Nursing Elites

1. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum calcium level

Correct answer: A

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.

2. An adolescent's mother calls the clinic because the teen is having recurrent vomiting and has been combative in the last 2 days. The mother states that the teen takes vitamins, calcium, and magnesium supplements along with aspirin. Which nursing intervention has the highest priority?

• A. Advise the mother to withhold all medications by mouth.
• B. Instruct the mother to take the teen to the emergency room.
• C. Recommend that the teen withhold food and fluids for 2 hours.
• D. Suggest that the adolescent breathe slowly and deeply.

Correct answer: B

Rationale: In this scenario, the highest priority nursing intervention is to instruct the mother to take the teen to the emergency room. The symptoms of recurrent vomiting, combative behavior, and the medications (vitamins, calcium, magnesium supplements, and aspirin) taken by the teen suggest a possible overdose or serious adverse reaction. Therefore, immediate medical evaluation is crucial to assess and manage any potential toxicity or adverse effects. Advising to withhold all medications by mouth (Choice A) may delay necessary treatment. Recommending withholding food and fluids for 2 hours (Choice C) may not address the underlying cause of the symptoms. Suggesting slow and deep breathing (Choice D) is not appropriate in this urgent situation requiring immediate medical attention.

3. 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.

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 chronic heart failure is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.5 mg/dl
• D. Blood glucose of 200 mg/dl

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.
