NUR 1142C: Fundamentals of Pharmacology for Nursing Care
Do not start working on this by yourself at home. It is intended for group work.
Following the class session you may need to complete unfinished work on your own.
Topic 2a: Medical Terminology - Drug Classifications
Activity: Identifying and Differentiating Pharmacologic and Therapeutic Classes
Look up the generic name of the drug in the index of the Davis Drug Guide. Once you
locate the page, look in the pink box to find the pharmacologic and therapeutic classes
listed and fill in what you can in columns 2 and 3. Then look up the general use of each
therapeutic class on pp. 1 – 79.

Questions to consider:
1. Does every medication belong to a specified pharmacologic class? Why or why not?
2. Does every medication belong to a specified therapeutic class? Why or why not?
3. Do any medications belong to more than one therapeutic class? Why or why not?
4. Does the name of the pharmacologic class of gentamicin give you any clue what it is
used for?
5. Does the name of the therapeutic class of metoprolol give you any clue what it is
used for?
6. Metoprolol and diltiazem belong to common therapeutic classes but they belong to
different pharmacologic classes. If you wanted or describe or explain each drug’s
pharmacologic class what information from the Drug Guide would be helpful?
7. Where could you look to find the general use of an antitussive?

Topic 2b: Medical Terminology - Drug Forms and Routes of Administration
Activity: Identifying Potential Dosage Forms and Routes of Administration
Using your Davis Drug Guide, work in groups of 2 or 3 to answer these problems.
Then compare your answers with your whole group once you have completed all the
problems.
1. A patient has been diagnosed with angina pectoris and will be prescribed
nitroglycerin upon discharge for use at home.
 Write down all the dosage forms this medication is supplied in.
 Next to the dosage form write down the route or routes this form may be given.
 Can you think of any reasons one dosage form or route would be preferred over
another?
2. Your patient is ordered the following drugs in tablet form but is having difficulty
swallowing them and asks to take them in applesauce.
 Identify the medications that may be crushed and/or also comes in a liquid form.
 Discuss when you think an action would require calling the physician for an
order.
Crushed or Liquid Form?
Need to Call Physician?
Lasix 40 mg po daily
Digoxin 0.25 mg po daily
Calan SR 120 mg po daily
Carafate 1 g twice daily
Plavix 75 mg daily
Aspirin 81 mg po daily

3. A patient is one day post-op from an appendectomy, was NPO (nothing by mouth)
for 24 hours and now is starting to take a clear liquid diet. He was receiving an antiinfective medication, cefazolin 1 g, mixed in a piggyback bag.
The medication first started as a powder and the
nurse needed to mix it up. After putting the
proper diluent into the vial the powder dissolved
completely.
Take a look at the two different vials and the one ampule provided in the group
materials. Discuss the following:
 What term would you use for the medication now in liquid form? It is now a
_________________________________. How does this form differ from a
suspension?
 Compare and contrast the properties of the vials and ampules and discuss the
similarities and differences.
 If the physician decides to change the cefazolin from the IV route to the oral route,
will the medication stay the same or need to be changed to a different yet similar
medication? Could the nurse do this independently without having to wait for a
physician’s order?
 If the IV stopped working and there was a need to give a dose of the medication
by the intramuscular route would the patient be able to take the same medication?
Could the nurse do this independently without having to wait for a physician’s
order?

Topic 2c: Medical Terminology - Systems of Measurement
Activity: Identifying Units of Measurement and Computing Necessary Conversions


Circle all the units of measurements on the labels the following two pages.
Write to the right or below the label
o the abbreviation
o the full name of the unit of measure
o identify it as metric system, apothecary system, or household system
o whether it is a weight or volume


Doctor orders cefazolin 0.5 g IM q 6 h. Does this match the unit of measure for
this medication or does it require a unit conversion?

Doctor orders digoxin 0.02 mg po daily. Does this match the unit of measure
for this medication or does it require a unit conversion?

The doctor orders ampicillin and it is transcribed onto the medication administration
record as pictured below. Finish timing the medication schedule using the 24-hour

Topic 2d: Medical Terminology - Medication Equipment
Activity: Selecting and Using Most Appropriate Medication Equipment
The following equations represent possible dosage calculation problems you might
encounter. There is no need to be concerned about the order or medication at this
time, let’s just deal with the numbers for now.
1. 10,000 divided by 5000 =
Look at both the 1 mL and the 3 mL syringes. Which one can you measure the
exact amount in. Draw up the correct amount of liquid into the syringe. Have
your partner check it.
2. 50 divided by 200 =
Look at both the 1 mL and the 3 mL syringes. Which one can you measure the
exact amount in. Draw up the correct amount of liquid into the syringe. Have
your partner check it.
3. 10 divided by 20 multiplied by 2 =
Look at both the 1 mL and the 3 mL syringes. Find the space you think is the
volume for your answer on both syringes. Can you measure the exact amount
on either syringe? Draw up the correct amount of liquid into the syringe. Have
your partner check it. Which syringe would you rather use to draw up this
amount? Why
4. 450 divided by 330 =
Look at the 3 mL syringe. Find the space you think is the volume for your
answer. Can you measure the exact amount on this syringe? Round the
number to a value equal to the number of decimal places possible with this
syringe.
5. 2 divided by 35 =
Look at the 1 mL syringe. Find the space you think is the volume for your
answer. Can you measure the exact amount on this syringe? Round the
number to a value equal to the number of decimal places possible with this
syringe.
6. Find the two insulin syringes provided in the group materials. Compare the
markings on both. What unit of measure is used. What is the maximum dose
that may be drawn up in each. Observe the 25 unit marking on both and discuss
observations with partner.
7. Look at the various larger syringes and medicine cups provided. Write the total
volume in each piece of equipment. Describe how many decimal places may be
used for accuracy.
