D) Severe neurological damage Answer: C Explanation: A GCS score of 15 indicates the patient is fully alert with normal neurological function. Question 7. Which airway adjunct is contraindicated in a patient with a suspected cervical spine injury? A) Nasopharyngeal airway B) Oropharyngeal airway C) Endotracheal tube D) Jaw-thrust maneuver Answer: B Explanation: An oropharyngeal airway can cause head movement; the jaw-thrust maneuver is preferred to avoid cervical spine movement in suspected neck injuries. Question 8. What is the primary purpose of a non-rebreather mask? A) Provide low-flow oxygen for minor hypoxia B) Deliver high-concentration oxygen in respiratory distress C) Administer medications
D) Deliver continuous positive airway pressure (CPAP) Answer: B Explanation: The non-rebreather mask delivers high concentrations of oxygen, suitable for patients in respiratory distress or failure. Question 9. Which of the following best describes ventricular fibrillation? A) Slow, regular heart rhythm B) Disorganized electrical activity leading to ineffective heart contractions C) A type of sinus tachycardia D) Complete heart block Answer: B Explanation: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic electrical activity, preventing effective blood circulation. Question 10. In the management of a stroke patient, what does the acronym FAST stand for? A) Face, Arms, Speech, Time
A) Administer naloxone (Narcan) B) Perform CPR immediately C) Provide high-flow oxygen and monitor airway D) Transport to hospital without intervention Answer: C Explanation: Ensuring airway patency and providing oxygen are initial critical steps, with naloxone administered if opioid overdose is confirmed or suspected. Question 13. Which trauma mechanism is most associated with a cervical spine injury? A) Fall from a height onto the feet B) Rapid hyperextension or hyperflexion of the neck C) Blunt trauma to the abdomen D) Low-impact superficial lacerations Answer: B Explanation: Rapid hyperextension or hyperflexion can cause cervical spine injuries, especially in high-energy trauma.
Question 14. What is the most appropriate immobilization technique for a suspected spinal injury? A) Rigid cervical collar and backboard immobilization B) Padding around the neck without immobilization C) Log roll without spinal stabilization D) No immobilization if the patient can walk Answer: A Explanation: Suspected spinal injuries require immobilization with a cervical collar and backboard to prevent further injury. Question 15. Which of the following conditions is characterized by symptoms such as hypertension, proteinuria, and edema during pregnancy? A) Preeclampsia B) Placenta previa C) Ectopic pregnancy D) Uterine rupture Answer: A
Explanation: Epiglottitis causes swelling of the epiglottis, leading to airway obstruction, and requires prompt airway management. Question 18. What is a common sign of impending respiratory failure in a pediatric patient? A) Restlessness and increased respiratory effort B) Calm and shallow breathing C) Pink skin tone D) Excessive salivation only Answer: A Explanation: Increased respiratory effort and agitation often precede respiratory failure in children. Question 19. Which medication is crucial for managing opioid overdose in the pre-hospital setting? A) Epinephrine B) Naloxone (Narcan) C) Nitroglycerin D) Aspirin Answer: B
Explanation: Naloxone is an opioid antagonist used to reverse opioid- induced respiratory depression. Question 20. In geriatric patients, which physiological change most affects drug pharmacokinetics? A) Increased renal clearance B) Decreased liver metabolism C) Increased cardiac output D) Enhanced gastric absorption Answer: B Explanation: Reduced liver function in the elderly decreases drug metabolism, affecting pharmacokinetics. Question 21. Which symptom is most indicative of a myocardial infarction? A) Sudden chest pain radiating to the jaw or arm B) Sudden high fever C) Severe abdominal pain D) Rapid, shallow breathing with coughing Answer: A
Explanation: Cricothyrotomy is an emergency surgical airway performed when other methods fail or are contraindicated. Question 24. Which respiratory condition is characterized by airway narrowing due to inflammation and mucus, often triggered by allergens? A) Asthma B) Pulmonary embolism C) Pneumothorax D) COPD Answer: A Explanation: Asthma involves bronchial constriction from inflammation and mucus, leading to wheezing and dyspnea. Question 25. Which vital sign change is most suggestive of shock? A) Elevated blood pressure B) Tachycardia and hypotension C) Bradycardia with hypertension D) Increased oxygen saturation Answer: B
Explanation: Shock typically presents with tachycardia and hypotension due to inadequate perfusion. Question 26. Which type of shock results from severe blood or fluid loss? A) Cardiogenic shock B) Neurogenic shock C) Hypovolemic shock D) Septic shock Answer: C Explanation: Hypovolemic shock occurs due to significant volume loss from bleeding or dehydration. Question 27. What is the most appropriate initial intervention for a patient with a tension pneumothorax? A) Needle decompression at the second intercostal space, midclavicular line B) Immediate chest tube placement C) Administration of high-flow oxygen only D) Observation and reassessment
Answer: B Explanation: Hypoglycemia requires prompt administration of glucose to restore normal blood sugar levels. Question 30. What is the hallmark sign of anaphylaxis? A) Gradual onset of rash B) Sudden airway edema, hypotension, and skin manifestations C) Isolated abdominal pain D) Fever and chills Answer: B Explanation: Anaphylaxis presents with rapid airway swelling, hypotension, and skin reactions like hives. Question 31. Which type of trauma is most likely to cause a hemothorax? A) Rib fractures puncturing the lung or vessels B) Blunt trauma to the abdomen C) Penetrating injury to the neck D) Head injury with skull fracture Answer: A
Explanation: Rib fractures can puncture the lung or intercostal vessels, leading to blood accumulation in the pleural space. Question 32. During secondary assessment, what does the SAMPLE history acronym stand for? A) Symptoms, Allergies, Medications, Past medical history, Last oral intake, Events leading to injury or illness B) Signs, Allergies, Medical history, Past surgeries, Last meal, Environment C) Symptoms, Antibiotics, Medical devices, Past injuries, Last activity, Exposure D) Signs, Allergies, Medications, Last seen normal, Events, Labs Answer: A Explanation: SAMPLE helps gather pertinent patient history during secondary assessment. Question 33. Which of the following is a contraindication for using an oropharyngeal airway? A) Unresponsive patient with no gag reflex B) Conscious patient with intact gag reflex
B) Remove any protruding bone fragments C) Immediately apply a tourniquet D) Pour antiseptic directly into the wound Answer: A Explanation: Covering with a sterile dressing and immobilization minimizes bleeding and infection risk. Question 36. Which vital sign change is most indicative of neurogenic shock? A) Tachycardia and hypertension B) Bradycardia and hypotension C) Elevated temperature and tachypnea D) Fever and increased blood pressure Answer: B Explanation: Neurogenic shock involves vasodilation and loss of sympathetic tone, leading to bradycardia and hypotension. Question 37. What is the most common cause of an airway obstruction in a conscious choking adult? A) Swallowed foreign object or food
