17-year-old student with type 1 diabetes asks the nurse which hormone causes the blood glucose level to rise. When responding the nurse should explain in language that the client can understand that liver glycogenolysis is stimulated by a hormone secreted by the islets of Langerhans Which hormone is this?

Insulin

Epinephrine

Glucagon

Adrenocorticotropic hormone (ACTH)

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is C

Explanation

A. Continuing to offer a special formula to limit gagging is not a standard approach in the care of infants with cerebral palsy. The choice of formula should be based on the child's nutritional needs, and any feeding difficulties should be addressed by a healthcare professional.

B. Maintaining immobility of the limbs with splints is not recommended. Encouraging movement and mobility is important for the development and well-being of children with cerebral palsy.

C. Preserve muscle tone to prevent joint contractures.

Cerebral palsy is a condition that can lead to problems with muscle tone and movement. Preserving muscle tone is important to prevent joint contractures, which can limit mobility and cause pain. Physical therapy and exercises can help maintain muscle tone and joint flexibility in children with cerebral palsy.

D. Focusing on cognitive rather than motor skills is not appropriate. Motor skills are a crucial aspect of development for children with cerebral palsy. The approach should encompass both cognitive and motor skill development as appropriate for the child's age and abilities.

A. The body's response to gluten causes the intestine to become more porous and hang on to more of the fat-soluble vitamins, leading to vitamin toxicity." B. "The body's response to gluten causes damage to the mucosal cells in the intestines leading to absorption problems C. "The body's response to consumption of anything containing gluten is to create special cells called villi, which leads to more diarrhea D. "The body's response to gluten causes damage to the mucosal cells, leading to malabsorption of water and hard, constipated stools

Correct Answer is B

Explanation

A. "The body's response to gluten causes the intestine to become more porous and hang on to more of the fat-soluble vitamins, leading to vitamin toxicity." This answer is not accurate. The issue in celiac disease is malabsorption, not vitamin toxicity.

B. "The body's response to gluten causes damage to the mucosal cells in the intestines leading to absorption problems."

Celiac disease is an autoimmune disorder in which the ingestion of gluten (a protein found in wheat, barley, and rye) leads to damage of the mucosal cells in the small intestine. This damage, in turn, can lead to malabsorption of essential nutrients, including vitamins, minerals, and other important components of the diet. It is important for individuals with celiac disease to avoid gluten-containing foods to prevent ongoing damage to the intestinal mucosa and improve nutrient absorption.

C. "The body's response to consumption of anything containing gluten is to create special cells called villi, which leads to more diarrhea." This statement is not accurate. Celiac disease leads to damage to the villi (finger-like projections) in the small intestine, not the creation of special cells. It can lead to diarrhea but is not the primary cause.

D. "The body's response to gluten causes damage to the mucosal cells, leading to malabsorption of water and hard, constipated stools." This response is not accurate. Celiac disease is more commonly associated with diarrhea and malabsorption, not constipation and malabsorption of water.
