A nurse is reinforcing teaching with the parents of a child who has ADHD and is taking methylphenidate. Which of the following statements by the parents indicates that the medication is effective?

Thrombocytopenia is a condition characterized by a low platelet count, which can lead to impaired blood clotting and an increased risk of bleeding. The use of a firm-bristled toothbrush can cause trauma to the gums and oral tissues, increasing the risk of bleeding in someone with thrombocytopenia. It is recommended for individuals with thrombocytopenia to use a soft-bristled toothbrush to minimize the risk of oral bleeding.

Wearing a face mask around others, increased intake of green, leafy vegetables, and getting an adequate amount of sleep do not directly increase the client's risk for injury in the context of thrombocytopenia. These practices are generally beneficial for overall health and well-being.

Prednisone can cause blood glucose levels to increase.

The nurse should explain to the client that the reason for checking his blood glucose level is because prednisone, a medication he is receiving, can cause an increase in blood glucose levels. Prednisone is a corticosteroid medication that is commonly used in the treatment of various conditions, including COPD. It has the potential to raise blood glucose levels by promoting gluconeogenesis (the production of glucose from non-carbohydrate sources) and decreasing insulin sensitivity. Monitoring blood glucose levels is important to assess and manage any potential hyperglycaemia or changes in the client's blood sugar levels while on prednisone.

Older adults are not at increased risk for developing type 1 diabetes mellitus in (option A) is incorrect. Type 1 diabetes is an autoimmune condition that typically occurs in childhood or adolescence, and it is characterized by the destruction of insulin-producing cells in the pancreas.

Albuterol treatments, which are used to relieve bronchospasms in clients with COPD, are not known to cause blood glucose levels to decrease in (option C) is incorrect. Albuterol is a beta-2 adrenergic agonist that primarily acts on the respiratory system and does not have a direct effect on blood glucose levels.

Having COPD does not directly cause blood glucose levels to fluctuate in (option D) is incorrect. While there can be various factors that may indirectly affect blood glucose levels in individuals with COPD (e.g., medications, stress, comorbidities), the primary reason for monitoring blood glucose in this case is the use of prednisone.

In summary, the nurse should explain to the client that the blood glucose levels are being checked because prednisone, a medication he is taking for his COPD, can cause an increase in blood glucose levels. This allows for appropriate monitoring and management of any potential hyperglycemia associated with the use of prednisone.
