Show answer
✓ Correct answer: Nitrous oxide poisoning; move the technician to fresh air, provide supportive respiratory care including oxygen if necessary, and monitor vital signs.
Correct Answer: Nitrous oxide poisoning; move the technician to fresh air, provide supportive respiratory care including oxygen if necessary, and monitor vital signs. Nitrous oxide is commonly used in anesthesia but can be hazardous if inhaled in significant amounts. Symptoms of nitrous oxide poisoning include dizziness, nausea, and shortness of breath. Immediate intervention includes moving the affected individual to an area with fresh air, providing supportive care including oxygen, and closely monitoring vital signs. Ongoing training for proper handling of anesthesia gases and PPE usage is essential in preventing such incidents.
Q2Why is it important to conduct a routine inventory check of surgical instruments before starting an ambulatory surgery?
Show answer
✓ Correct answer: To ensure all instruments are accounted for and in proper condition to avoid intraoperative delays or complications
Answer: To ensure all instruments are accounted for and in proper condition to avoid intraoperative delays or complications. Performing a routine inventory check helps verify that no instruments are missing or damaged, which is crucial for smooth operation and patient safety. If any instrument is not functional, timely replacement can be arranged to prevent delays or complications during the surgery.
Q3Based on OSHA guidelines, which type of personal protective equipment (PPE) is recommended for handling hazardous drugs in an ambulatory surgery center?
Show answer
✓ Correct answer: Chemotherapy gloves
Answer: Chemotherapy gloves According to OSHA guidelines, special chemotherapy gloves are recommended for handling hazardous drugs because they provide a higher level of protection against chemical exposure. Surgical masks, face shields, and disposable gowns are also important, but they do not provide the same level of protection for handling hazardous drugs.
Q4During a routine outpatient endoscopy, a nurse accidentally spills a chemical disinfectant on their skin. What should they do first?
Show answer
✓ Correct answer: Rinse the affected area with water
Answer: Rinse the affected area with water The first action to take after coming into contact with a chemical disinfectant is to rinse the skin with water to remove any contaminants. After that, follow the facility’s policy for reporting the incident and seeking medical evaluation if necessary.

Show answer
✓ Correct answer: 46°F
Answer: 46°F Refrigerators used for medication storage should maintain a temperature between 35°F and 46°F (1.7°C to 7.8°C) to ensure medication stability and efficacy. Temperatures above 46°F could compromise the integrity of certain medications. It is important to regularly monitor and document the refrigerator temperature as per facility policy.

Q10A patient with a history of severe allergies, including an allergy to latex, is scheduled for arthroscopic knee surgery at an outpatient clinic. What deviation from the normal preoperative process would you possibly expect as this patient's nurse?
Show answer
✓ Correct answer: The operating room must be specially prepared to be latex-free.
Answer: The operating room must be specially prepared to be latex-free. Patients with a latex allergy can experience severe reactions if exposed to latex products during surgery. All latex-containing items, such as gloves, catheters, and tubing, must be replaced with latex-free alternatives. Additionally, the surgical team and the operating room should be free of latex-containing materials to prevent latex particles in the air, and the patient should be monitored closely for any signs of allergic reactions.
