INTRODUCTION
*
This comprehensive assessment is designed to evaluate advanced nursing knowledge of
endocrine and metabolic disorders addressed in NUR 6121 Module 3. The questions assess
foundational concepts, clinical assessment, diagnostic interpretation, disease mechanisms,
treatment principles, prevention, patient education, and clinical decision-making. Multiple-
choice questions are used to distinguish closely related concepts and to develop the ability to
apply knowledge to realistic primary-care situations. Particular emphasis is placed on
diabetes mellitus, metabolic syndrome, obesity, and thyroid disorders. Effective preparation
requires understanding why findings, laboratory values, treatments, and interventions are
appropriate rather than relying solely on memorization. The assessment therefore
progresses from foundational knowledge to application and clinical reasoning.

SECTION ONE: QUESTIONS 1–100
Question 1. Which pathophysiologic process is most characteristic of type 1 diabetes
mellitus?
A. Progressive insulin resistance with preserved endogenous insulin production
B. Autoimmune destruction of pancreatic beta cells resulting in absolute insulin deficiency
C. Excessive hepatic glucose uptake caused by hyperinsulinemia
D. Increased insulin secretion caused by peripheral glucose resistance
Correct Answer: B. Autoimmune destruction of pancreatic beta cells resulting in absolute
insulin deficiency
,Explanation: Type 1 diabetes mellitus results primarily from autoimmune destruction of
pancreatic beta cells, producing progressive and ultimately near-complete insulin deficiency.
This distinguishes type 1 diabetes from type 2 diabetes, in which insulin resistance and
progressive beta-cell dysfunction predominate.
Question 2. Which feature most strongly distinguishes type 2 diabetes mellitus from type 1
diabetes mellitus?
A. Dependence on insulin for survival from the time of diagnosis
B. Frequent association with autoimmune beta-cell destruction
C. Primary development through insulin resistance and progressive beta-cell dysfunction
D. Consistent presentation with diabetic ketoacidosis
Correct Answer: C. Primary development through insulin resistance and progressive beta-cell
dysfunction
Explanation: Type 2 diabetes is characterized initially by insulin resistance accompanied by
inadequate compensatory insulin secretion. Beta-cell function progressively declines over
time. Although insulin may eventually be required, insulin dependence at diagnosis is not
the defining feature.
Question 3. Which patient finding is most suggestive of hyperglycemia?
A. Polyuria and polydipsia
B. Bradycardia and hypothermia
C. Constipation and dry skin
D. Tremor and heat intolerance
Correct Answer: A. Polyuria and polydipsia
Explanation: Hyperglycemia increases urinary glucose excretion, producing osmotic diuresis
and polyuria. Increased fluid loss stimulates thirst, resulting in polydipsia. Tremor and heat
intolerance are more consistent with hyperthyroidism.
Question 4. Hemoglobin A1C is particularly useful in diabetes management because it:
A. Measures pancreatic insulin production directly
B. Reflects average glycemic exposure over approximately the previous 2–3 months
C. Determines whether a patient has diabetic ketoacidosis
D. Measures blood glucose only during fasting
Correct Answer: B. Reflects average glycemic exposure over approximately the previous 2–3
months
Explanation: Hemoglobin A1C reflects the proportion of hemoglobin that has undergone
glycation over the lifespan of circulating red blood cells, providing an estimate of average
glycemic exposure over roughly the preceding 2–3 months.
,Question 5. Which factor can make hemoglobin A1C less reliable as a measure of glycemic
control?
A. Stable red blood cell survival
B. Normal hemoglobin structure
C. Conditions that substantially alter red blood cell turnover
D. Consistent daily glucose levels
Correct Answer: C. Conditions that substantially alter red blood cell turnover
Explanation: Hemoglobin A1C depends on the time available for hemoglobin glycation.
Hemolysis, recent blood loss, transfusion, and other conditions affecting red blood cell
survival can therefore produce an A1C that does not accurately represent typical glucose
exposure.
Question 6. A patient with newly diagnosed type 2 diabetes asks why lifestyle modification is
emphasized even when medication is prescribed. Which response is most appropriate?
A. “Lifestyle modification eliminates the need for all diabetes medications.”
B. “Dietary activity and weight management can improve insulin sensitivity and overall
cardiometabolic risk.”
C. “Exercise is recommended primarily to prevent hypoglycemia.”
D. “Lifestyle changes affect cholesterol but have little effect on glucose control.”
Correct Answer: B. “Dietary activity and weight management can improve insulin sensitivity
and overall cardiometabolic risk.”
Explanation: Nutrition, physical activity, sleep, and weight management can improve insulin
sensitivity, glycemic control, blood pressure, lipid status, and cardiovascular risk. Lifestyle
modification complements rather than universally replaces pharmacologic treatment.
Question 7. Which complication of diabetes is classified as a microvascular complication?
A. Coronary artery disease
B. Peripheral arterial disease
C. Diabetic nephropathy
D. Ischemic stroke
Correct Answer: C. Diabetic nephropathy
Explanation: Diabetic nephropathy, retinopathy, and neuropathy are classic microvascular
complications. Coronary artery disease, peripheral arterial disease, and ischemic stroke are
primarily macrovascular complications associated with diabetes.
Question 8. Which symptom is most characteristic of diabetic peripheral neuropathy?
A. Bilateral burning or tingling of the feet
B. Sudden unilateral hearing loss
, C. Persistent productive cough
D. Acute neck swelling
Correct Answer: A. Bilateral burning or tingling of the feet
Explanation: Peripheral neuropathy commonly causes distal symmetric sensory symptoms
such as burning, tingling, numbness, altered sensation, or pain, especially in the feet. Loss of
protective sensation also increases the risk of unnoticed foot injury.
Question 9. Which assessment is particularly important during routine diabetes follow-up to
identify peripheral neuropathy?
A. Visual acuity only
B. Foot inspection and sensory assessment
C. Abdominal percussion
D. Thyroid palpation only
Correct Answer: B. Foot inspection and sensory assessment
Explanation: Diabetes can cause sensory loss and vascular impairment that predispose
patients to ulcers and infection. Routine foot inspection and assessment of protective
sensation are therefore essential components of diabetes care.
Question 10. Which finding should raise concern for diabetic nephropathy?
A. Albuminuria
B. Low serum sodium caused by vomiting
C. Increased visual acuity
D. Decreased thyroid-stimulating hormone
Correct Answer: A. Albuminuria
Explanation: Increased urinary albumin excretion is an important marker of diabetic kidney
involvement. Early detection allows interventions that can slow progression of chronic
kidney disease.
Question 11. A patient with diabetes reports a painless blister on the plantar surface of the
foot. What is the most appropriate interpretation?
A. The absence of pain excludes clinically important disease.
B. The lesion may reflect loss of protective sensation and requires prompt evaluation.
C. Blisters are expected and do not require assessment in diabetes.
D. The lesion confirms hyperthyroidism.
Correct Answer: B. The lesion may reflect loss of protective sensation and requires prompt
evaluation.
