1. What is the purpose of an escharotomy?

• A. To relieve pressure and improve circulation in burn injuries
• B. To reduce pain in the affected area
• C. To remove necrotic tissue from a wound
• D. To prevent infection from spreading

Correct answer: A

Rationale: An escharotomy is performed to relieve pressure and improve circulation in areas affected by deep burns. This procedure helps prevent complications such as compartment syndrome by releasing the constricting eschar. Choice B is incorrect because while pain relief may be a secondary outcome of the procedure, the primary purpose is to address pressure and circulation issues. Choice C is incorrect as an escharotomy specifically focuses on releasing pressure, not removing necrotic tissue. Choice D is incorrect as the primary goal of an escharotomy is not to prevent infection but rather to address the immediate issues related to deep burn injuries.

2. What medication should be administered first for wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn via nebulizer
• C. Methylprednisolone IV
• D. Aminophylline 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 quickly opens the airways by relaxing the muscles around the airways. Cromolyn (choice B) is used more for prevention rather than immediate relief of symptoms. Methylprednisolone (choice C) and Aminophylline (choice D) are not the first-line treatments for acute wheezing due to an allergic reaction.

3. What are the expected manifestations of a thrombotic stroke?

• A. Gradual loss of function on one side of the body
• B. Loss of sensation in the affected extremity
• C. Sudden loss of consciousness
• D. Seizures and convulsions

Correct answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. Thrombotic strokes are caused by a clot forming in a blood vessel supplying the brain, leading to a gradual onset of symptoms due to impaired blood flow to specific brain regions. Choices B, C, and D are incorrect because loss of sensation, sudden loss of consciousness, seizures, and convulsions are not typically associated with thrombotic strokes. In a thrombotic stroke, the symptoms develop slowly over time, often over minutes to hours, and include manifestations such as weakness, numbness, or paralysis on one side of the body, along with other symptoms related to the affected brain area.

4. What are the expected findings in a patient experiencing hypokalemia?

• A. Flattened T waves on an ECG
• B. Elevated ST segments
• C. Prominent U waves
• D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.

5. A nurse misreads a glucose reading and administers insulin for a blood glucose of 210 instead of 120. What should the nurse monitor the patient for?

• A. Monitor for hyperglycemia
• B. Monitor for signs of hypoglycemia
• C. Administer glucose IV
• D. Document the incident

Correct answer: B

Rationale: The correct answer is B: Monitor for signs of hypoglycemia. The nurse should monitor the patient for hypoglycemia due to the administration of excess insulin. Administering insulin for a blood glucose level of 210 instead of 120 can lead to a rapid drop in blood sugar levels, causing hypoglycemia. Option A is incorrect as hyperglycemia is high blood sugar, which is unlikely in this scenario. Option C is incorrect as administering glucose IV would worsen the hypoglycemia. Option D is not the immediate priority; patient safety and monitoring for adverse effects take precedence.
