NREMT Special Populations & Pediatric Care 2 — Questions and Answers

Question 1: When assessing an elderly patient who has fallen, which of the following should the EMT consider in addition to the injury sustained?

The patient's family dynamics and home environment
Underlying causes of the fall such as syncope, arrhythmia, or TIA that may represent a serious medical problem (Correct answer)
Whether the patient has home insurance
The patient's dietary history from the past week

Correct answer: Underlying causes of the fall such as syncope, arrhythmia, or TIA that may represent a serious medical problem

Falls in the elderly are often symptomatic of an underlying medical cause (syncope from cardiac arrhythmia, hypotension, TIA, etc.). Treating only the injury without investigating the cause misses potentially life-threatening conditions.

Falls are one of the most common chief complaints in elderly patients. While traumatic injuries from falls (hip fractures, head trauma, spinal injuries) must be identified and treated, the EMT must also investigate what caused the fall. In many elderly patients, the fall is a presenting symptom of an underlying medical problem. Common medical causes of falls in the elderly: syncope from cardiac arrhythmias (bradyarrhythmias, tachyarrhythmias, heart block), orthostatic hypotension (blood pressure drop on standing, often medication-induced), vasovagal syncope, transient ischemic attack or stroke, hypoglycemia, medication side effects (sedatives, antihypertensives, diuretics), and vestibular dysfunction. A cardiac monitor and blood glucose should be early priorities in elderly fall patients. The elderly are also at increased risk for significant injury from seemingly minor falls due to osteoporosis, anticoagulant use (warfarin, aspirin, NOACs), cerebral atrophy (increased subdural hematoma risk), and reduced physiological reserve. Signs of significant injury may be blunted — an elderly patient can have a hip fracture without the classic presentation, and intracranial hemorrhage may develop slowly. A thorough assessment and low threshold for transport are essential.

Question 2: A bariatric (obese) patient requires CPR. Which consideration is most important for effective chest compressions?

Using a pediatric AED because adult pads may not fit
Ensuring compression depth is sufficient despite the increased chest wall thickness, and considering two-hand stacking technique (Correct answer)
Reducing compression rate to 60/min for obese patients
Placing the patient in the prone position for better compression effectiveness

Correct answer: Ensuring compression depth is sufficient despite the increased chest wall thickness, and considering two-hand stacking technique

Obese patients may require more force to achieve the required 2-2.4 inch compression depth due to increased chest wall thickness. Two-hand stacking or using body weight may be necessary. Compression rate is 100-120/min for all adults.

Providing effective CPR to a bariatric patient presents several challenges. The primary concern is achieving adequate compression depth (2 to 2.4 inches for adults per AHA guidelines) in a patient with increased chest wall thickness. Standard single-arm compression technique may not generate sufficient force, and the EMT may need to: use a two-handed stacking technique (one hand on top of the other with locked elbows), lean in more steeply over the patient to use body weight, or have larger responders perform compressions. Rescuer fatigue is also accelerated when performing compressions on a bariatric patient — more frequent rotation of compressors (every 1-2 minutes rather than 2 minutes) helps maintain compression quality. Transporting a bariatric patient to a weight-rated stretcher and vehicle that can accommodate them is also an important logistical consideration. AED pads are sized for adults regardless of body habitus — standard adult pads are appropriate for bariatric patients. Positioning for CPR should be supine on a firm surface; prone positioning does not allow adequate chest compression. The compression rate (100-120/min) and ratio (30:2) are the same for all adults.

Question 3: An EMT encounters a patient who is deaf and cannot communicate verbally. The best approach to communication is:

Speak louder and more slowly directly into the patient's ear
Use a communication board, writing, gestures, or request an ASL interpreter via phone/video (Correct answer)
Skip the history and rely entirely on physical examination
Contact medical direction to cancel the call

Correct answer: Use a communication board, writing, gestures, or request an ASL interpreter via phone/video

Alternative communication strategies — writing, communication boards, gestures, or remote ASL interpretation via video — allow effective assessment of deaf patients. Shouting into the ear is ineffective for patients who are deaf.

Effective communication with deaf or hearing-impaired patients requires alternative strategies. Pen and paper or a phone screen for typing is the most immediately accessible tool available to any EMT. Communication boards with common phrases and body diagrams allow patients to point to locations of pain or describe symptoms. Many deaf patients can lip-read — speaking slowly and facing the patient while enunciating clearly (not shouting) is helpful. Gestures and pointing to body parts can supplement other communication methods. For more complex communication needs, video remote interpreter (VRI) services can connect a patient with a certified American Sign Language (ASL) interpreter via smartphone or tablet. Many hospitals and EMS systems have access to these services. Having a family member who signs present can also facilitate communication, though using family members as medical interpreters has limitations (accuracy, confidentiality, emotional involvement). Shouting into the ear of a deaf patient is ineffective — the patient cannot hear regardless of volume. It may also cause discomfort and damage to any residual hearing. EMTs should approach deaf and hearing-impaired patients with patience, flexibility, and creativity. Documenting communication barriers and the methods used in the PCR helps the receiving facility prepare for continued communication needs.

Question 4: When caring for a patient with an intellectual disability, the EMT should:

Assume the patient cannot understand anything and speak only to caregivers
Speak directly to the patient using clear, simple language at an appropriate level, involve caregivers as supplemental resources (Correct answer)
Skip the assessment since history cannot be obtained
Sedate the patient for easier management

Correct answer: Speak directly to the patient using clear, simple language at an appropriate level, involve caregivers as supplemental resources

Patients with intellectual disabilities have varying levels of understanding. The EMT should speak directly to the patient in simple, clear language, observe their responses, and use caregivers to supplement the history. Never assume no comprehension.

Patients with intellectual disabilities range enormously in their functional abilities and communication levels — from individuals who are nearly indistinguishable from the general population to those with profound limitations in communication and cognition. The EMT should never assume a patient's level of understanding based on appearance or a diagnosis label. Best practices for communicating with patients with intellectual disabilities: introduce yourself and explain what you are doing before doing it (reduces anxiety and unexpected touch); use short, simple sentences and clear language (avoid medical jargon); speak in a calm, unhurried tone; use visual aids or gestures when helpful; allow extra time for the patient to respond; observe behavioral cues (grimacing, withdrawing from touch, pointing to areas of discomfort) that supplement verbal communication; and involve trusted caregivers or support persons as additional sources of history and as comfort figures. Caregivers often have important medical information: the patient's baseline behavior, existing conditions, medications, known allergies, communication strategies that work for this specific patient, and whether behavioral changes represent acute illness. This information should supplement but not replace direct interaction with the patient. Legal issues — such as guardianship and consent — may apply and should be addressed per agency protocol.

Question 5: Compared to younger adults, elderly patients are more susceptible to hypothermia because:

They eat more calories and generate excessive heat
They have decreased thermoregulatory ability, less subcutaneous fat, reduced metabolic rate, and often take medications that impair heat conservation (Correct answer)
They are more likely to be outdoors in cold weather
They have increased body surface area relative to volume

Correct answer: They have decreased thermoregulatory ability, less subcutaneous fat, reduced metabolic rate, and often take medications that impair heat conservation

Aging reduces thermoregulatory effectiveness through multiple mechanisms: decreased muscle mass (less heat generation), thinning subcutaneous fat (less insulation), impaired vasoconstriction response, reduced metabolic rate, and medications that affect temperature regulation.

Thermoregulation — the body's ability to maintain core temperature within a narrow range — becomes significantly impaired with aging through multiple converging mechanisms. These include: decreased muscle mass reduces the capacity for shivering thermogenesis; thinning and redistribution of subcutaneous fat reduces insulation; blunted vasoconstrictive response to cold impairs peripheral heat conservation; reduced basal metabolic rate decreases baseline heat production; impaired sensation may reduce awareness of cold temperatures; and comorbid conditions (hypothyroidism, malnutrition, Parkinson's disease) further impair thermoregulation. Medications commonly taken by the elderly can worsen cold susceptibility: beta-blockers reduce heart rate and metabolic response to cold; sedatives and antipsychotics blunt the shivering response; vasodilators prevent compensatory vasoconstriction; and diuretics can cause dehydration affecting thermoregulation. The practical implication is that an elderly patient can develop hypothermia at temperatures that would not affect a healthy young adult — including indoor temperatures that are merely 'cool' (65-70°F) in a poorly heated apartment. EMTs should always measure rectal or core temperature in elderly patients with altered mental status, as hypothermia may not be clinically obvious. Treatment includes gentle rewarming (avoid rough handling which can cause ventricular fibrillation), removal from the cold environment, and warm blankets.

Question 6: When assessing a patient who is autistic and displays agitation during the assessment, the EMT should:

Use physical restraints immediately to prevent injury
Reduce environmental stimuli, speak calmly, allow extra time, and involve familiar caregivers (Correct answer)
Proceed as quickly as possible to minimize the contact time
Administer sedative medications per protocol immediately

Correct answer: Reduce environmental stimuli, speak calmly, allow extra time, and involve familiar caregivers

Patients with autism may become overwhelmed by sensory stimuli, physical touch, or sudden changes. Reducing stimuli, speaking calmly, taking extra time, and involving trusted persons significantly reduces agitation and facilitates assessment.

Autism spectrum disorder (ASD) includes a wide range of presentations, but sensory processing differences are a common feature. Many individuals with ASD experience hypersensitivity to sounds, lights, touch, and other sensory inputs — the EMS environment (flashing lights, multiple responders, loud voices, unfamiliar touch) can be extremely overwhelming and trigger agitation, behaviors that appear combative, or complete shutdown. Strategies that facilitate assessment and care: dim non-essential lights and silence non-critical alarms; reduce the number of people around the patient; speak in a calm, low-pitched tone; give the patient advance notice before any physical contact ('I am going to put this on your arm now'); allow the patient to maintain some control over the interaction; use familiar caregivers as intermediaries and sources of communication strategies; respect sensory sensitivities regarding touch and personal space; allow extra time for each interaction. Physical restraint should be an absolute last resort, only when safety is immediately at risk and all other strategies have failed. Restraint can dramatically escalate an autistic patient's distress and may cause physical injury. Many EMS systems offer autism-specific training programs (such as AASPIRE) to improve responder capability. Documenting the strategies used and their effectiveness helps the receiving facility continue appropriate care.
