Correct Answer: D

Rationale: The correct answer is D: Contact precautions. When a client has an abdominal wound with purulent drainage, contact precautions are necessary to prevent the spread of infection through direct contact. Protective environment precautions are used for immunocompromised clients, airborne precautions are for diseases transmitted by airborne particles, and droplet precautions are for diseases transmitted by respiratory droplets. In this case, the focus is on preventing direct contact transmission, making contact precautions the most appropriate choice. Protective environment, airborne, and droplet precautions are not indicated in this scenario because the primary concern is the direct contact transmission of pathogens through the wound drainage.

Correct Answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.

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.

Correct Answer: D

Rationale: The correct answer is to include the type of transmission-based precautions in the report. This information is crucial for infection control when caring for a client with shingles, as it helps prevent the spread of the virus to other clients and healthcare workers. Choices A, B, and C are not directly related to managing a client with shingles. Option A about the location of breakfast is irrelevant to the client's condition. Option B about vital sign measurements, though important, is not the priority when discussing a client with shingles. Option C mentions 'specific times the client had visitors,' which is not as crucial as knowing the specific precautions in place to prevent transmission of the virus.

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.
