Nursing Elites

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 been taking digoxin. Which of the following findings should the healthcare professional report to the provider?

• A. Weight gain
• B. Dry cough
• C. Hypokalemia
• D. Bradycardia

Correct answer: D

Rationale: The correct answer is D: Bradycardia. Bradycardia is a significant finding associated with digoxin toxicity. Digoxin, a medication commonly used to treat heart conditions, can lead to bradycardia as a sign of toxicity. Bradycardia requires immediate attention and reporting to the healthcare provider for further evaluation and management to prevent serious complications. Choices A, B, and C are incorrect because weight gain, dry cough, and hypokalemia are not specific signs of digoxin toxicity. While weight gain can be a side effect of digoxin, it is not a classic sign of toxicity. Dry cough is more commonly associated with medications like ACE inhibitors, and hypokalemia can be a complication of digoxin therapy but is not a direct sign of toxicity.

3. A client is admitted to the hospital with a diagnosis of myocardial infarction (MI). Which diagnostic test is most likely to be ordered to confirm this diagnosis?

• A. Echocardiogram
• B. Electrocardiogram (ECG)
• C. Chest X-ray
• D. Complete blood count (CBC)

Correct answer: B

Rationale: An Electrocardiogram (ECG) is the primary diagnostic tool used to confirm a myocardial infarction. An ECG provides immediate information on cardiac function and can show characteristic changes indicative of a myocardial infarction, such as ST-segment elevation or depression. An echocardiogram (Choice A) is useful for assessing heart structure and function but is not typically used as the primary test for confirming an acute myocardial infarction. Chest X-ray (Choice C) may show certain changes in heart size or pulmonary congestion but is not the primary diagnostic test for MI. A Complete Blood Count (CBC) (Choice D) provides information about the cellular components of blood and is not specific to confirming a myocardial infarction.

4. 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.

5. The client with a new prescription for warfarin (Coumadin) is receiving teaching from the LPN/LVN. Which statement by the client indicates an understanding of the medication?

• A. I will avoid eating foods high in vitamin K, like spinach and broccoli.
• B. I will take aspirin instead of acetaminophen for headaches while on this medication.
• C. I can stop taking the medication once my symptoms improve.
• D. I will double my dose if I miss a dose to catch up.

Correct answer: A

Rationale: Clients prescribed with warfarin (Coumadin) need to maintain a consistent intake of vitamin K and avoid sudden increases in foods rich in vitamin K as it can interfere with the effectiveness of the medication. Choice A, 'I will avoid eating foods high in vitamin K, like spinach and broccoli,' is the correct statement indicating an understanding of the medication. This choice demonstrates knowledge of the importance of consistent vitamin K intake to prevent fluctuations in warfarin's effectiveness. Choices B, C, and D are incorrect. Choice B suggests a substitution that is not advised without consulting a healthcare provider. Choice C is incorrect as stopping warfarin suddenly can lead to serious health risks. Choice D is unsafe and incorrect since doubling the dose is not the correct action if a dose is missed.
