1. During an assessment, a client taking valproic acid exhibits elevated liver enzymes. What finding should the nurse report to the provider?
- A. Elevated liver enzymes
- B. Weight loss
- C. Dry mouth
- D. Increased appetite
Correct answer: A
Rationale: Elevated liver enzymes are a critical finding that the nurse should report to the provider when assessing a client taking valproic acid. It can be indicative of hepatotoxicity, a severe side effect associated with valproic acid use. Timely reporting and intervention are essential to prevent further complications and ensure the client's safety and well-being. Choices B, C, and D are not directly related to valproic acid use or the manifestation of hepatotoxicity. Weight loss, dry mouth, and increased appetite are not typically associated with elevated liver enzymes in the context of valproic acid administration.
2. A healthcare professional is assessing a client who has a new prescription for enalapril. Which of the following findings should the professional report to the provider?
- A. Frequent urination
- B. Dry cough
- C. Tremors
- D. Dizziness
Correct answer: B
Rationale: The correct answer is B: Dry cough. A dry cough is a common side effect of enalapril that can indicate the development of angioedema or potentially life-threatening angioedema. An onset of dry cough should be reported to the provider promptly as it may require discontinuation of the medication to prevent further complications. Frequent urination, tremors, and dizziness are not typically associated with enalapril use and are less likely to be of immediate concern compared to a dry cough in this context.
3. 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.
4. 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.
5. 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.
