Experience the Quality With Free EMT Exam Questions That Helps Candidates Pass

Oral glucose is appropriate if the patient can safely swallow and follow commands. Option B is ALS-level. Option C is unnecessary since patient has a pulse. Option D delays critical care. Prompt glucose administration restores mental status and prevents seizure or coma.

A semiconscious patient with an intact gag reflex is likely to retch or vomit with an oropharyngeal airway (OPA). In such cases, a nasopharyngeal airway (NPA) is preferred because it is better tolerated in patients who are not deeply unresponsive. Correct sizing typically uses the distance from the tip of the patient’s nose to the earlobe or angle of the jaw. Lubricate and insert bevel toward the septum unless manufacturer guidelines specify otherwise. Always consider contraindications: suspected basilar skull fracture (e.g., significant midface trauma, CSF rhinorrhea, raccoon eyes, Battle’s sign) or severe nasal injury may preclude NPA use. Option A is inappropriate due to gag reflex. Option C provides no airway protection and risks obstruction. Option D is beyond EMT scope in most systems; EMTs focus on BLS airway management, including positioning, suctioning, OPAs/NPAs, and BVM ventilations. Continuous reassessment for airway patency, protective reflexes, and need for assisted ventilation is essential.

GCS evaluates eye (E), verbal (V), and motor (M) responses. Eye opening to pain is E2 (4-spontaneous, 3-to voice, 2-to pain, 1-none). Incomprehensible sounds are V2 (5-oriented, 4-confused, 3-inappropriate words, 2-incomprehensible sounds, 1-none). Withdrawal from pain is M4 (6-follows commands, 5-localizes pain, 4-withdraws, 3-abnormal flexion/decorticate, 2-extension/decerebrate, 1-none). Summing E2 + V2 + M4 = 8. A GCS of 8 indicates severe impairment and risk for airway compromise (“GCS 8, intubate” is an ALS consideration; for EMTs, it underscores aggressive airway management and rapid transport). Frequent reassessment is important, as GCS can change with hypoxia, hypoglycemia, or intracranial injury. Combine GCS with the primary assessment (airway, breathing, circulation), pupil exam, and vital signs. Maintain airway patency, provide oxygen/ventilations as needed, control external bleeding, and prioritize rapid transport to a facility capable of managing potential traumatic brain injury.

Tourniquets are the definitive treatment when direct pressure fails for severe extremity bleeding. Option A and C are outdated and ineffective alone. Option D stabilizes fracture but does not control uncontrolled bleeding first. Rapid hemorrhage control is essential to prevent exsanguination and death.

An unresponsive hypoglycemic patient cannot safely swallow oral glucose. EMTs must first manage airway and ventilations with BVM to prevent hypoxia. Option C is ALS-level care. Option D delays intervention. Oral glucose is appropriate only when the patient is conscious and able to swallow. Airway and breathing always take precedence in unresponsive patients.
