Nursing Elites

1. A client who is postoperative following a liver transplant and weighs 65 kg. Which of the following actions should the nurse plan to take?

• A. Keep the client NPO for the first week postoperative.
• B. Limit caloric content once the client resumes eating.
• C. Stress the importance of safe food-handling practices.
• D. Decrease foods high in carbohydrates once the client resumes eating.

Correct answer: C

Rationale: After a liver transplant, it is crucial to stress the importance of safe food-handling practices to prevent foodborne illnesses, especially due to the client's altered immune system. Keeping the client NPO for the first week postoperative is not recommended as early nutrition support is essential for recovery. Limiting caloric content once the client resumes eating may not be appropriate as they need adequate nutrition for healing. Decreasing foods high in carbohydrates without a specific indication may lead to inadequate nutrient intake, which is not ideal for the client's recovery.

2. Each statement is true of vitamin K, except one. Which is the exception?

• A. Vitamin K is produced in the gut.
• B. Vitamin K functions as a catalyst for the synthesis of blood-clotting factors.
• C. Vitamin K maintains prothrombin levels.
• D. Vitamin K absorption increases with high levels of vitamin E supplementation.

Correct answer: D

Rationale: The correct answer is D. Vitamin K absorption decreases with high levels of vitamin E supplementation because in larger amounts, vitamin E acts as an anticoagulant. Vitamin K is not produced in the gut but can be obtained from food sources or supplements. Vitamin K is essential for the synthesis of blood-clotting factors and is crucial in maintaining prothrombin levels, which is vital for proper blood clotting. The incorrect choice, D, is misleading as high levels of vitamin E supplementation hinder vitamin K absorption due to its anticoagulant properties. Dental hygienists should be aware of the importance of vitamin K in blood clotting, especially when treating patients who are on anticoagulant medications for conditions like stroke prevention.

3. List 2 Dispensable amino acids

• A. Alanine
• B. Serine
• C. Glycine
• D. Proline

Correct answer: A

Rationale: Dispensable amino acids, such as alanine and serine, can be synthesized by the body and are not required to be obtained from the diet.

4. An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.

• A. witness
• B. primary caregiver
• C. health care agent
• D. state proxy

Correct answer: C

Rationale: The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.

5. Where in the body are microvilli located, facilitating the absorption of most nutrients?

• A. Stomach
• B. Pancreas
• C. Large Intestine
• D. Small Intestine

Correct answer: D

Rationale: The correct answer is D: Small Intestine. Microvilli are present in the small intestine, significantly increasing its surface area for efficient absorption of nutrients. The small intestine is the primary site for nutrient absorption in the body. The stomach (choice A) primarily functions to break down food with its acidic environment but is not where most nutrients are absorbed. The pancreas (choice B) produces enzymes to aid in digestion but does not directly absorb nutrients. The large intestine (choice C) mainly absorbs water and electrolytes from undigested food, rather than nutrients.
