- A.
1.2 ml
- B.
10.2 ml
- C.
0.12 ml
- D.
2.4 ml
Correct Answer
B. 10.2 mlExplanation
To find the amount of concentrated vial needed to add to the IV bag, we can use the formula:
Amount of concentrated vial = (Desired dose / Concentration of vial) * Volume of IV bag
In this case, the desired dose is 45 mEq, the concentration of the vial is 4.4 mEq/ml, and the volume of the IV bag is 1000 ml.
Plugging in the values, we get:
Amount of concentrated vial = (45 mEq / 4.4 mEq/ml) * 1000 ml = 1022.73 ml
Since we have a 50 ml vial, we need to round up to the nearest whole number, giving us 1030 ml. However, since we only have 50 ml available, we can only add 50 ml of the concentrated vial to the IV bag. Therefore, the correct answer is 10.2 ml.Rate this question:

75 ml bottle of 500 mg/5 ml
- D.
100 ml bottle of 500 mg/5 ml
Correct Answer
D. 100 ml bottle of 500 mg/5 mlExplanation
The child's dose for cefadroxil is 30 mg/kg body weight once a day for 4 days. The child weighs 44 lbs, which is approximately 20 kg. Therefore, the child would need a total of 600 mg (30 mg/kg x 20 kg) of cefadroxil for the 4-day treatment period.
The 100 ml bottle of 500 mg/5 ml provides 500 mg of cefadroxil in every 5 ml. To calculate the amount of medication needed for 14 days, we can multiply the daily dose (600 mg) by the number of days (14) to get a total of 8,400 mg.
Since the 100 ml bottle provides 500 mg in every 5 ml, we can calculate the number of ml needed by dividing the total amount of medication needed (8,400 mg) by the amount of medication in every 5 ml (500 mg). This gives us 16.8 ml.
Therefore, the smallest bottle that will provide enough medication to last 14 days is the 100 ml bottle of 500 mg/5 ml.Rate this question:

- C.
4 tsp
- D.
5 tsp
Correct Answer
A. 1.25 tspExplanation
To find the number of teaspoons needed for the required dose, we can set up a proportion. Since the drug is available as 400 mg/5 ml, we can set up the proportion as 400 mg/5 ml = 500 mg/x tsp. Cross-multiplying gives us 400x = 5 * 500, which simplifies to 400x = 2500. Dividing both sides by 400 gives us x = 2500/400, which equals 6.25. Since there are 5 ml in 1 teaspoon, we divide 6.25 by 5 to get 1.25 tsp. Therefore, 1.25 tsp is needed for the required dose.Rate this question:

- A.
10 tabs
- B.
15 tabs
- C.
30 tabs
- D.
45 tabs

How many ounces of meds are needed to last 8 days if the dose of meds is one and one-half teaspoonsfuls four times a day?
- A.
4 oz
- B.
6 oz
- C.
8 oz
- D.
12 oz
Correct Answer
C. 8 ozExplanation
To calculate the number of ounces of meds needed to last 8 days, we need to determine the total amount of medication consumed per day and then multiply it by the number of days. The dose of meds is one and one-half teaspoonsfuls four times a day.
One and one-half teaspoonsfuls is equivalent to 3/2 teaspoonsfuls.
So, the total amount of meds consumed per day is 3/2 teaspoonsfuls * 4 times = 6 teaspoonsfuls.
Since 1 teaspoonful is approximately 0.17 ounces, the total amount of meds consumed per day is 6 * 0.17 ounces = 1.02 ounces.
Therefore, for 8 days, the total amount of meds needed is 1.02 ounces * 8 days = 8.16 ounces.
Rounding it up to the nearest whole number, we get 8 ounces.Rate this question:

The mixing instructions for a liq. anitibiotic call for 45 ml of water for constitution to make a 150 ml. susp. the final concentration of the susp. is 250 mg/5ml. What is the powder volume?
- A.
45 ml
- B.
90 ml
- C.
105 ml
- D.
205 ml
Correct Answer
C. 105 mlExplanation
The correct answer is 105 ml. This can be determined by using the final concentration of the suspension and the desired volume. The final concentration is given as 250 mg/5ml, which means that for every 5 ml of suspension, there is 250 mg of the antibiotic. The desired volume of the suspension is 150 ml. To find the powder volume, we can set up a proportion: (250 mg/5 ml) = (x mg/150 ml). Solving for x, we find that x = 105 ml, which is the powder volume needed.Rate this question:

How many ml of 70% alcohol should be mixed with 20 ml or 20% alcohol to prepare 50% alcohol?
- A.
20 ml
- B.
30 ml
- C.
40 ml
- D.
50 ml
Correct Answer
B. 30 mlExplanation
To prepare a 50% alcohol solution, we need to find the amount of 70% alcohol that needs to be mixed with 20 ml of 20% alcohol. Let's assume x ml of 70% alcohol is needed. The total volume of the mixture will be 20 ml + x ml.
The amount of alcohol in the 20% solution is 20 ml * 20% = 4 ml. The amount of alcohol in the 70% solution is x ml * 70% = 0.7x ml.
To find the overall concentration of the mixture, we can set up the equation: (4 ml + 0.7x ml) / (20 ml + x ml) = 50%.
Simplifying the equation, we get: (4 + 0.7x) / (20 + x) = 0.5.
Cross-multiplying, we get: 4 + 0.7x = 0.5(20 + x).
Simplifying further, we get: 4 + 0.7x = 10 + 0.5x.
Combining like terms, we get: 0.2x = 6.
Dividing both sides by 0.2, we get: x = 30 ml.
Therefore, 30 ml of 70% alcohol should be mixed with 20 ml of 20% alcohol to prepare a 50% alcohol solution.Rate this question:
