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. The client has been prescribed atorvastatin (Lipitor) for hyperlipidemia. Which instruction should the nurse provide to the client?

• A. Take the medication in the morning with breakfast.
• B. Avoid drinking grapefruit juice while taking this medication.
• C. Increase your intake of dietary fiber while on this medication.
• D. Avoid eating foods high in potassium.

Correct answer: B

Rationale: The correct instruction for the nurse to provide to the client prescribed atorvastatin (Lipitor) for hyperlipidemia is to avoid drinking grapefruit juice while taking this medication. Grapefruit juice can interfere with the metabolism of atorvastatin, leading to an increased risk of side effects. It is crucial for the client to adhere to this instruction to ensure the effectiveness and safety of the treatment. Choices A, C, and D are incorrect because taking the medication with breakfast, increasing dietary fiber intake, and avoiding foods high in potassium are not specific instructions related to atorvastatin therapy for hyperlipidemia.

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. When assisting a hospitalized client newly diagnosed with coronary artery disease (CAD) to make appropriate selections from the dietary menu, which meal should the nurse encourage the client to select?

• A. Sausage, pancakes, and toast
• B. Broccoli, buttered rice, and grilled chicken
• C. Hamburger, baked apples, and avocado salad
• D. Fresh strawberries, steamed vegetables, and baked fish

Correct answer: D

Rationale: The correct choice is D: Fresh strawberries, steamed vegetables, and baked fish. This meal is low in saturated fats and cholesterol, which is suitable for a client with CAD. It aligns with dietary recommendations to support heart health and manage CAD. Choices A, B, and C are less appropriate as they contain higher levels of saturated fats and cholesterol, which are not ideal for individuals with CAD.

5. A healthcare professional is assessing a client who has a new prescription for levothyroxine. Which of the following findings should the healthcare professional report to the provider?

• A. Weight gain
• B. Increased heart rate
• C. Heat intolerance
• D. Elevated blood pressure

Correct answer: C

Rationale: The correct answer is C: Heat intolerance. Heat intolerance is a concerning sign of levothyroxine toxicity and should be reported to the provider promptly. Levothyroxine is a medication used to treat hypothyroidism by supplementing the body's thyroid hormones. When a client experiences heat intolerance, it can indicate that the dose of levothyroxine is too high, leading to hyperthyroidism symptoms. Weight gain, increased heart rate, and elevated blood pressure are not typically associated with levothyroxine toxicity; instead, they are more commonly seen in conditions like hypothyroidism.
