A nurse is reinforcing teaching about foot care with a client who has type 2 diabetes mellitus.

Which of the following statements by the client indicates an understanding of the teaching?

Delirium is a state of acute confusion and cognitive impairment that can cause disorientation and difficulty with time perception. Reminding the client of the day and time frequently helps provide orientation and reduce confusion. It can help ground the client in reality and improve their understanding of their current circumstances.

Avoiding discussing the client's fears can hinder their ability to express and address their concerns. It is important to provide a safe and supportive environment where the client can communicate their fears and feelings.

Offering the client several choices at mealtimes might be overwhelming and confusing for someone experiencing delirium. It is generally better to provide structure and simplicity in their meal options, reducing decision-making demands.

Alternating daily caregivers can disrupt continuity of care and increase the client's confusion. Consistency in the caregiving team can help establish a therapeutic relationship and familiarity, which can aid in managing delirium.

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.
