1. Which lab value is critical for monitoring warfarin therapy?

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

2. A healthcare professional is preparing to administer digoxin to a client with heart failure. Which of the following laboratory values should the professional report to the provider?

Correct answer: C

Rationale: The correct answer is C: Sodium 140 mEq/L. An elevated sodium level can affect the effectiveness of digoxin therapy and may lead to toxicity. Therefore, it is crucial to report this value to the provider. Potassium, calcium, and magnesium levels are important as well, but elevated sodium can have a more direct impact on digoxin therapy in this scenario.

3. A client who is at 28 weeks of gestation is being taught by a nurse about managing heartburn. Which of the following instructions should the nurse include?

Correct answer: A

Rationale: The correct instruction for managing heartburn during pregnancy is to eat small, frequent meals. This helps prevent heartburn by reducing gastric distention. Option B, drinking a glass of milk with each meal, may exacerbate heartburn in some individuals due to its fat content. Option C, lying down after meals, can worsen heartburn as it allows stomach acid to flow back into the esophagus. Option D, drinking plenty of fluids with meals, can also contribute to heartburn by distending the stomach. Therefore, the best advice for managing heartburn during pregnancy is to eat small, frequent meals.

4. A nurse is assessing a client who is postoperative following a hip arthroplasty. Which of the following findings should the nurse report to the provider?

Correct answer: B

Rationale: Redness and warmth in the calf can indicate a blood clot, specifically deep vein thrombosis (DVT), which is a serious complication post hip arthroplasty. The warmth and redness are signs of inflammation due to the clot formation. DVT can lead to a pulmonary embolism if not addressed promptly. Monitoring for this complication is crucial in postoperative care. Elevated heart rate, oxygen saturation within normal limits, and a slightly elevated temperature are common findings postoperatively and may not be alarming in the absence of other concerning symptoms.

5. A client is receiving opioid analgesics for pain management. Which of the following assessments is the priority?

Correct answer: C

Rationale: The correct answer is C: Monitor the client's respiratory rate. When a client is receiving opioid analgesics, the priority assessment is monitoring respiratory rate. Opioids can cause respiratory depression, so it is crucial to assess the client's breathing to detect any signs of respiratory distress promptly. Checking the client's blood pressure (Choice A) and urinary output (Choice B) are important assessments too, but they are not the priority when compared to ensuring adequate respiratory function. Assessing the client's pain level (Choice D) is essential for overall care but is not the priority assessment when the client is on opioids, as respiratory status takes precedence.
