Question

A nurse is reinforcing discharge teaching with a client who has type 2 diabetes mellitus and a new prescription for metformin. The nurse should instruct the client to monitor for which of the following manifestations as adverse effects of this medication? (Select all that apply)

A. Muscle pain
B. Fatigue
C. Weight gain
D. Constipation
E. Metallic taste

Answer 1

Clients on metformin should be aware of potential adverse effects such as muscle pain, fatigue, a metallic taste, and constipation. Muscle pain and fatigue can be signs of lactic acidosis. Weight gain is not typically associated with metformin use.

Step-by-step explanation:

A nurse instructing a client with type 2 diabetes mellitus who has been prescribed metformin should advise them to monitor for several potential adverse effects. Adverse effects that could be experienced include muscle pain, fatigue, an unusual metallic taste, and constipation. Notably, weight gain is not typically associated with metformin; in fact, it often promotes weight loss or has a neutral effect on weight.

Muscle pain and fatigue could be signs of a rare but serious complication called lactic acidosis. Patients on metformin are instructed to report these symptoms to their healthcare provider immediately. Moreover, the metallic taste is a less severe side effect that some patients report but usually does not require medical attention unless it persists or is bothersome. Constipation, while less common, may also occur and patients can often manage this through dietary changes.
