What type of cells secrete insulin?

Alpha cells

Beta cells

Acinar cells

Plasma cells

Answer and Explanation

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 B

Explanation

B. An elevated white blood cell (WBC) count, specifically an elevation in the neutrophil count (neutrophilia), is commonly seen in pneumonia. It indicates an inflammatory response to the infection and is a typical finding in bacterial pneumonia.
A. A decreased serum creatinine level is not typically associated with pneumonia and may not be directly related to the condition. In fact, it may suggest impaired kidney function or dehydration, but it is not a concerning lab abnormality specifically related to pneumonia.
C. Protein in the urine (proteinuria) may be present in various conditions, including kidney disease, urinary tract infections, and certain systemic illnesses. While it can sometimes be seen in severe cases of pneumonia, it is not a specific or common finding associated with the condition.
D. Decreased serum potassium levels are not typically associated with pneumonia itself. However, certain factors related to pneumonia treatment or complications, such as the use of diuretics or vomiting, could lead to hypokalemia. While hypokalemia can have serious consequences, it is not directly related to the severity of pneumonia.

A. Tremor B. Lethargy C. Seizures D. Polydipsia E. Abdominal pain F. Sweating G. Polyuria H. Hunger

Explanation

Hypoglycemia

Tremor is a common symptom of hypoglycemia, as low blood sugar levels can lead to shaky hands and trembling.

Seizures can occur in severe cases of hypoglycemia when the brain is deprived of glucose, leading to abnormal electrical activity and convulsions.

Sweating, particularly cold and clammy skin, is a common symptom of hypoglycemia as the body responds to low blood sugar levels.

Hunger or sudden feelings of extreme hunger are common symptoms of hypoglycemia as the body seeks additional fuel to raise blood sugar levels.

Hyperglycemia

Lethargy, or extreme fatigue and drowsiness, is more commonly associated with hyperglycemia, as elevated blood sugar levels can affect energy levels and lead to feelings of sluggishness.

Polydipsia is a classic symptom of hyperglycemia, as high blood sugar levels can cause dehydration and trigger the body's thirst response.

Abdominal pain is more commonly associated with hyperglycemia, particularly in conditions like diabetic ketoacidosis (DKA), where abdominal discomfort can be a sign of metabolic disturbances.

Polyuria is a classic symptom of hyperglycemia, as high blood sugar levels can lead to increased urine production as the kidneys work to remove excess glucose from the bloodstream.
