Answer 13

Inulin

Question 14

Substance used in the determination of plasma volume

Answer 14

I-albumin 131 (or Evan’s blue dye)

Question 15

When calculating the volume of extracellular fluid when using inulin, what has to be taken into account?

Answer 15

The amount of inulin that is naturally secreted by the kidneys

Question 16

Substance used to determine the total body water?

Answer 16

Antipyrine (or deuterated water or titrate water)

Can rapidly permeate cell membranes. Distributes uniformly throughout the ECF and ICF compartments

Question 17

Complications associated in using tritiated isotope water in calculating total body water?

Ingestion of water

Dehydration

IV infusion

Large amount of fluid loss from GI tract

Abnormal amount of fluid loss from sweating or kidneys

Answer 19

Water loss

Na Retention

Question 20

ECF becomes hyposmotic by what ?

Answer 20

Water gain

Na Loss

Question 21

Neuropsychiatric disorders

Drugs

Pulmonary disease

Postoperative patient

Question 22

Acute symptoms with [Na] between 120 meq/L and 125 meq/L (plasma)

Answer 22

Nausea and malaise

This is hyponatremia

Question 23

Acute symptoms with [Na] (plasma) between 110meq/L and 120 meq/L ?

Answer 23

Headache and lethargy

This is hyponatremia

Seizures

Coma

Permanent neurologic deficits

Death

(Severe hyponatremia)

Question 25

Are there chronic symptoms with hyposmolarity (hyponatremia)

Answer 25

No.

There is brain osmotic adaptation.

Question 26

Explain brain osmotic adaptation

Answer 26

Cerebral swelling will increase the flow of brain ISF towards the CSF decreasing the amount of swelling

Solutes move out of brain cells decreasing the amount of brain cell swelling
