Nursing Elites

1. A client with a history of angina is scheduled for an exercise electrocardiography (ECG) test. The nurse should explain that the purpose of this test is to evaluate which factor?

• A. The heart's response to physical stress
• B. The client's overall physical fitness
• C. The presence of electrolyte imbalances
• D. The effectiveness of anti-anginal medications

Correct answer: A

Rationale: An exercise electrocardiography (ECG) test is used to evaluate the heart's response to physical stress. During the test, the heart's electrical activity is monitored while the client exercises, helping to identify any areas of ischemia or abnormal rhythms. This test helps healthcare providers assess the heart's function and detect any potential issues related to angina or other cardiac conditions. Choice B, the client's overall physical fitness, is incorrect because the test primarily focuses on the heart's response to stress rather than the client's general physical fitness. Choice C, the presence of electrolyte imbalances, is incorrect as this test is not specifically designed to evaluate electrolyte levels. Choice D, the effectiveness of anti-anginal medications, is incorrect as the main purpose of the test is to assess the heart's response to physical stress, not medication effectiveness.

2. The nurse is caring for a client who has returned to the unit after undergoing a cardiac catheterization. The nurse should monitor for which common complication following this procedure?

• A. Hypertension
• B. Hypotension
• C. Hemorrhage
• D. Hyperglycemia

Correct answer: C

Rationale: Following a cardiac catheterization, a common complication to monitor for is bleeding or hemorrhage at the catheter insertion site. Hemorrhage is a significant concern due to the potential for rapid blood loss, leading to hypovolemic shock and other serious complications. Monitoring for signs of bleeding, such as swelling, hematoma, or drop in hemoglobin levels, is crucial for timely intervention. Hypertension is not a common complication post-cardiac catheterization; instead, hypotension may occur due to vasovagal response or bleeding. Hyperglycemia is not typically associated with cardiac catheterization unless the client has pre-existing diabetes or stress-induced hyperglycemia.

3. The LPN/LVN is reinforcing discharge instructions to a client who has been prescribed nitroglycerin sublingual tablets for angina. Which statement by the client indicates a need for further teaching?

• A. I will keep my nitroglycerin tablets in the original glass bottle.
• B. I will sit or lie down when I take a nitroglycerin tablet.
• C. I will take a nitroglycerin tablet every 5 minutes if chest pain persists, up to a total of 3 tablets.
• D. I can swallow the nitroglycerin tablet with a glass of water if it does not dissolve quickly.

Correct answer: D

Rationale: The correct answer is D. Nitroglycerin sublingual tablets should not be swallowed; they must dissolve under the tongue to be effective. Choice A is correct as nitroglycerin tablets should be stored in their original glass container to prevent degradation. Choice B is correct as sitting or lying down when taking a nitroglycerin tablet helps prevent dizziness or fainting due to a sudden drop in blood pressure. Choice C is correct as taking a nitroglycerin tablet every 5 minutes for a maximum of 3 tablets is the correct protocol for managing angina symptoms.

4. A client with a diagnosis of heart failure is receiving digoxin (Lanoxin) and furosemide (Lasix). The LPN/LVN should closely monitor the client for which potential complication?

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

Correct answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that promotes the loss of potassium in the urine, potentially leading to hypokalemia. Hypokalemia increases the risk of digoxin toxicity, as digoxin's effects can be potentiated in the presence of low potassium levels. Monitoring for hypokalemia is crucial to prevent adverse effects and maintain the therapeutic effectiveness of digoxin in clients with heart failure. Choices A, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hyponatremia. Instead, it commonly leads to hypokalemia due to increased potassium excretion.

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.
