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 a client is suspected of having a stroke, what is the nurse's priority action?

• A. Administer tissue plasminogen activator (tPA).
• B. Perform a neurological assessment.
• C. Position the client in a supine position.
• D. Check the client's blood glucose level.

Correct answer: B

Rationale: The correct answer is to perform a neurological assessment. When a stroke is suspected, the priority action is to assess the client neurologically to determine the extent of brain injury and identify any immediate risks, such as impaired airway, speech deficits, or loss of motor function. This assessment helps in early recognition of signs that are essential for timely intervention and guides further treatment, such as administering tissue plasminogen activator (tPA), if appropriate. Positioning the client in a supine position or checking the blood glucose level can be important but not the priority when a stroke is suspected.

3. The nurse is caring for a client who had a myocardial infarction 6 hours ago. The primary goal of care at this time is to

• A. Limit the effects of tissue damage
• B. Relieve pain and anxiety
• C. Prevent arrhythmias
• D. Reduce anxiety

Correct answer: A

Rationale: The correct answer is A: 'Limit the effects of tissue damage.' After a myocardial infarction, the primary goal of care is to limit the damage to the heart muscle. This includes interventions to improve blood flow, oxygenation, and prevent further complications. Choice B ('Relieve pain and anxiety') is important but secondary to addressing tissue damage. Choice C ('Prevent arrhythmias') is also crucial but falls under the broader goal of limiting tissue damage. Choice D ('Reduce anxiety') is essential for holistic care but is not the primary goal immediately after a myocardial infarction.

4. A client with a history of stroke is receiving warfarin. What is the nurse's priority assessment?

• A. Check the client's blood pressure.
• B. Assess for signs of bleeding.
• C. Assess the client's neurological status.
• D. Monitor the client's intake and output.

Correct answer: B

Rationale: The correct answer is to assess for signs of bleeding. Warfarin is an anticoagulant that increases the risk of bleeding in patients. Monitoring for signs of bleeding such as easy bruising, petechiae, blood in urine or stool, or unusual bleeding from gums is crucial. Checking the client's blood pressure (choice A) is important but not the priority in this situation. Assessing the client's neurological status (choice C) is essential in stroke patients but is not the priority related to warfarin therapy. Monitoring intake and output (choice D) is important for overall assessment but is not the priority when a client is on warfarin, as assessing for bleeding takes precedence.

5. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.
