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 should a healthcare professional do if a patient experiences abdominal cramping during enema administration?
- A. Lower the height of the enema solution container
- B. Stop the procedure and remove the tubing
- C. Continue the enema at a slower rate
- D. Increase the flow of the enema solution
Correct Answer: A
Rationale: When a patient experiences abdominal cramping during enema administration, the healthcare professional should lower the height of the enema solution container. This action helps relieve the cramping by slowing down the flow of the enema solution, making it more comfortable for the patient. Stopping the procedure and removing the tubing (Choice B) may be necessary in some cases, but it should not be the first step when cramping occurs. Continuing the enema at a slower rate (Choice C) may exacerbate the cramping, so it is not the best course of action. Increasing the flow of the enema solution (Choice D) will likely worsen the cramping and should be avoided.
What is the first medication to give to a patient with wheezing due to an allergic reaction?
- A. Albuterol 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 via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it is a fast-acting bronchodilator that helps to quickly open the airways, providing immediate relief of symptoms. Choice B, Methylprednisolone 100 mg IV, is a corticosteroid used for its anti-inflammatory effects but is not the initial medication for acute wheezing in an allergic reaction. Choice C, Cromolyn 20 mg via nebulizer, is a mast cell stabilizer that can be used for prevention but is not the first choice for acute symptom relief. Choice D, Aminophylline 500 mg IV, is a bronchodilator with a narrow therapeutic window and more side effects compared to Albuterol, making it a less preferred option as the initial treatment.
During an escharotomy on a patient with a burn injury, what is the purpose of this procedure?
- A. To release pressure and improve circulation in the affected area
- B. To remove dead tissue from the burn area
- C. To improve breathing by reducing skin tightness
- D. To prevent infection in the burned area
Correct Answer: A
Rationale: Corrected Question: During an escharotomy on a patient with a burn injury, the purpose of this procedure is to release pressure and improve circulation in the affected area. This intervention is crucial in severe burns where the formation of eschar (dead tissue) can lead to increased pressure, compromising circulation and potentially causing further tissue damage. Choices B, C, and D are incorrect because escharotomy specifically aims to address pressure and circulation issues in severe burn injuries, rather than removing dead tissue, improving breathing, or preventing infection.
What ECG changes are seen in hypokalemia?
- A. Flattened T waves on the ECG
- B. Elevated ST segments on the ECG
- C. Widened QRS complex
- D. Prominent U waves on the ECG
Correct Answer: A
Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.
What are the characteristics of a thrombotic stroke?
- A. Gradual onset over minutes to hours
- B. Numbness on one side of the body
- C. Associated with a loss of consciousness
- D. Associated with seizures and convulsions
Correct Answer: A
Rationale: The correct answer is A. Thrombotic strokes typically have a gradual onset over minutes to hours as they result from a clot obstructing blood flow. Choice B, numbness on one side of the body, is more commonly associated with an ischemic stroke rather than specifically a thrombotic stroke. Choice C, loss of consciousness, is not a defining characteristic of a thrombotic stroke. Choice D, seizures and convulsions, are more commonly seen in hemorrhagic strokes rather than thrombotic strokes.
