What type of cells secrete insulin?
Alpha cells
Beta cells
Acinar cells
Plasma cells
The Correct Answer is B
B. Beta cells are the pancreatic cells responsible for secreting insulin. Insulin acts to lower blood sugar levels by facilitating the uptake of glucose into cells for energy or storage. In individuals with diabetes mellitus, dysfunction of beta cells can lead to inadequate insulin secretion, resulting in high blood sugar levels.
A. Alpha cells are another type of cell in the pancreas, but they secrete glucagon, not insulin. Glucagon has the opposite effect of insulin, increasing blood sugar levels by stimulating the breakdown of glycogen in the liver.
C. Acinar cells are exocrine cells found in the pancreas that secrete digestive enzymes into the pancreatic ducts. These enzymes aid in the digestion of food in the small intestine. Acinar cells are not involved in the production of insulin.
D. Plasma cells are a type of white blood cell that produces antibodies as part of the immune response. They are not involved in the production of insulin.

Correct Answer is C
Explanation
C. Monitoring blood sugar levels regularly, as recommended by the doctor, is crucial for managing type 2 diabetes effectively. It helps patients track their glucose levels, identify patterns, and make informed decisions about medication, diet, and lifestyle choices to maintain optimal blood sugar control.
A. Drinking orange juice to treat high blood sugar is not recommended because it can cause a rapid increase in blood sugar levels due to its high sugar content. Instead, patients should focus on consuming foods or beverages with lower glycemic index values and more stable glucose responses.
B. Regular physical activity is an essential component of diabetes management as it helps improve insulin sensitivity, lower blood sugar levels, control weight, and reduce the risk of complications. Patients with diabetes are encouraged to engage in regular exercise as part of their overall treatment plan.
D. Eating a diet high in carbohydrates can lead to spikes in blood sugar levels, which can be detrimental for individuals with type 2 diabetes. Instead, patients are encouraged to follow a balanced diet that includes a variety of nutrient-rich foods, with a focus on whole grains, lean proteins, healthy fats, fruits, and vegetables, while moderating carbohydrate intake.
Correct Answer is A
Explanation
A. Chocolate contains caffeine and cocoa, both of which can relax the lower esophageal sphincter (LES) and increase the risk of acid reflux. Additionally, chocolate is high in fat, which can further exacerbate symptoms of GERD. Therefore, chocolate is often recommended to be avoided by individuals with GERD.
B. Oatmeal is generally considered a bland and low-acid food that is unlikely to trigger symptoms of GERD. In fact, oatmeal is often recommended as part of a GERD-friendly diet due to its high fiber content, which can help absorb stomach acid and promote digestive health.
C. Apples are generally considered to be low in acid and high in fiber, making them a relatively safe fruit choice for individuals with GERD. However, some individuals may find that certain varieties of apples or apple products (such as apple juice) can exacerbate their GERD symptoms.
D. Nonfat milk is generally considered to be a low-fat and low-acid beverage that is unlikely to trigger symptoms of GERD. However, some individuals may find that consuming dairy products, including milk, can exacerbate their GERD symptoms.
