Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

2. A nurse is caring for a client who has a wound infection and is receiving gentamicin. Which of the following laboratory values should the nurse monitor to detect an adverse effect of this medication?

• A. Creatinine.
• B. Aspartate aminotransferase (AST).
• C. White blood cell count.
• D. Serum glucose.

Correct answer: A

Rationale: The correct answer is A: Creatinine. Gentamicin can cause nephrotoxicity, leading to impaired kidney function. Monitoring creatinine levels helps the nurse detect any potential kidney damage. Choice B, Aspartate aminotransferase (AST), is not typically affected by gentamicin. Choice C, White blood cell count, is not directly related to gentamicin adverse effects. Choice D, Serum glucose, is not specifically monitored for gentamicin adverse effects.

3. A nurse is assessing a client who has a chest tube and notes continuous bubbling in the water seal chamber. Which of the following actions should the nurse take?

• A. Continue to monitor the client.
• B. Clamp the chest tube.
• C. Replace the drainage system.
• D. Apply a dressing over the insertion site.

Correct answer: D

Rationale: The correct action for the nurse to take when continuous bubbling is noted in the water seal chamber of a chest tube is to apply a dressing over the insertion site. Continuous bubbling indicates an air leak, and applying a dressing helps manage this issue by providing a seal. Clamping the chest tube or replacing the drainage system is not appropriate in this situation as it can lead to complications such as tension pneumothorax or inadequate drainage of the pleural space.

4. A client has a nasogastric tube for gastric decompression. Which of the following actions should the nurse take?

• A. Check for the presence of bowel sounds every 8 hours.
• B. Flush the NG tube every 24 hours.
• C. Provide the client with sips of water every 2 hours.
• D. Keep the client's head of the bed elevated to 45 degrees.

Correct answer: D

Rationale: The correct answer is to keep the client's head of the bed elevated to 45 degrees. This position helps prevent aspiration in clients with a nasogastric tube for gastric decompression by reducing the risk of reflux and promoting proper drainage. Choice A is incorrect because checking for bowel sounds is not directly related to the care of a nasogastric tube. Choice B is incorrect as flushing the NG tube every 24 hours is not a standard nursing practice and may lead to complications. Choice C is incorrect because providing sips of water may interfere with the purpose of gastric decompression, which is to keep the stomach empty.

5. A nurse is caring for an adult client who has prescriptions for multiple medications. Which of the following is an age-related change that increases the risk for adverse effects from these medications?

• A. Rapid gastric emptying
• B. Prolonged medication half-life
• C. Increased medication elimination
• D. Decreased medication sensitivity

Correct answer: B

Rationale: The correct answer is B: Prolonged medication half-life. As clients age, their metabolism tends to slow down, leading to a prolonged half-life of medications in the body. This extended presence of drugs can increase the risk for adverse effects as the substances accumulate. Choice A, rapid gastric emptying, is not an age-related change and actually decreases the time medications spend in the stomach, potentially reducing their effectiveness. Choice C, increased medication elimination, is not an age-related change either; in fact, aging can lead to decreased renal function, affecting drug elimination. Choice D, decreased medication sensitivity, is not an age-related change that directly increases the risk for adverse effects; rather, it may lead to requiring higher doses for effectiveness but does not inherently increase the risk of adverse effects.
