CAPA Preoperative Evaluation 5 — Questions and Answers
Question 1: A patient discloses a family history of death during general anesthesia in a young relative. Which genetic condition should the perianesthesia nurse MOST suspect?
- G6PD deficiency
- Malignant hyperthermia susceptibility (Correct answer)
- Pseudocholinesterase deficiency
- Porphyria
Correct answer: Malignant hyperthermia susceptibility
Unexplained anesthetic deaths in young family members are a classic red flag for malignant hyperthermia susceptibility, an autosomal dominant condition.
Question 2: Which preoperative NPO guideline applies to clear liquids in a healthy adult before elective general anesthesia per ASA guidelines?
- Nothing by mouth after midnight
- 2 hours before anesthesia (Correct answer)
- 4 hours before anesthesia
- 6 hours before anesthesia
Correct answer: 2 hours before anesthesia
ASA guidelines allow clear liquids up to 2 hours before elective procedures in healthy adults to reduce aspiration risk while minimizing patient discomfort.
Question 3: A patient taking SSRIs reports they stopped their medication abruptly three days ago. Which perioperative risk is MOST associated with this history?
- Serotonin syndrome with opioid administration
- Increased MAC requirement for volatile agents
- Prolonged paralysis from neuromuscular blockers
- Withdrawal-induced seizures (Correct answer)
Correct answer: Withdrawal-induced seizures
Abrupt SSRI discontinuation can cause withdrawal syndrome including seizures, dizziness, and paresthesias, increasing perioperative instability.
Question 4: During a preoperative phone screening, a patient states she was told she has 'a heart murmur' but has never had a cardiac workup. She is now scheduled for a colonoscopy under MAC. What is the BEST next step?
- Proceed; colonoscopy is low-risk and doesn't require cardiac evaluation
- Obtain a cardiology clearance before scheduling (Correct answer)
- Ask the patient to bring her medical records on the day of surgery
- Perform an ECG on the day of the procedure
Correct answer: Obtain a cardiology clearance before scheduling
An uncharacterized heart murmur warrants cardiology evaluation to rule out hemodynamically significant valvular disease before elective sedation.
Question 5: A preoperative nurse reviews that a patient takes varenicline (Chantix) for smoking cessation. Which behavioral consideration should be documented related to this medication?
- Risk of bronchospasm intraoperatively
- Neuropsychiatric symptoms including mood changes and suicidal ideation (Correct answer)
- Prolonged sedation postoperatively
- Increased anesthetic requirements
Correct answer: Neuropsychiatric symptoms including mood changes and suicidal ideation
Varenicline carries an FDA warning for neuropsychiatric adverse effects including depression, agitation, and suicidal ideation that must be documented preoperatively.
Question 6: Which preoperative intervention MOST effectively reduces patient anxiety in the ambulatory surgical setting?
- Routine administration of oral midazolam to all patients
- Structured patient education and clear explanation of the surgical process (Correct answer)
- Restricting family presence during preoperative preparation
- Keeping preoperative waiting time to less than 15 minutes
Correct answer: Structured patient education and clear explanation of the surgical process
Evidence consistently shows that structured patient education and procedural explanations are among the most effective non-pharmacological anxiety reduction strategies.
Question 7: A preoperative assessment reveals that a patient has chronic kidney disease with a GFR of 28 mL/min. Which anesthetic consideration is MOST relevant to document?
- Increased risk of malignant hyperthermia
- Altered drug metabolism and prolonged action of renally cleared medications (Correct answer)
- Higher MAC requirements for volatile agents
- Increased risk of latex allergy
Correct answer: Altered drug metabolism and prolonged action of renally cleared medications
Reduced GFR impairs renal clearance of many drugs including muscle relaxants and opioids, prolonging their effects and requiring dose adjustments.
