Nursing Elites

1. What ECG changes are expected in a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Widened QRS complexes
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.

2. 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.

3. A patient reports abdominal cramping after enema administration. What action should the nurse take to relieve the discomfort?

• A. Lower the height of the solution container
• B. Increase the flow of enema solution
• C. Remove the enema tubing
• D. Stop the procedure

Correct answer: A

Rationale: The correct action to relieve abdominal cramping after enema administration is to lower the height of the solution container. This adjustment slows down the flow rate of the enema solution, which can help reduce discomfort by decreasing the pressure on the patient's abdomen. Increasing the flow of the enema solution (Choice B) would exacerbate the cramping by introducing more solution quickly. Removing the enema tubing (Choice C) is not necessary to address the cramping, and stopping the procedure (Choice D) may not be needed if adjusting the height of the solution container can resolve the issue.

4. If a nurse misread a glucose reading as 210 mg/dL instead of 120 mg/dL and administered insulin, what should the nurse monitor for?

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

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. In this scenario, the nurse administered insulin based on an incorrect glucose reading, which could lead to a drop in blood sugar levels. Monitoring for hypoglycemia is crucial to prevent any adverse effects on the patient's health. Choice B, monitoring for hyperglycemia, is incorrect as the administration of insulin can lead to low blood sugar levels, not high. Choice C, administering glucose IV, is not the immediate action needed as monitoring for hypoglycemia comes first. Choice D, documenting the incident, is important but not the initial priority when patient safety is at risk.

5. A patient is admitted with an air leak in a chest tube system. What action should the nurse take?

• A. Tighten the connections of the chest tube system
• B. Continue monitoring the patient
• C. Replace the chest tube system
• D. Clamp the chest tube

Correct answer: A

Rationale: When caring for a patient with an air leak in the chest tube system, the nurse should tighten the connections of the chest tube system. This action can help resolve the air leak by ensuring there are no loose connections or leaks in the system. Continuing to monitor the patient (Choice B) is important, but addressing the air leak is a priority. Replacing the chest tube system (Choice C) may not be necessary if tightening the connections resolves the issue. Clamping the chest tube (Choice D) is not appropriate as it can lead to tension pneumothorax.
