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)
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 ["B","C"]
Explanation
Iron-rich foods that should be recommended for a toddler with iron deficiency anemia include:
B. Chicken: Chicken, especially dark meat, is a good source of heme iron, which is easily absorbed by the body.
C. Lean Steak: Lean beef, such as steak, is also a good source of heme iron.
Non-heme iron from plant-based sources is also beneficial but is generally less easily absorbed. So, the following options are non-heme iron sources:
A. Broccoli: While broccoli contains iron, it is a non-heme iron source. It can still contribute to iron intake, but it's not as efficient as heme iron from animal sources.
D. Carrots: Similar to broccoli, carrots contain non-heme iron, but they can be part of a balanced diet for increasing iron intake.
E. Whole Milk: Whole milk can interfere with iron absorption in the body. It's not recommended for children with iron deficiency anemia, as it can make the condition worse. It's better to choose lower-fat milk or alternative milk sources.
Additionally, other sources of iron-rich foods for toddlers can include fortified cereals, legumes (like lentils and beans), and fortified infant formulas if needed. Always consult with a healthcare provider for specific dietary recommendations based on the child's condition.
Correct Answer is ["A","B","C","E"]
Explanation
A. Monitoring level of consciousness (LOC): Monitoring the child's level of consciousness is essential as changes in LOC can be an important indicator of the progression of meningitis.
B. Administration of IV antibiotics: Antibiotics are a critical component of the treatment for bacterial meningitis. Early administration of appropriate antibiotics is crucial to control the infection.
C. Decreasing environmental stimuli: Reducing environmental stimuli, such as noise and light, can help minimize discomfort and agitation in a child with meningitis.
D. Increasing IV fluids above maintenance is not typically part of the standard management of bacterial meningitis. Maintaining hydration and electrolyte balance is important, but increasing fluids significantly above maintenance may not be necessary and should be determined based on the child's clinical condition.
E. Instituting droplet precautions: Bacterial meningitis is contagious, and it is important to isolate the child and implement appropriate infection control measures, including droplet precautions, to prevent the spread of the infection to others.
