Which hormone is secreted by the anterior pituitary gland and stimulates or controls the client's growth?
Luteinizing hormone (LH)
Thyroid-stimulating hormone (TSH)
Adrenocorticotropic hormone (ACTH)
Growth hormone (GH)
The Correct Answer is D
A. Luteinizing hormone (LH) is incorrect. LH is involved in regulating the reproductive system by triggering ovulation in females and stimulating testosterone production in males, but it does not primarily influence growth.
B. Thyroid-stimulating hormone (TSH) is incorrect. TSH stimulates the thyroid gland to release thyroid hormones, which regulate metabolism, but TSH is not the primary hormone responsible for controlling physical growth.
C. Adrenocorticotropic hormone (ACTH) is incorrect. ACTH stimulates the adrenal cortex to produce cortisol and other glucocorticoids, which help the body respond to stress but do not directly stimulate growth.
D. Growth hormone (GH) is correct. GH, also known as somatotropin, is secreted by the anterior pituitary and directly stimulates growth and development, particularly in bones and muscles, by promoting protein synthesis and increasing fat metabolism.

Correct Answer is A
Explanation
A. Monitor blood pressure closely for fluctuations is correct. After an adrenalectomy for pheochromocytoma, it is critical to closely monitor the client's blood pressure. Pheochromocytomas are tumors of the adrenal glands that cause excessive production of catecholamines (like epinephrine and norepinephrine), leading to severe hypertension. Postoperatively, the sudden removal of the tumor may cause blood pressure fluctuations, including hypotension after the excess catecholamines are no longer being produced. Monitoring blood pressure is key to detecting complications like hypotension or hypertensive crises early.
B. Check the client's urine output every hour is incorrect. While urine output is important to monitor in general postoperative care, it is not the priority in this case. The more immediate concern following adrenalectomy for pheochromocytoma is blood pressure control and hemodynamic stability, not just urine output.
C. Evaluate the client's pain level using a numeric scale is incorrect. While managing pain is essential, the priority assessment postoperatively for this particular procedure is to monitor for hemodynamic changes, particularly due to the risk of fluctuating blood pressure. Pain can be managed after addressing the primary concerns.
D. Assess the surgical site for signs of infection is incorrect. While infection is a concern for any postoperative patient, the most immediate risk after adrenalectomy for pheochromocytoma is hemodynamic instability due to catecholamine imbalance. Monitoring blood pressure takes precedence over checking for infection in the early postoperative period.
Correct Answer is ["25.0"]
Explanation
Total volume to infuse = 1000 mL
Total time = 8 hours × 60 minutes = 480 minutes
Drop factor = 12 gtts/mL
Multiply volume by drop factor: 1000 × 12 = 12,000
Divide result by time in minutes: 12,000 ÷ 480 = 25
Answer: 25 gtts/min
