Pediatric, Geriatric, and Obstetric Patients - NREMT EMT Level

What is the proper EMT positioning for a pregnant patient in late pregnancy who is hypotensive or dizzy supine?

Left lateral recumbent or manual uterine displacement to the left. It relieves inferior vena cava compression by the gravid uterus, improving venous return.
Which option best explains why geriatric patients may not show tachycardia during shock?

Blunted physiologic response and beta-blocker use. Aging dulls sympathetic responses, and medications like beta-blockers limit heart rate increase.
What is the most common cause of cardiac arrest in pediatric patients?

Respiratory failure leading to hypoxia. Pediatric arrests often stem from airway issues progressing to oxygen deprivation.
Which option is correct for relieving a severe foreign-body airway obstruction in a conscious infant?

Cycles of $5$ back slaps and $5$ chest thrusts. This technique dislodges obstructions safely in infants without risking abdominal injury.
Which option is correct for relieving a severe foreign-body airway obstruction in a conscious child?

Abdominal thrusts (Heimlich maneuver). It generates intra-abdominal pressure to expel foreign bodies from the airway in children.
Which condition should you suspect when an older adult has confusion after a minor fall and takes anticoagulants?

Intracranial hemorrhage. Anticoagulants heighten bleeding risk from even minor trauma in fragile elderly brains.
What is the preferred method to open the airway in an infant with no trauma suspected?

Neutral position with head tilt–chin lift. Infants have a large occiput, so neutral positioning with slight tilt opens the airway without hyperextension.
What is the correct EMT action for a newborn with meconium-stained fluid who is breathing/crying with good tone?

Routine care and drying; do not suction routinely. Vigorous newborns clear fluids naturally; routine suction risks bradycardia or injury.
What is the compression-to-ventilation ratio for single-rescuer CPR for an infant or child?

$30:2$ . The ratio balances circulation and oxygenation needs for a lone rescuer managing pediatric arrest.
Which airway maneuver should you use to open the airway when pediatric trauma is suspected?

Jaw-thrust maneuver with manual stabilization. It maintains cervical spine alignment while opening the airway in potential trauma cases.
What is the single most important initial step when communicating with a geriatric patient with hearing impairment?

Face the patient and speak clearly at a normal volume. This facilitates lip-reading and clear communication without distorting sound by shouting.
What is the compression-to-ventilation ratio for two-rescuer CPR for an infant or child?

$15:2$ . It optimizes coordination between rescuers, emphasizing more frequent ventilations for pediatric physiology.
Which pulse check site is preferred for an infant during assessment or CPR?

Brachial pulse. The brachial site is easily accessible and reliable for detecting central perfusion in infants.
Which pediatric vital sign trend is the earliest common indicator of shock: hypotension or tachycardia?

Tachycardia. It compensates for hypovolemia early, while blood pressure remains stable until late shock.
What is the most appropriate initial approach when assessing an infant or child to reduce fear and gain cooperation?

Use a calm approach; allow caregiver presence; assess in caregiver's arms. This method minimizes anxiety by maintaining familiarity and security, facilitating a more accurate assessment.
Which pediatric assessment finding is most concerning for impending respiratory failure: fast rate or slow/irregular rate?

Slow or irregular respiratory rate. It indicates decompensation, as children initially compensate with tachypnea before failure.
Which pulse check site is preferred for a child during assessment or CPR?

Carotid or femoral pulse. These sites provide accurate assessment of central circulation in children during emergencies.
What is the correct compression depth for child CPR on a firm surface?

At least $\frac{1}{3}$ the chest depth (about $2$ in or $5$ cm). This depth provides effective cardiac output while accommodating the child's larger chest size.
What is the most common and most serious mechanism of injury for geriatric patients?

Falls. Geriatric mobility issues, osteoporosis, and medications increase fall risk and severity.
What is the best EMT action when a geriatric patient has multiple medications and you suspect an adverse interaction?

Bring all medication containers (or a list) to the receiving facility. Providing medications aids hospital staff in identifying interactions or overdoses accurately.
What is the correct compression depth for infant CPR (single rescuer) on a firm surface?

At least $\frac{1}{3}$ the chest depth (about $1.5$ in or $4$ cm). This depth ensures adequate circulation during CPR without causing injury to the infant's fragile chest.
What is the primary physiologic reason children can deteriorate rapidly during illness or injury?

Limited respiratory reserve; they compensate then decompensate suddenly. Children's smaller airways and higher metabolic demands lead to quick exhaustion of reserves.
Which age-related change increases the risk of hypothermia in geriatric patients?

Reduced thermoregulation and decreased subcutaneous fat. Aging impairs temperature control and insulation, heightening vulnerability to cold environments.
Which intervention is most important to prevent heat loss in an infant or small child after exposure or trauma?

Dry, warm, cover, and minimize exposure to the environment. Infants lose heat rapidly due to high surface area-to-volume ratio and immature thermoregulation.
Which finding indicates imminent delivery: crowning or contractions every $10$ minutes?

Crowning. It shows the fetal head at the vaginal opening, signaling the second stage of labor.
