In the emergency department, which medication client requires monitoring with electrocardiogram equipment?

Monitoring with electrocardiogram (ECG) equipment is particularly important for the client receiving naproxen due to its potential cardiovascular effects. Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), can influence blood pressure and increase the risk of cardiovascular events, especially in certain populations. In the emergency department, patients taking NSAIDs like naproxen may experience changes in heart rhythm or arrhythmias, necessitating careful cardiac monitoring.

While aspirin is also an NSAID, its use in low doses is frequently associated with cardioprotective effects, which reduces the urgency for ECG monitoring. Ibuprofen and acetaminophen, on the other hand, generally have less significant cardiovascular implications and typically don't warrant the same level of monitoring in an emergency setting. Therefore, the client receiving naproxen stands out as the one who requires ECG monitoring due to the associated risks that may arise from its usage.
