A nurse is reviewing a list of current medications for a client who is starting therapy with furosemide. Which of the following medications should the nurse identify as being contraindicated?

A. Furosemide can decrease the renal clearance of lithium, leading to increased lithium levels in the blood. This can potentiate the toxic effects of lithium, such as neurotoxicity and cardiac toxicity. Therefore, concurrent use of furosemide and lithium is generally contraindicated, and caution is advised. The nurse should identify lithium carbonate as contraindicated in this scenario. B. Albuterol is a bronchodilator commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). There are no significant contraindications between albuterol and furosemide. C. Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. There are no significant contraindications between levothyroxine and furosemide. D. Cetirizine is an antihistamine used to treat allergies and allergic reactions. There are no significant contraindications between cetirizine and furosemide. They are generally considered safe to use together.
