Question

Jim gave Ms. dry 1 liter of distilled water by IV

(the osmolarity of the RBC, the concentration of solute particles, is 300 mOsm/L)

Ms. dry plasma 3L, her RBC volume 2L

Dry got much worse (no duh, right?) after Jim's treatment so the resident was called some blood from the patients and centrifuged it. The denser RBC's were forced to the bottom Osnilor : .833x2 = 1-0 tube. The supernatant plasma was pink. The resident then decided to infuse a Nad solution patient (the RBC membrane is impermeable to NaCl). he patient's plasma pink? hu plasma is Pirin becauwc tho Ved olio Coll Yuptures 5. Had Jim given Ms. Dry a NaCl solution instead of water, he might have helped her. What concentration NaCl solution should he have administered to leave her RBC volume unaffected in percent solution? For this question you need to convert the desired mosm solution to a percent solution. a. What is the correct mOSM solution that Jim should have used? HOMOS b. How much NaCl (the solute) is that in a liter of solution in mosmol? C. Now convert the mosmol to mmole d. Now convert that to moles of NaCl e. How much does that amount of NaCl weigh?

Explanation / Answer

Answer:

Why was the patient's plasma pink?

5) What concentration of NaCl should he have administered to leave her RBC volume unaffected in percent solution?

a) What is the correct mOsM solution that Jim should have used?

b) How much NaCl (the solute) is that in a liter of solution in mOsmol?

c) Now convert the mOsmol to mmole

d) Now convert that to moles of NaCl

e) How much does that amount of NaCl weigh? MW NaCl = 58.4 g/mol

f) How many mL are in a L

g) If Jim added the answer to (e) to 1L of solution, how many grams would be found in 100ml of the solution?

h) Percent solution is the number of grams of solute in 100ml of solution. What is the percent solution that Jim should have mixed up?

6) Was the NaCl solution infused by the resident the same as the concentration Jim should have originally given Ms. Dry (from question 5).

a) More concentrated, same concentration or Less concentrated

b) Why - 3% saline is typically used to treat severe cases of hyponatremia (low sodium).
