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 nurse is assessing a client and notes that the client has developed swelling of the eyelids and lips after administration of a prescribed medication. The nurse interprets this finding as specifically indicating which of the following?
- A. Mild allergic reaction
- B. Anaphylactic shock
- C. Angioedema
- D. Drug idiosyncrasy
Correct Answer: C
Rationale: Angioedema is a type of allergic drug reaction manifested by the collection of fluid in the subcutaneous tissues, most commonly affecting the eyelids, lips, mouth, and throat. Allergic reactions can be manifested by a wide range of signs and symptoms such as itching, rashes, and hives. Anaphylactic shock is a serious allergic reaction that requires immediate medical attention. Drug idiosyncrasy describes any unusual or abnormal reaction to a drug, one that is different from the one normally expected.
Cecil and his wife are traveling to Southeast Asia on vacation and he has come into the clinic to review his medications. He is healthy with only mild hypertension that is well controlled. He asks about getting 'a shot' to prevent blood clots like his friend Ralph did before international travel. The correct response would be:
- A. Administer one dose of low-molecular weight heparin 24 hours before travel
- B. Prescribe one dose of warfarin to be taken the day of travel
- C. Consult with a hematologist regarding a treatment plan for Cecil
- D. Explain that Cecil is not at high risk of a blood clot and provide education about how to prevent blood clots while traveling
Correct Answer: D
Rationale: Cecil's low risk doesn't warrant prophylaxis; education on hydration and movement suffices. Heparin or warfarin is overkill without indication.
