A nurse is providing teaching to a client who has diabetes mellitus about the glycosylated hemoglobin blood test. Which of the following statements by the client indicates an understanding of this test?

A) Administering the medication at bedtime is not advisable because methylphenidate is a stimulant that can cause insomnia. It's typically recommended to give it in the morning or after breakfast to help manage symptoms during the day while minimizing sleep disturbances.

B) Administering the medication after breakfast is the best practice. Taking methylphenidate with food can help reduce gastrointestinal side effects and improve the medication's effectiveness throughout the school day. This timing also aligns with the medication's action profile to support focus and attention during daytime activities.

C) While monitoring sodium intake can be important for overall health, there is no specific requirement for children taking methylphenidate to avoid excess sodium. Instead, a balanced diet is generally encouraged, and any dietary changes should be discussed with a healthcare provider.

D) Foods containing tyramine are typically associated with monoamine oxidase inhibitors (MAOIs) and are not specifically a concern with methylphenidate. Therefore, advising avoidance of tyramine-rich foods is not relevant in this context, and the focus should be on proper medication management and monitoring for side effects.

A) Edema: While edema can occur in some patients, it is not a common or serious side effect of simvastatin. Clients should monitor for any unusual swelling, but it is not the primary concern associated with this medication.

B) Weight loss: Weight loss is not typically associated with simvastatin use. Clients should be aware of their weight but reporting weight loss alone is not usually necessary unless it is significant or accompanied by other concerning symptoms.

C) Muscle weakness: Simvastatin can lead to muscle-related side effects, including myopathy and rhabdomyolysis, which can present as muscle weakness. It is critical for clients to monitor for any unexplained muscle pain, tenderness, or weakness and report these symptoms to the provider, as early intervention can prevent serious complications.

D) Fever: Fever is not a typical side effect of simvastatin. While clients should report any signs of infection or unusual symptoms, fever alone is not specifically linked to the use of this medication and does not warrant immediate concern related to simvastatin therapy.
