Question 1. Which of the following structures is part of the upper airway? A) Trachea B) Larynx C) Nasopharynx D) Bronchi Answer: C Explanation: The nasopharynx is part of the upper airway, involved in conducting air from the nose to the oropharynx, whereas trachea, larynx, and bronchi are part of the lower airway. Question 2. Gas exchange primarily occurs in which part of the respiratory system? A) Trachea
B) Alveoli C) Larynx D) Bronchioles Answer: B Explanation: Gas exchange occurs in the alveoli, where oxygen diffuses into the blood and carbon dioxide diffuses out, due to their thin walls and large surface area. Question 3. Which neurological structure primarily controls the respiratory rate? A) Cerebellum B) Medulla oblongata C) Cerebral cortex
Explanation: The head-tilt/chin-lift maneuver helps open the airway by preventing the tongue from obstructing the oropharynx, facilitating ventilation. Question 5. Which airway device is most appropriate for a patient with a gag reflex? A) Oropharyngeal airway (OPA) B) Nasopharyngeal airway (NPA) C) Endotracheal tube D) Laryngeal mask airway (LMA) Answer: B Explanation: The nasopharyngeal airway (NPA) can be used in patients with a gag reflex, as it is less likely to induce vomiting or airway obstruction compared to OPA.
Question 6. Capnography is used to confirm the placement of which device? A) Nasal cannula B) Endotracheal tube C) Non-rebreather mask D) Bag-valve mask Answer: B Explanation: Capnography measures exhaled CO2 to confirm proper placement of an endotracheal tube, ensuring the tube is in the trachea rather than the esophagus. Question 7. Which oxygen delivery device provides the highest concentration of oxygen?
C) Manual ventilation with the patient’s mouth open only D) Ventilation at 20-30 breaths per minute to ensure adequate oxygenation Answer: B Explanation: The two-person BVM technique improves mask seal and ventilation efficiency, with a rate of 10-12 breaths per minute to prevent hyperventilation. Question 9. Which of the following best describes a normal sinus rhythm on an ECG? A) Irregular rhythm with no P waves B) Regular rhythm with P waves before each QRS complex C) Rapid ventricular rate with wide QRS complexes D) Absent P waves with flat baseline
Answer: B Explanation: Normal sinus rhythm is characterized by a regular rhythm with a P wave before each QRS complex, indicating proper atrial depolarization. Question 10. Which arrhythmia is characterized by a rapid, disorganized electrical activity leading to no effective heartbeat? A) Ventricular tachycardia B) Ventricular fibrillation C) Asystole D) Sinus tachycardia Answer: B
Question 12. Which type of shock results from inadequate blood volume due to hemorrhage or dehydration? A) Cardiogenic shock B) Hypovolemic shock C) Obstructive shock D) Distributive shock Answer: B Explanation: Hypovolemic shock occurs when blood volume decreases significantly, impairing perfusion and leading to tissue hypoxia. Question 13. Which of the following is a common sign of congestive heart failure? A) Sudden hypertension
B) Pulmonary edema with crackles on auscultation C) Elevated blood glucose D) Bradycardia with hypotension Answer: B Explanation: Pulmonary edema caused by CHF leads to crackles or rales on auscultation, due to fluid accumulation in the lungs. Question 14. In cardiac arrest management, what is the recommended compression-to-ventilation ratio for adult patients when providing CPR with a rescue device? A) 15: B) 30: C) 10:
Explanation: Hemorrhagic stroke results from bleeding into brain tissue, often caused by vessel rupture, necessitating rapid recognition and management. Question 16. Which is a common cause of hypoglycemia in diabetic patients? A) Excess insulin administration B) Infection C) Stress D) Hyperglycemia Answer: A Explanation: Excess insulin can lower blood glucose levels too much, resulting in hypoglycemia, which requires prompt treatment with glucose.
Question 17. Which gastrointestinal emergency presents with painless, bright red blood in the stool? A) Hemorrhoids B) Gastrointestinal bleeding C) Appendicitis D) Cholecystitis Answer: B Explanation: Bright red blood in the stool indicates lower gastrointestinal bleeding, which can be life-threatening and requires immediate care. Question 18. Anaphylaxis is characterized by which of the following? A) Gradual onset and localized swelling
C) Meningitis D) Tuberculosis Answer: C Explanation: Meningitis is caused by Neisseria meningitidis or other bacteria, leading to inflammation of the meninges and requiring urgent care. Question 20. In sickle cell crisis, what is the primary concern? A) Excessive bleeding B) Obstruction of blood flow due to sickled cells C) Excessive clotting D) Fluid overload Answer: B
Explanation: Sickle cell crisis involves sickled cells occluding small blood vessels, causing ischemia and pain, often requiring hydration and pain management. Question 21. Which heat emergency is characterized by altered mental status, hot dry skin, and potential seizures? A) Heat cramps B) Heat exhaustion C) Heat stroke D) Heat rash Answer: C Explanation: Heat stroke involves core temperature >104°F, altered mental status, and dry or moist skin, demanding immediate cooling measures.
B) Hypoxia leading to brain injury C) Hyperthermia D) Hyperglycemia Answer: B Explanation: Near-drowning causes hypoxia due to airway obstruction or respiratory failure, risking brain damage. Question 24. Carbon monoxide poisoning primarily affects which system? A) Nervous system B) Cardiovascular system C) Hematologic system D) Respiratory system
Answer: B Explanation: CO binds to hemoglobin, reducing oxygen delivery and leading to hypoxia, primarily affecting the cardiovascular system. Question 25. Which of the following overdoses is most associated with respiratory depression? A) Opioids B) Stimulants C) Anticholinergics D) Beta-blockers Answer: A Explanation: Opioids depress the respiratory centers in the brain, leading to hypoventilation and potential respiratory arrest.
