Nursing Elites

1. The nurse is caring for a client with a history of atrial fibrillation who is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Prothrombin time (PT)
• B. Hemoglobin level
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps determine if the client's blood is clotting appropriately. While prothrombin time (PT) is related to warfarin therapy, the INR is a more precise measure. Hemoglobin level and serum sodium level are not directly related to monitoring warfarin therapy.

2. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which intervention should the nurse implement first?

• A. Obtain a blood glucose level.
• B. Administer an anticoagulant as prescribed.
• C. Perform a neurological assessment.
• D. Administer aspirin as prescribed.

Correct answer: C

Rationale: Performing a neurological assessment is the priority in this situation as it helps in evaluating the cause of the new onset of confusion in a client with atrial fibrillation. This assessment will provide crucial information about the client's neurological status, which can guide further interventions. Obtaining a blood glucose level (Choice A) is important but should not be the first step when dealing with a new onset of confusion. Administering an anticoagulant (Choice B) or aspirin (Choice D) may be necessary depending on the underlying cause, but assessing the neurological status comes first to determine the appropriate course of action.

3. A male client notifies the nurse that he feels short of breath and has chest pressure radiating down his left arm. A STAT 12-lead electrocardiogram (ECG) is obtained and shows ST segment elevation in leads II, III, aVF, and V4R. The nurse collects blood samples and gives a normal saline bolus. What action is most important for the nurse to implement?

• A. Obtain the results for STAT serum cardiac biomarkers.
• B. Assess for contraindications for thrombolytic therapy.
• C. Measure ST-segment height and waveform changes.
• D. Transfer for percutaneous coronary intervention (PCI).

Correct answer: B

Rationale: Assessing for contraindications for thrombolytic therapy is crucial as it determines whether the client is a candidate for reperfusion therapy. In this scenario, the client is presenting with symptoms and ECG changes consistent with an acute myocardial infarction (MI). Thrombolytic therapy aims at restoring blood flow to the heart muscle, reducing the size of the infarct. However, it is essential to assess for contraindications such as recent surgery, active bleeding, or a history of stroke to avoid potential complications. Obtaining serum cardiac biomarkers or measuring ST-segment changes are important steps in the diagnosis of MI but are not as time-sensitive as assessing for contraindications to thrombolytic therapy. Transfer for percutaneous coronary intervention (PCI) is a definitive treatment for MI, but assessing for thrombolytic therapy eligibility takes precedence in this acute situation.

4. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which assessment finding requires immediate intervention?

• A. Elevated blood pressure
• B. Increased fatigue
• C. Headache
• D. Elevated hemoglobin

Correct answer: A

Rationale: The correct answer is A: Elevated blood pressure. In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure requires immediate intervention. This finding is concerning as it may indicate worsening hypertension, which can lead to further complications. Increased fatigue (choice B) is common in CKD but may not require immediate intervention unless severe. Headache (choice C) can be a symptom to monitor but does not pose an immediate threat like elevated blood pressure. Elevated hemoglobin (choice D) is actually a desired outcome of erythropoietin therapy and does not require immediate intervention.

5. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which laboratory value is most concerning?

• A. Serum potassium of 3.0 mEq/L
• B. Serum glucose of 200 mg/dl
• C. Serum pH of 7.30
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: In a client with Hyperosmolar Hyperglycemic State (HHS), a serum pH of 7.30 is the most concerning value as it indicates acidosis, a life-threatening condition that requires immediate intervention. Choices A, B, and D are not the most concerning in this scenario. A low serum potassium level (Choice A) may be expected due to cellular shift in hyperglycemia, a serum glucose level of 200 mg/dl (Choice B) is not as concerning compared to the extremely high initial glucose level, and a serum sodium level of 135 mEq/L (Choice D) is within the normal range and not the immediate priority.
