c. home healthcare.
d. long-term care.
4. According to the most current Nationwide Inpatient Sample data, which statement concerning EN is true?
a. Most hospitalized patients receive only enteral formula through the tube.
b. About 25% of long-term care residents receive EN.
c. Long-term care residents with cognitive impairment are more likely to receive EN.
d. More than half a million hospitalized patients receive EN annually.
5. Nurses responding to this survey identified which of the following as the medication most frequently added directly to EN formula?
c. GI medications
6. Which factor doesn't influence the compatibility of a drug mixed with EN?
a. the drug's pH
b. the EN formula's fiber content
c. the drug's viscosity
d. the volume of water used to flush the tube
7. Before administering medication through an enteral tube, the nurse should first
a. flush the tube with tap water.
b. stop the feeding.
c. check for EN residue adhering to the lumen.
d. measure gastric residual volume.
8. For most adult patients, what's the minimum amount of water used to flush the tube before drug administration?
a. 10 mL
b. 15 mL
c. 20 mL
d. 30 mL
9. What's the primary reason for using sterile water instead of tap water for flushing?
a. Sterile water removes residue better than tap water.
b. Sterile water is easier to keep at the bedside.
c. Sterile water is more cost-effective.
d. Tap water is frequently contaminated.
10. What's the best practice when more than one drug is scheduled for administration at the same time via an enteral tube?
a. Give each drug separately.
b. Mix at least two liquid medications together.
c. Crush at least two immediate-release medications together.
d. Mix one immediate-release medication and one liquid medication together.
11. Based on results from this survey, what percentage of nurses mix medications for enteral administration at least some of the time?
12. Which type of oral tablet can be crushed and given via an EN tube?
13. To administer the contents of hard gelatin capsules via enteral tube,
a. dissolve the capsule in 15 mL of warm water.
b. grind the capsule into a fine powder and mix with sterile water.
c. open the capsule and mix powder with tap water.
d. open the capsule and mix powder with sterile water.
14. Which drug dosage form is classified as modified release?
b. enteric-coated tablet
d. compressed tablet
15. Crushing enteric-coated tablets increases the risk of all of the following except
a. inadequate dosing.
b. tube occlusion.

17. Why is it important to dilute liquid medications before administering via EN tube?
a. Dilution prevents medication delivery through the distal end of the feeding tube.
b. Dilution increases drug viscosity.
c. Dilution increases drug osmolality.
d. Dilution improves drug delivery.
18. Liquid medications with high osmolality
a. are less effective when diluted.
