1. What percentage of total body surface area has been burned in a 5-year-old child who experienced partial-thickness burns to his head, anterior chest, and both upper extremities?
- A. 45%
- B. 63%
- C. 72%
- D. 54%
Correct answer: A
Rationale: According to the pediatric rule of nines, the head and neck represent 18%, the anterior chest and abdomen 18%, and each arm 9%. By adding these percentages (18% + 18% + 9% + 9% = 45%), we find that 45% of the total body surface area has been burned in this child.
2. In which of the following situations would the EMT MOST likely deliver a baby at the scene?
- A. A tornado has struck and blocked the only route to the hospital.
- B. Contractions are 8 to 10 minutes apart and irregular.
- C. The amniotic sac has ruptured, and contractions occur regularly.
- D. The hospital is 15 miles away, and crowning is not present.
Correct answer: A
Rationale: The EMT may be required to deliver a baby at the scene when external factors like a tornado have blocked the only route to the hospital, making it impossible to reach the medical facility in time for delivery. In such emergencies, the EMT must be prepared to manage the childbirth process until further medical assistance can be obtained.
3. When assisting ventilations in a 4-year-old child with a bag-valve mask, what should the EMT do?
- A. Deliver each breath over 2 to 3 seconds.
- B. Ensure the appropriate mask size is used.
- C. Block the pop-off valve if needed to achieve adequate chest rise.
- D. Reassess the pulse rate after 60 seconds.
Correct answer: C
Rationale: When assisting ventilations in a 4-year-old child with a bag-valve mask, the EMT should block the pop-off valve if needed to achieve adequate chest rise. This action helps ensure effective ventilation and adequate oxygenation in the child. Blocking the pop-off valve allows for better control over the volume of air delivered and can help maintain positive pressure in the airway, assisting in improving oxygenation and ventilation in the child. Choices A, B, and D are incorrect because delivering each breath over 2 to 3 seconds is a general guideline but may need adjustment based on patient response, ensuring the appropriate mask size is important but not the primary concern in this scenario, and reassessing the pulse rate is not directly related to the ventilation technique being discussed.
4. Atta, who weighs 20kg, has been prescribed amoxicillin 500 mg b.i.d. The drug information indicates a daily dose of amoxicillin at 50 mg/kg/day in two divided doses. What is the safest dose in milligrams for this child?
- A. 1000 mg
- B. 750 mg
- C. 500 mg
- D. 250 mg
Correct answer: A
Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.
5. Alice is rushed to the emergency department during an acute, severe prolonged asthma attack and is unresponsive to usual treatment. The condition is referred to as which of the following?
- A. Status asthmaticus
- B. Reactive airway disease
- C. Intrinsic asthma
- D. Extrinsic asthma
Correct answer: A
Rationale: Status asthmaticus is a life-threatening condition characterized by a severe and prolonged asthma attack that does not respond to standard treatments. It requires immediate medical intervention to prevent respiratory failure and potential fatality. Reactive airway disease, intrinsic asthma, and extrinsic asthma do not specifically denote the severity and unresponsiveness to treatment seen in status asthmaticus.
