NSG 532 Exam 2 - Comprehensive Practice Questions
180 Multiple Choice Questions with Answers and Rationales
Endocrine System (Questions 1-35)
1. What are the 3 functional anatomical elements of the endocrine system?
A) Hormones, enzymes, and neurotransmitters
B) Primary endocrine glands, accessory endocrinocytes, and hormones
C) Hypothalamus, pituitary, and target organs
D) Receptors, second messengers, and hormones
Answer: B) Primary endocrine glands, accessory endocrinocytes, and hormones
Rationale: The endocrine system consists of primary endocrine glands (e.g.,
thyroid, adrenal), accessory endocrinocytes found throughout body systems, and
,the hormones they produce. This tripartite structure enables comprehensive
physiological regulation .
2. Which statement correctly differentiates endocrine from exocrine glands?
A) Endocrine glands release hormones through ducts; exocrine glands are ductless
B) Endocrine glands are ductless and release hormones into the bloodstream;
exocrine glands release products through ducts onto body surfaces
C) Both types release hormones into the bloodstream
D) Exocrine glands only function in digestion
Answer: B) Endocrine glands are ductless and release hormones into the
bloodstream; exocrine glands release products through ducts onto body surfaces
Rationale: Endocrine glands are "closed" systems that release hormones directly
into the bloodstream. Exocrine glands are "open" systems that release products
through ducts onto body surfaces or into cavities .
,3. How is the endocrine system primarily controlled?
A) Only by the pituitary gland
B) By nerve impulses, neurotransmitters, and the hormones it produces
C) Exclusively through negative feedback
D) Through the autonomic nervous system only
Answer: B) By nerve impulses, neurotransmitters, and the hormones it produces
Rationale: The endocrine system receives input from multiple sources:
homeostatic changes in plasma biomolecules, other hormones, nerve impulses
and neurotransmitters, and immune responses through cytokines .
4. What is the major center of neuroendocrine integration?
A) Pineal gland and thalamus
, B) Hypothalamus and pituitary gland
C) Adrenal medulla and cortex
D) Thyroid and parathyroid
Answer: B) Hypothalamus and pituitary gland
Rationale: The hypothalamus and pituitary gland together form the primary
neuroendocrine integration center. The hypothalamus connects to the anterior
pituitary via vascular connections and to the posterior pituitary via neuronal
connections .
5. Which statement accurately describes peptide/protein hormones?
A) They are lipid-soluble and require carrier proteins
B) They are polar, hydrophilic, and lipid-insoluble
