Special Populations: Pediatric, Geriatric, and Obstetric Patients - NREMT EMT Level

1. What is the most common mechanism of serious injury in older adults seen by EMS?

   Falls. Mobility issues, osteoporosis, and comorbidities make falls a leading cause of fractures and head injuries in geriatrics.

2. Which geriatric physiologic change increases risk of hypothermia during illness or trauma?

   Decreased thermoregulation and subcutaneous fat. Aging reduces these protective mechanisms, making elderly patients more vulnerable to environmental temperature changes.

3. What is the preferred initial oxygen strategy for a stable child with mild respiratory distress?

   Titrate oxygen to maintain adequate SpO2 per protocol. Titration prevents oxygen toxicity while ensuring saturation levels support oxygenation without excess.

4. What anatomical feature makes infants and children more prone to airway obstruction?

   Smaller airway diameter and proportionally larger tongue. These features narrow the airway passage, increasing susceptibility to blockage from swelling or foreign objects.

5. Identify the correct immediate action when a prolapsed umbilical cord is visible at the vagina.

   Elevate presenting part, knee-chest/Trendelenburg, rapid transport. These actions relieve cord compression, maintain fetal oxygenation, and facilitate emergent delivery.

6. What patient position best reduces supine hypotensive syndrome in late pregnancy?

   Left lateral recumbent or manual left uterine displacement. This relieves aortocaval compression by the gravid uterus, improving venous return and maternal cardiac output.

7. Which obstetric complication is suggested by painful third-trimester bleeding with a rigid uterus?

   Placental abruption. Abruption involves premature placental separation, leading to pain from uterine irritation and potential fetal distress.

8. Which pediatric shock type is most common, and what is the typical blood pressure finding early?

   Hypovolemic; blood pressure often normal until late. Children often experience hypovolemic shock from trauma or dehydration, with compensatory mechanisms maintaining BP until severe loss.

9. Which pediatric assessment tool uses appearance, work of breathing, and circulation to skin?

   Pediatric Assessment Triangle (PAT). PAT provides a rapid visual assessment to identify life-threatening conditions in children without initial physical contact.

10. Which obstetric complication is suggested by painless third-trimester vaginal bleeding?

    Placenta previa. Previas involve low placental implantation covering the cervix, causing bleeding without contractions as the cervix dilates.

11. What is the correct pediatric ventilation rate with a bag-mask for an infant with a pulse?

    1 breath every 3–5 seconds. This rate supports oxygenation needs while avoiding over-ventilation in infants with a palpable pulse.

12. What is the most appropriate initial action when an older patient has new confusion?

    Check for hypoxia and hypoglycemia early. These reversible causes are common in elderly altered mental status and should be ruled out promptly to guide treatment.

13. What is the earliest and most consistent indicator of respiratory distress in children?

    Tachypnea. Increased respiratory rate compensates for hypoxia or acidosis before other signs like retractions appear.

14. Identify the correct pediatric ventilation rate with a bag-mask for a child with a pulse.

    1 breath every 3–5 seconds. This rate ensures adequate oxygenation without causing hyperventilation in pediatric patients with spontaneous circulation.

15. What is the most appropriate method to estimate a child's weight for dosing when unknown?

    Length-based tape (Broselow or equivalent). This tool correlates length to estimated weight and equipment sizes, improving accuracy in emergencies.

16. Which pediatric medication dosing method is generally used for most drugs in EMS?

    Weight-based dosing in mg/kg. Dosing by weight accounts for variations in body size and metabolism, ensuring safe and effective medication administration.

17. Which positioning is most appropriate to open an infant airway when no trauma is suspected?

    Neutral sniffing position. This position aligns the oral, pharyngeal, and tracheal axes optimally for infants' proportionally larger occiputs.

18. Which geriatric assessment pitfall can mask serious illness despite normal vital signs?

    Blunted tachycardia and fever response. Aging blunts physiologic responses, leading to atypical presentations where vital signs do not reflect infection or shock severity.

19. Which medication class commonly increases bleeding risk and alters trauma assessment in geriatrics?

    Anticoagulants and antiplatelets. These drugs impair clotting, potentially worsening internal bleeding and complicating injury evaluation in older adults.

20. Which pain-assessment scale is most appropriate for a nonverbal infant or toddler?

    FLACC scale. FLACC evaluates pain through observable behaviors like face, legs, activity, cry, and consolability in preverbal children.

21. What is the preferred initial assessment approach for an infant or small child to reduce anxiety?

    Assess from toe-to-head while the child stays with caregiver. This reverse approach minimizes fear by starting with less invasive areas and keeping the child in a comforting environment.

22. Which pediatric finding indicates impending respiratory failure rather than simple distress?

    Decreased mental status or bradycardia with poor effort. These signs reflect decompensation, indicating exhaustion of compensatory mechanisms and need for immediate intervention.

23. Which sign is most reliable for detecting hypoperfusion in infants and young children?

    Tachycardia. Children compensate for volume loss by increasing heart rate before blood pressure drops significantly.
