A nurse is assisting with a community health presentation about home safety precautions when there is an outdoor chemical disaster nearby. Which of the following instructions should the nurse include?

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.

Informed consent is a legal and ethical requirement for certain medical procedures. It involves providing the client with clear and comprehensive information about the procedure, including its risks, benefits, alternatives, and expected outcomes. The client must understand the information provided and voluntarily give their consent before the procedure can be performed.

Placement of a central venous catheter is an invasive procedure that carries risks and potential complications, making it necessary to obtain informed consent from the client.

Wound irrigation with an antibiotic solution is a standard nursing intervention for wound care and does not usually involve invasive procedures. Informed consent is not typically required for this procedure.

The administration of an iron injection using the Z-track technique is a standard nursing procedure. While it involves an injection, it is not typically considered an invasive procedure that would require informed consent.

Insertion of a nasogastric tube is a common procedure that involves passing a tube through the nose and into the stomach for various purposes, such as feeding, decompression, or medication administration. While it is an invasive procedure, it is often performed in emergency or critical care situations where the client's immediate well-being takes precedence. Informed consent may not be feasible or necessary in these situations, depending on the context and urgency.
