Pass the NREMT Medical Technicians EMT Questions and answers with ExamsMirror

Organophosphates are commonly found in pesticides and insecticides, which are often stored in tool sheds. NREMT training emphasizes recognition of cholinergic toxidrome, frequently summarized by the mnemonic SLUDGE (Salivation, Lacrimation, Urination, Defecation, Gastrointestinal distress, Emesis).

Option C is correct because the patient’s symptoms—drooling, tearing, abdominal pain, and runny nose—are hallmark signs of organophosphate poisoning.

Option A (naphthalene) primarily causes hemolysis and neurologic symptoms.

Option B (hydrogen sulfide) causes respiratory distress and altered mental status, not secretions.

Option D causes chemical pneumonitis, not cholinergic symptoms.

NREMT stresses early identification of toxic exposures, scene safety, decontamination awareness, and rapid transport for definitive care.

Given fall with head trauma and absent respirations, the most concerning cause is spinal injury, particularly a cervical spine fracture. A high cervical injury (C1–C4) can paralyze the diaphragm, leading to apnea despite a beating heart.

Brain herniation can also depress respirations but often presents with unequal pupils, posturing, and Cushing’s triad (not described here). Commotio cordis is sudden cardiac arrest from blunt chest trauma (not head). Open pneumothorax affects chest mechanics, not directly linked here.

If a choking patient becomes unresponsive, EMTs should:

Check for a pulse

Begin chest compressions if no pulse is foundChest compressions can help dislodge the object. After compressions, the airway should be opened and inspected. Back blows are not appropriate for unconscious patients.

Ventilation is attempted after clearing the airway or if no object is seen. Do not withhold compressions waiting for object removal.

Pursed-lip breathing is a classic compensatory mechanism seen in patients with emphysema, a form of chronic obstructive pulmonary disease (COPD). According to NREMT education, emphysema is characterized by destruction of the alveolar walls, which leads to loss of lung elasticity. This loss prevents the small airways from remaining open during exhalation.

Option A is correct because pursed-lip breathing creates positive pressure in the airways during exhalation. This pressure helps keep collapsed airways open longer, allowing trapped air to escape and improving ventilation. It also reduces the work of breathing and helps alleviate dyspnea.

Option B is incorrect because decreased hemoglobin affects oxygen-carrying capacity, not airway mechanics or breathing patterns.

Option C is more commonly associated with chronic bronchitis, not emphysema.

Option D is incorrect because diaphragmatic dysfunction is not the primary cause of pursed-lip breathing.

NREMT emphasizes recognizing compensatory breathing patterns in chronic lung disease to guide supportive care, including oxygen administration and positioning.

Albuterol, a common beta-2 adrenergic agonist used in inhalers, stimulates bronchial smooth muscle relaxation. However, stimulation of beta receptors can also produce systemic effects such as:

Tachycardia (due to beta-1 cross-reactivity)

Nervousness (from central stimulation)

Coughing (a local airway response)

Confusion and drowsiness are not typical side effects of beta-agonists. Hypotension is rare unless severe overdose occurs.
