Which of the following Reticulocyte count is an indicator of severe anemia for an infant?

A. Alertness as such weight loss is not expected: This response may unnecessarily alarm the mother when, in fact, some weight loss in the early days is normal.

B. Reassurance as this is a normal weight loss.

It is normal for newborns to lose some weight during the first few days of life. The loss is often related to fluid loss, changes in feeding patterns, and initial adjustment to life outside the womb. A loss of one-half pound in a 2-day-old neonate is generally considered within the normal range. It's important for the nurse to reassure the new mother that this weight loss is expected and not a cause for alarm. Newborns typically start to regain their birth weight within a week or two. This reassurance can help ease the mother's distress and anxiety.

C. Alarm as this is a drastic weight loss: Characterizing this weight loss as "drastic" is not accurate or helpful and would likely increase the mother's anxiety.

D. Concern as this may be an indicator of inadequate nutrition: Jumping to the conclusion of inadequate nutrition without further assessment and evidence is premature and may unnecessarily worry the mother. It's important to start with reassurance and then investigate if there are concerns about nutrition.

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.
