Q

How much water is lost in sweat

18
Q

how much water is lost insensibly (lung and skin)

19
Q

How much water is lost through urine?

20
Q

Fluid intake is regulated by

A

thirst center

21
Q

urin evolume is regulated by

22
Q

Thirst and ADH secreteion are controlled by centers in the hypothalamus, when are they stimulated?

A

increase in plasma osmolarity, reduction in plasma volume

23
Q

When is ADH secreted and when is angiotensin 2 secreted?

A

increase plasma osmolatiry –> ADH, decrease plasma volume –> angiotensin, but its also important to note that Angio2 also causes a relase in ADH :D

24
Q

List high risk groups of electrolyte imbalance?

A
– Children and old people.
– Surgical patients.
– Patients with pre-existing disease:
• Renal.
• Cardiovascular.
• Gastrointestinal.
25
abnormal fluid in interstitial spaces.
edema
26
State examples for Effectivevolumedepletion
edema, heart failuree
27
internal sequestration
ascities, ppleural effusion
28
symptoms of hypovolemia
– Thirst,posturaldizziness,weakness.
29
7% volume loss is considered to be
moderate
30
more abnormal skin turgor
hypernatremia dehydration
31
falsely normal skin turgor
hyponatremic dehyration
32
water intoxication can cause convulsion, coma and death, that can be presented in
hyponatremic dehyration
33
primary renal sodium retention
– Glomerulonephritis. | – Acuterenalfailure.
34
Hormone excess:
– Conn’ssyndrome(moreAldosteronesecretion). – Cushing’ssyndrome(HighlevelofCortisol). – SIADH(syndromeofinappropriateantidiuretichormone).
35
Reducedoncoticpressure
nephrotic syndrome
36
combined abnormality in starling forces
cirrhosis
37
LVF, RVF, constrictive pericarditis, | vena caval or portal vein obstruction are all examples offffff
increased hydrostatic venous pressure
38
``` Symptoms: – Weight gain. – Breathlessness. – Abdominal or ankle swelling. – Increased urinary output. • Signs: – Full, bounding pulse. – Hypertension. – RVF (oedema, increase JVP, enlarged liver) and LVF. – Peripheral oedema, pleural effusions and ascites. ```
hypervolemia
39
list 4 causes of edema
1. Increased capillary hydrostatic pressure. 2. Increased capillary membrane permeability. 3. Decreased capillary oncotic pressure. 4. Lymphatic obstruction.
40
Salt or water retention causes __________, list examples
increased hydrostatic pressure. – Congestiveheartfailure. – Renalfailure. – Pregnancy.
41
increased capillary permeability
– Inflammation. | – Immune responses. – Burns.
42
filaria, surgical removal of LN are all examples of
lymphatic obstruction
