FSCJ-NUR 1460 Alterations of Hormonal
Regulation exam with precise detailed
solutions

The hormonal disorders will either be described as - Correct answer ✔-hypo
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




-hyper



Two types of failure when it comes to hormonal disorders... - Correct answer ✔-feedback
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




mechanisms fail to function |||||| |||||| ||||||




-dysfunction of an endocrine gland d/t cancer, an autoimmune disease, etc |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




Cell surface receptor associated disorders occur mainly with - Correct answer ✔-water soluble
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




hormones like INSULIN because there has to be a connection with a receptor and fat-soluble
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




hormones can be diffused through the membrane |||||| |||||| |||||| |||||| |||||| ||||||




Cell surface receptor associated disorders lead to a DECREASE in - Correct answer ✔-the
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




number of receptors |||||| ||||||




-therefore there is defective hormone-receptor binding |||||| |||||| |||||| |||||| ||||||




Cell surface receptor associated disorders, instead of a problem with the number of receptors,
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




- Correct answer ✔-there can be impaired receptor function
|||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




-receptors become "insensitive" to the hormone even though the hormone can physically be
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




at the receptor
|||||| ||||||




**think of insulin resistant diabetes |||||| |||||| |||||| ||||||

,2


Cell surface receptor associated disorders can deal with ANTIBODIES - Correct answer ✔-these
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




antibodies either block receptors completely or mimic the action of the needed hormone
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




**autoimmune

-can be a positive or negative effect (neither are good)
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




Intracellular disorders have acquired defects in - Correct answer ✔-POST-receptor signaling |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




cascades

-INSIDE the target cell |||||| |||||| ||||||




Intracellular disorders: inadequate synthesis of a second messenger - Correct answer ✔-second |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




messengers are needed to transduce the hormonal signal into an intracellular event
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




Intracellular disorders: example of inadequate synthesis of a second messenger - Correct |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




answer ✔-inadequate synthesis of the second messenger cAMP so that the target cell fails to
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




express the usual hormonal effect |||||| |||||| |||||| ||||||




Intracellular disorders: may be faulty response to hormone-receptor binding - Correct answer |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




✔-water-soluble hormones ||||||




-there is no generation of a second messenger period
|||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




**this can deal with the receptors that are present within the cell, even within the nucleus**
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




Intracellular disorders: the cell can also (and thirdly), - Correct answer ✔-respond abnormally |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




to the second messenger
|||||| |||||| ||||||




In the posterior pituitary, neuro-secretory cells in - Correct answer ✔-the thalamus produce
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




oxytocin and ADH |||||| ||||||




-the axon endings secrete or transmit the hormones into the bloodstream
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||

, 3


SIADH stands for - Correct answer ✔-syndrome of inappropriate antidiuretic hormone
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




**affects posterior pituitary gland |||||| |||||| ||||||




Patients with SIADH have abnormally high - Correct answer ✔-ADH/vasopressin secretion
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




-leading to an increased number of aquaporin channels in the renal collecting ducts, retaining
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




water



What can cause SIADH? - Correct answer ✔-brain injury (closed head injury) or infection (can
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




be anything from a trauma to a stroke to meningitis)
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




-ectopically produced ADH associated with a cancer |||||| |||||| |||||| |||||| |||||| ||||||




Ectotopically means - Correct answer ✔-somewhere else in the body |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




Paraneoplastic syndrome - Correct answer ✔ |||||| |||||| |||||| |||||| ||||||




Small cell lung CA - Correct answer ✔-cancer cells can perform unlike they should
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




-these cells can secrete high amounts of ADH
|||||| |||||| |||||| |||||| |||||| |||||| ||||||




With SIADH, there is water intoxication - Correct answer ✔-in the blood
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




-d/t enhanced renal water retention
|||||| |||||| |||||| ||||||




With SIADH, there is concentrated urine - Correct answer ✔-increased specific gravity, above
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




1.030

-urine will be very dark, not a lot (oliguria)
|||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||




With SIADH, the patient will have low serum osmolarity, which means - Correct answer ✔-
|||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| |||||| ||||||
