Nursing Elites

1. In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?

• A. Serum potassium of 4.0 mEq/L
• B. Blood glucose of 200 mg/dl
• C. Serum creatinine of 1.5 mg/dl
• D. Serum potassium of 3.2 mEq/L

Correct answer: D

Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.

2. A client with rheumatoid arthritis is scheduled to receive a dose of methotrexate. Which laboratory result is most important for the nurse to review before administering the medication?

• A. White blood cell count
• B. Liver function tests
• C. Kidney function tests
• D. Complete blood count

Correct answer: B

Rationale: The correct answer is B: Liver function tests. Before administering methotrexate, it is crucial to review liver function tests due to the medication's potential hepatotoxic effects. Methotrexate can cause liver damage, so monitoring liver function is essential to prevent any serious complications. While white blood cell count, kidney function tests, and complete blood count are important parameters to monitor in certain situations, they are not the most critical before administering methotrexate.

3. A client with a history of chronic kidney disease is scheduled for a renal biopsy. Which laboratory value should the nurse report to the healthcare provider before the procedure?

• A. Serum creatinine of 1.8 mg/dl
• B. Prothrombin time of 18 seconds
• C. Hemoglobin of 9 g/dl
• D. Platelet count of 90,000/mm3

Correct answer: D

Rationale: A platelet count of 90,000/mm3 is low and concerning for a client scheduled for a renal biopsy, as it increases the risk of bleeding. Thrombocytopenia, indicated by a low platelet count, can lead to impaired blood clotting, posing a significant risk of bleeding during or after the biopsy procedure. Elevated serum creatinine levels may be expected in chronic kidney disease but are not directly related to bleeding risk during a renal biopsy. Prothrombin time and hemoglobin levels are not as directly relevant to the bleeding risk associated with a renal biopsy as platelet count.

4. The nurse is preparing a community education program on osteoporosis. Which instruction is helpful in preventing bone loss and promoting bone formation?

• A. Recommend weight-bearing physical activity.
• B. Encourage a diet high in dairy products.
• C. Suggest vitamin D supplementation.
• D. Advise avoiding caffeine and alcohol.

Correct answer: A

Rationale: The correct answer is A: Recommend weight-bearing physical activity. Weight-bearing exercises are effective in maintaining bone density and preventing osteoporosis by promoting bone formation. Encouraging a diet high in dairy products (choice B) can provide calcium, but it's not as directly related to bone formation as physical activity. While vitamin D supplementation (choice C) is important for calcium absorption and bone health, it is not directly involved in promoting bone formation. Advising to avoid caffeine and alcohol (choice D) can be beneficial for bone health, but it is not as directly related to promoting bone formation as weight-bearing physical activity.

5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning to the nurse?

• A. Barrel-shaped chest
• B. Use of accessory muscles
• C. Oxygen saturation of 85%
• D. Respiratory rate of 28 breaths per minute

Correct answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.
