What type of cells secrete glucagon?
Plasma cells
Acinar cells
Beta cells
Alpha cells
The Correct Answer is D
D. Alpha cells, also known as A cells, are a type of pancreatic islet cell (or islet of Langerhans cell) that secretes glucagon. Glucagon plays a crucial role in increasing blood sugar levels by promoting the breakdown of glycogen in the liver and stimulating the release of glucose into the bloodstream.
A. 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 glucagon.
B. 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 glucagon.
C. Beta cells are another type of cell in the pancreas, but they secrete insulin, not glucagon. Insulin is responsible for lowering blood sugar levels by promoting the uptake of glucose into cells for energy or storage.

Correct Answer is ["B","D","E"]
Explanation
B. Bronchodilators are medications commonly used to relieve bronchospasm and improve airflow in patients with COPD. They work by relaxing the muscles around the airways, making it easier to breathe. Providing bronchodilators as prescribed can help alleviate difficulty breathing and improve the patient's respiratory function.
D. Smoking cessation is essential for patients with COPD as smoking is the leading cause of the disease and can exacerbate respiratory symptoms. Quitting smoking can slow the progression of COPD, reduce the frequency and severity of exacerbations, and improve overall lung function.
E. Corticosteroids are anti-inflammatory medications commonly used to reduce airway inflammation and control exacerbations in patients with COPD. They can help improve breathing and reduce the severity of respiratory symptoms during acute exacerbations.
A. Offering small frequent meals can help reduce the sensation of fullness and bloating, which can sometimes occur in patients with COPD due to increased abdominal pressure from compromised respiratory function. However, this is not specific to COPD.
C. Weaning from oxygen should be done cautiously and under the guidance of healthcare providers but not in the state of difficulty in breathing. Oxygen therapy is often necessary for patients with COPD who experience difficulty breathing, especially during acute exacerbations. Therefore, weaning from oxygen may be appropriate once the patient's respiratory status stabilizes and oxygen saturation levels improve.
Correct Answer is D
Explanation
D. Obesity and weight loss are more directly linked to type 2 diabetes but they are not primary factors in the management of type 1 diabetes. Type 1 diabetes is characterized by the autoimmune destruction of beta cells, leading to an absolute deficiency of insulin. Weight loss can improve insulin sensitivity, which might be relevant for type 2 diabetes or insulin resistance, but type 1 diabetes patients will always require exogenous insulin regardless of weight changes.
A. Patients with type 1 diabetes are at risk for diabetic ketoacidosis (DKA), a serious condition caused by high blood glucose levels and ketone buildup due to insufficient insulin. Monitoring blood glucose levels is crucial in preventing DKA.
B. Type 1 diabetes is an autoimmune disease where the immune system attacks the insulin- producing beta cells in the pancreas. A viral infection can sometimes trigger this autoimmune response in genetically susceptible individuals.
C. There is a genetic component to type 1 diabetes, and having a family history of the disease can increase the risk, although environmental factors also play a role.
