Nursing Elites

1. 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.

2. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Hemoglobin of 10 g/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

3. The nurse notes that a client who has undergone a thoracotomy has an increase in a large amount of dark red blood in the chest tube collection chamber. What action should the nurse take?

• A. Document the findings for this procedure as expected
• B. Notify the healthcare provider immediately
• C. Check the tube for kinks or dependent loops
• D. Increase the suction to the chest drainage system

Correct answer: B

Rationale: An increase in a large amount of dark red blood in the chest tube collection chamber may indicate active bleeding. The nurse should notify the healthcare provider immediately to address the situation promptly and prevent further complications. Documenting the findings without taking immediate action could delay necessary interventions. Checking the tube for kinks or dependent loops is a good practice but not the priority when dealing with a potentially life-threatening situation like active bleeding. Increasing the suction without healthcare provider's orders can lead to complications and is not appropriate in this scenario.

4. The nurse is preparing to administer an IV dose of ciprofloxacin to a client with a urinary tract infection. Which client data requires the most immediate intervention by the nurse?

• A. Serum creatinine of 4.5 mg/dL (398 μmol/L SI)
• B. Temperature of 101.3°F
• C. Blood pressure of 140/90 mmHg
• D. Heart rate of 88 bpm

Correct answer: A

Rationale: A serum creatinine level of 4.5 mg/dL indicates severe renal impairment, which requires immediate attention before administering ciprofloxacin. Elevated serum creatinine levels suggest decreased kidney function, and giving ciprofloxacin can further harm the kidneys. Monitoring and addressing renal function are crucial to prevent worsening of renal impairment and potential drug toxicity. The temperature, blood pressure, and heart rate are important parameters to assess, but in this scenario, the priority is to address the severe renal impairment before proceeding with ciprofloxacin administration.

5. Which instruction is most important for a client who receives a new plan of care to treat osteoporosis?

• A. Start a weight-bearing exercise plan.
• B. Increase consumption of foods rich in calcium.
• C. Arrange a bone density test every year.
• D. Stay upright after taking the medication.

Correct answer: D

Rationale: The correct answer is D: 'Stay upright after taking the medication.' This instruction is crucial for clients receiving medications like bisphosphonates to prevent esophageal irritation or erosion. While weight-bearing exercises (choice A) are important for bone health, staying upright after medication intake takes precedence. Increasing calcium-rich foods (choice B) is beneficial but not the most important immediate instruction. Scheduling bone density tests (choice C) is necessary for monitoring osteoporosis but is not as critical as staying upright after medication.
