1. The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?
- A. Tall, peaked T waves
- B. ST-segment depression
- C. Prolonged P-R interval
- D. Widening of the QRS complex
Correct answer: B
Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.
2. A healthcare professional is assessing a client who has a new prescription for furosemide. Which of the following findings should the healthcare professional report to the provider?
- A. Weight gain
- B. Dry cough
- C. Hypokalemia
- D. Increased appetite
Correct answer: C
Rationale: The correct answer is C: Hypokalemia. Hypokalemia is a common electrolyte imbalance associated with furosemide use due to its diuretic effect, which can lead to potassium loss. It is crucial to report hypokalemia promptly to the provider as it can result in serious complications such as cardiac arrhythmias. Monitoring and managing potassium levels are essential in patients taking furosemide to prevent adverse effects related to electrolyte imbalances. Choices A, B, and D are incorrect findings to report in a client prescribed furosemide. Weight gain is not typically associated with furosemide use, a dry cough is more commonly linked to ACE inhibitors, and increased appetite is not a common adverse effect of furosemide.
3. The healthcare provider is monitoring a client following cardioversion. Which observation should be of the highest priority to the healthcare provider?
- A. Blood pressure
- B. Status of airway
- C. Oxygen flow rate
- D. Level of consciousness
Correct answer: B
Rationale: The status of the airway is the highest priority following cardioversion as it ensures proper oxygenation and helps prevent complications such as airway obstruction and respiratory distress. Maintaining a patent airway is crucial for the client's respiratory function and overall well-being immediately after cardioversion. Monitoring the airway ensures that the client can breathe effectively and minimizes the risk of hypoxia and other serious respiratory issues. While blood pressure, oxygen flow rate, and level of consciousness are also important parameters to monitor, they are secondary to ensuring a clear and patent airway for adequate oxygenation.
4. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?
- A. Blood glucose
- B. Serum sodium
- C. Serum potassium
- D. Blood urea nitrogen (BUN)
Correct answer: C
Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.
5. A client who has been taking prednisone is being assessed by a nurse. Which of the following findings should the nurse report to the provider?
- A. Weight gain
- B. Hyperglycemia
- C. Dry mouth
- D. Increased appetite
Correct answer: B
Rationale: Hyperglycemia is a significant finding in a client taking prednisone as it indicates the medication's impact on glucose metabolism. Prednisone can lead to increased blood sugar levels, which can be detrimental, especially in clients with diabetes or predisposition to hyperglycemia. Reporting hyperglycemia promptly to the healthcare provider is crucial for further evaluation and management to prevent complications. Choices A, C, and D are common side effects of prednisone but are not as concerning as hyperglycemia, which requires immediate attention to avoid potential adverse effects.
