3- Explain the medical importance of tonicity. Think about dialysis and IVs. Since tonicity is only influenced by solutes that cannot cross the membrane but it can exert‚ Solutes will be able to freely cross the membrane and do not affect tonicity because they will always be in equal concentrations on both sides of the membrane. Also‚ water will flow from a hypotonic solution to hypertonic. 4- Explain the direction of osmosis and effects of tonicity (hypotonic‚ hypertonic‚ or isotonic) in

Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

DIFFUSION= The movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Atoms and small molecules can move across a cell membrane by diffusion. OSMOSIS= Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane.

Alarms have their advantages and disadvantages. However‚ we could not thrive in nursing without alarms because they save lives. Are they annoying at times‚ yes they do. In the ICU‚ alarms are never shut off or turned down; they are set specifically to the patients’ parameters. (Hebda & Czar‚ 2013‚ p. 14) stated that “Patient safety is a priority for the health systems‚ professionals‚ and consumers around the world.” In the scenario given regarding working in a sterile environment and having
