A client who is taking furosemide reports experiencing leg cramps, a cough, feeling tired, and palpitations. Which action should the nurse take first?

A) Place on cardiac monitoring: Given the symptoms of leg cramps, cough, fatigue, and palpitations, the client may be experiencing electrolyte imbalances, particularly hypokalemia, which is a common side effect of furosemide. Palpitations can indicate serious cardiac issues, so placing the client on cardiac monitoring is the most urgent action to ensure their safety and allow for immediate intervention if necessary. B) Monitor intake and output: While monitoring intake and output is important for clients on furosemide to assess fluid balance and kidney function, it is not the immediate priority in this scenario. The presence of palpitations and other symptoms suggests a more acute condition that requires urgent assessment and intervention. C) Raise the head of the bed: This action may provide comfort if the client is experiencing respiratory distress from the cough. However, it does not directly address the potential cardiac implications of the reported symptoms and is not the most critical step in this situation. D) Apply warm compresses to legs: While warm compresses may help alleviate leg cramps, this intervention is not the priority given the potentially serious symptoms the client is experiencing. Addressing the possibility of cardiac complications takes precedence over symptomatic relief for leg cramps.
