Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

3. A client receiving IV heparin reports tarry stools and abdominal pain. What interventions should the nurse implement?

• A. Prepare to administer warfarin.
• B. Assess the characteristics of the client's pain.
• C. Obtain recent partial thromboplastin time results.
• D. Monitor stool for the presence of blood.

Correct answer: D

Rationale: The correct intervention for the client receiving IV heparin who reports tarry stools and abdominal pain is to monitor the stool for the presence of blood. This is crucial to assess for gastrointestinal bleeding, a potential complication of heparin therapy. Assessing the characteristics of the client's pain may be helpful but is not the priority when signs of GI bleeding are present. Administering warfarin is not appropriate without a thorough assessment and confirmation of the cause of symptoms. While obtaining recent partial thromboplastin time results is important in monitoring heparin therapy, in this scenario, the immediate concern is to assess for possible GI bleeding.

4. A client with a seizure disorder is prescribed phenytoin. What is the most important teaching the nurse should provide?

• A. Take phenytoin with antacids to reduce stomach upset.
• B. Maintain a consistent dosing schedule to prevent seizures.
• C. Monitor for excessive drowsiness and dizziness.
• D. Take the medication at bedtime to reduce seizure risk.

Correct answer: B

Rationale: The most important teaching the nurse should provide to a client prescribed phenytoin is to maintain a consistent dosing schedule to prevent seizures. Phenytoin is an antiepileptic drug, and missing doses can increase the risk of seizures. Option A is incorrect because antacids can interact with phenytoin and reduce its absorption. Option C is important but not the most critical teaching as compared to maintaining a consistent dosing schedule. Option D is incorrect because the timing of phenytoin administration should be consistent rather than specifically at bedtime.

5. A client with a colostomy is being discharged. What teaching is most important for the nurse to provide?

• A. Change the ostomy bag daily to prevent skin irritation.
• B. Avoid foods that can cause gas, such as broccoli.
• C. Empty the ostomy pouch when it is one-third full.
• D. Use a skin barrier to protect the surrounding skin.

Correct answer: C

Rationale: The most important teaching for a client with a colostomy is to empty the ostomy pouch when it is one-third full. This practice helps prevent leakage and skin irritation by maintaining the proper seal of the pouching system. Changing the ostomy bag daily (Choice A) is not necessary unless it leaks or becomes loose. Avoiding gas-producing foods (Choice B) is essential for some clients but is not the most important teaching. Using a skin barrier (Choice D) is important but not as crucial as emptying the ostomy pouch at the right time to prevent complications.
