2. The hypodermis (subcutaneous layer) primarily contains which type of tissue?. Keratinized epithelial tissue. Dense connective tissue. Adipose tissue. Cartilage.

3. Intradermal injections are typically administered at which angle?. 15 degrees. 45 degrees. 90 degrees. 120 degrees.

4. Subcutaneous injections are generally administered at which angle?. 15 degrees. 25 degrees. 4590 degrees. 120 degrees.

5. Intramuscular injections should be administered at which angle?. 15 degrees. 45 degrees. 60 degrees. 90 degrees.

6. Which intramuscular injection site is considered safest for adults due to absence of major nerves and blood vessels?. Deltoid. Ventrogluteal. Dorsogluteal. Abdominal.

7. The Z track injection method is primarily used for which purpose?. Speed medication absorption. Reduce medication pain. Prevent medication leakage into subcutaneous tissue. Improve venous access.

8. Which medication administration scenario most commonly requires the Z track method?. Insulin injection. Iron injection. Intradermal allergy test. Heparin injection.

9. During an anaphylactic reaction, the first-line medication administered via auto injector is: Diphenhydramine. Epinephrine. Prednisone. Albuterol.

10. After administering an epinephrine autoIinjector, the patient should: Lie down and rest. Call emergency services immediately. Drink fluids. Take oral antihistamines.

11. Which electrolyte abnormality is commonly associated with severe burn injuries due to cellular destruction?. Hypokalemia. Hyperkalemia. Hyponatremia. Hypercalcemia.

12. The most critical phase of burn injury management occurs within: First 6 hours. First 12 hours. First 24 hours. First 72 hours.

13. Which type of burn carries the highest risk of deep muscle or cardiac damage?. Thermal burn. Chemical burn. Electrical burn. Radiation burn.

14. A burn patient with facial burns and singed nasal hairs should be assessed immediately for: Kidney failure. Airway compromise. Infection. Dehydration.

15. First degree burns involve which skin layer?. Dermis. Epidermis. Subcutaneous tissue. Muscle.

16. A painless burn with leathery, waxy skin indicates: First degree burn. Second degree burn. Third degree burn. Superficial burn.

17. According to the Rule of Nines, the anterior trunk represents what percentage of total body surface area in adults?. 9%. 18%. 36%. 45%.

18. Each arm in the adult Rule of Nines accounts for approximately: 4.5%. 9%. 18%. 36%.

19. Carbon monoxide poisoning causes hypoxia primarily because CO: Blocks alveoli. Destroys red blood cells. Binds hemoglobin more strongly than oxygen. Decreases respiratory rate.

20. A misleading clinical finding in carbon monoxide poisoning is: Low pulse rate. Normal pulse oximetry reading. Cyanosis. Bradycardia.

21. Which intervention should NOT be performed on a burn injury at the scene?. Cooling the burn with water. Removing patient from heat source. Applying ice directly to the skin. Covering the wound with a clean cloth.

22. What is the first priority in burn management according to the ABC approach?. Circulation. Airway. Pain control. Nutrition.

23. What type of oxygen delivery is recommended for suspected inhalation injury?. Nasal cannula. Simple mask. Non rebreather mask with 100% oxygen. Venturi mask.

24. The Parkland formula calculates burn fluid requirements using which components?. Age, weight, burn depth. Weight, TBSA burned, constant factor. Height, TBSA burned, age. Blood pressure and TBSA.

25. When administering fluids based on the Parkland formula, how much of the total volume should be given in the first 8 hours?. One quarter. One half. ThreeIquarters. All.

26. Which IV fluid is considered the gold standard for burn resuscitation?. Dextrose 5%. Lactated Ringer's. Hypertonic saline. Albumin.

27. The most reliable indicator that fluid resuscitation is adequate in a burn patient is: Heart rate. Blood pressure. Urine output. Temperature.

28. The target urine output for adult burn patients is approximately: 1020 mL/hr. 2030 mL/hr. 3050 mL/hr. 6080 mL/hr.

29. Why are burn patients placed in protective (reverse) isolation?. Prevent dehydration. Prevent infection due to compromised skin barrier. Improve oxygenation. Reduce pain.

30. In severe burns, enteral feeding is preferred over parenteral nutrition because it: Prevents aspiration. Maintains gut integrity and reduces sepsis risk. Provides more calories. Requires less monitoring.
