What is an escharotomy and when is it performed?
- A. A surgical incision to release pressure in burn injuries
- B. A procedure to remove dead tissue from wounds
- C. An incision to improve circulation in tight skin after burns
- D. A procedure to remove excess fluid from the chest
Correct Answer: A
Rationale: An escharotomy is a surgical incision made to release pressure in a part of the body that has a deep burn and excessive swelling. This procedure is crucial in preventing further damage due to restricted blood flow and compromised circulation. Choice B is incorrect because it describes debridement, which is the removal of dead tissue from wounds. Choice C is incorrect as it does not specifically address the purpose of relieving pressure in burn injuries. Choice D is incorrect as it describes a procedure more related to thoracentesis, which is the removal of excess fluid from the chest, typically the pleural space.

What signs indicate increased intracranial pressure (IICP)?
- A. Restlessness, irritability, and confusion
- B. Sudden onset of seizures
- C. Bradycardia and altered pupil response
- D. Loss of consciousness
Correct Answer: A
Rationale: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These symptoms occur due to the brain's increased pressure within the skull. Sudden onset of seizures (Choice B) is not typically associated with increased intracranial pressure. Bradycardia and altered pupil response (Choice C) are signs of advanced or worsening IICP. Loss of consciousness (Choice D) is a late sign of increased intracranial pressure.
What are the signs and symptoms of Increased Intracranial Pressure (IICP)?
- A. Irritability, confusion, restlessness
- B. Fatigue and SOB
- C. Changes in pupillary response
- D. Elevated blood pressure
Correct Answer: A
Rationale: The correct answer is A: Irritability, confusion, restlessness. These are common signs of Increased Intracranial Pressure (IICP) as they result from the increased pressure on brain tissue. Choices B, C, and D are incorrect. Fatigue and shortness of breath (SOB) are not typical symptoms of IICP. Changes in pupillary response can be seen in other conditions but are not specific to IICP. Elevated blood pressure is not a common sign of IICP.
What is the first medication to give to a patient with an allergic reaction causing wheezing?
- A. Albuterol 3 ml via nebulizer
- B. Methylprednisolone 100 mg IV
- C. Cromolyn 20 mg via nebulizer
- D. Aminophylline 500 mg IV
Correct Answer: A
Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is a fast-acting bronchodilator that helps relieve wheezing by relaxing the muscles in the airways, making it the first-line treatment for wheezing caused by bronchospasms in allergic reactions. Methylprednisolone (Choice B) is a corticosteroid used for its anti-inflammatory properties and is typically given after bronchodilators. Cromolyn (Choice C) is a mast cell stabilizer that is used for the prevention of asthma symptoms, not for immediate relief. Aminophylline (Choice D) is a bronchodilator that is less commonly used nowadays due to its narrow therapeutic window and potential for toxicity.
The nurse misread a patient's glucose as 210 mg/dL instead of 120 mg/dL and administered the insulin dose for a reading over 200 mg/dL. What is the priority action?
- A. Administer glucose IV
- B. Monitor for hyperglycemia
- C. Monitor for hypoglycemia
- D. Document the incident
Correct Answer: C
Rationale: The priority action is to monitor the patient for signs of hypoglycemia as the nurse administered excess insulin due to misreading the glucose level. Administering glucose IV (Choice A) is not the immediate priority when dealing with hypoglycemia. Monitoring for hyperglycemia (Choice B) is not the correct action as the insulin was administered for a higher glucose reading. Documenting the incident (Choice D) is important but not the priority when the patient's safety is at risk due to possible hypoglycemia.
What are the expected manifestations in a patient experiencing a thrombotic stroke?
- A. Sudden numbness or loss of function on one side of the body
- B. Sudden loss of consciousness and seizure
- C. Gradual onset of difficulty speaking
- D. Loss of sensation in the affected limb
Correct Answer: A
Rationale: The correct manifestation in a patient experiencing a thrombotic stroke is sudden numbness or loss of function on one side of the body. This is due to the blockage of a blood vessel by a clot, leading to a lack of blood flow to a specific part of the brain. Choices B, C, and D are incorrect. Sudden loss of consciousness and seizure are more commonly associated with hemorrhagic strokes. Gradual onset of difficulty speaking is often seen in ischemic strokes affecting language areas, not specifically in thrombotic strokes. Loss of sensation in the affected limb is more indicative of sensory nerve damage rather than the motor deficits seen in thrombotic strokes.
