Free RDA Recognition and Management of Medical Emergencies Questions and Answers 1 — Questions and Answers
Question 1: A patient in the dental chair suddenly becomes pale, sweaty, and reports feeling faint. What is the immediate and most appropriate action?
- Administer aromatic spirits of ammonia
- Place the patient in a supine position with feet slightly elevated (Correct answer)
- Offer the patient a sugary drink
- Sit the patient upright and provide a paper bag
Correct answer: Place the patient in a supine position with feet slightly elevated
Syncope, or fainting, is the most common medical emergency in a dental office. Placing the patient in a supine or Trendelenburg position (feet slightly elevated) helps to increase blood flow to the brain, which is the primary goal of initial management.
Question 2: An anxious patient begins to breathe rapidly and complains of tingling in their fingers and lightheadedness. This is most likely a sign of:
- Anaphylactic shock
- Hypoglycemia
- Hyperventilation (Correct answer)
- Angina pectoris
Correct answer: Hyperventilation
These are classic signs and symptoms of hyperventilation, which is caused by breathing too rapidly and exhaling too much carbon dioxide. Management involves calming the patient and helping them slow their breathing rate.
Question 3: During a procedure, a patient with a known history of diabetes becomes confused, irritable, and their skin is cold and clammy. What should be administered immediately?
- A glass of water
- An oxygen mask
- Nitroglycerin
- A source of concentrated sugar, like glucose gel (Correct answer)
Correct answer: A source of concentrated sugar, like glucose gel
These symptoms are indicative of hypoglycemia, or low blood sugar. The immediate treatment is to provide a readily available source of sugar, such as glucose gel, orange juice, or non-diet soda, to quickly raise their blood glucose levels.
Question 4: A patient develops a severe allergic reaction with difficulty breathing, hives, and a rapid drop in blood pressure. This condition is known as anaphylaxis. What is the primary drug used to manage this emergency?
- Diphenhydramine (Benadryl)
- Epinephrine (Correct answer)
- Albuterol
- Aspirin
Correct answer: Epinephrine
Anaphylaxis is a life-threatening allergic reaction. Epinephrine is the drug of choice because it is a potent bronchodilator and vasoconstrictor, which helps to open the airways and increase blood pressure.
Question 5: If a patient experiences a grand mal seizure in the dental chair, the primary responsibility of the dental team is to:
- Insert a padded tongue blade into the patient's mouth
- Firmly restrain the patient's arms and legs
- Prevent the patient from injury and clear the area (Correct answer)
- Immediately administer oxygen
Correct answer: Prevent the patient from injury and clear the area
During a convulsive seizure, the main priority is to prevent the patient from injuring themselves. This involves clearing the area of any sharp or hard objects and gently protecting their head, without actively restraining their movements.
Question 6: A patient with a history of angina pectoris complains of crushing chest pain. After the dentist administers one dose of nitroglycerin, the pain is not relieved. What is the next appropriate step?
- Administer a second dose of nitroglycerin after 5 minutes (Correct answer)
- Immediately begin CPR
- Administer aspirin and wait 15 minutes
- Assume it is a heart attack and only administer oxygen
Correct answer: Administer a second dose of nitroglycerin after 5 minutes
Standard protocol for angina is to administer up to three doses of nitroglycerin, five minutes apart. If the pain persists after the first dose, a second dose should be given while preparing to activate emergency medical services (EMS), as the condition could be a more serious myocardial infarction (heart attack).
