A break in sterile technique occurs during surgery when the scrub nurse touches
- A. the mask with sterile gloved hands.
- B. sterile gloved hands to the gown at chest level.
- C. the drape at the incision site with sterile gloved hands.
- D. the lower arm to the instruments on the instrument tray.
Correct Answer: A
Rationale: Touching non-sterile items like masks compromises sterility and requires corrective action.
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.
During an assessment, a client with a long history of smoking and suspected laryngeal cancer will most likely report which early manifestation?
- A. Dysphagia
- B. Hoarseness
- C. Dyspnea
- D. Weight loss
Correct Answer: B
Rationale: The correct answer is B: Hoarseness. Hoarseness is a common early manifestation of laryngeal cancer due to vocal cord involvement. Smoking is a major risk factor for laryngeal cancer. Dysphagia (choice A) is more commonly associated with esophageal cancer. Dyspnea (choice C) is usually a late manifestation of laryngeal cancer when it causes airway obstruction. Weight loss (choice D) may occur later in the disease progression but is not typically an early sign. Thus, hoarseness is the most likely early manifestation due to its direct connection to the vocal cords and smoking history.
While caring for a client with extensive partial and full-thickness burns of the head, neck, and chest, which risk should the nurse prioritize for assessment and intervention?
- A. Airway obstruction
- B. Infection
- C. Fluid imbalance
- D. Paralytic ileus
Correct Answer: A
Rationale: The correct answer is A: Airway obstruction. This should be prioritized because burns to the head, neck, and chest can lead to swelling and inflammation, potentially compromising the airway. Maintaining a clear airway is crucial for oxygenation and ventilation. If the airway becomes obstructed, it can quickly lead to respiratory distress or failure. Assessing for signs of airway compromise and intervening promptly is essential to prevent serious complications.
Choices B, C, and D are incorrect because while infection, fluid imbalance, and paralytic ileus are also important considerations in burn care, they are not as immediately life-threatening as airway obstruction in this case. Infection can be managed with appropriate wound care, fluid imbalance can be addressed with fluid resuscitation, and paralytic ileus can be treated with medications and bowel management strategies.
