A nursing student correctly describes the process of osmosis
with which statement?
Water moves from an area of lower concentration of solutes to
an area of higher concentration.
Solutes move from an area of lower concentration to an area of
higher concentration.

A nursing student receives an order for plasma administration
and is unsure if this means a whole blood transfusion will be
used. The instructor gives which explanation?
Plasma can be separated from whole blood; so plasma will be
used.

A patient diagnosed with high blood pressure asks, "Why do I
have to monitor my salt intake?" Which explanation should the
nurse include in the response to this patient?
, "Sodium has a diuretic effect. You should increase the amount
you consume so that you will get rid of extra fluid and decrease
your blood pressure."
"Sodium helps to maintain blood pressure. Since your blood
pressure is high, you should decrease your sodium intake."
"Sodium affects the electrical activity within your heart.
Decreasing your sodium intake will allow your heart to pump
more effectively and decrease your blood pressure."
"Sodium is the main ingredient in salt; however, sodium does
not influence your blood pressure. I think the doctor told you to
monitor your potassium intake instead." Correct Answers
"Sodium helps to maintain blood pressure. Since your blood
pressure is high, you should decrease your sodium intake."
