What potential adverse effect should a client on metaproterenol report to their healthcare provider?

When a client is on metaproterenol, which is a bronchodilator used primarily for the treatment of asthma and other respiratory conditions, it is important for them to be aware of the potential cardiovascular effects associated with the medication. One of the notable side effects of metaproterenol is the risk of experiencing an irregular heartbeat, or arrhythmia. This can occur due to the drug's stimulant effects on the heart and its ability to stimulate beta-adrenergic receptors.

Clients should be advised to monitor their heart rate and rhythm, and report any occurrences of palpitations, fast or pounding heartbeats, or any changes that feel abnormal. Identifying and addressing these cardiovascular concerns early is crucial for the safety and well-being of the patient.

While other options like constipation, pedal edema, and decreased pulse rate may be noteworthy in different contexts or with other medications, they are not typical concerns with metaproterenol. Specifically, metaproterenol is more likely to cause increased heart rate rather than decreased, making the recognition of an irregular heartbeat a vital piece of information for patients using this medication.
