Medical Surgical Endocrine Quiz Questions
Question 1 of 5
Which is TRUE:
Correct Answer: D
Rationale: Gastrin promotes mucosal growth; G cells (not TG) secrete gastrin, secretin family includes CCK and VIP, G_{17} is principal, and G_{34} has a longer half-life.
Question 2 of 5
The nurse is caring for an 80-year-old patient with a history of type 2 diabetes and hypothyroidism. The physician wants to evaluate the patient's blood glucose levels and orders a fructosamine assay. Which factor best explains why the physician chose this test over other blood glucose tests?
Correct Answer: A
Rationale: Fructosamine measures glycated serum proteins, reflecting glucose control over 2-3 weeks, shorter than the 2-3 months of hemoglobin A1c, making it ideal for recent monitoring, especially in conditions like hypothyroidism that may affect A1c reliability.
Question 3 of 5
Which corticoid counteracts the inflammatory response?
Correct Answer: B
Rationale: Cortisol is the corticoid that counteracts the inflammatory process. Thyroxine is secreted by the thyroid gland. Insulin is secreted by the beta cells of the pancreas. It is responsible for regulation of blood glucose levels. Norepinephrine is secreted by the adrenal medulla in response to stimulation from the sympathetic nervous system. It functions as a pressor (causing blood vessel constriction) hormone to maintain blood pressure.
Question 4 of 5
Most hormones travel from the gland where they were produced to the tissues and cells which they act upon:
Correct Answer: C
Rationale: Hormones are typically secreted into the bloodstream by endocrine glands and travel through it to reach their target tissues, making the bloodstream the primary mode of transport.
Question 5 of 5
The hypothalamus determines the secretion of hormones from the anterior lobe of the pituitary gland by means of releasing hormones | Thyroxine plays a key role in maintenance of body temperature and is secreted from the thyroid gland, which is located close to the larynx
Correct Answer: B
Rationale: The Assertion (A) is TRUE because the hypothalamus produces releasing hormones to regulate anterior pituitary hormone secretion. The Reason (R) is TRUE as thyroxine helps regulate body temperature and is secreted by the thyroid near the larynx. However, R does not explain A, as they address different mechanisms.
