NCLEX CRUSADE ACADEMY TEST - 12 ENDOCRINE DISORDERS NEXT GENERATION PRACTICE CLA

1. Which structure initiates endocrine signaling by releasing hormones such as CRH and TRH?. Thyroid gland. Hypothalamus. Adrenal cortex. Pancreas.

2. Which hormone is released from the anterior pituitary to stimulate cortisol production?. TSH. ACTH. ADH. Oxytocin.

3. Which adrenal hormone primarily regulates sodium reabsorption in the kidneys?. Cortisol. Epinephrine. Aldosterone. Insulin.

4. A deficiency of cortisol and aldosterone is characteristic of which disorder?. Cushing syndrome. Addison disease. Hyperthyroidism. Hypothyroidism.

5. A patient with Addison disease is most likely to demonstrate which electrolyte imbalance?. Hypernatremia and hypokalemia. Hyponatremia and hyperkalemia. Hypernatremia and hyperkalemia. Hypokalemia only.

6. Which clinical sign is commonly associated with Addison disease?. Moon face. Hyperpigmentation. Buffalo hump. Central obesity.

7. A nurse preparing emergency treatment for Addison disease should anticipate administration of: Levothyroxine. Hydrocortisone. Propranolol. Insulin.

8. Cushing syndrome results from excessive production of which hormone?. Insulin. Cortisol. Aldosterone. Thyroxine.

9. Which physical characteristic is associated with Cushing syndrome?. Weight loss. Moon face. Hypotension. Hypoglycemia.

10. A patient with Cushing syndrome may develop fragile skin because: Increased collagen synthesis occurs. Cortisol destroys collagen. Skin hydration increases. Immune activation strengthens tissue.

11. Which electrolyte imbalance is common in Cushing syndrome?. Hyponatremia. Hyperkalemia. Hypernatremia. Hypocalcemia.

12. Which endocrine disorder is associated with hypertension and weight gain?. Addison disease. Cushing syndrome. Hypothyroidism. Diabetes insipidus.

13. Which gland produces T3 and T4 hormones?. Pituitary gland. Thyroid gland. Adrenal cortex. Pancreas.

14. Which hormone stimulates the thyroid gland to release T3 and T4?. ACTH. TSH. ADH. Cortisol.

15. Hyperthyroidism causes an increase in which physiologic process?. Basal metabolic rate. Bone density. Blood clotting. Insulin secretion.

16. Which symptom is typical of hyperthyroidism?. Bradycardia. Weight gain. Tachycardia. Cold intolerance.

17. Which eye manifestation is associated with hyperthyroidism?. Ptosis. Exophthalmos. Miosis. Cataracts.

18. Propranolol is administered in hyperthyroidism primarily to: Reduce thyroid hormone production. Block sympathetic symptoms. Replace thyroid hormone. Stimulate metabolism.

19. Radioactive iodine therapy works by: Destroying thyroid tissue. Increasing thyroid hormone synthesis. Stimulating pituitary activity. Blocking ACTH.

20. Patients receiving radioactive iodine should avoid close contact with others because: They become immunocompromised. They emit radiation through body fluids. They develop infection risk. They exhale toxic gases.

21. Hypothyroidism results in which laboratory finding?. Low TSH, high T3/T4. High TSH, low T3/T4. High cortisol. Low ACTH.

22. Which symptom is most consistent with hypothyroidism?. Heat intolerance. Weight loss. Cold intolerance. Diarrhea.

23. Which cardiac finding is typical of hypothyroidism?. Tachycardia. Bradycardia. Hypertension. Arrhythmias.

24. The treatment for hypothyroidism typically includes: Cortisol replacement. Lifelong thyroid hormone therapy. Beta blockers. Diuretics.

25. Addisonian crisis is characterized by: Severe hyperglycemia. Profound hypovolemia and hypoglycemia. Excess thyroid hormone. Hypercalcemia.

26. Thyroid storm is a lifeIthreatening complication of: Hypothyroidism. Hyperthyroidism. Addison disease. Diabetes mellitus.

27. Myxedema coma is associated with: Severe hypothyroidism. Hyperthyroidism. Cushing syndrome. Addison disease.

28. Which GI symptom is common in hyperthyroidism?. Constipation. Diarrhea. Bowel obstruction. Ileus.

29. Which symptom is expected in hypothyroidism but not hyperthyroidism?. Tremors. Insomnia. Constipation. Tachycardia.

30. Endocrine disorders can become lifeIthreatening primarily because they affect: Bone structure. Hormonal regulation of vital systems. Skin pigmentation. Joint mobility.
