1. A client with hyperaldosteronism is at risk for which of the following electrolyte imbalances?
- A. Hyperkalemia
- B. Hyponatremia
- C. Hypokalemia
- D. Hypercalcemia
Correct answer: C
Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.
2. A client with heart failure receiving furosemide develops muscle weakness. What is the nurse's priority action?
- A. Administer potassium supplements as prescribed.
- B. Monitor the client’s potassium levels.
- C. Instruct the client to increase their salt intake.
- D. Discontinue the furosemide.
Correct answer: B
Rationale: Muscle weakness in a client receiving furosemide (a diuretic) is often a sign of hypokalemia, as furosemide increases potassium loss. Monitoring potassium levels is essential to identify and address any imbalances and prevent complications such as arrhythmias. Administering potassium supplements without monitoring the levels can lead to hyperkalemia, which has its own set of serious complications. Instructing the client to increase salt intake is not appropriate in this situation as it does not address the underlying electrolyte imbalance. Discontinuing furosemide abruptly can worsen heart failure symptoms; therefore, monitoring potassium levels and adjusting the treatment accordingly is the most appropriate action.
3. A child is brought to the emergency department after ingesting an unknown quantity of acetaminophen. What is the most important action for the nurse to take?
- A. Assess the child's level of consciousness.
- B. Prepare to administer activated charcoal.
- C. Notify the poison control center.
- D. Obtain an order for serum acetaminophen levels.
Correct answer: D
Rationale: Obtaining serum acetaminophen levels is critical in determining the level of toxicity and guiding treatment. It helps to assess the risk of hepatotoxicity and determine the need for antidotal therapy with N-acetylcysteine. Assessing the child's level of consciousness (Choice A) is important but obtaining serum acetaminophen levels takes precedence as it directly guides the specific treatment required. Activated charcoal (Choice B) is not routinely used in acetaminophen poisoning. While notifying the poison control center (Choice C) is important, obtaining serum acetaminophen levels should be the immediate action to assess the child's condition and guide treatment.
4. The nurse is caring for a client who requires a mechanical ventilator for breathing. The high-pressure alarm goes off on the ventilator. What is the first action the nurse should perform?
- A. Disconnect the client from the ventilator and use a manual resuscitation bag
- B. Perform a quick assessment of the client's condition
- C. Call the respiratory therapist for help
- D. Press the alarm reset button on the ventilator
Correct answer: B
Rationale: The correct answer is to perform a quick assessment of the client's condition when the high-pressure alarm goes off on the ventilator. This assessment is crucial to determine the cause of the alarm and the client's current status. Option A is incorrect because disconnecting the client from the ventilator without assessing the situation can be harmful. Option C is incorrect as the nurse should first assess the client before seeking additional help. Option D is incorrect because resetting the alarm without understanding the underlying issue may lead to potential risks to the client.
5. The nurse is assessing a 1-year-old child with bronchiolitis caused by respiratory syncytial virus (RSV). Which assessment finding requires immediate intervention?
- A. Wheezing heard on expiration
- B. Oxygen saturation of 90%
- C. Respiratory rate of 40 breaths per minute
- D. Nasal flaring with sternal retractions
Correct answer: D
Rationale: Nasal flaring with sternal retractions indicates severe respiratory distress in a 1-year-old with bronchiolitis, requiring immediate intervention. Nasal flaring and sternal retractions are signs of increased work of breathing and decreased air movement, indicating the child is struggling to breathe. Wheezing on expiration (Choice A) is common in bronchiolitis but may not require immediate intervention. An oxygen saturation of 90% (Choice B) is low but may not be the most critical finding in this case. A respiratory rate of 40 breaths per minute (Choice C) is elevated but alone may not indicate the need for immediate intervention as much as nasal flaring and sternal retractions.
