Question 1

You receive an order for 16 gtt of Mucomyst.How many milliliters of drug would you be administering to the patient?

Accepted Answer

The standard drop factor for most medications is 20 gtt/ml. Therefore, to convert 16 gtt to ml, you divide by the drop factor: 16 gtt / 20 gtt/ml = 0.8 ml. However, since none of the options exactly match 0.8 ml, the closest option and the standard rounding for medication administration would be 1 ml.

Question 2

Weight is measured as ____________ or ________________ in the metric system.

Accepted Answer

The answer of Weight is measured as ____________ or ________________...

Question 3

The United States Customary System of Measurement is based on the _______________.

Accepted Answer

The answer of The United States Customary System of Measurement...

Question 4

A solute can either be a liquid or a solid that is dissolved in a liquid.

Accepted Answer

A solute can be either a liquid or a solid that is dissolved in a liquid.

Question 5

The use of body surface area (BSA)is an appropriate method to determine a patient's overall size.

Accepted Answer

BSA takes into account both height and weight of a person to provide a more accurate measurement of their overall size, which can be important for dosing medications or determining radiation doses for medical procedures.

Question 6

Converting a measure from milliliters to liters is accomplished by moving the decimal point three places to the right.

Accepted Answer

Converting a measure from milliliters to liters is accomplished by moving the decimal point three places to the left, not right. For example, 1000 milliliters is equal to 1 liter.

Question 7

A liquid or solid that is dissolved in a solution is known as a ________________.

Accepted Answer

The answer of A liquid or solid that is dissolved...

Question 8

Normal saline in solution with albuterol is known as the solvent.

Accepted Answer

In a solution, the solvent is the component that dissolves the solute. Normal saline acts as the solvent for albuterol, which is the solute.

Question 9

Terbutaline sulfate is available as 1 mg/1 ml in an ampule.How many milliliters are needed to administer a 0.75 dose?

Accepted Answer

If 1 ml contains 1 mg of terbutaline sulfate, then 0.75 mg of terbutaline sulfate is needed for the dose. 
To find the volume of the solution needed, we can set up a proportion:

1 ml / 1 mg = x ml / 0.75 mg

Solving for x, we get:

x = 0.75 ml

Therefore, 0.75 ml of terbutaline sulfate solution is needed to administer a 0.75 dose.

Question 10

When calculating drug dosages based on a patient's weight in kilograms,a respiratory therapist can use the BSA nomogram to convert from pounds to kilograms.

Accepted Answer

The BSA (Body Surface Area) nomogram is used to estimate a person's body surface area, not to convert pounds to kilograms. To convert pounds to kilograms, you divide the weight in pounds by 2.2046.

Question 11

The metric unit of measurement for length is ________________,and the metric measurement for volume is ________________.

Accepted Answer

The answer of The metric unit of measurement for length...

Question 12

What strength of drug would be administered if 6 g of active ingredient is reconstituted with sterile water to a total volume of 300 ml?

Accepted Answer

Strength of drug = (Weight of active ingredient / Total volume) x 100= (6 g / 300 ml) x 100= 2%

Question 13

A weight/volume solution is representative of the amount of liquid solute in a volume of solution.

Accepted Answer

A weight/volume solution actually represents the amount of a solid solute in a given volume of solution, typically expressed as a percentage.

Question 14

The International System is the system of measure used in health care.

Accepted Answer

The International System (also known as the SI system) is the standard system of measurement used in health care, as well as many other fields such as science and engineering. It includes units of measurement such as meters, kilograms, and seconds, and is designed to be universally understood and applied.

Question 15

The Joint Commission recommends that a zero always be placed after the decimal point when referring to drug dosage.

Accepted Answer

The Joint Commission recommends that a zero never be placed after the decimal point for drug dosages to prevent overdose; for example, 5 mg, not 5.0 mg, to avoid confusion with 50.

Question 16

Promazine comes in a 550-mg/10-ml liquid solution.How many milliliters are needed to give a 200-mg dose?

Accepted Answer

To calculate the amount of solution needed for a 200-mg dose, use the ratio: 550 mg / 10 ml = 200 mg / X ml. Solving for X gives X = (200 mg * 10 ml) / 550 mg = 3.636... ml, which rounds to 3.6 ml.

Question 17

When a solute is being dissolved in a powder,the solution is termed a volume/volume solution.

Accepted Answer

When a solute is being dissolved in a powder, the solution is not referred to as a volume/volume solution. A volume/volume solution refers to a solution where the solute is dissolved in a liquid solvent, and the concentration of the solute is expressed as the volume of the solute per volume of the solution.

Question 18

If a drug contains 6% active ingredient,how many grams of the active ingredient would you need in a 30-ml dose?

Accepted Answer

We know that the drug contains 6% active ingredient. This means that in every 100 ml of the drug, there are 6 grams of active ingredient.

To find out how many grams of active ingredient there are in a 30-ml dose, we can use a proportion:

6 g / 100 ml = x / 30 ml

where x is the amount of active ingredient in a 30-ml dose.

We can solve for x by cross-multiplying:

100 ml * x = 6 g * 30 ml

100 ml * x = 180 g*ml

x = 1.8 g

Therefore, the amount of active ingredient in a 30-ml dose is 1.8 g, which is option C.

Question 19

The method used to convert between the English and metric systems is referred to as the factor-label method.

Accepted Answer

The factor-label method, also known as dimensional analysis, is commonly used to convert between different units of measurement including the English and metric systems.

Question 20

The metric system of measurement is based on the __________________.

Accepted Answer

The answer of The metric system of measurement is based...
