A mother calls the nurse to report that at 0900 she administered an oral dose of digoxin to her 4-month-old infant, but at 0920 the baby vomited the medicine. Which instruction should the nurse provide to this mother?

Choice A: Think about reasons the episodes occur. This is not the best instruction, as it may increase the anxiety level of the client. Thinking about reasons may trigger negative thoughts, emotions, or memories that can worsen the anxiety. The nurse should teach the client to focus on coping skills rather than causes.

Choice B: Center attention on positive upbeat music. This is not the best instruction, as it may not be effective for all clients. Listening to positive upbeat music may help distract or soothe some clients, but it may also irritate or annoy others. The nurse should teach the client to choose music that matches their mood and preference.

Choice C: Practice using muscle relaxation techniques. This is the best instruction, as it can reduce the physical symptoms of anxiety. Muscle relaxation techniques involve tensing and relaxing different muscle groups in a systematic way, which can lower blood pressure, heart rate, and breathing rate. The nurse should teach the client how to perform muscle relaxation techniques and practice them regularly.

Choice D: Find outlets for more social interaction. This is not the best instruction, as it may not be feasible or helpful for all clients. Finding outlets for more social interaction may help some clients feel supported or connected, but it may also stress or overwhelm others. The nurse should teach the client to seek social support that is appropriate and comfortable for them.

Choice A: Taking metformin with the morning and evening meal is a correct statement for the nurse to include, as this can improve the absorption and effectiveness of metformin and reduce the risk of gastrointestinal side effects. Therefore, this is a correct choice.

Choice B: Using sliding scale insulin for frequent blood glucose elevations is not a correct statement for the nurse to include, as this is not recommended for clients with type 2 DM who are taking metformin. This can cause hypoglycemia and complicate the management of blood glucose levels. This is an incorrect choice.

Choice C: Recognizing signs and symptoms of hypoglycemia is a correct statement for the nurse to include, as this can help the client identify and treat low blood glucose levels, which can occur with metformin use or other factors such as exercise, fasting, or alcohol intake. Therefore, this is another correct choice.

Choice D: Reporting persistent polyuria to the health care provider is a correct statement for the nurse to include, as this can indicate poor glycemic control or a complication of DM such as diabetic ketoacidosis or nephropathy. Therefore, this is another correct choice.

Choice E: Taking an additional dose for signs of hyperglycemia is not a correct statement for the nurse to include, as this can cause overdose or toxicity of metformin, which can lead to lactic acidosis and renal failure. This is another incorrect choice.
