What is your explanation to the parents who do not want to give their child insulin injections to treat type 1 diabetes because they have heard that pills can be used to treat this condition?
The child cannot take the pills because we can't be sure that he would take the entire dose.
The pills are reserved for those over the age of 12.
Insulin is destroyed in the gastrointestinal tract if taken orally, so it must be injected subcutaneously.
The child can go ahead and take the oral medication because he does have type 1 diabetes.
The Correct Answer is C
Choice A reason: This explanation is not correct. The reason why oral medications are not used for type 1 diabetes is not related to the child's ability to take the entire dose. The primary issue is the nature of insulin and how it must be administered.
Choice B reason: This statement is incorrect. The use of insulin injections is not based on age but on the type of diabetes. Type 1 diabetes requires insulin therapy regardless of the patient's age.
Choice C reason: Insulin is a protein that, if taken orally, would be broken down by the digestive enzymes in the gastrointestinal tract, rendering it ineffective. For this reason, insulin must be administered through subcutaneous injections to ensure it reaches the bloodstream intact and can effectively regulate blood glucose levels.

Correct Answer is C
Explanation
Choice A reason: Positive feedback mechanisms amplify changes or deviations in the body. They are less common in physiological processes and typically drive processes to completion, such as childbirth and blood clotting. The regulation of blood glucose levels does not operate on a positive feedback mechanism.
Choice B reason: Releasing hormones are typically involved in the hypothalamic-pituitary axis and the regulation of hormone secretion from other endocrine glands. Examples include thyrotropin-releasing hormone (TRH) and gonadotropin-releasing hormone (GnRH). Insulin secretion in response to blood glucose levels is not directly controlled by releasing hormones.
Choice C reason: Negative feedback is the primary mechanism by which homeostasis is maintained in the body. When blood glucose levels rise, the pancreas secretes insulin to lower blood glucose levels, restoring them to normal. This is an example of negative feedback, as the increase in glucose levels triggers a response (insulin secretion) that counteracts the initial change, bringing blood glucose back to its set point.
Choice D reason: Ectopic hormones are hormones produced by tissues that normally do not produce hormones, often in cases of tumors or certain disease conditions. The regulation of insulin in response to blood glucose levels does not involve ectopic hormone production.
Correct Answer is D
Explanation
Choice A reason: Fasting blood glucose measures the blood sugar level after an individual has not eaten for at least 8 hours. While it provides a snapshot of current blood glucose levels, it does not reflect long-term blood glucose control.
Choice B reason: Urinalysis can detect the presence of glucose or ketones in the urine, which can indicate poor blood glucose control. However, it does not provide a direct measure of blood glucose levels over time and is not the best predictor of long-term control.
Choice C reason: Feasting (postprandial) blood glucose measures blood sugar levels after eating. It can indicate how well the body manages glucose after a meal but does not provide information about overall blood glucose control over the previous few months.
Choice D reason: Hemoglobin A1C, also known as HbA1c, measures the percentage of glycated hemoglobin in the blood. It reflects the average blood glucose levels over the past 2-3 months. This test is considered the best predictor of long-term blood glucose control because it provides a comprehensive view of blood sugar management over an extended period. The normal range for HbA1c is typically below 5.7% for individuals without diabetes.
