1. Which hormone is primarily responsible for lowering blood
glucose levels?
A. Cortisol
B. Glucagon
C. Insulin
D. Epinephrine
Answer: C. Insulin
Rationale: Insulin is produced by the beta cells of the pancreas and is
responsible for lowering blood glucose levels by facilitating the
movement of glucose into cells for energy or storage. Glucagon,
cortisol, and epinephrine increase blood glucose levels.
2. A nurse is caring for a patient with diabetes insipidus. Which
symptom should the nurse expect?
A. Weight gain
B. Excessive urination
C. Bradycardia
D. Hyperglycemia
Answer: B. Excessive urination
,Rationale: Diabetes insipidus is characterized by a deficiency of
antidiuretic hormone (ADH), leading to excessive urination and thirst.
Patients may also experience dehydration and electrolyte imbalances.
3. Which assessment finding is most commonly associated with
hyperthyroidism?
A. Cold intolerance
B. Weight gain
C. Bradycardia
D. Heat intolerance
Answer: D. Heat intolerance
Rationale: Hyperthyroidism increases the metabolic rate, causing
symptoms such as heat intolerance, weight loss, tachycardia, anxiety,
and excessive sweating.
4. A patient with hypothyroidism is likely to exhibit which
symptom?
A. Tachycardia
B. Exophthalmos
C. Fatigue
D. Diarrhea
Answer: C. Fatigue
Rationale: Hypothyroidism slows metabolic processes, leading to
fatigue, cold intolerance, weight gain, constipation, and dry skin.
5. Which laboratory value is most important to monitor in a
patient with diabetes mellitus?
A. Hemoglobin
B. Blood glucose
,C. White blood cell count
D. Platelet count
Answer: B. Blood glucose
Rationale: Blood glucose monitoring is essential in diabetes
management because it helps assess glycemic control and guides
treatment decisions.
6. Which hormone is secreted by the adrenal medulla?
A. Aldosterone
B. Cortisol
C. Epinephrine
D. Insulin
Answer: C. Epinephrine
Rationale: The adrenal medulla secretes epinephrine and
norepinephrine, which are involved in the fight-or-flight response.
7. A patient with Addison’s disease is at risk for which electrolyte
imbalance?
A. Hypernatremia
B. Hypokalemia
C. Hyperkalemia
D. Hypercalcemia
Answer: C. Hyperkalemia
Rationale: Addison’s disease involves adrenal insufficiency and
decreased aldosterone production, resulting in sodium loss and
potassium retention.
8. Which clinical manifestation is expected in Cushing’s
syndrome?
, A. Weight loss
B. Moon face
C. Hypoglycemia
D. Bronze skin pigmentation
Answer: B. Moon face
Rationale: Cushing’s syndrome results from excess cortisol production
and commonly presents with moon face, truncal obesity, buffalo
hump, and hypertension.
9. Which gland is known as the “master gland”?
A. Thyroid gland
B. Adrenal gland
C. Pituitary gland
D. Pineal gland
Answer: C. Pituitary gland
Rationale: The pituitary gland regulates many endocrine functions by
controlling other endocrine glands through hormone secretion.
10. A nurse is teaching a patient about insulin
administration. Which site provides the fastest absorption?
A. Abdomen
B. Thigh
C. Buttocks
D. Upper arm
Answer: A. Abdomen
Rationale: Insulin injected into the abdomen is absorbed more rapidly
due to greater blood flow compared to other injection sites.
