A client is in the immediate postoperative period following a partial laryngectomy. Which of the following parameters should the nurse assess first?
- A. Pain severity
- B. Wound drainage
- C. Tissue integrity
- D. Airway patency
Correct Answer: D
Rationale: The correct answer is D: Airway patency. Assessing airway patency is the priority in the immediate postoperative period following a laryngectomy to ensure the client's ability to breathe. If the airway is compromised, it can lead to life-threatening complications. Pain severity (A), wound drainage (B), and tissue integrity (C) are important assessments but are secondary to ensuring the client's airway is clear and functioning properly. Prioritizing airway patency allows for prompt intervention if any issues arise, ensuring the client's safety and optimal recovery.
A female postoperative client has returned to the Unit following a pneumonectomy. In assessing the client's incision, twenty-four hours postoperatively, the nurse notices fresh blood on the dressing. The nurse should first:
- A. reinforce the dressing.
- B. continue to monitor the dressing.
- C. notify the physician.
- D. note the time and amount of blood.
Correct Answer: C
Rationale: The dressing should not be reinforced without notifying the physician. The physician may decide to reinforce the dressing after assessing the amount of bleeding. Blood on the dressing is unusual, which should alert the nurse to do more than monitor the dressing. The physician should be notified immediately. If the bleeding persists, the client may need to return to surgery. The time and amount of blood needs to be recorded, but only after the physician is notified.
