Directions: Select the one best answer for each question. These original practice questions are based only on the uploaded
review PDF; they are not official exam items or a prediction of a lecturer’s exam.
1. Which effect should the nurse associate with thyroid-stimulating hormone (TSH)?
A. It initiates uterine contractions
B. It stimulates the thyroid gland to produce thyroid hormones
C. It lowers blood glucose by promoting cellular uptake
D. It stimulates the adrenal medulla to release epinephrine
✓ Correct answer: B. It stimulates the thyroid gland to produce thyroid hormones
Rationale: The source identifies TSH as stimulating the thyroid gland to produce thyroid hormones.
2. Which neuron fiber conducts impulses away from the cell body toward another neuron, muscle, or
gland?
A. An axon
B. A synaptic cleft
C. A dendrite
D. A receptor
✓ Correct answer: A. An axon
Rationale: The source states that axons conduct impulses away from the cell body and may deliver them to
neurons, muscles, or glands.
3. A neuron receives a stimulus through highly branched fibers that conduct impulses toward the cell
body. Which structures are these?
A. Axons
B. Tracts
C. Dendrites
D. Nodes
✓ Correct answer: C. Dendrites
Rationale: The review describes dendrites as branched fibers that conduct impulses toward the cell body and
may function as receptors.
4. A medication is prescribed to stimulate uterine contractions and milk ejection. Which hormone in the
source has both actions?
A. Melatonin
B. Prolactin
C. Oxytocin
D. Follicle-stimulating hormone
✓ Correct answer: C. Oxytocin
Rationale: The source identifies oxytocin as causing uterine muscle contraction and milk ejection from
mammary glands.
5. A decrease in blood oxygen supply prompts a kidney-produced hormone that stimulates red blood
cell production in bone marrow. Which hormone is this?
A. Insulin
B. Erythropoietin (EPO)
C. TSH
D. ANP
✓ Correct answer: B. Erythropoietin (EPO)
Rationale: The review notes that the kidneys produce EPO, which stimulates red blood cell production in
bone marrow; production increases when blood oxygen supply decreases.
, 6. During sympathetic activation, what pupil response is listed in the source?
A. Tear secretion
B. Constriction
C. No change in the pupil
D. Dilation
✓ Correct answer: D. Dilation
Rationale: The source’s autonomic effects table lists pupil dilation for the sympathetic system and constriction
for the parasympathetic system.
7. A patient’s pituitary activity changes after signals from the hypothalamus. Which hypothalamic signal
controls the release of anterior pituitary hormones?
A. Oxytocin from the mammary glands
B. ADH released from the posterior pituitary
C. Releasing hormones
D. ANP released by the atria
✓ Correct answer: C. Releasing hormones
Rationale: The review notes that hypothalamic releasing hormones control anterior pituitary hormone release
through a portal system.
8. Which hormone from the anterior pituitary stimulates milk production by mammary glands?
A. Prolactin (PRL)
B. Progesterone
C. Cortisol
D. Oxytocin
✓ Correct answer: A. Prolactin (PRL)
Rationale: The source distinguishes prolactin, which stimulates milk production, from oxytocin, which causes
milk ejection.
9. Which statement about cerebrospinal fluid (CSF) matches the source?
A. It carries visual impulses and is made by the retina
B. It produces myelin in peripheral nerves
C. It is released by the adrenal cortex during stress
D. It cushions nervous tissue and is manufactured by the choroid plexus in each ventricle
✓ Correct answer: D. It cushions nervous tissue and is manufactured by the choroid plexus in each
ventricle
Rationale: The source says CSF supports and cushions nervous tissue, carries nutrients and wastes, and is
manufactured by the choroid plexus in each ventricle.
10. A patient’s blood glucose is low. Which hormone stimulates the liver to release glucose?
A. Insulin
B. Prolactin
C. Glucagon
D. PTH
✓ Correct answer: C. Glucagon
Rationale: The review says pancreatic alpha-cell glucagon stimulates the liver to release glucose, increasing
blood glucose levels.
11. A pituitary hormone stimulates growth and hormonal activity of the adrenal cortex. Which hormone is
involved?
A. Prolactin (PRL)
B. Antidiuretic hormone (ADH)
C. Follicle-stimulating hormone (FSH)
D. Adrenocorticotropic hormone (ACTH)
✓ Correct answer: D. Adrenocorticotropic hormone (ACTH)
Rationale: The review lists ACTH as stimulating growth and hormonal activity of the adrenal cortex.
