A patient is prescribed 80 mg of Tramadol Hydrochloride injection. The stock dose is 50mg / 2 mL. What volume will you require?

To determine the volume of Tramadol Hydrochloride injection needed for an 80 mg dose, you can use the concentration of the stock solution.

The stock solution has a concentration of 50 mg in 2 mL, which can be expressed as:

\[ \text{Concentration} = \frac{50 \text{ mg}}{2 \text{ mL}} = 25 \text{ mg/mL} \]

Now, to find the volume (V) required for an 80 mg dose, use the formula:

\[ \text{Volume (mL)} = \frac{\text{Desired Dose (mg)}}{\text{Concentration (mg/mL)}} \]

Substituting the values:

\[ V = \frac{80 \text{ mg}}{25 \text{ mg/mL}} = 3.2 \text{ mL} \]

Therefore, you will require 3.2 mL of the Tramadol Hydrochloride injection to administer an 80 mg dose.

answer without the }./ , frac,[,},{,[

To calculate the volume of Tramadol Hydrochloride injection needed for an 80 mg dose, follow these steps:

1. Determine the concentration of the stock solution. The stock dose is 50 mg in 2 mL. This means the concentration is 25 mg per mL.

2. Use the formula to find the volume required. The formula is: Volume (mL) = Desired Dose (mg) / Concentration (mg/mL).

3. Substitute the values. For an 80 mg dose: Volume = 80 mg / 25 mg/mL.

4. Calculate the volume. Volume = 3.2 mL.

Therefore, you will need 3.2 mL of the Tramadol Hydrochloride injection to administer an 80 mg dose.

A laboratory technician measures 48 ml of urine sample in a 4-ounce beaker. How many more ml of urine are necessary to fill the beaker?

To determine how many more milliliters of urine are necessary to fill the 4-ounce beaker, we first need to convert ounces to milliliters.

1 ounce is approximately equal to 29.57 milliliters. Therefore, a 4-ounce beaker holds:

4 ounces × 29.57 mL/ounce = 118.28 mL

Now, we subtract the amount of urine already measured (48 mL) from the total capacity of the beaker:

118.28 mL - 48 mL = 70.28 mL

Therefore, 70.28 mL of urine is necessary to fill the beaker.

You fill a storage cabinet with 12 bottles of normal saline. Each bottle contains 1000 mL. How many ounces of this solution are in the storage cabinet?

To find out how many ounces of normal saline are in the storage cabinet, we first calculate the total volume in milliliters and then convert that to ounces.

1. Calculate the total volume in milliliters:

   • Each bottle contains 1000 mL.
   • There are 12 bottles.

   Total volume = 12 bottles × 1000 mL/bottle = 12000 mL

2. Convert milliliters to ounces:

   • 1 ounce is approximately equal to 29.57 mL.

   To convert milliliters to ounces, use the formula:

   Ounces = Total volume in mL / mL per ounce

   So:

   Ounces = 12000 mL / 29.57 mL/ounce ≈ 405.43 ounces

Therefore, the storage cabinet contains approximately 405.43 ounces of normal saline.

A patient is prescribed 6 mg of cough medication. The label on the prescription says there are 2 mg per 4 mL. How many teaspoons of cough medication does the patient need to take?

To determine how many teaspoons of cough medication the patient needs to take, follow these steps:

1. Calculate the total volume needed for the prescribed 6 mg dose. The medication has a concentration of 2 mg per 4 mL.

   First, find out how many mL are required for a 6 mg dose:

   • The concentration is 2 mg in 4 mL, which can be simplified to:

     2 mg / 4 mL = 0.5 mg/mL.

   To find out how many mL are needed for 6 mg:

   Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

   Volume = 6 mg / (2 mg/4 mL) = 6 mg / 0.5 mg/mL = 12 mL.

2. Convert mL to teaspoons. There are approximately 5 mL in a teaspoon.

   To convert mL to teaspoons:

   Teaspoons = Volume (mL) / mL per teaspoon

   Teaspoons = 12 mL / 5 mL/teaspoon = 2.4 teaspoons.

Therefore, the patient needs to take approximately 2.4 teaspoons of the cough medication.

A patient requires 80 milligrams of Risperidone. The stock dose is 40mg / 10mL. What volume is needed?

To calculate the volume needed for an 80 mg dose of Risperidone, we can use the information provided about the stock dose.

1. Determine the concentration of the stock solution: The stock dose is 40 mg in 10 mL, which gives us a concentration of:

   40 mg / 10 mL = 4 mg/mL

2. Use the formula to find the volume needed: We need to find the volume (V) for the desired 80 mg dose. The formula is:

   Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

   Substituting the values we have:

   Volume = 80 mg / 4 mg/mL

3. Calculate the volume:

   Volume = 20 mL

Therefore, you will need 20 mL of the Risperidone stock solution to administer an 80 mg dose.
