A client with acute renal injury (AKI) weighs 110.3 pounds (50 kg) and has a potassium level of 6.7 mEq/L (6.7 mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?

Reference Range:
Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)]

Choice A reason: An abdominal catheter is used for peritoneal dialysis, not hemodialysis. Hemodialysis requires access to a large blood vessel, usually in the arm or leg.

Choice B reason: Routine medications may need to be adjusted or avoided before or after hemodialysis, depending on their effects on blood pressure, fluid balance, and electrolytes.

Choice C reason: Insulin dosage may need to be reduced during hemodialysis because insulin is removed by the dialyzer and blood glucose levels may drop. This is the correct statement to include in client education.

Choice D reason: Potassium-rich foods should be limited in the diet of clients with chronic kidney disease and hemodialysis, because potassium can build up in the blood and cause cardiac arrhythmias.

Choice A reason: Obtaining a soft diet for the client is not the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. A soft diet can help reduce the irritation and discomfort of the oral mucosa, but it does not address the underlying cause of the inflammation and infection. The nurse should first assess the client's oral hygiene and provide appropriate interventions to prevent further complications.

Choice B reason: Encouraging frequent mouth care is the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. Frequent mouth care can help prevent or reduce the severity of mucositis by removing plaque, bacteria, and debris from the oral cavity, and by moisturizing and soothing the oral tissues. The nurse should instruct the client to use a soft toothbrush, a mild toothpaste, and a saline or bicarbonate rinse at least four times a day, and to avoid alcohol, tobacco, spicy, acidic, or hot foods and beverages.

Choice C reason: Cleansing the tongue and mouth with swabs is not the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. Swabs can be abrasive and damaging to the oral mucosa, especially if they are dry or contain alcohol or hydrogen peroxide. Swabs can also increase the risk of bleeding, infection, and ulceration of the oral tissues. The nurse should use a soft toothbrush or a gentle sponge to clean the tongue and mouth.

Choice D reason: Administering a topical analgesic per protocol is not the best initial nursing action for a client with chemotherapy-induced mucositis who is describing soreness of the tongue and oral issues. A topical analgesic can provide temporary relief of pain and discomfort, but it does not address the underlying cause of the inflammation and infection. The nurse should first assess the client's oral hygiene and provide appropriate interventions to prevent further complications. The nurse should also monitor the client's response to the analgesic and report any adverse effects or inadequate pain control.
