Nursing Elites

1. The client with heart failure is prescribed furosemide (Lasix). Which electrolyte imbalance is the nurse most likely to monitor for?

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

Correct answer: C

Rationale: The correct answer is C: Hypokalemia. Furosemide, a loop diuretic, commonly causes potassium loss, leading to hypokalemia. The nurse should closely monitor for decreased potassium levels in a client receiving furosemide to prevent complications such as cardiac arrhythmias or muscle weakness. Hyperkalemia (Choice A) is not typically associated with furosemide use. Hypernatremia (Choice B) refers to high sodium levels and is not the primary concern with furosemide. Hyponatremia (Choice D) is low sodium levels, which can occur but is less common than hypokalemia in clients taking furosemide.

2. A client with a history of angina pectoris complains of substernal chest pain. The nurse checks the client's blood pressure and administers nitroglycerin 0.4 mg sublingually. Five minutes later, the client is still experiencing chest pain. If the blood pressure is still stable, what should the nurse do next?

• A. Administer another nitroglycerin tablet.
• B. Apply 1 to 3 L/minute of oxygen via nasal cannula.
• C. Call for a 12-lead electrocardiogram (ECG) to be performed.
• D. Wait an additional 5 minutes, then give a second nitroglycerin tablet.

Correct answer: A

Rationale: When a client with angina pectoris continues to experience chest pain despite initial nitroglycerin administration and stable blood pressure, the appropriate next step is to administer another nitroglycerin tablet. This helps to further dilate coronary arteries, improving blood flow to the heart muscle and relieving chest pain. Applying oxygen via nasal cannula (Choice B) may be necessary if the client displays signs of respiratory distress or hypoxemia, but in this case, the priority is addressing the unresolved chest pain. Calling for a 12-lead electrocardiogram (ECG) (Choice C) is important to assess for any changes in the client's cardiac status, but administering another nitroglycerin tablet takes precedence in managing the ongoing chest pain. Waiting an additional 5 minutes before giving a second nitroglycerin tablet (Choice D) may delay symptom relief and potentially worsen the client's condition if the chest pain persists.

3. A client with schizophrenia taking clozapine is being assessed by a nurse. Which of the following findings is the priority for the nurse to report to the provider?

• A. Elevated blood pressure
• B. Fever
• C. Weight gain
• D. Dry mouth

Correct answer: B

Rationale: The priority finding for the nurse to report to the provider is B: Fever. Fever can be an indication of agranulocytosis, a potentially life-threatening condition associated with clozapine. Agranulocytosis is characterized by a significant decrease in white blood cells, making the client susceptible to severe infections. Prompt reporting of fever is crucial to prevent serious complications. Elevated blood pressure (Choice A), weight gain (Choice C), and dry mouth (Choice D) are important to monitor but are not as immediately concerning as fever, which could indicate a severe adverse reaction requiring urgent medical attention.

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 healthcare professional is assisting in the care of a client diagnosed with heart failure. The client is receiving furosemide (Lasix). Which laboratory value should the healthcare professional monitor most closely?

• A. Serum calcium
• B. Serum potassium
• C. Serum sodium
• D. Serum glucose

Correct answer: B

Rationale: Furosemide is a loop diuretic that can lead to significant potassium loss, making it crucial to monitor the client's serum potassium levels. Hypokalemia (low potassium levels) can result from furosemide use, potentially leading to adverse effects such as cardiac dysrhythmias. Therefore, close monitoring of serum potassium levels is essential to prevent complications in clients receiving furosemide. Monitoring serum calcium, sodium, or glucose levels is not the priority when administering furosemide.
