1. A patient with newly diagnosed type 1 diabetes mellitus asks why
insulin therapy is required even though they have recently started
exercising and changed their diet. Which explanation by the
diabetes educator is most accurate?
A. Exercise permanently replaces pancreatic insulin production.
B. Type 1 diabetes is primarily caused by excessive carbohydrate intake.
C. Type 1 diabetes involves destruction or severe loss of pancreatic
beta-cell function, resulting in inadequate endogenous insulin
production.
D. Insulin is required only until the patient loses excess weight.
Answer: C
Rationale: Type 1 diabetes results from progressive destruction of
pancreatic beta cells and ultimately produces absolute or near-
absolute insulin deficiency. Lifestyle modification is extremely
important for overall health but cannot replace the insulin required
for survival.
2. A patient has a fasting plasma glucose of 132 mg/dL on one
occasion but reports no symptoms of hyperglycemia. What is the
most appropriate interpretation?
1
,A. This automatically confirms diabetes.
B. The result is in the diabetes range, but in the absence of
unequivocal hyperglycemia, diagnostic confirmation is generally
required.
C. The result indicates normal glucose tolerance.
D. The patient has hypoglycemia.
Answer: B
Rationale: A fasting plasma glucose of ≥126 mg/dL is in the diagnostic
range for diabetes, but when classic symptoms or unequivocal
hyperglycemia are absent, diagnosis generally requires confirmation
with repeat testing or another diagnostic test.
3. A patient with type 2 diabetes asks why hemoglobin A1C is useful.
Which response is best?
A. It measures glucose only during the previous 24 hours.
B. It measures insulin production directly.
C. It provides an estimate of average glycemia over approximately
the preceding 2–3 months.
D. It replaces all blood glucose monitoring.
Answer: C
Rationale: A1C reflects glycation of hemoglobin over the lifespan of
circulating red blood cells and provides an integrated estimate of
glycemia over approximately the previous 2–3 months. It does not
replace individualized glucose monitoring, particularly for people
using insulin or medications associated with hypoglycemia.
4. Which patient statement demonstrates correct understanding of
hypoglycemia?
A. “A glucose of 65 mg/dL is not concerning if I feel well.”
B. “I should take my long-acting insulin immediately whenever glucose
is low.”
2
,C. “If I am alert and able to swallow and my glucose is low, I should
promptly use a fast-acting carbohydrate source and recheck as
instructed.”
D. “I should exercise vigorously to raise my glucose.”
Answer: C
Rationale: Conscious patients who can safely swallow should treat
hypoglycemia promptly with fast-acting carbohydrate according to
their individualized treatment plan, followed by reassessment. Severe
hypoglycemia may require glucagon and emergency assistance.
5. A patient taking insulin becomes confused, diaphoretic, shaky, and
unable to safely swallow. What is the priority intervention?
A. Give oral juice immediately.
B. Administer additional insulin.
C. Encourage the patient to walk.
D. Administer glucagon according to the prescribed emergency plan
and obtain emergency assistance as appropriate.
Answer: D
Rationale: A person who cannot safely swallow is at risk for
aspiration. Oral carbohydrate should not be forced into the mouth.
Glucagon is an appropriate rescue treatment for severe hypoglycemia
when prescribed and available, with emergency assistance obtained
according to the circumstances.
6. Which symptom cluster is most consistent with diabetic
ketoacidosis (DKA)?
A. Bradycardia, hypothermia, and constipation
B. Polyuria, dehydration, abdominal symptoms, nausea/vomiting,
and deep or rapid respirations
C. Peripheral edema and severe hypertension only
D. Isolated weight gain
3
, Answer: B
Rationale: DKA is characterized by insulin deficiency, hyperglycemia
or sometimes less marked glucose elevation in selected circumstances,
ketone production, and metabolic acidosis. Clinical manifestations can
include dehydration, polyuria, nausea, vomiting, abdominal pain,
altered mental status, and deep/rapid respirations.
7. A patient taking an SGLT2 inhibitor reports nausea, vomiting,
abdominal discomfort, and rapid breathing despite a glucose level
of 185 mg/dL. What should the diabetes educator emphasize?
A. “DKA is impossible unless glucose exceeds 250 mg/dL.”
B. “Take another dose of the medication.”
C. “You may still have ketoacidosis despite the relatively modest
glucose level and require urgent medical evaluation.”
D. “Drink a sugary beverage and wait 24 hours.”
Answer: C
Rationale: SGLT2 inhibitor-associated DKA can occur with glucose
levels below 200 mg/dL, sometimes called euglycemic DKA. Patients
need education regarding symptoms, ketone assessment when
appropriate, sick-day management, hydration, and when to seek
urgent care. Current ADA guidance specifically highlights this risk.
8. Which statement about diabetes self-management education and
support (DSMES) is most appropriate?
A. It should occur only immediately after diagnosis.
B. It is unnecessary once a patient knows how to inject insulin.
C. It should be individualized and revisited as diabetes, treatment,
technology, life circumstances, and self-management needs change.
D. It should focus exclusively on carbohydrate counting.
Answer: C
