Which hormone lowers blood glucose levels by facilitating cellular uptake of glucose?
Insulin
Glucagon
Adrenaline
Thyroxine
Insulin is the primary anabolic hormone that lowers blood glucose levels. It is secreted by the pancreatic beta cells in response to elevated glucose. Insulin facilitates the uptake of glucose into muscle and adipose tissue, promoting energy storage and utilization. CDC on insulin.
Which type of diabetes is characterized by autoimmune destruction of pancreatic beta cells?
Type 1 diabetes
Type 2 diabetes
Gestational diabetes
Prediabetes
Type 1 diabetes results from autoimmune destruction of the pancreatic beta cells, leading to absolute insulin deficiency. It commonly presents in children and young adults but can occur at any age. Unlike type 2 diabetes, it is not primarily linked to obesity or lifestyle factors. WHO on diabetes types.
What is the normal range for fasting blood glucose in adults?
70-100 mg/dL
50-70 mg/dL
100-126 mg/dL
126-200 mg/dL
Normal fasting blood glucose in adults ranges between 70 and 100 mg/dL. Values above this range may indicate impaired glucose tolerance or diabetes. The ADA uses these thresholds to guide diagnosis and treatment plans. ADA diagnosis criteria.
Which organ is primarily responsible for producing insulin?
Pancreas
Liver
Gallbladder
Adrenal gland
The pancreas contains clusters of cells called islets of Langerhans, where insulin is produced by beta cells. Insulin is critical for regulating blood glucose and maintaining metabolic balance. Other organs do not synthesize this hormone. NIH pancreas physiology.
The HbA1c test reflects average blood glucose levels over approximately how many months?
2-3 months
1 month
6 months
12 months
HbA1c reflects the average blood glucose concentration by measuring the percentage of glycated hemoglobin. Since red blood cells live about 120 days, the test provides a 2-3 month glucose history. It is used clinically to monitor and adjust long-term diabetes management. ADA on A1c.
Which of the following is the strongest risk factor for developing type 2 diabetes?
Obesity
Viral infection
Autoimmune disease
Low-carbohydrate diet
Obesity is the strongest modifiable risk factor for type 2 diabetes, as excess adipose tissue leads to insulin resistance. Although genetics play a role, lifestyle and weight contribute heavily to disease progression. Reducing body weight can significantly lower diabetes risk. WHO on obesity.
Diabetic retinopathy affects which part of the body?
Eyes
Kidneys
Nerves
Heart
Diabetic retinopathy is a microvascular complication of diabetes that damages the retina in the eyes. Chronic hyperglycemia affects the tiny blood vessels, leading to vision impairment and potentially blindness. Early detection and glycemic control are critical to prevent progression. NEI retinopathy.
Gestational diabetes occurs during which period?
Pregnancy
Childhood
Menopause
Old age
Gestational diabetes is glucose intolerance first recognized during pregnancy, usually in the second or third trimester. Hormonal changes and increased insulin resistance contribute to elevated blood glucose. It typically resolves after delivery but raises risk for type 2 diabetes later. CDC gestational diabetes.
Which class of oral diabetes medications works primarily by decreasing hepatic glucose production and improving insulin sensitivity?
Biguanides
Sulfonylureas
DPP-4 inhibitors
SGLT2 inhibitors
Biguanides, such as metformin, are first-line medications for type 2 diabetes. They lower blood glucose by reducing hepatic gluconeogenesis and improving peripheral insulin sensitivity. This class does not stimulate insulin secretion, lowering risk of hypoglycemia. NIH on metformin.
Diabetic ketoacidosis is primarily characterized by which of the following?
Increased ketone bodies and metabolic acidosis
Hypoglycemia
Hyperosmolarity without ketosis
Excess insulin secretion
Diabetic ketoacidosis is marked by the accumulation of ketone bodies and a high anion gap metabolic acidosis. It arises from absolute or relative insulin deficiency and counterregulatory hormone excess. Patients typically present with hyperglycemia, dehydration, and electrolyte imbalances. NKF on DKA.
According to ADA guidelines, statin therapy is recommended for diabetic patients over what age to reduce cardiovascular risk?
40 years
30 years
50 years
60 years
According to the ADA, adults aged 40 to 75 years with diabetes should be on statin therapy to reduce cardiovascular risk. Statins help lower LDL cholesterol and stabilize atherosclerotic plaques. Age-based recommendations target primary prevention in this high-risk group. ADA statin guidelines.
What is the gold standard test for diagnosing gestational diabetes according to WHO?
75 g oral glucose tolerance test
Fasting plasma glucose
HbA1c
Random plasma glucose
The WHO recommends a 75 g oral glucose tolerance test (OGTT) as the diagnostic standard for gestational diabetes. Plasma glucose is measured fasting and 2 hours post-load to assess glucose tolerance. Abnormal thresholds help identify patients who need intervention during pregnancy. WHO diagnostic criteria.
Which human leukocyte antigen (HLA) haplotype is most closely associated with increased risk of type 1 diabetes?
HLA-DR3/DR4
HLA-B27
HLA-DQ2
HLA-A2
Specific HLA class II molecules on antigen-presenting cells are strongly linked to type 1 diabetes susceptibility. The combined presence of HLA-DR3 and HLA-DR4 alleles greatly increases risk. These haplotypes influence autoimmune targeting of pancreatic beta cells. NIH on HLA and type 1 diabetes.
SGLT2 inhibitors lower blood glucose by which primary mechanism?
Inhibiting renal glucose reabsorption
Stimulating insulin secretion
Decreasing intestinal glucose absorption
Enhancing peripheral glucose uptake
SGLT2 inhibitors work by blocking the sodium-glucose co-transporter 2 in the proximal renal tubules. This reduces glucose reabsorption and increases urinary glucose excretion. The resulting glycosuria lowers plasma glucose independent of insulin pathways. NIH on SGLT2 inhibitors.

Cheat Sheet
Diagnostic Thresholds -
Memorize ADA and WHO cutoffs: fasting plasma glucose ≥126 mg/dL, 2-hour OGTT ≥200 mg/dL, or HbA1c ≥6.5% (ADA 2023). A handy mnemonic is "126 - 200 - 6.5" to cement these numbers for your quiz on diabetes. This anchors your recall when you face diabetes trivia questions or MCQ diabetes quiz items.
Types of Diabetes -
Differentiate Type 1 (autoimmune β-cell destruction), Type 2 (insulin resistance), and gestational diabetes (screen at 24 - 28 weeks via OGTT). Use "IDM" (Insulin deficiency, DM type 2, Maternal) as a trigger for risk factors in "do I have gestational diabetes quiz" contexts. Recognizing these types helps you tackle any diabetes facts quiz with confidence.
Understanding HbA1c & eAG -
Learn the relationship: eAG (mg/dL) = 28.7×HbA1c(%) − 46.7, and know that each 1% A1c change ≈29 mg/dL in average glucose (Nathan et al., 2008). This formula is fundamental for interpreting long-term glycemic control in exams and clinical scenarios. Practice converting A1c values so you shine in any MCQ diabetes quiz.
Acute Complications & Mnemonics -
Distinguish diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) using the "4 Ds" (Dehydration, Diuresis, Drowsiness, Dyspnea). Recognizing symptom clusters and lab findings (e.g., pH <7.3 in DKA) is key for rapid recall. This trick is perfect for speeding through diabetes trivia questions under time pressure.
Lifestyle Management & Hypoglycemia Rule of 15 -
Master the Rule of 15: ingest 15 g of fast-acting carbs, wait 15 minutes, then recheck glucose (ADA, 2022). Link this to meal planning strategies (plate method: half veggies, quarter lean protein, quarter grains) to reinforce prevention concepts. Armed with these tips, you'll breeze through a diabetes facts quiz or any quiz on diabetes prevention topics.
