NR 507 EDAPT ENDOCRINE SYSTEM
EDAPT COMPLETE STUDY GUIDE
QUESTIONS AND VERIFIED ANSWERS
●● Match the mechanisms of hormonal release with their descriptions.
Answer: Humoral stimuli - The control of hormonal release in response
to changes in extracellular fluid levels or ion levels.
Hormonal stimuli - The release of hormones in response to hormones
released by other endocrine glands.
Neural stimuli - The release of hormones in response to neural
stimulation.
●● In hormone regulation, which statement best describes the negative
feedback loop?
Answer: A reaction that causes a decrease in function to help maintain
homeostasis.
●● Hormone levels are primarily controlled through __________
feedback loops, in which __________ levels of a hormone inhibit its
further release.
Answer: Negative
,Rising
●● During labor, __________ released from the posterior pituitary gland
is an example of a __________ feedback loop.
Answer: Oxytocin
Positive
●● Drag and drop each condition to match the related cause that is
associated with a hormone imbalance.
Answer: Excess growth hormone (GH) - Acromegaly
Excess cortisol and increased secretion of adrenocorticotropin hormone
(ACTH) - Cushing syndrome
Low levels of parathyroid hormone (PTH) - Hypoparathyroidism
Deficiency of cortisol and aldosterone - Addison's disease
Decline in thyroid hormone production - Hashimoto thyroiditis
●● Which external factors can affect hormone secretion in all systems?
Select all that apply.
Answer: Chemicals
,Stress
Sunlight
Pollution
●● Match each hormone below with the environmental factor that is
linked to alterations in hormonal regulation.
Answer: Thyroid - Radiation
Cortisol - Sleep schedule
Glucocorticoids - Arsenic
Estrogen - BPA Plastic
●● Select the findings that suggest an alteration in hormonal regulation
is occurring.
An individual is 38-weeks pregnant. They are having contractions 7-8
minutes apart. Their healthcare provider ordered lab tests revealing that
their blood sugar was high and androgen levels were high.
Answer: Contractions
Blood sugar was high
Androgen levels were high

laboring process?
Answer: Positive feedback loop
