Final answer:
The question asks for the correct administration of Cefazolin 500 mg in 50 mL NS over 30 minutes, which involves a medical order for the dilution of the antibiotic in a saline solution and the proper infusion rate for intravenous delivery.
Step-by-step explanation:
The question relates to the administration of a medication dosage and the required infusion time for a drug in a healthcare setting. Specifically, it pertains to calculating how fast the infusion of Cefazolin (an antibiotic) should be given to a patient.
The order is to administer 500 mg of Cefazolin in 50 mL of Normal Saline (NS) over 30 minutes.
Cefazolin is an antibiotic used to treat bacterial infections. The order given is a medical prescription specifying how the drug should be diluted and the rate at which it should be administered to the patient. The dilution instruction is to mix 500 mg of Cefazolin in 50 mL of Normal Saline (NS), an isotonic solution. The infusion time is set at 30 minutes, which dictates the speed of the drip rate for the intravenous (IV) infusion.
To calculate the drip rate (if using a manual IV set), healthcare providers may need to use the formula: (Total volume in mL/Total time in minutes) × Drop factor (in drops per mL), typically found on the IV tubing package. This calculation ensures the medication is delivered safely and at the correct rate, to achieve the desired therapeutic effect and avoid both underdosing and overdosing. For an infusion pump, the healthcare provider would simply program the pump to deliver the medication over the specified 30-minute period.
