Correct Answer: B

Rationale: The correct answer is B: 'Describe the pain you are experiencing.' This question is the most effective as it prompts the client to provide detailed information about the nature of the pain, including its characteristics, intensity, and location. This detailed description can help the nurse in assessing the possible cause and severity of the pain. Choices A, C, and D are not as effective as they are either too general ('Tell me how you are feeling right now'), redundant ('Can you tell me more about your back pain?'), or focused only on timing and severity ('When did the pain start and how severe is it?').

Correct Answer: A

Rationale: The correct answer is A: Purulent. Purulent drainage is thick, yellow, and indicates the presence of infection. This type of drainage is typically seen in infected wounds. Choice B, Serous drainage, is thin, clear, and watery, which is normal in the initial stages of wound healing. Sanguineous drainage, choice C, is bright red and indicates fresh bleeding. Serosanguineous drainage, choice D, is pale pink to red and is a mixture of blood and serous fluid commonly seen in the early stages of wound healing.

Correct Answer: B

Rationale: In this scenario, a client who has undergone thoracic surgery and is being admitted from the PACU requires a high level of nursing care. Registered nurses (RNs) have the education and training necessary to provide the complex care and monitoring needed for a post-thoracic surgery client. Charge nurses may oversee units but may not always be directly involved in providing bedside care. Practical nurses (PNs) have a different scope of practice compared to RNs and may not have the advanced skills needed for post-thoracic surgery care. Assistive personnel (AP) provide valuable support but do not have the qualifications to manage the care of a client following thoracic surgery.

Correct Answer: D

Rationale: The absence of breath sounds on the affected side is a critical finding that may indicate a tension pneumothorax, a life-threatening condition requiring immediate intervention. This situation can lead to a shift of the mediastinum and impaired ventilation. Bubbling in the water seal chamber is an expected finding in a chest tube drainage system and indicates proper functioning. Drainage greater than 70 ml/hour is a concern but does not require immediate reporting unless it continues at a high rate or is associated with other symptoms. Tidaling in the water seal chamber is a normal fluctuation and indicates the chest tube system is patent and functioning correctly.

Correct Answer: B

Rationale: Reassessing the client's blood pressure using a larger cuff is the most important action for the nurse to implement in this situation. Using the correct cuff size is crucial for obtaining accurate blood pressure readings. By reassessing with a larger cuff, the nurse can ensure an accurate measurement and proper monitoring of the client's blood pressure. Choice A is not the best option as it doesn't address the immediate need for accurate blood pressure measurement. Choice C is not the most appropriate action at this time since the immediate concern is ensuring correct blood pressure assessment. Choice D, while important, is not the most critical step in this scenario where immediate reassessment is needed with the correct cuff size.
