Nursing Process Practice Questions

Correct Answer: B

Rationale: The correct answer is B: Focus on the patient's presenting situation. In the problem-oriented approach, the nurse starts by identifying the patient's main issue or reason for seeking care. This step helps prioritize data collection and guides further assessment and intervention. By focusing on the presenting situation, the nurse can gather relevant information efficiently and address the immediate concern. Incorrect choices: A: Completing questions in chronological order may not be the most effective approach as it does not prioritize the patient's current problem. C: Making accurate interpretations of data comes after data collection and analysis, not as the first step. D: Conducting an observational overview is important, but it should come after focusing on the patient's presenting situation to gather targeted data.

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: 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: A

Rationale: The correct answer is A: circulating nurse. The circulating nurse is responsible for maintaining cleanliness, ensuring proper temperature, humidity, and lighting in the operating room. They coordinate activities, manage supplies, and ensure a safe environment for the surgical team. The scrub nurse assists the surgeon with instruments and supplies, not environmental conditions. The surgeon's main focus is on performing the surgery, not environmental management. The anesthesiologist is responsible for administering anesthesia and monitoring the patient's vital signs, not the operating room environment.

Correct Answer: C

Rationale: Rationale: 1. Abdominal injection sites have a higher blood supply, leading to faster absorption. 2. Insulin absorption is faster in areas with more blood vessels. 3. Rapid absorption at the abdomen results in quicker onset of action. 4. Other sites may have slower absorption due to less blood flow. Summary: A: Incorrect. Absorption is faster at abdominal sites due to increased blood flow. B: Incorrect. Absorption varies based on injection site blood supply. C: Correct. Abdominal injection sites have rapid insulin absorption. D: Incorrect. Insulin absorption is consistent based on blood flow at injection sites.
