Rationale:
Drugs must be water soluble in order to be excreted from the body as urine, feces, or sweat.
8.
False
Rationale:
Liver function does not correlate with the bodyโs ability to metabolize a drug and therefore would
not be helpful in determining elimination of the drug through the liver.
9.
True
Rationale:
Emetics are agents used to induce vomiting in the case of an overdose of ingested drugs.

SHORT ANSWER
1.
An endogenous chemical is one that is produced physiologically, while an exogenous
chemical is pharmacologically administered.
2.
Agonists are drugs that activate a specific receptor once they bind, whereas an antagonist
does not cause activation but results in very little or no response once it combines with a receptor
site. This action of the antagonist is responsible for lessening or blocking another drugโs effect.
3.
Patientโs with liver disease may experience greater than expected effects from a drug due
to an increase in the drugโs half-life. Because drugs are metabolized by the liver, if the liver is not
capable of breaking down or metabolizing the drug, it is able to remain in the body longer and
continue to elicit a response.
4.
The โdo not useโ list was designed to eliminate medical errors and misinterpretation
when using common abbreviations.
5.
Basic safeguards to prevent errors in medication administration include the six โrights.โ
They are described as: making sure you identify the right drug, administer the right dose to the
right patient at the right time via the right route, and complete the right documentatio n.

Rationale:
To convert from milliliters to liters, move the decimal point three places to the left.
2.
A
Page 94 of 150
Colbert_icp3_TestBank_questions.doc
Rationale:
To determine the dosage to administer, simply multiply 55 kg by 10 mg (55 kg ๏ด 10 mg = 550
mg).
3.
D
Rationale:
Using the factor-label method and example calculation 5 in the textbook, you can convert from
feet and inches to centimeters.
4.
B
Rationale:
Refer to example calculation 8 in the textbook to set up your calculation and solve for X.
5.
B
Rationale:
Using the factor-label method and example calculation 5 in the textbook, you can convert from
centimeters to inches.
6.
C
Rationale:
When you mix a drug with a diluent such as normal saline, the diluent does not decrease or
weaken the amount of drug given to the patient, whether you are using 2 ml or 5 ml. Only the
delivery time is increased.
7.
A
Rationale:
To determine the percentage strength of 20 mg in a 2 ml solution, you should recognize that it is
equivalent to 10 mg in 1 ml, or 1 g in 100 ml, which represents 1%. You can solve this by setting
up an equation with the known values and solving for X by cross-multiplying.
8.
A
Rationale:
The first step is to convert the patientโs weight to kilograms using the factor-label method (88 lb
= 40 kg). The next step is to determine the dosage to administer. If the order calls for 0.25 mg/kg,
simply multiply 40 kg by 0.25 mg (40 kg ๏ด 0.25 mg = 10 mg).
9.
B
Rationale:
Using example calculation 8 from the textbook, you can set up this problem with your known
values in the following way:
10 mg 4 mg
=
1 ml
X
10.
C
Rationale:
You convert the patientโs weight to kilograms by using the factor-label method, where 2.2 lb = 1
kg.
11.
D
Rationale:
You first convert the babyโs weight from grams to kilograms (.6 kg) and then use the factor-label
method to convert from kilograms to pounds, where 2.2 lb = 1 kg.
12.
B
Rationale:
Refer to Table 2โ2 to convert from liters to milliliters.
13.
D
Page 95 of 150
Colbert_icp3_TestBank_questions.doc
Rationale:
Using the factor-label method and example calculation 5 in the textbook, you can convert from
feet and inches to centimeters.
14.
D
Rationale:
A solution is a chemical and physical homogeneous mixture of two or more substances that
contains a solute and a solvent.
15.
B
Rationale:
A drug solution that consists of the active drug in solid (or powder) form mixed with a liquid
solvent is considered a weight/volume solution.
16.
D
Rationale:
The ratio becomes: X = .03 g or 30 mg
1g
Xg
=
100 ml 3 ml
17.
B
Rationale:
The active ingredient or drug in a solution is referred to as the solute.
18.
C
Rationale:
If 1.5 ml represents a 10% solution and the volume has been doubled to 3 ml, the percentage of
the solution is now half the original strength.
19.
A
Rationale:
A 10% solution represents 10 g/100 ml of solution, or 1 g per 10 ml of solution, or 0.1 g per 1 ml
of solution. If you know that there is 0.1 g per 1 ml, you can multiply this by 3 ml to find the
correct answer (0.3 g, or 300 mg).
20.
D
Rationale:
You first convert the babyโs weight from grams to kilograms. Then you determine how many
milliliters are needed if the required dosage is 3 ml per kilogram by multiplying 3 by the weight
in kg (3 ml ๏ด 1.5 kg).
21.
C
Rationale:
Knowing that 6% represents 6 g for every 100 ml, you can calculate the grams needed by using
example calculation 11 in the textbook.
22.
A
Rationale:
If you recognize the relationship between the dose on hand and the desired dose, you can
eliminate B and C immediately. You can then solve this problem by setting up an equation and
cross-multiplying to solve for X.
23.
B
Rationale:
You can solve this problem by setting up an equation and cross-multiplying to solve for X.
24.
A
Rationale:
6 g of active ingredient in 300 ml represents 2 g for every 100 ml, which is a 2% solution.
25.
B
Rationale:
16 gtt is equal to 1 ml.

True/False
1.
False
Rationale:
The Joint Commission recommends that a zero be placed before the decimal point (e.g., 0.1 mg)
but never after the decimal point by itself (e.g., 1 mg not 1.0 mg).
2.
True
Rationale:
The factor-label method, or fraction method, allows you to convert between the English and
metric systems.
3.
True
Rationale:
A solution contains an active drug, which is the solute dissolved in a solvent, such as sterile water
or normal saline.
4.
False
Rationale:
If a solute is a powder that is dissolved in a liquid, the resulting solution is termed a
weight/volume solution. Weight represents the weight or amount of solute, and volume represents
the total amount of solution.
5.
False
Rationale:
The nomogram used to determine body surface area (BSA) combines height and weight in a
single measurement to determine a patientโs overall body size. If a drug dosage requires a specific
number of units per patient weight in kilograms, the factor-label method should be used to
convert the patientโs weight from the English system to the metric system.
6.
True
Rationale:
The International System is also known as the metric system and is used in health care and by
drug manufacturers.
7.
False
Rationale:
To convert from milliliters to liters, the decimal point must be moved three places to the left.
8.
True
Rationale:
Solutes can be either solid particles such as powders or liquids.
9.
False
Rationale:
Weight/volume solutions represent the weight of the solute, which is a solid, dissolved in a liquid
solution.
10.
True
Rationale:
Using BSA to determine a patientโs overall size is appropriate, especially if the patient is not
within his or her ideal body weight due to disease or malnutrition.

SHORT ANSWER
Page 97 of 150
Colbert_icp3_TestBank_questions.doc
1.
When using measurements involving cubic centimeters, The Joint Commission
recommends using โmlโ for milliliter because 1 ml = 1 cc and cc can be misread in a number of
ways.
2.
Examples may include conversions used for length (e.g., 1 inch = 2.54 cm), weight (e.g.,
2.2 lb = 1 kg), or volume (e.g., 1.06 qt = 1 liter).
3.
If a solid solute is mixed with a solvent, the resulting solution is termed a weight/volume
(w/v) solution, where w represents the weight of the solute and v represents the total amount of
solution. If a liquid solute is mixed with a solvent, the resulting solution is termed a
volume/volume (v/v) solution, where the first v represents the volume of the solution and the
second v represents the total amount of solution.
4.
A drug strength can be expressed as a percent solution and as a ratio solution.
5.
You can use a proportion of the dose on hand related to the desired dose to set up an
equation and solve for the correct amount. Refer to Figure 2โ4, which illustrates the steps in the
equation.
