1. What are the adverse effects of radiation after a mastectomy?

• A. S3 heart sound, fatigue
• B. Pulselessness in the affected extremity
• C. SOB and JVD
• D. Localized pain, swelling, erythema

Correct answer: A

Rationale: The correct answer is A: S3 heart sound, fatigue. Radiation after a mastectomy can lead to fatigue and symptoms of heart failure, such as the presence of an S3 heart sound. Choices B, C, and D are incorrect. Pulselessness in the affected extremity would be more relevant to vascular complications, shortness of breath (SOB) and jugular venous distention (JVD) could indicate cardiac or respiratory issues unrelated to radiation, and localized pain, swelling, and erythema are more characteristic of a local inflammatory response rather than the systemic effects of radiation post-mastectomy.

2. A nurse is caring for a client who has dehydration. The client has a peripheral IV and a prescription for an infusion of 0.9% sodium chloride 1,000 mL with 40 mEq potassium chloride to infuse over 1 hr. Which of the following actions should the nurse take first?

• A. Teach the client to report findings of IV extravasation
• B. Evaluate the patency of the IV
• C. Consult with the pharmacist about the prescription
• D. Verify the prescription with the provider

Correct answer: D

Rationale: The nurse's priority action should be to verify the prescription with the provider. This is crucial to prevent injury from fluid volume overload and rapid potassium infusion. Verifying the prescription ensures that the correct solution, rate, and additives are ordered according to the client's condition. While evaluating the patency of the IV is important, verifying the prescription takes precedence to ensure patient safety. Consulting with the pharmacist can be beneficial, but confirming the prescription with the provider is the immediate priority. Teaching the client about IV extravasation is important but is not the first action the nurse should take in this scenario.

3. What ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.

4. What is an escharotomy, and why is it performed?

• 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 remove fluid from a burn wound

Correct answer: A

Rationale: An escharotomy is a surgical procedure performed to relieve pressure and improve circulation in areas affected by deep burns. Choice A is the correct answer because the primary goal of an escharotomy is to prevent compartment syndrome caused by increased pressure within the affected tissues. Choices B, C, and D are incorrect because an escharotomy is not primarily performed to reduce pain, remove necrotic tissue, or drain fluid from a burn wound, but to address the specific issue of compromised blood flow and pressure within deep burn injuries.

5. What is the preferred electrical intervention for a patient with ventricular tachycardia and a pulse?

• A. Synchronized cardioversion
• B. Defibrillation
• C. Medication administration
• D. Pacing

Correct answer: A

Rationale: In a patient with ventricular tachycardia and a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat unstable tachyarrhythmias like ventricular tachycardia with a pulse. Choice B, defibrillation, is used for pulseless ventricular tachycardia or ventricular fibrillation. Choice C, medication administration, may not provide immediate correction for unstable ventricular tachycardia. Choice D, pacing, is not the first-line treatment for ventricular tachycardia with a pulse.
