NURS 8022 EXAM 4 ENDO PATHO |COMPLETE QUESTIONS WITH EXPERT
SOLUTIONS| 2026 LATEST UPDATED| A+
1. What are the mechanisms of hormonal alterations?: 1. Failure of feedback
systems 2.
Dysfunction of an endocrine gland 3. Altered hormone inactivation or
degradation 4. Ectopic hormone release 5.
Target cell dysfunction
2. What can cause failure of feedback systems in hormonal regulation?:
Failure to function properly or responding to inappropriate signals.
3. What are the consequences of dysfunction of an endocrine gland?: Inability
to
produce or obtain an adequate quantity of required hormone precursors,
inability to convert precursors to the active hormone, or
excessive/inadequate hormone production.
,4. What is ectopic hormone release?: Hormone production at non-endocrine
sites without feedback mechanisms.
5. What is hormone insensitivity?: Failure of the target cell to respond to its
hormone due to receptor-associated disorders.
6. What are some receptor-associated disorders that can lead to hormone
insensitivity?: Decrease in the number of receptors, impaired receptor
function, presence of antibodies against specific receptors, and unusual
expression of receptor function.
7. What are intracellular disorders related to target cell dysfunction?:
Inadequate
synthesis of a second messenger, failure to produce the anticipated
hormonal response, and abnormal response to the second messenger.
8. What is SIADH and what causes it?: Syndrome of inappropriate antidiuretic
hormone secretion, characterized by abnormally high levels of ADH, often
due to ectopic secretion, surgery, or certain cancers.
, 9. What are the clinical manifestations of SIADH?: Euvolemic hypotonic
hyponatremia, weight gain, headache, nausea/vomiting, confusion, and
potentially severe neurologic damage.
10. What sodium level indicates hyponatremia?: Sodium <135 mEq/L.
11. What is diabetes insipidus?: Insufficiency of ADH leading to polyuria and
polydipsia, with partial or total inability to concentrate urine.
12. What are the types of diabetes insipidus?: Neurogenic (central),
nephrogenic (renal), and dipsogenic/psychogenic.
13. What characterizes neurogenic diabetes insipidus?: Insufficient amounts
of ADH.
14. What characterizes nephrogenic diabetes insipidus?: Insensitivity of the
renal collecting tubules to ADH.
15 What is the urine output in diabetes insipidus?: 8 to 12 L/day, compared to
normal output of 1 to 2 L/day.
