Answer 16

feeding tubes deliver nutrition and medications directly into the intestines

Question 17

nasogastric/orogastric
naso-jejunal
gastrostomy/jejunostomy

Question 19

Describe a nasogastric/orogastric feeding tube.

Answer 19

inserted through the nasopharynx or mouth, ending in the stomach
used for short to medium term feeding (days to weeks)

Question 20

Describe a naso-jejunal feeding tube.

Answer 20

inserted through the nasopharynx, ending in the jejunum
require endoscopy or radiology to ensure the tube is in the correct position
short to medium use

Question 21

What are naso-jejunal feeding tubes prone to?

Answer 21

prone to blockage; evidence for using in drug administration is weaker

Question 22

Describe gastostomy/jejunostomy feeding tubes.

Answer 22

surgical placement into the stomach via the abdominal wall
long-term feeding (months to years)

Question 23

What is the pharmacists role with feeding tubes?

Answer 23

assess for interactions
-drug-formula/food interactions
assess absorption
-most drug are absorbed in GIT, does the tube reach there?
assess for drug-tube compatibility
-can the drug and/or formulation be given via tube?

Question 24

Why does it matter where the feeding tube ends in the GIT when administering drugs?

Answer 24

directly impacts overall exposure to the medication and consequently, effectiveness
-when medications go through a tube, the exit site of the tube is important to understand

Question 25

What are two main problems with drug-tube compatibility?

Answer 25

tube occlusion
drug adhesion

Question 26

What causes tube occlusion?

Answer 26

formula and/or medications

Question 27

What needs to be done if a tube cannot be unblocked?

Answer 27

must be replaced

Question 28

What is drug adhesion to a tube? What is the consequence?

Answer 28

drug interacts with the tube materials and binds
-results in decreased absorption of drug

Question 29

What are some solutions if absorption is an issue with a tube?

Answer 29

alternate route of admin
-suppository, transdermal, IV, small amounts orally?
therapeutic alternatives
-would a different drug be better absorbed?

-respiratory, urinary, GIT, skin losses

Question 33

How do you calculate the 4-2-1 Rule?

Answer 33

second 10 kg: 2ml/kg/hr
remaining kg: 1ml/kg/hr

Question 34

What is the pharmacists role with IV fluids?

Answer 34

electrolyte imbalance
-electrolyte dosage, administration safety
IV compatibility
-children usually have limited IV access
