Endocrine Review of Systems Questions Questions
Question 1 of 5
Excessive eating despite plenty of glucose in the blood is called:
Correct Answer: D
Rationale: The correct answer is D: polyphagia. Polyphagia is the medical term for excessive eating despite adequate glucose levels in the blood, commonly seen in conditions like diabetes mellitus. This excessive hunger is due to the body's inability to use glucose effectively, leading to a constant feeling of hunger. A: Acidosis refers to an excess of acid in the blood, not related to excessive eating. B: Polyuria is excessive urination, not directly related to excessive eating. C: Polydipsia is excessive thirst, also not directly related to excessive eating. In summary, polyphagia is the correct term for excessive eating despite adequate glucose levels, while the other choices are unrelated to this specific symptom.
Question 2 of 5
The bones, kidneys, and intestine are target organs of this calcium-regulator hormone.
Correct Answer: B
Rationale: The correct answer is B: PTH. Parathyroid hormone (PTH) regulates calcium levels in the body by acting on bones, kidneys, and intestine. PTH stimulates release of calcium from bones, reabsorption of calcium in kidneys, and absorption of calcium in the intestine. T3 and T4 are thyroid hormones that do not directly regulate calcium levels. ACTH is adrenocorticotropic hormone that stimulates the adrenal glands. Oxytocin is a hormone involved in labor and lactation, not calcium regulation.
Question 3 of 5
Excess insulin is most apt to cause:
Correct Answer: B
Rationale: Excess insulin leads to increased glucose uptake by cells, causing a drop in blood sugar levels, resulting in hypoglycemia. This can lead to symptoms like confusion, sweating, and weakness. Ketosis (A) is caused by low insulin levels, hypertension (C) is not directly related to excess insulin, and diuresis (D) is more commonly associated with conditions like diabetes insipidus.
Question 4 of 5
Which of these is true of the endocrine system?
Correct Answer: D
Rationale: Step 1: The endocrine system secretes hormones that travel through the bloodstream to specific target cells. (Choice A) Step 2: These hormones regulate metabolic activities in the body. (Choice B) Step 3: The effects of hormonal actions can last for an extended period, leading to prolonged effects. (Choice C) Therefore, all the statements A, B, and C are true about the endocrine system, making choice D the correct answer. Other choices are incorrect as they do not encompass all aspects of the endocrine system's functions.
Question 5 of 5
The posterior pituitary stores and releases:
Correct Answer: C
Rationale: The correct answer is C: Oxytocin and antidiuretic hormone (ADH). The posterior pituitary stores and releases oxytocin and ADH, also known as vasopressin. Oxytocin is involved in uterine contractions and milk ejection, while ADH regulates water reabsorption in the kidneys. Choices A, B, and D are incorrect because the posterior pituitary does not store or release growth hormone or prolactin.
