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

Option A (Place the infant in reverse Trendelenburg position) and option B (Place the infant in the knee to chest position) are not the immediate actions to address this situation. While these positions might be used in specific situations, assessing blood pressure is more appropriate in this context to evaluate for potential vascular issues.

Option C. Take the infant's blood pressure in all extremities.

In an infant with weaker femoral pulses compared to the brachial and radial pulses, there might be a concern about coarctation of the aorta (a narrowing of the aorta), which can affect blood flow to the lower extremities. To confirm this and assess for potential issues, taking blood pressure measurements in all four extremities is crucial. This comparison can help identify pressure differentials between the upper and lower extremities, which is a hallmark sign of coarctation of the aorta.

Option D (Notify the Physician) is generally a good step, but taking the blood pressure in all extremities should be done first to provide comprehensive information for the physician when discussing the infant's condition.

A. Fever B. Unwillingness to move affected extremity. C. Previous closed fracture of an extremity D. Redness and swelling at the site E. Severe pain

Correct Answer is ["A","B","D","E"]

Explanation

A. Fever: Osteomyelitis is often associated with fever as it is an infectious process that can cause an elevated body temperature.

B. Unwillingness to move the affected extremity: Children with osteomyelitis may experience pain and discomfort, leading to a reluctance to move the affected limb.

C. A previous closed fracture of an extremity is not typically a direct assessment finding for osteomyelitis. Osteomyelitis is more commonly associated with infections that can spread to the bone, and a previous fracture may not always be present.

D. Redness and swelling at the site: Osteomyelitis can cause local inflammation, leading to redness and swelling at the affected area.

E. Severe pain: Pain is a common symptom of osteomyelitis, and it can be severe, leading to the child's unwillingness to move the affected extremity.
