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. A nurse is caring for a client who has been experiencing repeated tonic-clonic seizures over the course of 30 minutes. After maintaining the client's airway and turning the client on their side, which of the following medications should the nurse administer?

A. Diazepam IV
B. Lorazepam PO
C. Diltiazem IV
D. Clonazepam PO

Correct answer: A

Rationale: In the scenario described, where the client has been experiencing repeated tonic-clonic seizures over an extended period, the priority is to administer a medication that can rapidly terminate the seizures. Diazepam is the medication of choice for status epilepticus due to its rapid onset of action within 10 minutes when administered intravenously. Lorazepam is also an option, but it is typically administered intravenously as well. Diltiazem is a calcium channel blocker used for conditions like hypertension and angina, not for seizures. Clonazepam, although used for seizures, is not the ideal choice in this acute situation due to its slower onset of action compared to benzodiazepines like diazepam and lorazepam.

3. 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.

4. A nurse is providing discharge teaching for a client who has COPD about nutrition. Which of the following instructions should the nurse include?

A. Eat three large meals daily
B. Consume high-calorie foods
C. Limit caffeinated drinks to two per day
D. Drink fluids during meal time

Correct answer: B

Rationale: The correct answer is B: 'Consume high-calorie foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach putting pressure on the diaphragm. Choice C is incorrect because caffeinated drinks can contribute to dehydration, which is not ideal for clients with COPD. Choice D is incorrect because drinking fluids during mealtime can cause bloating and early satiety, making it difficult for clients to consume enough calories.

5. A patient who experienced an acute episode of gastritis should avoid which type of foods?

A. Avoid foods high in potassium
B. Avoid foods high in sodium
C. Increase exercise
D. Drink milk as a snack

Correct answer: A

Rationale: Patients who have experienced an acute episode of gastritis should avoid foods high in potassium. Potassium-rich foods can irritate the gastric lining, exacerbating gastritis symptoms. Therefore, choices B, C, and D are incorrect. Avoiding foods high in sodium is beneficial for other health conditions like hypertension, increasing exercise is generally good for overall health but not specifically for gastritis management, and drinking milk may provide temporary relief for some but is not a definitive recommendation for gastritis management.
