Answer to Question 1

A
Diffusion is the movement of a solute from an area of higher solute concentration to an area of lower solute concentration across a membrane.

Answer to Question 2

A
Feedback:
The nurse needs to apply a negative pressure between 100 and 140 mm Hg, depending on institutional policy, for adult clients when using a wall suction machine. When using a wall suction machine, 95 to 100 mm Hg of negative pressure is applied for children and 50 to 95 mm Hg of negative pressure is applied for infants.
