Nursing Elites

1. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?

• A. Tall, peaked T waves
• B. ST segment depressions
• C. Shortened P-R intervals
• D. Shortening of the QRS complex

Correct answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.

2. The nurse is preparing to administer an intravenous dose of potassium chloride to a client with hypokalemia. The nurse should monitor for which potential complication?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hypernatremia
• D. Hypercalcemia

Correct answer: A

Rationale: When administering potassium chloride to a client with hypokalemia, the nurse should monitor for hyperkalemia. Potassium chloride supplementation aims to increase potassium levels in individuals with hypokalemia. However, excessive administration can lead to hyperkalemia, which can be a serious and potentially life-threatening complication. Monitoring potassium levels is crucial to prevent this adverse outcome. Hypokalemia (Choice B) is the condition being treated, so it is not a complication of treatment. Hypernatremia (Choice C) refers to high sodium levels and is not directly related to the administration of potassium chloride. Hypercalcemia (Choice D) is an elevated calcium level and is not a common complication associated with potassium chloride administration in hypokalemia.

3. The nurse is preparing a client for discharge after a myocardial infarction (MI). Which instruction is most important for the nurse to reinforce with the client?

• A. Avoid engaging in sexual activity for at least 6 weeks.
• B. Engage in moderate physical activity daily.
• C. Take prescribed medications even if you feel well.
• D. Return to work only when medically cleared.

Correct answer: C

Rationale: The most critical instruction for a client after a myocardial infarction is to continue taking prescribed medications even if they feel well. This is essential in preventing another myocardial infarction or other complications. Discontinuing medications prematurely can be detrimental to the client's recovery and may increase the risk of further cardiovascular events. Choices A, B, and D are incorrect because engaging in sexual activity, physical activity, or returning to work are important aspects of the client's recovery, but not as crucial as ensuring medication compliance to prevent further cardiac issues.

4. A healthcare professional is assessing a client who has been taking levodopa/carbidopa for Parkinson's disease. Which of the following findings should the healthcare professional report to the provider?

• A. Dry mouth
• B. Urinary retention
• C. Bradykinesia
• D. Dizziness

Correct answer: C

Rationale: Bradykinesia is a cardinal symptom of Parkinson's disease characterized by slowness of movement. An increase in bradykinesia may indicate a decline in the client's condition and the need for adjustments in their medication regimen. Therefore, the healthcare professional should promptly report this finding to the provider for further evaluation and management. Choices A, B, and D are not directly related to the client's Parkinson's disease or the medication levodopa/carbidopa. Dry mouth is a common side effect of many medications, including anticholinergics, but not specifically levodopa/carbidopa. Urinary retention and dizziness are also not typically associated with levodopa/carbidopa use for Parkinson's disease.

5. A client with hypertension is prescribed metoprolol (Lopressor). The nurse should monitor the client for which side effect?

• A. Tachycardia
• B. Bradycardia
• C. Hypertension
• D. Hyperglycemia

Correct answer: B

Rationale: Metoprolol is a beta-blocker that works by slowing the heart rate. Therefore, the nurse should monitor the client for bradycardia, which is a potential side effect of metoprolol. Bradycardia refers to a heart rate that is slower than normal, and it can be a concern when administering medications like metoprolol that affect heart rate. Choices A, C, and D are incorrect as tachycardia (fast heart rate), hypertension (high blood pressure), and hyperglycemia (high blood sugar) are not typically associated with metoprolol use. In fact, metoprolol is used to treat hypertension and certain heart conditions by lowering heart rate and blood pressure.
