Correct Answer: B

Rationale: The correct answer is B because the internal mammary and internal thoracic arteries in the chest are commonly used for grafting due to their size, durability, and long-term patency. These arteries have a better track record for successful grafting procedures compared to the other options. The basic and cephalic veins in the arm (Option A) are typically used for venous procedures, not arterial grafting. The saphenous vein in the leg (Option C) is also commonly used for grafting, but the internal mammary and internal thoracic arteries are preferred for their better outcomes. The radial artery in the arm (Option D) is less commonly used for grafting compared to the internal mammary and internal thoracic arteries.

Correct Answer: D

Rationale: The correct answer is D: high calorie high protein. In COPD exacerbation, the body requires extra calories and protein for energy and muscle strength. High-calorie foods help combat weight loss and fatigue. High-protein foods aid in muscle repair and maintenance. Low-fat low-cholesterol (A) is not ideal as healthy fats are needed. Low-sodium (B) is not necessary unless there is concurrent heart failure. Bland soft diet (C) is not suitable as it does not provide enough calories and protein needed for COPD exacerbation.

Correct Answer: D

Rationale: The correct answer is D: “You must avoid hyperextending your neck after surgery.” This is because hyperextending the neck can put excessive strain on the surgical site, leading to potential complications such as bleeding or injury to the incision. Keeping the neck in a neutral position helps promote healing and reduces the risk of complications. A: “The head of your bed must remain flat for 24 hours after surgery.” - Incorrect. Elevating the head of the bed can help reduce swelling and promote drainage after thyroidectomy. B: “You should avoid deep breathing and coughing after surgery.” - Incorrect. Deep breathing and coughing are important to prevent respiratory complications such as pneumonia. C: “You won’t be able to swallow for the first day or two.” - Incorrect. Swallowing may be difficult initially but should improve gradually after surgery.

Correct Answer: A

Rationale: The correct answer is A because it meets the goal of maintaining a heart rate of 78 beats/min. This specific date ensures the consistency of the heart rate within the desired range. Choices B, C, and D do not align with the goal as they either have a different heart rate or occur on a different date. Therefore, A is the only option that accurately reflects the goal being met on the specified date.

Correct Answer: C

Rationale: The correct answer is C: Lean red meats. Lean red meats are a rich source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Heme iron helps improve iron levels more effectively in individuals with iron deficiency anemia. Fresh fruits (A) and dairy products (B) contain minimal iron, while breads and cereals (D) provide non-heme iron which is not as readily absorbed.
