How to Use This Guide
Read each stem, choose your answer, then check the rationale directly below it. The correct
option is marked, and each wrong option is explained so you understand why it's wrong — not
just that it is. Each question is derived directly from NSG 555 Quiz 2 course content and
formatted in exam style.

Review
1 What is the definition of diabetes?
A A group of metabolic diseases characterized by hyperglycemia resulting from
defects in insulin secretion, insulin action, or both
B A disease caused by insufficient glucagon production
C A condition of elevated triglycerides only
D A disease resulting from excessive insulin secretion
Why A is correct: Diabetes is a group of metabolic diseases characterized by
hyperglycemia resulting from defects in insulin secretion, insulin action, or both.
B — Glucagon deficiency is not the definition of diabetes.
C — Elevated triglycerides alone do not define diabetes.
D — Excessive insulin secretion is not the definition.
,2 What causes Type 1 Diabetes Mellitus (DM)?
A Autoimmune destruction of the beta cells within the islets of Langerhans in the
pancreas, leading to insulinopenia and lifelong dependence on exogenous insulin
B Insulin resistance and metabolic syndrome
C Beta cell exhaustion from overproduction of insulin
D Pancreatic alpha cell dysfunction
Why A is correct: Type 1 DM is caused by autoimmune destruction of beta cells in the
pancreas, leading to insulinopenia and lifelong dependence on exogenous insulin.
B — Insulin resistance is characteristic of Type 2 DM.
C — Beta cell exhaustion is associated with Type 2 DM.
D — Alpha cell dysfunction is not the cause of Type 1 DM.
3 How does the onset of Type 1 DM differ in children and adults?
A It is more rapid in infants and children and more gradual in adults
B It is more gradual in infants and children and more rapid in adults
C Onset is the same in all age groups
D It only occurs in children
Why A is correct: The onset of Type 1 DM is more rapid in infants and children and more
gradual in adults.
B — The pattern is reversed; children have more rapid onset.
C — Onset varies by age.
D — Type 1 DM can occur at any age.
, 4 What characterizes Type 2 Diabetes Mellitus (DM)?
A Insidious onset with progressive insulin resistance, often associated with prediabetes
and metabolic syndrome
B Sudden onset with autoimmune destruction of beta cells
C Lifelong dependence on exogenous insulin from onset
D Always presents with diabetic ketoacidosis
Why A is correct: Type 2 DM has an insidious onset with progressive insulin resistance,
often associated with prediabetes and metabolic syndrome.
B — Sudden onset with autoimmune destruction is Type 1 DM.
C — Lifelong insulin dependence is Type 1 DM.
D — DKA is more common in Type 1 DM.
5 List some symptoms of Type 2 DM.
A Abdominal obesity, insulin resistance, hyperglycemia, elevated triglycerides, low HDL
levels, hypertension, and a proinflammatory state
B Polyuria, polydipsia, polyphagia, and weight loss
C Ketoacidosis and rapid weight loss
D Only hyperglycemia
Why A is correct: Type 2 DM symptoms include abdominal obesity, insulin resistance,
hyperglycemia, elevated triglycerides, low HDL, hypertension, and a proinflammatory state.
B — Polyuria, polydipsia, polyphagia, and weight loss are symptoms of Type 1 DM.
C — Ketoacidosis is more common in Type 1 DM.
D — Hyperglycemia is one symptom among many.
