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 client is admitted to the emergency department with a suspected myocardial infarction (MI). The nurse should prepare the client for which immediate diagnostic test?

• A. Chest x-ray
• B. Electrocardiogram (ECG)
• C. Echocardiogram
• D. Coronary angiography

Correct answer: B

Rationale: An Electrocardiogram (ECG) is the most immediate and essential test to diagnose a myocardial infarction (MI) and assess the extent of heart damage. An ECG can quickly identify changes in the heart's electrical activity, allowing prompt initiation of appropriate interventions. A chest x-ray (Choice A) may show other conditions affecting the heart, but it is not the immediate test of choice for diagnosing an MI. An echocardiogram (Choice C) and coronary angiography (Choice D) are valuable in further assessing cardiac function and anatomy post-MI but are not the first-line diagnostic tests due to their time-consuming nature compared to an ECG.

3. A client has a new prescription for furosemide. Which of the following statements should the nurse include in the teaching?

• A. Take the medication in the morning.
• B. Monitor for muscle weakness.
• C. Eat foods high in potassium.
• D. Expect weight gain.

Correct answer: C

Rationale: The correct statement that the nurse should include in the teaching for a client prescribed furosemide is to eat foods high in potassium. Furosemide can lead to potassium depletion (hypokalemia) due to increased urine output. Consuming potassium-rich foods like bananas, oranges, spinach, and potatoes can help prevent this electrolyte imbalance. Choices A, B, and D are incorrect because taking furosemide in the morning, monitoring for muscle weakness, and expecting weight gain are not directly related to the potential side effects or necessary dietary adjustments when taking furosemide.

4. While assessing a client taking propranolol, which finding should the nurse report to the provider?

• A. Bradycardia
• B. Dry mouth
• C. Constipation
• D. Increased appetite

Correct answer: A

Rationale: Bradycardia is a significant side effect of propranolol, a beta-blocker that slows the heart rate. It indicates potential cardiovascular complications and should be reported promptly to the healthcare provider for further evaluation and management. Dry mouth, constipation, and increased appetite are common side effects of various medications but are not directly associated with propranolol's mechanism of action.

5. A client has a new prescription for albuterol. Which of the following instructions should the nurse include?

• A. Use the inhaler every 4 hours around the clock.
• B. Shake the inhaler well before use.
• C. Rinse your mouth with water after each use.
• D. Use the inhaler while lying down.

Correct answer: B

Rationale: Shaking the inhaler well before use is crucial as it helps ensure proper mixing of the medication, which is essential for effective delivery of the drug to the lungs. This step is important for optimal therapeutic effects of albuterol inhalation. Choices A, C, and D are incorrect. Using the inhaler every 4 hours around the clock without specifying a maximum number of doses can lead to overuse. Rinsing the mouth with water after each use is typically advised for inhaled corticosteroids to reduce the risk of oral thrush, not for albuterol. Using the inhaler while lying down is not recommended as it may lead to improper medication delivery to the lungs.
