of tolerance and withdrawal

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. What is the most significant dietary influence on the development of dental caries?

• A. Carbohydrates
• B. Vitamins
• C. Minerals
• D. Fats

Correct answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.

5. A client receiving total parenteral nutrition (TPN) suddenly develops tremors, dizziness, and diaphoresis. The client said, 'I feel weak and the bag was empty.' Which is the most likely complication the client is currently experiencing?

• A. Fluid volume overload
• B. Sepsis
• C. Hyperglycemia
• D. Hypoglycemia

Correct answer: D

Rationale: The client experiencing tremors, dizziness, diaphoresis, weakness, and stating that the TPN bag is empty is likely experiencing hypoglycemia. Hypoglycemia can occur when the TPN infusion suddenly stops, leading to a rapid drop in blood sugar levels. Symptoms of hypoglycemia include tremors, dizziness, diaphoresis, and weakness. Choices A, B, and C are incorrect as the symptoms presented are more consistent with hypoglycemia rather than fluid volume overload, sepsis, or hyperglycemia.
