Nursing Elites

1. A client with rheumatoid arthritis is prescribed methotrexate. Which assessment finding requires immediate intervention?

• A. Fever of 100.4°F
• B. Positive Chvostek's sign
• C. Increased joint pain
• D. Swelling in the joints

Correct answer: B

Rationale: A positive Chvostek's sign indicates hypocalcemia, which requires immediate intervention as it can lead to life-threatening complications. Fever, increased joint pain, and swelling in the joints are common symptoms in clients with rheumatoid arthritis but do not require immediate intervention like addressing hypocalcemia.

2. A client with a history of atrial fibrillation 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 correct answer is C, International Normalized Ratio (INR). 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 ensure that the client is within the therapeutic range for anticoagulation, reducing the risk of bleeding or clotting complications. Prothrombin time (A) is used to calculate the INR and monitor the effectiveness of warfarin therapy. Hemoglobin level (B) is important but not the primary lab value to monitor when a client is on warfarin. Serum sodium level (D) is not directly related to monitoring warfarin therapy.

3. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value requires immediate intervention?

• A. Serum potassium of 6.5 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 2.0 mg/dL
• D. Blood glucose of 150 mg/dL

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is most concerning in a client with CKD as it indicates severe hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias. Serum sodium levels within the normal range (135 mEq/L) are not immediately concerning. Serum creatinine of 2.0 mg/dL may indicate impaired kidney function but does not require immediate intervention for hyperkalemia. Blood glucose of 150 mg/dL is within normal limits and does not directly correlate with hyperkalemia in this scenario.

4. Progressive kyphoscoliosis leading to respiratory distress is evident in a client with muscular dystrophy. Which finding warrants immediate intervention by the nurse?

• A. Extremity muscle weakness.
• B. Bilateral eyelid drooping.
• C. Inability to swallow pills.
• D. Evidence of hypoventilation.

Correct answer: D

Rationale: The correct answer is D: Evidence of hypoventilation. In a client with muscular dystrophy and progressive kyphoscoliosis, hypoventilation indicates respiratory muscle weakness and can lead to life-threatening respiratory distress. Immediate intervention is crucial to prevent complications. Choices A, B, and C are incorrect because while extremity muscle weakness, bilateral eyelid drooping, and inability to swallow pills are concerning symptoms in muscular dystrophy, evidence of hypoventilation poses a more immediate threat to the client's respiratory status.

5. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
