The nurse assesses a client who is receiving an infusion of 5% dextrose in water with 20 mEq of potassium chloride. The client has oliguria and a serum potassium level of 6.5 mEq/L. What action should the nurse implement first?
- A. Notify the healthcare provider of the laboratory results
- B. Decrease the rate of the IV infusion
- C. Stop the infusion
- D. Administer sodium polystyrene sulfonate (Kayexalate)
Correct Answer: C
Rationale: The correct action for the nurse to implement first is to stop the infusion (Choice C). Oliguria and a high serum potassium level indicate the client is at risk for hyperkalemia, which can be exacerbated by the potassium chloride infusion. Stopping the infusion is crucial to prevent further elevation of potassium levels and potential cardiac complications.
Choice A (Notify the healthcare provider) is not the first action as immediate intervention is needed to prevent harm. Choice B (Decrease the rate of the IV infusion) is not sufficient to address the immediate risk of hyperkalemia. Choice D (Administer sodium polystyrene sulfonate) is not appropriate as the first action and should only be considered after stabilizing the client's condition.

The nurse is planning care for a client receiving chemotherapy. Which intervention should the nurse include to manage the client's nausea?
- A. Administer an antiemetic before meals
- B. Provide frequent mouth care
- C. Encourage small, frequent meals
- D. Offer clear liquids
Correct Answer: A
Rationale: The correct answer is A: Administer an antiemetic before meals. Administering an antiemetic before meals helps prevent and manage nausea associated with chemotherapy by blocking receptors that trigger nausea and vomiting. This intervention targets the root cause of the symptom. Providing frequent mouth care (B) may help with taste changes but does not directly address nausea. Encouraging small, frequent meals (C) and offering clear liquids (D) may be helpful for some clients, but they do not specifically target nausea caused by chemotherapy.
A 3-year-old boy is brought to the emergency center with dysphagia, drooling, a fever of 102°F, and stridor. Which intervention should the nurse implement first?
- A. Place the child in a mist tent
- B. Obtain a sputum culture
- C. Prepare for an emergent tracheostomy
- D. Examine the child's oropharynx and report the findings to the healthcare provider
Correct Answer: A
Rationale: The correct answer is A: Place the child in a mist tent. This intervention is crucial in managing a child with croup, which presents with stridor, fever, and respiratory distress. Placing the child in a mist tent provides humidified air, which can help reduce airway inflammation and ease breathing. It is the first-line treatment for croup and should be initiated promptly to relieve the child's symptoms. Obtaining a sputum culture (B) is not necessary in this scenario as the child's presentation is consistent with croup, which is a clinical diagnosis. Preparing for an emergent tracheostomy (C) is an invasive procedure that should only be considered if other treatments fail. Examining the child's oropharynx (D) can be helpful but is not the most urgent intervention in this situation.
A male client with diabetes mellitus takes Novolin 70/30 insulin before meals and azithromycin (Zithromax) PO daily, using medication he brought from home. When the nurse delivers his breakfast tray, the client tells the nurse that he took his insulin but forgot to take his daily dose of the Zithromax an hour before breakfast as instructed. What action should the nurse implement?
- A. Offer to obtain a new breakfast tray in an hour so the client can take the Zithromax
- B. Instruct the client to eat his breakfast and take the Zithromax two hours after eating
- C. Tell the client to skip that day's dose and resume taking the Zithromax the next day
- D. Provide a PRN dose of an antacid to take with the Zithromax right after breakfast
Correct Answer: B
Rationale: The correct answer is B: Instruct the client to eat his breakfast and take the Zithromax two hours after eating. This is the correct action because azithromycin is best absorbed when taken on an empty stomach, but if the client has already eaten, it is recommended to wait at least 2 hours after a meal before taking it. This ensures optimal absorption and effectiveness of the medication.
Choice A is incorrect because it does not address the timing issue of taking azithromycin on an empty stomach. Choice C is incorrect as skipping a dose of an antibiotic can lead to treatment failure. Choice D is incorrect as antacids can interfere with the absorption of azithromycin and should not be taken together.
A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute by nasal cannula. The client develops respiratory distress and the nurse increases the oxygen to 4 liters per minute. Shortly afterward, the client becomes lethargic and confused. What action should the nurse take first?
- A. Reposition the nasal cannula
- B. Lower the oxygen rate
- C. Encourage the client to cough and deep breathe
- D. Monitor the client's oxygen saturation level
Correct Answer: B
Rationale: The correct answer is B: Lower the oxygen rate. Increasing oxygen flow too quickly can lead to oxygen toxicity in COPD patients, causing symptoms like lethargy and confusion. Lowering the oxygen rate will help alleviate the symptoms and prevent further harm. Repositioning the nasal cannula (choice A) is not the priority in this situation. Encouraging coughing and deep breathing (choice C) may not address the immediate issue of oxygen toxicity. Monitoring oxygen saturation (choice D) is important but should follow lowering the oxygen rate to address the current symptoms.
A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?
- A. It dissolves blood clots
- B. It prevents the blood from clotting
- C. It thins the blood
- D. It decreases the risk of infection
Correct Answer: B
Rationale: The correct answer is B: It prevents the blood from clotting. Warfarin works as an anticoagulant by inhibiting the production of certain clotting factors in the liver. This prevents the formation of blood clots and reduces the risk of conditions like deep vein thrombosis or stroke. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones. Choice C is misleading as it does not actually "thin" the blood but affects its ability to clot. Choice D is unrelated to the mechanism of action of warfarin.
