Antidiuretic Hormone (ADH) - Correct Answers ✅secreted
to fix low fluid volume. Tells the kidneys to hang on to water.
Fluids conserved and fluid volume goes up. Used in
conjunction with the RAAS.
Thyroid-stimulating Hormone (TSH) - Correct Answers
✅produce release or store the 3 thyroid hormones.
thyroxine (T4) and triodothyronine (T3),
calcitonin - increase calcium movement from blood to bone
Adrenocorticotropic Hormone (ACTH)— - Correct Answers
✅
ADH Undersecretion - Correct Answers ✅DIABETES
INSIPUDUS - too much fluid being lost. you won't "hold onto"
water effectively --water will indiscriminately flow from the
peritubular capillaries of the kidneys into the tubules and
becomes very dilute urine.
Diabetes Insipidus - Correct Answers ✅Pass too much
"flavorless" Urine (very dilute)
think of the D as down or decreased ADH, Dieresis, body is
Dry.

Renal-Related under-secretion of ADH - Correct Answers
✅Sick kidneys have a decreased response to ADH.
CNS related Under-secretion of ADH - Correct Answers
✅Pituitary Tumor
Head Injury
Cerebral Edema & IICP (increased inter cranial pressure)
Polyuria - Correct Answers ✅Voiding huge amounts of
dilute urine.
S&S of ADH undersecertion - Correct Answers ✅void huge
amounts of dilute water Pulyuria - thirsty- blood compartment
has less water - concentration increases
Think fluid volume deficit = low preload - from tissue to blood
domino effect
Syndrome of Inappropriate Antidiuretic Hormone (SIADH) -
Correct Answers ✅Oversecretion of ADH
What can trigger SIADH? - Correct Answers ✅Ectopic -
small-cell bronchogenic cancer
Various Drugs - anesthetics - post-op

Exam Questions and Answers (Latest

Trauma to brain - tumor or injury - pressure that causes
pituitary to over-secrete
Oliguria - Correct Answers ✅body holding on to water int
he vascular space
Person has a low GFR, goes from normal 30ml/hr to 15ml/hr.
A person who is edemitous and has high preload - Correct
Answers ✅SIADH - too much fluid retained, fluid shifted to
the tissues.
Poor skin turgor, sunken eyes, dry mucous membranes -
Correct Answers ✅ADH
Iodide - Correct Answers ✅T3 & T4 hormones depend on
this for uptake from the blood
T3 & T4 act - Correct Answers ✅metabolic rate
caloric requirements
oxygen consumption
carbohydrate & lipid metabolism

Understand the Negative Feedback of Thyroid function -
Correct Answers ✅drop in levels of thyroid hormones (T3 &
T4) in the bloodstream causes pituitary stimulated which
increases its secretion of TSH thyroid stimulated to release
more T3 & T4. once balance is restored there is a suppress of
TSH secretion from pituitary.
Hyperthyroidism - Correct Answers ✅is the state of having
excess T3 & T4 production and release
Graves Disease - Correct Answers ✅an autoimmune
disorder in which autoantibodies attack/stimulate TSH
receptors on the thyroid.
the autoantibodies "mimick" TSH - results in thyroid secreting
more T3 & T4.
Graves Disease S&S - Correct Answers ✅In overdrive.
Hypermetabolic
Hyperthyroidism S&S - Correct Answers ✅PSYCH/CNS—
nervous, irritable, tremors, insomnia, emotionally labile,
sometimes psychosis (hallucinations, paranoia)
CARDIOVASCULAR—tachycardia, increased afterload,
sometimes HF due to increased heart workload
