The nurse is talking with a group of nursing students who are doing clinical hours on the unit. A student asks if all intramuscular (IM) drugs are absorbed the same. What factor would the floor nurse tell the students to affect absorption of the IM administration of drugs?
- A. Perfusion of blood to the subcutaneous tissue
- B. Integrity of the mucous membranes
- C. Environmental temperature
- D. Blood flow to the gastrointestinal tract
Correct Answer: C
Rationale: A cold environmental temperature can cause blood vessels to vasoconstrict and decreases absorption or in a hot environment vasodilate and increase absorption of IM medications. Blood flow to the subcutaneous tissues interferes with subcutaneous injection and blood flow to the gastrointestinal (GI) tract causes alterations in absorption for oral medications. The condition of mucous membranes can interfere with sublingual (under the tongue) and buccal (in the cheek) administration of drugs.

- A. Schedule I drug
- B. Schedule II drug
- C. Schedule III drug
- D. Schedule IV drug
Correct Answer: B
Rationale: Narcotics such as morphine are considered schedule II drugs because of the high abuse potential with severe dependence liability. Schedule I drugs have high abuse potential and no accepted medical use. Schedule III drugs have a lesser abuse potential than schedule II drugs and an accepted medical use. Schedule IV drugs have low abuse potential and limited dependence liability.
