Question 1

Which of the following measures the weight or strength of a solid medication such as a tablet,powder,or topical preparation?

Accepted Answer

Gram is the unit of measurement for weight or strength of solid medications such as tablets, powders, or topical preparations. Liter is a unit of measurement for volume, and meter is a unit of measurement for length. Therefore, options A and C are incorrect.

Question 2

The most frequently used method for calculating pediatric doses relies on which of the following factors?

Accepted Answer

The most frequently used method for calculating pediatric doses relies on weight in kg, as it allows for dosing to be adjusted based on the individual child's body size. Age, absorption, and drug metabolism may also be factors in dosing, but they are typically taken into consideration in addition to weight. Therefore, D is the best choice as it is the most important factor for calculating doses in pediatrics.

Question 3

Starting at the top of a drug label,the drug's name is directly followed by what information?

Accepted Answer

The drug's name is directly followed by dosage and strength information on the label.

Question 4

One inch is equal to ____ cm.

Accepted Answer

2.5 cm = 1 inch.

Question 5

When calculating dosage based on body weight,which step is to calculate a single dose of the drug based on how frequently the medication is to be given throughout the day?

Accepted Answer

Step 3 involves calculating the single dose of the drug based on how frequently the medication is to be given throughout the day. Step 1 involves determining the patient's weight and Step 2 involves calculating the patient's weight in kilograms. Step 4 involves checking the calculated dosage against safe dosage ranges for the drug.

Question 6

What is the answer for the proportion 6:4 = 3:x?

Accepted Answer

Multiply the proportion by multiplying the two outer numbers and the two inner numbers; 6x = 12; divide each side by 6 to get 1x; x = 2.

Question 7

What is the ratio for the decimal 0.20?

Accepted Answer

20:100 reduced to its lowest form is 1:5.

Question 8

What is the first thing you should do if the dose of the supplied drug does not exactly match your calculation?

Accepted Answer

First, check your calculation for accuracy, and then check the stocked supply of the drug to make sure no other dosages are available. If the calculation is correct and no other dosages of the drug are available, you will have to round your answer to the nearest amount that matches the dose available. Make sure you check with the provider before administering a rounded dose of medication.

Question 9

Which of the following is true about a drug's brand name on a medication label?

Accepted Answer

Question 10

A physician prescribes administration of 100 mg of a drug.The drug label states that there are 150 mg per milliliter in a multidose vial that contains 5 mL.What is the available amount of the drug,according to the standard formula?

Accepted Answer

The available amount of the drug is asking for the amount of the drug in each milliliter of the vial. From the label, we know that there are 150 mg per milliliter, so the answer is D) 1 mL, as that contains the full amount of the drug prescribed by the physician (100 mg).

Question 11

The physician orders 7.5 mL of Cipro for a pediatric patient.How many teaspoons should the parent administer?

Accepted Answer

The conversion factor from mL to teaspoons is 1 mL = 0.2 tsp. Therefore, 7.5 mL x 0.2 tsp/mL = 1.5 tsp. The parent should administer 1.5 teaspoons.

Question 12

Which of the following fractions reflect the lowest possible term of 5/15?

Accepted Answer

To find the lowest possible term of a fraction, we need to simplify it as much as possible by dividing both the numerator and the denominator by their greatest common factor (GCF). In this case, the GCF of 5 and 15 is 5. So we divide both by 5: 
5/5 ÷ 15/5 = 1/3 
Therefore, the lowest possible term of 5/15 is 1/3, which is choice D.

Question 13

The physician prescribes 0.125 mg of Synthroid.On hand you have 0.25-mg tabs.What should you administer?

Accepted Answer

The physician has prescribed 0.125 mg of Synthroid, but the available tabs are 0.25 mg. Therefore, we need to administer half (1/2) of the 0.25-mg tab to get the prescribed dose of 0.125 mg. Therefore, the best choice is A) 1/2 tab.

Question 14

The correct dosage of medication may depend on which of the following factors?

Accepted Answer

The correct dosage of medication may depend on various factors such as the patient's age, weight, state of health, and other drugs being taken. Therefore, all the given options (A, B, and C) can play a significant role in determining the correct dosage of medication.

Question 17

The prefix milli in the metric system means

Accepted Answer

The prefix milli- in the metric system means one-thousandth or 0.001, which corresponds to option B and D. Therefore, the best choice is E.

Question 18

Federal law requires that all drug labels have a _________ that identifies that particular drug.

Accepted Answer

The National Drug Code (NDC) number is a unique 11-digit code that identifies a specific drug product. The generic and trade name, expiration date, and lot number are also required on drug labels, but do not fulfill the specific identification requirement of the NDC number.

Question 19

What must be done to divide fractions?

Accepted Answer

To divide fractions, you must invert the divisor (turn the second fraction upside down) and then multiply the numerators and denominators. This can be represented as: fraction 1 ÷ fraction 2 = fraction 1 x (1/fraction 2). Thus, the correct answer is E, because you must invert the divisor (B) and then multiply the numerators and denominators (C).

Question 20

Decimal numbers can be converted to percentages by?

Accepted Answer

To convert a decimal number to a percentage, we can either divide the number by 100 or move the decimal point two spaces to the right. Since both options are applicable, the correct answer is C (Both A and B).
