Answer 12

-D5W
-normal saline
-LR

Question 13

what is special about D5W? what pts do we use with caution?

Answer 13

isotonic outside body, hypotonic inside body
cells swell
diabetes (increase BG), head trauma (altered LOC)

Question 14

what pts do we use NS with caution

Answer 14

renal or heart failure - fluid overload

Question 15

what pts do we use LR with caution

Answer 15

-CHF
-renal insufficiency

Question 16

hypotonic solutions cause cells to what? because?

Answer 16

swell, water floods into cell

Question 17

hypotonic solutions

Answer 17

-0.45% NS
-0.33% NS
-0.225% NS
-2.5% dextrose in water

Question 18

when would we give a hypotonic solution

Answer 18

hypernatremia

Question 19

caution with which pts for hypotonic solutions

Answer 19

head trauma
diabetes (D5W)
burns

Question 20

what happens to the cells with hypertonic solution? because?

Answer 20

cells shrink
water leaves the cells to ECF

Question 21

hypertonic solutions are normally given through what?

Answer 21

central line, less likely to infiltrate

Question 22

hypertonic solutions _____ risk of _____, stabilize _____, and regulates ________

Answer 22

decrease risk of edema
stabilize BP
regulate urine output

Question 26

what to watch for with colloids

Answer 26

-fluid overload - neck vein distention, increased BP, resp, distress
-monitor fluid balance (I&O, VS, HR, RR)
-monitor electrolytes

Question 27

signs of fluid overload

Answer 27

SOB, dyspnea, crackles

Question 28

causes of fluid volume deficit (hypovolemia)
