There are different methods of transportation of fluids and other molecules through the body. Based on this information, what would be the most accurate description for the nurse to share about osmosis?
A) Movement of molecules from an area of higher concentration to an area of lower concentration
B) Most important mechanism by which nutrients and waste pass across the cell membrane
C) Water moves from a hypotonic solution to a hypertonic solution
D) Pressure exerted to start the flow of water across a membrane
C
Feedback:
Osmosis occurs when water moves from a hypotonic solution to a hypertonic solution. Diffusion is the random movement of molecules from an area of higher concentration to an area of lower concentration. Diffusion is the most important mechanism by which nutrients and waste pass across the cell membrane. Osmotic pressure refers to pressure exerted to stop the flow of water across a membrane.

A) Initially, check blood glucose levels frequently, such as every 4 to 6 hours, to evaluate for hyperglycemia. B) Be vigilant in monitoring the infusion rate, change the rate as necessary, and report any changes to the physician or nurse practitioner. C) If for any reason the TPN infusion is interrupted or stops, begin an infusion of a 10% saline at the same infusion rate as the TPN. D) Administer TPN continuously over an 8-hour period, or after initiation it may be given on a cyclic basis, such as over a 12-hour period during the night.
