Nursing Elites

1. In patients receiving chemotherapy, which nutrient is often supplemented to manage mucositis?

• A. Vitamin E
• B. Vitamin B12
• C. Zinc
• D. Calcium

Correct answer: C

Rationale: Zinc supplementation is often recommended to manage mucositis in patients undergoing chemotherapy. Zinc plays a crucial role in wound healing and immune function, which can help alleviate the symptoms of mucositis. Vitamin E (Choice A) is known for its antioxidant properties but is not typically used to manage mucositis. Vitamin B12 (Choice B) is important for red blood cell production and nerve function but is not directly associated with mucositis management. Calcium (Choice D) is essential for bone health and muscle function but is not a primary nutrient supplemented to manage mucositis.

2. During a synchronized cardioversion on a client in atrial fibrillation, when the machine is activated and there is a pause, what action should the nurse take?

• A. Wait until the machine discharges
• B. Shout “all clear” and don’t touch the bed
• C. Make sure the client is all right
• D. Increase the joules and re-discharge

Correct answer: B

Rationale: The correct action for the nurse to take when there is a pause after activating the machine for synchronized cardioversion on a client in atrial fibrillation is to shout “all clear” and not touch the bed. This step is crucial to ensure the safety of everyone present by warning them that the machine will discharge, preventing anyone from being inadvertently shocked. Waiting for the machine to discharge (choice A) is not recommended as it can lead to accidental injury. While ensuring the client is all right (choice C) is important, the immediate focus should be on safety during the procedure. Increasing the joules and re-discharging (choice D) without assessing the situation can pose risks to the client and the healthcare team.

3. What is the best position to measure the leg circumference of a client with bipedal edema?

• A. Dorsal recumbent
• B. Sitting
• C. Standing
• D. Supine

Correct answer: A

Rationale: When measuring the leg circumference of a client with bipedal edema, the best position to ensure accurate and consistent measurements is the dorsal recumbent position. This position allows the legs to be comfortably positioned, with the individual lying on their back and legs extended. This facilitates accurate measurement of the circumference without the influence of gravity. Sitting and standing positions may not provide optimal conditions for accurate leg circumference measurements as they may not allow the legs to be fully extended. The supine position, although similar to dorsal recumbent, may not provide the same level of comfort and accuracy in leg circumference measurement for a client with bipedal edema.

4. Which of the following is a process of heat loss that involves the transfer of heat from one surface to another?

• A. Radiation
• B. Conduction
• C. Convection
• D. Evaporation

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Radiation (Choice A) is the transfer of heat through electromagnetic waves, while convection (Choice C) is the transfer of heat through the movement of fluids. Evaporation (Choice D) is a cooling process that involves the phase change of a liquid into a gas.

5. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.
