The nurse is caring for a 2-year-old who is lethargic and irritable after brain tumor surgery. She is noted to have dry mucous membranes and high urinary output. She has had 2 generalized seizures in the past hour. Which of the following is likely causing these symptoms?

A. Administration of a systemic oral antibiotic and a topical antibiotic may be used, but this option does not address the removal of crusts, which is essential for preventing complications.

B. Administration of a systemic and a topical antifungal is not appropriate for impetigo, as impetigo is caused by bacteria, not fungi.

C. Using an oil-based soap for bathing is not recommended, as it may not effectively remove crusts and pustules associated with impetigo, and it does not have antimicrobial properties necessary for treatment.

D. Removal of crusts with an antimicrobial liquid.

Impetigo is a contagious bacterial skin infection, typically caused by Staphylococcus aureus or Streptococcus pyogenes. It often presents with crusts and pustules on the skin. To prevent complications, it's important to keep the affected areas clean and free from crusts. Gently removing crusts with an antimicrobial liquid and clean cloth helps prevent the spread of infection, allows topical antibiotics to work effectively, and reduces the risk of complications.

A. Insulin is responsible for lowering blood glucose levels by promoting the uptake and storage of glucose in cells.

B. Epinephrine (adrenaline) can raise blood glucose levels in response to the "fight or flight" stress response, but it's not primarily responsible for stimulating liver glycogenolysis.

C. Glucagon is produced by the alpha cells in the islets of Langerhans and plays a crucial role in increasing blood glucose levels. It promotes the breakdown of glycogen (glycogenolysis) in the liver and the production of glucose from non-carbohydrate sources (gluconeogenesis).

D. Adrenocorticotropic hormone (ACTH) is produced by the anterior pituitary gland and stimulates the adrenal cortex to release cortisol, which can also contribute to raising blood glucose levels but isn't primarily responsible for liver glycogenolysis.

In the context of diabetes management, understanding the role of glucagon is important because it helps individuals know how to manage hypoglycemia (low blood sugar) by administering glucagon or consuming fast-acting sources of glucose.
