VNSG 1409 Endocrine Test PrepU
2025/2026 Exam Questions and Answers
| A+ Score Assured
Which gland was originally identified as the master gland? - 🧠ANSWER
✔✔Pituitary
Explanation: Originally, the pituitary was identified as the master gland, but
currently the hypothalamus is given this title because it is responsible for
coordinating the nervous and endocrine responses.
A client has been experiencing a decrease in serum calcium. After
diagnostics, the physician proposes the calcium level fluctuation is due to
,altered parathyroid function. What is the typical number of parathyroid
glands? - 🧠ANSWER ✔✔Four
Explanation: The parathyroid glands are four (some people have more than
four) small, bean-shaped bodies, each surrounded by a capsule of
connective tissue and embedded within the lateral lobes of the thyroid.
Which diagnostic test is done to determine a suspected pituitary tumor? -
🧠ANSWER ✔✔Computed Tomography
Explanation: CT or magnetic resonance imaging is used to diagnose the
presence and extent of pituitary tumors.
Parathyroid hormone (PTH) has which effects on the kidney? - 🧠ANSWER
✔✔Stimulation of calcium reabsorption and phosphate excretion
Explanation: PTH stimulates the kidneys to reabsorb calcium and excrete
phosphate and converts vitamin D to its active form, 1,25-dihydroxyvitamin
D. PTH doesn't have a role in the metabolism of vitamin E.
, The pharmacology instructor is diagramming the nervous and endocrine
systems. What organ would the instructor diagram as the connector
between the nervous and endocrine systems? - 🧠ANSWER
✔✔Hypothalamus
Explanation: The hypothalamus is the coordinating center for the nervous
and endocrine responses to internal and external stimuli. The pituitary,
thyroid, and parathyroid glands all play an important role in hormones, but
do not connect the nervous and endocrine systems.
The thyroid gland produces and secretes which of the following in direct
response to serum calcium levels? - 🧠ANSWER ✔✔Calcitonin
Explnation: Calcitonin is produced and secreted by the thyroid gland.
Aldosterone is an adrenocorticoid hormone that is released in response to
ACTH. Erythropoietin is released by the juxtaglomerular cells in the kidney
in response to decreased pressure or decreased oxygenation of the blood
flowing into the glomerulus. Insulin is produced by the pancreas in
response to varying blood glucose levels.
