A nurse is teaching a client who has a new prescription for metformin extended-release tablets.
Which of the following statements by the client indicates an understanding of the teaching?
A.
“I will take the medication in the morning.”
B.
“I will expect to gain weight.”
C.
“I will take the medication on an empty stomach.”
D.
“I will avoid crushing this medication.”
The Correct Answer and Explanation is:
The correct answer is D. “I will avoid crushing this medication.”
Explanation:
Metformin extended-release (ER) tablets are designed to release the medication slowly over time, providing a steady level of the drug in the bloodstream. Here’s why each option is evaluated in this context:
A. “I will take the medication in the morning.”
While taking metformin in the morning is not incorrect, the timing of metformin ER tablets does not have to be specific to the morning. The primary consideration is to take it consistently at the same time each day, as directed by the healthcare provider. Metformin ER can be taken with the evening meal or at a time that fits into the client’s routine, making this statement less relevant in ensuring understanding of the medication’s proper use.
B. “I will expect to gain weight.”
This statement is incorrect. One of the benefits of metformin is that it is associated with weight neutrality or even weight loss, not weight gain. Metformin works by improving insulin sensitivity and decreasing hepatic glucose production, which can help with weight management. Therefore, expecting weight gain is not a typical effect of metformin.
C. “I will take the medication on an empty stomach.”
This statement is also incorrect. Metformin ER tablets should be taken with food to minimize gastrointestinal side effects such as nausea, diarrhea, and abdominal discomfort. Taking metformin with a meal helps to reduce these side effects and improves the absorption of the medication.
D. “I will avoid crushing this medication.”
This statement indicates correct understanding. Metformin ER tablets are formulated to release the medication slowly and are coated to protect the medication and ensure its gradual release. Crushing or chewing the tablets would disrupt this controlled-release mechanism, potentially leading to increased side effects or reduced efficacy. Therefore, it is important to swallow the tablets whole to maintain their intended effect.
In summary, understanding that metformin ER tablets should not be crushed or chewed reflects proper knowledge of how to administer the medication to ensure its effectiveness and to prevent potential adverse effects.
