A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
- A. Serum sodium level.
- B. Serum potassium level.
- C. Serum calcium level.
- D. Serum glucose level.
Correct Answer: B
Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

A client with cirrhosis and ascites is receiving furosemide 40 mg BID. The pharmacy provides 20 mg tablets. How many tablets should the client receive each day? [Enter numeric value only]
- A. 4 tablets
- B. 3 tablets
- C. 2 tablets
- D. 1 tablet
Correct Answer: A
Rationale: To calculate the total daily dose of furosemide needed, 40 mg BID (twice a day) is 80 mg/day. Since each tablet is 20 mg, the client should receive a total of 4 tablets per day (80 mg · 20 mg per tablet = 4 tablets). Therefore, the correct answer is 4 tablets. Choice B (3 tablets) is incorrect because it does not provide the correct total daily dose. Choice C (2 tablets) is incorrect as it would not meet the required dose of 80 mg/day. Choice D (1 tablet) is incorrect as it would be insufficient to achieve the prescribed daily dose.
In a client with moderate, persistent, chronic neuropathic pain due to diabetic neuropathy who takes gabapentin (Neurontin) and ibuprofen (Motrin, Advil) daily, if Step 2 of the World Health Organization (WHO) pain relief ladder is prescribed, which drug protocol should be implemented?
- A. Continue gabapentin.
- B. Discontinue ibuprofen.
- C. Add aspirin to the protocol.
- D. Add oral methadone to the protocol.
Correct Answer: A
Rationale: In the presence of moderate, persistent, chronic neuropathic pain, the WHO pain relief ladder recommends continuing gabapentin, as it is effective for managing both anxiety and pain. Ibuprofen, a nonsteroidal anti-inflammatory drug, is not the mainstay for neuropathic pain relief according to the ladder and can be discontinued if needed. Aspirin is not typically added to the protocol for neuropathic pain management at this step. Methadone is reserved for severe pain and is not the standard choice at Step 2 of the WHO pain relief ladder for neuropathic pain.
The census on the unit is 90 percent, and there are no private rooms available. An elderly client with influenza is admitted. Which of the following rooms would it be appropriate to assign this client?
- A. A double room with a client admitted for impetigo.
- B. A double room with another client with the same diagnosis.
- C. A four-bed room with three clients who have had orthopedic surgery.
- D. A double room with an elderly client with a diagnosis of chickenpox.
Correct Answer: B
Rationale: When a private room is not an option, the best choice is to assign the elderly client with influenza to a double room with another client diagnosed with the same condition. This is ideal as droplet precautions would likely already be in place for the other client, reducing the risk of spreading the infection to other clients in the unit. Choice A is not appropriate as impetigo does not require the same precautions as influenza. Choice C is not ideal as orthopedic surgery does not involve respiratory precautions. Choice D is incorrect because chickenpox requires airborne precautions, which could pose a risk to the elderly client with influenza.
The nurse determines that a postoperative client's respiratory rate has increased from 18 to 24 breaths/min. Based on this assessment finding, which intervention is most important for the nurse to implement?
- A. Encourage the client to increase ambulation in the room.
- B. Offer the client a high-carbohydrate snack for energy.
- C. Force fluids to thin the client's pulmonary secretions.
- D. Determine if pain is causing the client's tachypnea.
Correct Answer: D
Rationale: An increased respiratory rate can be a sign of various issues postoperatively, including pain. Assessing and managing pain is crucial as it can lead to tachypnea. Pain, anxiety, and fluid accumulation in the lungs can all contribute to an increased respiratory rate. Therefore, determining if pain is causing the tachypnea is the most important intervention to address the underlying cause. Encouraging ambulation, offering snacks, or forcing fluids are not the priority in this situation as pain assessment takes precedence in managing the increased respiratory rate.
The nurse plans to assist a male client out of bed for the first time since his surgery yesterday. His wife objects and tells the nurse to get out of the room because her husband is too ill to get out of bed. What should the nurse do first?
- A. Administer nasal oxygen at a rate of 5 L/min
- B. Help the client to lie back down in the bed
- C. Quickly pivot the client to the chair and elevate the legs
- D. Check the client's blood pressure and pulse
Correct Answer: D
Rationale: Before assisting the client out of bed, the nurse should first assess the client's blood pressure and pulse. This assessment is crucial to determine the client's physiological stability and readiness for ambulation. It ensures the client's safety during the transfer and helps prevent any potential complications that may arise from getting out of bed. Administering oxygen, lying the client back down, or quickly moving the client to a chair without assessing vital signs can compromise the client's safety and may lead to adverse outcomes.
