1. A nurse is planning care for a client who has hypernatremia. Which of the following actions should the nurse include in the plan of care?
- A. Infuse hypotonic IV fluids.
- B. Implement a fluid restriction.
- C. Increase sodium intake.
- D. Administer sodium polystyrene sulfonate.
Correct answer: A
Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.
2. A nurse discovers a small paper fire in a trash can in a client’s bathroom. The client has been taken to safety and the alarm has been activated. Which of the following actions should the nurse take?
- A. Open the windows in the client’s room to allow smoke to escape.
- B. Obtain a class C fire extinguisher to extinguish the fire.
- C. Remove all electrical equipment from the client’s room.
- D. Place wet towels along the base of the door to the client’s room.
Correct answer: B
Rationale: The correct answer is B: Obtain a class C fire extinguisher to extinguish the fire. Using a class C fire extinguisher is appropriate for electrical fires, which can include fires involving electrical equipment or appliances. In this scenario, a paper fire in a trash can in the client's bathroom could potentially involve electrical components, making a class C fire extinguisher the most suitable choice. Option A, opening the windows, may help with ventilation but does not address the fire directly. Option C, removing electrical equipment, is a precautionary measure but does not address the immediate fire hazard. Option D, placing wet towels along the base of the door, is a strategy to prevent smoke from entering the room but does not extinguish the fire.
3. A healthcare professional is reviewing the laboratory values for a client who has a positive Chvostek's sign. Which of the following laboratory findings should the healthcare professional expect?
- A. Decreased calcium
- B. Elevated potassium
- C. Increased sodium
- D. Low hemoglobin
Correct answer: A
Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.
4. A client with a history of chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client is short of breath and has a pulse oximetry reading of 88%. What action should the LPN take first?
- A. Increase the oxygen flow rate to 4 liters per minute.
- B. Reposition the client to a high Fowler's position.
- C. Notify the healthcare provider of the client's condition.
- D. Encourage the client to use pursed-lip breathing.
Correct answer: B
Rationale: Repositioning the client to a high Fowler's position should be the first action taken by the LPN. This position helps improve oxygenation by maximizing lung expansion, making it easier for the client to breathe. Increasing the oxygen flow rate without addressing positioning may not fully optimize oxygen delivery. Notifying the healthcare provider should come after immediate interventions. Encouraging pursed-lip breathing is beneficial but should follow the initial positioning to further assist the client in managing their breathing difficulty.
5. A client with moderate persistent asthma is admitted for a minor surgical procedure. On admission, the peak flow meter is measured at 480 liters/minute. Post-operatively, the client is complaining of chest tightness. The peak flow has dropped to 200 liters/minute. What should the nurse do first?
- A. Notify the healthcare provider
- B. Administer the PRN dose of Albuterol
- C. Apply oxygen at 2 liters per nasal cannula
- D. Repeat the peak flow reading in 30 minutes
Correct answer: B
Rationale: In a client with moderate persistent asthma experiencing a drop in peak flow and chest tightness post-operatively, the first action the nurse should take is to administer the PRN dose of Albuterol. Albuterol is a short-acting bronchodilator that helps relieve bronchospasm and improve breathing. Notifying the healthcare provider (choice A) can be done after initiating immediate treatment with Albuterol. Applying oxygen (choice C) may be necessary but addressing the bronchospasm with Albuterol is the priority. Repeating the peak flow reading (choice D) can be considered after administering Albuterol to assess the response to treatment.
