DAANCE - Dental Anesthesia Assistant National Certification Examination Patient Assessment and Preparation Questions and Answers 1 — Questions and Answers
Question 1: A 58-year-old male patient presents for multiple extractions under IV sedation. He has a history of well-controlled type 2 diabetes and hypertension, for which he takes daily medication. He reports being a social drinker and smokes half a pack of cigarettes per day. According to the ASA Physical Status Classification System, how would this patient most likely be classified?
- ASA I
- ASA II (Correct answer)
- ASA III
- ASA IV
Correct answer: ASA II
The patient would be classified as ASA II. An ASA II patient has mild systemic disease that is well-controlled, such as the patient's type 2 diabetes and hypertension. Other factors like social drinking and smoking also place him in this category. ASA I is a normal, healthy patient. ASA III is a patient with severe systemic disease that limits activity, and ASA IV is a patient with severe systemic disease that is a constant threat to life.
Question 2: Which of the following is the primary reason for requiring a patient to be NPO (nothing by mouth) for a specified period before receiving deep sedation or general anesthesia?
- To prevent nausea and vomiting after the procedure.
- To reduce the risk of aspiration of gastric contents. (Correct answer)
- To ensure the anesthetic medications are absorbed properly.
- To decrease the patient's metabolic rate during surgery.
Correct answer: To reduce the risk of aspiration of gastric contents.
The primary reason for pre-operative fasting (NPO) is to reduce the volume of stomach contents, which minimizes the risk of pulmonary aspiration if the patient were to regurgitate while sedated. Anesthetic agents can depress protective airway reflexes, making aspiration a serious and potentially life-threatening complication.
Question 3: During a preoperative airway assessment, the dental anesthesia assistant asks the patient to open their mouth and protrude their tongue. The assistant can only see the soft palate and the base of the uvula. How would this finding be classified according to the Mallampati scoring system?
- Class I
- Class II
- Class III (Correct answer)
- Class IV
Correct answer: Class III
This finding corresponds to a Mallampati Class III. In a Class III airway, the soft palate and only the base of the uvula are visible. A Class I shows the entire soft palate, uvula, and pillars; a Class II shows the soft palate, fauces, and most of the uvula; and a Class IV shows only the hard palate.
Question 4: A thorough review of a patient's medical history is crucial before administering anesthesia. Which of the following is LEAST likely to be a primary focus of this review?
- History of allergies and adverse drug reactions.
- List of current medications, including supplements.
- Patient's dental treatment history. (Correct answer)
- Presence of cardiovascular or respiratory diseases.
Correct answer: Patient's dental treatment history.
While the patient's dental history is important for the treatment plan, it is the least critical component of the *anesthesia-specific* medical history review. The primary focus for patient safety during anesthesia is on identifying systemic conditions (like heart or lung disease), potential drug interactions from current medications, and any history of allergies or adverse reactions to anesthetic agents.
Question 5: A 25-year-old healthy, non-smoking female patient (ASA I) is scheduled for wisdom teeth extraction under sedation at 10:00 AM. According to general NPO guidelines for clear liquids, what is the latest time she should be instructed to have a drink of water?
- 10:00 PM the night before
- 4:00 AM
- 8:00 AM (Correct answer)
- 9:30 AM
Correct answer: 8:00 AM
Standard NPO guidelines often allow the intake of clear fluids up to 2 hours before a procedure. Some guidelines may recommend 4-6 hours. Given the options, 8:00 AM (2 hours prior) is the most appropriate latest time. Solids are typically restricted for 8 hours or more. It's crucial to follow the specific protocol of the office and anesthesiologist.
Question 6: When preparing a patient for a sedation appointment, which of the following is an essential logistical arrangement that must be confirmed beforehand?
- The patient has paid their estimated co-payment.
- The patient has a responsible adult escort for transportation home. (Correct answer)
- The patient has scheduled a follow-up appointment.
- The patient has brought their toothbrush and floss.
Correct answer: The patient has a responsible adult escort for transportation home.
Patient safety dictates that anyone receiving sedation must have a responsible adult to escort them home and stay with them for a period post-operatively. The sedative and anesthetic agents impair judgment, coordination, and reflexes, making it unsafe for the patient to drive or travel alone.
