AEMCA - Advanced Emergency Medical Care Assistant Pediatric Emergencies Questions and Answers — Questions and Answers
Question 1: You are assessing a 2-year-old child from across the room using the Pediatric Assessment Triangle (PAT). You note the child is crying, has audible stridor, and visible intercostal retractions. Their skin appears pink. Based on the PAT, which category best describes the child's physiological state?
- Cardiopulmonary failure
- Respiratory distress (Correct answer)
- Decompensated shock
- Central nervous system dysfunction
Correct answer: Respiratory distress
The Pediatric Assessment Triangle (PAT) evaluates Appearance, Work of Breathing, and Circulation to the skin. In this scenario, the child's Appearance is acceptable (crying is an appropriate response). The Circulation is also normal (pink skin). However, there are clear signs of increased Work of Breathing (stridor, retractions). An abnormality in only the Work of Breathing component of the PAT indicates respiratory distress.
Question 2: A 3-year-old presents with a sudden onset of high fever, severe sore throat, drooling, and a muffled voice. The child is sitting upright in a 'tripod' position and appears anxious. Which of the following conditions is most likely, and what is a critical prehospital consideration?
- Croup; administer nebulized epinephrine immediately.
- Anaphylaxis; prepare for immediate intubation.
- Epiglottitis; avoid any action that could agitate the child. (Correct answer)
- Bacterial tracheitis; perform deep suctioning to clear secretions.
Correct answer: Epiglottitis; avoid any action that could agitate the child.
The classic presentation of a sudden high fever, drooling, dysphagia (difficulty swallowing), distress, and a muffled 'hot potato' voice strongly suggests epiglottitis, a true medical emergency. A critical prehospital consideration is to keep the child calm and avoid any procedures, such as looking in the throat with a tongue blade, that could cause agitation and lead to a complete laryngospasm and airway obstruction.
Question 3: You are managing a 5-year-old, 18 kg patient in ventricular fibrillation. According to PALS guidelines, what is the appropriate initial energy dose for defibrillation?
- 18 Joules
- 36 Joules (Correct answer)
- 72 Joules
- 100 Joules
Correct answer: 36 Joules
The current Pediatric Advanced Life Support (PALS) guidelines recommend an initial energy dose for defibrillation of 2 to 4 Joules per kilogram (J/kg). For an 18 kg child, the initial shock should be calculated at 2 J/kg, which equals 36 Joules (18 kg * 2 J/kg). Subsequent shocks can be increased, typically to 4 J/kg or higher.
Question 4: An 18-month-old child involved in a traumatic incident is showing signs of compensated shock, including tachycardia, cool extremities, and a capillary refill time of 4 seconds. According to pediatric resuscitation guidelines, what is the correct initial fluid bolus?
- 5 mL/kg of a colloid solution over 30 minutes.
- 10 mL/kg of D5W as rapidly as possible.
- 20 mL/kg of an isotonic crystalloid over 5-20 minutes. (Correct answer)
- 40 mL/kg of 0.45% saline over one hour.
Correct answer: 20 mL/kg of an isotonic crystalloid over 5-20 minutes.
For pediatric patients in shock (hypovolemic or septic, without cardiogenic cause), the standard initial intervention is a rapid fluid bolus of 20 mL/kg of an isotonic crystalloid solution, such as Normal Saline or Ringer's Lactate. This bolus should be administered quickly, typically over 5 to 20 minutes, followed by reassessment of the patient's perfusion status.
Question 5: You are called for a 2-year-old who had a generalized tonic-clonic seizure. Upon arrival, the seizure has stopped, and the child is postictal but rousable. The parents state the seizure lasted about 3 minutes and the child has a fever of 39.5°C. What is the most appropriate next action?
- Administer a prophylactic dose of midazolam to prevent another seizure.
- Establish IV access and administer an antipyretic immediately.
- Perform a blood glucose check and provide supportive care, including cooling measures.
- Immediately transport without further assessment to rule out meningitis. (Correct answer)
Correct answer: Immediately transport without further assessment to rule out meningitis.
This presentation is consistent with a simple febrile seizure, which is typically benign and self-limiting. The priority after the seizure has ceased is supportive care. This includes assessing the patient (including a blood glucose check, as hypoglycemia can cause seizures), ensuring a patent airway, and initiating passive cooling measures for the fever. Prophylactic benzodiazepines are not indicated for a seizure that has already terminated.
Question 6: Which of the following is a key anatomical difference in the pediatric airway compared to an adult's that is critical to consider during airway management?
- The epiglottis is smaller and stiffer, making it easier to lift with a curved blade.
- The narrowest portion of the airway is the glottic opening, similar to adults.
- The tongue is proportionally smaller, creating more space in the oropharynx.
- The larynx is positioned more anteriorly and superiorly (higher in the neck). (Correct answer)
Correct answer: The larynx is positioned more anteriorly and superiorly (higher in the neck).
In infants and young children, the larynx is located higher in the neck (around C3-C4) and is positioned more anteriorly compared to an adult's (C4-C5). This anatomical difference often requires adjustments in technique during laryngoscopy, such as applying external laryngeal manipulation or using a straight blade. The pediatric tongue is proportionally larger, and the narrowest part of the airway is the cricoid cartilage, not the glottic opening.
