What is the purpose of an escharotomy in burn management?
- A. To relieve pressure and improve circulation in burn injuries
- B. To remove necrotic tissue from a wound
- C. To prevent infection in burn injuries
- D. To remove excess fluid from burn wounds
Correct Answer: A
Rationale: An escharotomy is performed to relieve pressure in areas affected by deep burns and improve circulation. This procedure involves making incisions through the eschar (burned and dead tissue) to release constricting tissue and allow for the return of blood flow. Choice B is incorrect because the removal of necrotic tissue is typically done through debridement, not escharotomy. Choice C is incorrect because preventing infection in burn injuries is usually achieved through proper wound care and antibiotic therapy, not escharotomy. Choice D is incorrect because removing excess fluid from burn wounds is managed through methods like fluid resuscitation and monitoring, not escharotomy.

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 dietary recommendations should be provided for a patient with pre-dialysis end-stage kidney disease?
- A. Reduce phosphorus intake to 700 mg/day
- B. Increase sodium intake
- C. Restrict protein intake to 0.55-0.60 g/kg/day
- D. Limit potassium-rich foods
Correct Answer: A
Rationale: The correct recommendation for a patient with pre-dialysis end-stage kidney disease is to reduce phosphorus intake to 700 mg/day. Excessive phosphorus can be harmful to individuals with kidney disease as the kidneys may not be able to effectively remove it from the body. Choices B, C, and D are incorrect. Increasing sodium intake is generally not recommended for patients with kidney disease as it can lead to fluid retention and high blood pressure. Restricting protein intake is important in later stages of kidney disease, but for pre-dialysis end-stage kidney disease, protein intake should be individualized based on the patient's condition. Limiting potassium-rich foods is more relevant for patients with advanced kidney disease or those on dialysis, as impaired kidney function can lead to high potassium levels in the blood.
What is the priority nursing intervention for a patient admitted with possible acute coronary syndrome?
- A. Administer sublingual nitroglycerin
- B. Obtain cardiac enzymes
- C. Get IV access
- D. Auscultate heart sounds
Correct Answer: A
Rationale: The correct answer is to administer sublingual nitroglycerin. This intervention is a priority for a patient with possible acute coronary syndrome because nitroglycerin helps vasodilate coronary arteries, increase blood flow to the heart muscle, relieve chest pain, and reduce cardiac workload. Obtaining cardiac enzymes (choice B) is important for diagnosing myocardial infarction but is not the initial priority. Getting IV access (choice C) is essential for medication administration and fluid resuscitation but is not the priority over administering nitroglycerin. Auscultating heart sounds (choice D) is a routine assessment but does not address the immediate need to relieve chest pain and improve blood flow to the heart in acute coronary syndrome.
What are the expected findings in a patient with hypokalemia?
- A. Cardiac dysrhythmias
- B. Seizures and confusion
- C. Bradycardia
- D. Muscle weakness
Correct Answer: A
Rationale: The correct answer is A: Cardiac dysrhythmias. Hypokalemia is commonly associated with cardiac dysrhythmias due to the role potassium plays in maintaining proper electrical conduction in the heart. Choices B, C, and D are incorrect. While hypokalemia can lead to muscle weakness, the most critical and life-threatening manifestation is cardiac dysrhythmias. Seizures and confusion are more commonly associated with other electrolyte imbalances, such as hyponatremia. Bradycardia is not a typical finding in hypokalemia, as it tends to cause tachycardia or other arrhythmias.
A nurse administers insulin for a misread glucose level. What should the nurse monitor for?
- A. Monitor for hypoglycemia
- B. Monitor for hyperglycemia
- C. Monitor for hyperkalemia
- D. Document the incident
Correct Answer: A
Rationale: When a nurse administers insulin for a misread glucose level, they should monitor for hypoglycemia. Insulin lowers blood sugar levels, so the patient may experience hypoglycemia if given insulin unnecessarily. Monitoring for hypoglycemia involves observing for symptoms such as shakiness, sweating, dizziness, confusion, and palpitations. Choices B and C are incorrect because administering insulin for a misread glucose level would lower blood sugar levels, resulting in hypoglycemia, not hyperglycemia or hyperkalemia. Choice D is not the immediate priority; the focus should be on patient safety and monitoring for potential adverse effects of the unnecessary insulin.
