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 D
Explanation
A. Team members may be very good at time management but poor on job satisfaction is incorrect. While a laissez-faire leader may allow autonomy, it typically leads to a lack of direction and focus rather than improved time management. Job satisfaction can often be lower because team members may feel unsupported or unclear about expectations.
B. Team members experience disagreements among themselves is incorrect. Although lack of leadership can lead to some conflicts, the key characteristic of a laissez-faire leadership style is often lack of direction, not necessarily an increase in conflict. The absence of leadership can lead to confusion, but not always direct conflict among team members.
C. Productivity is high with low job satisfaction is incorrect. With a laissez-faire leadership style, productivity is often lower due to the lack of structure, guidance, and accountability. When people are not guided or supervised, their performance typically suffers.
D. The staff may be very knowledgeable but have lack of focus on the job at hand is correct. A laissez-faire leadership style involves little to no direction or supervision, allowing team members to make their own decisions. This can lead to knowledgeable staff, but without proper guidance or a strong focus on the tasks at hand. Lack of direction and focus often results in poor organizational performance and low motivation.
Correct Answer is B
Explanation
A. Polyphagia is incorrect. Polyphagia (excessive hunger) is typically associated with diabetes mellitus, not diabetes insipidus. In diabetes insipidus, the primary issue is excessive thirst and urination, rather than increased appetite.
B. Dehydration is correct. Diabetes insipidus causes the kidneys to excrete large volumes of dilute urine, leading to dehydration. Clients with this condition may experience excessive thirst (polydipsia) and urinate large amounts of water, leading to dehydration if fluid intake doesn't keep up with the loss.
C. Bradycardia is incorrect. Bradycardia (slow heart rate) is not a typical finding in diabetes insipidus. On the contrary, dehydration resulting from excessive urination could lead to tachycardia (increased heart rate) as a compensatory mechanism.
D. Hyperglycemia is incorrect. Hyperglycemia (high blood glucose) is characteristic of diabetes mellitus, not diabetes insipidus. In diabetes insipidus, blood glucose levels are typically normal since the condition does not involve insulin or glucose metabolism.
