NCLEX CRUSADE ACADEMY TEST - 3 FUNCTIONS OF ENDOCRINE GLANDS

1. The primary role of the endocrine system is to: Provide structural support. Regulate body functions through hormones. Produce antibodies. Control voluntary muscle movement.

2. Hormones are best described as: Electrical impulses. Chemical messengers released into blood. Structural proteins. Immune cells.

3. The pituitary gland is known as the master gland because it: Produces digestive enzymes. Regulates other endocrine glands. Controls respiration. Produces insulin.

4. The thyroid gland primarily regulates: Blood clotting. Metabolism. Calcium storage. Oxygen transport.

5. Parathyroid hormone (PTH) primarily affects: Blood glucose. Calcium and phosphorus levels. Blood pressure. Oxygen levels.

6. An increase in parathyroid hormone results in: Decreased calcium. Increased calcium. Decreased phosphorus. Both B and C.

7. Hyposecretion of growth hormone during childhood results in: Acromegaly. Dwarfism. Gigantism. Hyperthyroidism.

8. Hypersecretion of growth hormone during adulthood causes: Gigantism. Acromegaly. Dwarfism. Hypocalcemia.

9. The thyroid hormone primarily influences: Bone density. Metabolic rate. Blood clotting. Oxygen saturation.

10. Hypothyroidism commonly causes: Heat intolerance. Weight loss. Cold intolerance. Tachycardia.

11. Hyperthyroidism commonly causes: Weight gain. Cold intolerance. Heat intolerance. Bradycardia.

12. Thyroid storm is characterized by: Hypothermia. Severe hypermetabolic state. Low blood pressure. Hypoglycemia.

13. Myxedema coma is a complication of: Hyperthyroidism. Hypothyroidism. Diabetes. Hypercalcemia.

14. A hallmark sign of hypocalcemia is: Muscle weakness. Facial twitching (Chvostek sign). Hypertension. Polyuria.

15. Trousseaus sign indicates: Hypoglycemia. Carpal spasm due to hypocalcemia. Hypercalcemia. Hypotension.

16. The endocrine system differs from the nervous system because endocrine signals: Travel faster. Travel through blood. Are electrical. Act only locally.

17. Negative feedback in endocrine regulation means: Hormone production increases continuously. Hormone production stops when levels are adequate. Hormones destroy target organs. Hormones act randomly.

18. The endocrine gland responsible for calcium balance is: Thyroid. Pituitary. Parathyroid. Pancreas.

19. Which endocrine gland directly affects metabolic rate?. Thyroid gland. Pituitary gland. Pancreas. Adrenal gland.

20. Hormones exert their effects by: Destroying cells. Binding to receptors on target cells. Blocking blood flow. Changing oxygen levels.

21. Endocrine disorders may result from: Hormone deficiency. Hormone excess. Receptor problems. All of the above.

22. Which gland controls metabolism and heart rate?. Pituitary. Thyroid. Parathyroid. Adrenal medulla.

23. Which hormone imbalance may lead to gigantism?. Thyroid hormone. Growth hormone. Insulin. Cortisol.

24. The endocrine system maintains: Muscle contraction. Homeostasis. Bone structure. Sensory perception.

25. A key NCLEX principle when treating endocrine emergencies is: Treat laboratory values only. Treat the patient condition first. Ignore symptoms. Focus only on monitors.
