Question 18

Contents of L of 0.9% NaCl

Answer 18

A litre bag of 0.9%NACL

Each 1000ml contains NACL 9grams

Approximately 150mmols of Na and Cl per 1000ml

pH range 4.0-7.0

Approximate osmolality 300mOsm (taken from the product information)

Question 19

1 litre of 5% dextrose given intravenously would distribute predominantly to?

Answer 19

intracellular compartment

A 5% dextrose solution is similar to the infusion of pure water, and water distributes itself evenly throughout the body spaces. Therefore, most will go to the intracellular fluid (ICF) due to its percentage.

Question 20

Define osmolarity

Answer 20

Osmolarity is the number of osmoles per liter of solution.

Question 21

Define osmolality

Answer 21

Osmolality is the number of osmoles per kilogram of solvent.
