The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?
- A. Phenytoin level
- B. Sodium level
- C. Hemoglobin level
- D. White blood cell count
Correct Answer: A
Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.

A client with a diagnosis of anemia is being discharged with a prescription for ferrous sulfate. What should the nurse include in the teaching plan?
- A. Take the medication with milk to enhance absorption
- B. Expect stools to be dark in color
- C. Take the medication before bedtime
- D. Avoid foods high in vitamin C
Correct Answer: B
Rationale: The correct answer is B: 'Expect stools to be dark in color.' Dark stools are a common side effect of iron supplementation due to the unabsorbed iron, and this is not a cause for concern. Choice A is incorrect because taking iron with milk can decrease its absorption due to calcium binding. Choice C is incorrect as there are no specific recommendations to take ferrous sulfate before bedtime. Choice D is also incorrect as vitamin C actually enhances iron absorption and should not be avoided.
The nurse is caring for a client with an intravenous infusion of normal saline. The client reports pain and swelling at the IV site. What is the nurse's priority action?
- A. Slow the rate of infusion
- B. Apply a warm compress to the site
- C. Discontinue the IV infusion
- D. Elevate the affected arm
Correct Answer: C
Rationale: The correct answer is to discontinue the IV infusion (Choice C). Pain and swelling at the IV site can indicate infiltration or phlebitis, which are serious complications that require immediate action. Slowing the rate of infusion (Choice A) may not address the underlying issue and can potentially worsen the condition. Applying a warm compress (Choice B) may provide temporary relief but does not address the need to discontinue the infusion. Elevating the affected arm (Choice D) is not the priority in this situation; discontinuing the infusion takes precedence to prevent further harm.
The nurse is assessing a client who has been receiving total parenteral nutrition (TPN) for several days. Which complication should the nurse monitor for?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Hyponatremia
- D. Hypokalemia
Correct Answer: B
Rationale: The correct answer is B: Hypoglycemia. When a client is receiving total parenteral nutrition (TPN) with a high glucose content, the risk of hypoglycemia is significant due to sudden increases in insulin release in response to the glucose load. The nurse should monitor for signs and symptoms of hypoglycemia such as shakiness, sweating, palpitations, and confusion. Hyperglycemia (choice A) is not typically a complication of TPN as the high glucose content is more likely to cause hypoglycemia. Hyponatremia (choice C) and hypokalemia (choice D) are electrolyte imbalances that can occur in clients receiving TPN, but hypoglycemia is the more common and immediate concern that the nurse should monitor for.
While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?
- A. Endotracheal cuff pressure greater than 25 cm H2O.
- B. Decreased lung compliance during ventilation.
- C. Bilateral crackles with increased secretions.
- D. Restless client who is biting the endotracheal tube.
Correct Answer: D
Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.
The nurse is caring for a client with an indwelling urinary catheter. What is the most important action to prevent catheter-associated urinary tract infections (CAUTI)?
- A. Perform hand hygiene before and after handling the catheter
- B. Change the catheter every 72 hours
- C. Apply antibiotic ointment at the insertion site
- D. Irrigate the catheter daily
Correct Answer: A
Rationale: Performing hand hygiene before and after handling the catheter is crucial in preventing catheter-associated urinary tract infections (CAUTI). This practice helps minimize the risk of introducing harmful microorganisms into the urinary tract. Changing the catheter every 72 hours is not recommended unless clinically indicated as it can increase the risk of infection. Applying antibiotic ointment at the insertion site is not a standard practice and may contribute to antibiotic resistance. Irrigating the catheter daily is unnecessary and can introduce pathogens into the urinary tract, increasing the risk of infection.
