1. 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.

2. 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.

3. 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 used to manage mucositis in patients receiving chemotherapy. Zinc has been shown to aid in the healing process of mucositis. Vitamin E (Choice A) is not typically used to manage mucositis associated with chemotherapy. Vitamin B12 (Choice B) is essential for nerve function and the formation of red blood cells, but it is not primarily used to manage mucositis. Calcium (Choice D) is important for bone health and nerve function but is not specifically used to manage mucositis.

4. The client diagnosed with acute vein thrombosis is receiving a continuous heparin drip, an intravenous anticoagulant. The health care provider orders warfarin (Coumadin), an oral anticoagulant. Which action should the nurse take?

• A. Discontinue the heparin drip before initiating the Coumadin
• B. Check the client’s INR before beginning Coumadin
• C. Clarify the order with the healthcare provider as soon as possible
• D. Administer the Coumadin along with the heparin drip as ordered

Correct answer: D

Rationale: The correct answer is to administer the Coumadin along with the heparin drip as ordered. Heparin and warfarin are often given together initially because warfarin takes a few days to become effective. Discontinuing the heparin drip before initiating Coumadin can increase the risk of clot formation. Checking the client's INR before starting Coumadin is important but not the immediate action required. Clarifying the order with the healthcare provider is not necessary as both medications are commonly used together.

5. Who typically collects blood specimens?

• A. The nurse
• B. Medical technologist
• C. Physician
• D. Pharmacist

Correct answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician, but the actual collection of specimens is commonly performed by nurses. Physicians are primarily responsible for diagnosing and treating medical conditions rather than collecting blood specimens. Pharmacists are healthcare professionals who specialize in medication management and dispensing, not in collecting blood specimens.
