Question 1
What is the Roman numeral representation of the number 45?
Correct Answer:
XLV
Explanation:
The Roman numeral representation of the number 45 is XLV. In Roman numerals, the letters represent specific values. The letter 'X' stands for 10, 'L' stands for 50, and 'V' stands for 5. To break it down for 45: - The numeral 'XL' translates to 40, which is derived from the fact that 'L' (50) is preceded by 'X' (10), indicating a subtraction (50 - 10). - Following that, 'V' adds 5 to the total. Thus, XL (40) plus V (5) equals 45, confirming that XLV is indeed the correct representation. The other choices do not accurately represent the number 45. For instance, XLI symbolizes 41, which is constructed from 'X' (10) + 'L' (50) - 'I' (1). LIV represents 54, as it stands for 'L' (50) - 'I' (1) + 'V' (5). Lastly, XLVI represents 46, totaling 'XL' (40) plus 'VI' (6). Therefore, only XLV properly corresponds to the number 45.
Question 2
What is the sum of 1/4 and 2/5?
Correct Answer:
13/20
Explanation:
To find the sum of two fractions, you first need to express them with a common denominator. The fractions given are 1/4 and 2/5. The denominators are 4 and 5. The least common multiple (LCM) of 4 and 5 is 20. Next, you will convert each fraction to have this common denominator of 20. For 1/4, you multiply both the numerator and the denominator by 5: 1/4 = (1 × 5) / (4 × 5) = 5/20. For 2/5, you multiply both the numerator and the denominator by 4: 2/5 = (2 × 4) / (5 × 4) = 8/20. Now that both fractions have the same denominator, you can add them together: 5/20 + 8/20 = (5 + 8) / 20 = 13/20. Thus, the correct answer is indeed 13/20, as it represents the combined value of 1/4 and 2/5 when expressed with a common denominator. This demonstrates the correct method for adding fractions, which involves finding a common
Question 3
If a solution has 25 grams of dextrose in 500ml, what is the percentage strength of the solution?
Correct Answer:
5
Explanation:
To determine the percentage strength of a solution, you can use the formula for calculating percentage concentration, which is: Percentage (%) = (Amount of solute in grams / Total volume of solution in milliliters) × 100 In this scenario, the amount of dextrose (the solute) is 25 grams and the total volume of the solution is 500 ml. Plugging in the values: Percentage (%) = (25 grams / 500 ml) × 100 Calculating this gives: Percentage (%) = (0.05) × 100 = 5% This means that 5% of the solution consists of dextrose, which is why this answer is the correct choice. The solution's strength reflects how much solute is present relative to the total volume, indicating a clear understanding of concentration in pharmacy practice.
Question 4
A 1:4 solution contains how many grams of solute in 80ml of solution?
Correct Answer:
16 grams
Explanation:
To determine how many grams of solute are in an 80 mL solution of a 1:4 ratio, first understand that a 1:4 solution means there is 1 part solute for every 4 parts of solution. In total, there are 1 part solute + 4 parts solvent = 5 parts total. To find the amount of solute in the 80 mL solution, you can first calculate what one part equals in terms of volume. Since there are 5 parts total, divide the total volume of the solution by the number of parts: 80 mL ÷ 5 = 16 mL per part. Since the ratio is 1 part solute, we know that the amount of solute is equivalent to 1 part: 1 part = 16 mL. Next, to find how many grams this corresponds to, remember that in the context of a solution, you'll need to convert this volume to grams, but since we are not provided the density of the solute, we can work directly with the concept that in this ratio the mass of the solute in grams is equivalent to the volume of the solution in mL when working with water and dilute solutions. Thus, the
Question 5
To prepare a 500mg dose of chlorpromazine using 25mg/mL stock solution, how many mL will be needed?
Correct Answer:
20
Explanation:
To determine how many milliliters of a 25 mg/mL stock solution are needed to prepare a 500 mg dose of chlorpromazine, you can use the formula: Volume (mL) = Desired Dose (mg) / Concentration (mg/mL) First, you need to plug in the values: Desired Dose = 500 mg Concentration = 25 mg/mL Now, performing the calculation: Volume (mL) = 500 mg / 25 mg/mL = 20 mL This means that to achieve a total of 500 mg of chlorpromazine, you will need 20 mL of the 25 mg/mL stock solution. This calculation directly aligns with the requirement of preparing an accurate dose for patient care, ensuring that the technician successfully understands how to convert stock solution concentrations into measurable volumes needed for medication preparation.
