Dose Calculation for Streptomycin Administration

What is the correct amount of streptomycin solution to administer and what size syringe should be used based on the doctor's order of 500 mg IM q12h and the concentration of the available vial? The amount of streptomycin solution that should be administered is 1.25 mL, which can be accurately measured using a 3 mL syringe. None of the options in the multiple choice question provided are correct. Explanation: In the question, the doctor ordered 500 mg of streptomycin every 12 hours, and the available vial you have contains 1 g (or, equivalently, 1000 mg) of streptomycin in 2.5 mL of solution. To figure out the amount of solution to administer, you need to set up a proportion using the information provided, so that: 500 mg / x mL = 1000 mg / 2.5 mL Cross multiplying and solving for x gives x = 1.25 mL, so you would give 1.25 mL of the solution. The size of the syringe you'd use should be one that can accurately accommodate this volume. Given the options in the question, a 3 mL syringe is a suitable choice, since it can accurately measure the required 1.25 mL volume. Hence, none of the choices in your multiple choice question are correct.

Administering medication accurately is crucial in healthcare settings to ensure patient safety and effective treatment. In this case, calculating the correct dosage of streptomycin solution is essential to follow the doctor's order and avoid medication errors.

The doctor's order specifies 500 mg of streptomycin to be given intramuscularly every 12 hours. However, the concentration of the available streptomycin vial is 1 gram per 2.5 milliliters of solution. This means that 1 gram is equivalent to 1000 mg. By setting up a proportion equation, we can determine the appropriate amount of solution to administer.

Using the formula:

500 mg / x mL = 1000 mg / 2.5 mL

We can calculate that x = 1.25 mL, which is the correct amount of streptomycin solution to give to the patient. It is important to be precise in preparing and administering the medication to ensure the patient receives the proper dosage.

When choosing the syringe for administration, it is essential to select one that can accurately measure the required volume of 1.25 mL. In this case, a 3 mL syringe is the most suitable option as it can provide the necessary precision in delivering the medication.

It is crucial for healthcare professionals to perform dose calculations accurately and use the appropriate equipment to ensure patient safety and the effectiveness of the treatment. Understanding the principles of dosage calculations and medication administration is essential in delivering quality healthcare services.
