Introduction
Case Study Discussion
A. During this lesson, students will learn about assessment and emergency
care for a patient whose condition may require administration of a
medication.
B. Case Study
1. Present The Dispatch and Upon Arrival information from the chapter.
2. Discuss with students how they would proceed.
II. Administering Medications
A. A medication is a drug or other substance used as a remedy for illness
B. A drug is a chemical substance used to treat or prevent a disease or
condition.
C. Pharmacology is the study of drugs.
1. When the correct dose of a medication is administered appropriately, the
patient’s condition may improve significantly.
2. When a medication is administered inappropriately, some drugs can
cause serious side effects and deterioration in the patient’s condition.
D. EMT’s responsibility
1. Administer medications under the direct order of a physician only.
2. Administer only medications identified in local protocols.
E. EMT’s role
1. Administration implies that the EMT will take all the steps necessary to
give the patient a medication.
2. Assisting means that the EMT will prepare the medication and then hand
it to the patient who will take the medication.

DETAILED LESSON PLAN 14

How will you know what medications a
patient needs?
 What are the safety precautions to
observe when giving medications?

B. Nitroglycerin
1. Nitroglycerin is a medication used to treat cardiac patients with diseases
of the coronary arteries.
2. This medication is a vasodilator, which dilates the blood vessels.
3. It decreases the demand for oxygen by the heart muscle and increases
the supply of oxygenated blood to the heart.
4. The major side effect of this medication is hypotension.
5. It should not be administered to patients taking other medications known
to lower blood pressure.
C. Epinephrine
1. Epinephrine is a drug used to treat patients suffering from anaphylaxis.
2. During an anaphylactic reaction, a patient’s blood vessels dilate, the
bronchioles constrict, and the capillaries leak fluid.
3. Epinephrine constricts the vessels, dilates the bronchioles, and
decreases capillary permeability.

DETAILED LESSON PLAN 14
Class Activity
Instead of lecturing on this section, assign
each of the drugs listed to a group of
students and provide them with several
resources in addition to their texts. Each
group should take about 15 minutes to
research their assigned drug, and then
present their findings to the rest of the
class. Be sure to emphasize key points and
fill in any gaps.
Knowledge Application
Give several examples of patient problems
(asthma, chest pain, anaphylactic reaction,
or poisoning) and ask students what drug
used by EMTs may be indicated for the
patient.
Discussion Questions

administering nitroglycerin to a patient
who has recently taken a drug for
erectile dysfunction?
