A nurse is reviewing the medical record of a client who reports his urine is red-orange. The nurse should identify that which of the following medications can cause this adverse effect?

Choice A reason: Filling the pad with sterile water is not necessary, as tap water can be used for an aquathermia pad without increasing the risk of infection or contamination.

Choice B reason: Using safety pins to secure the pad in place is not appropriate, as they can puncture or damage the pad and cause leakage or electric shock.

Choice C reason: Applying the pad for 45 min at a time is not recommended, as it can cause skin burns or tissue damage due to prolonged exposure to heat. The nurse should apply the pad for no more than 20 min at a time and check the skin frequently for signs of redness or blistering.

Choice D reason: Covering the pad prior to use is an important action, as it can prevent direct contact between the pad and the skin and reduce the risk of burns or irritation. The nurse should use a towel or a cloth to cover the pad before applying it to the affected area.

Choice A: This is incorrect because weight loss is not the highest priority finding for the nurse to report to the provider. Weight loss can be a common symptom of leukemia due to decreased appetite, increased metabolism, or malabsorption.

Choice B: This is incorrect because fatigue is not the highest priority finding for the nurse to report to the provider. Fatigue can be a common symptom of leukemia due to anemia, infection, or poor nutrition.

Choice C: This is incorrect because dysuria is not the highest priority finding for the nurse to report to the provider. Dysuria can indicate a urinary tract infection, which can be treated with antibiotics and fluids.

Choice D: This is correct because elevated temperature is the highest priority finding for the nurse to report to the provider. Elevated temperature can indicate a serious infection, which can be life-threatening for a client who has leukemia and a compromised immune system.
