Chapter 18: Problem 47

Order: Dexamethasone sodium phosphate \(5 \mathrm{mg}\) IV q12h.

Short Answer

Expert verified
Administer 5 mg of Dexamethasone sodium phosphate intravenously twice daily.

Step by step solution

01

Understanding the Prescription Terms

The prescription for Dexamethasone sodium phosphate is for an intravenous (IV) route every 12 hours (q12h). This means the medication needs to be administered twice a day, at regular intervals of 12 hours between doses.
02

Identifying the Dosage

The required dosage for each administration is specified as 5 mg. This means each IV administration should deliver 5 mg of Dexamethasone sodium phosphate.
03

Determining the Number of Doses Per Day

Since the medication is ordered for administration every 12 hours (q12h), there are 24 hours in a day, resulting in two doses per day. Therefore, Dexamethasone sodium phosphate should be administered twice daily.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Dosage Calculation
Dosage calculation is a fundamental skill in pharmacology. It's all about determining the right amount of medication to administer to a patient. In our example, the order specifies that 5 mg of Dexamethasone sodium phosphate is needed for each dose. This involves understanding the prescription and accurately measuring the medication.
  • First, read the medication order carefully. Look for both the amount needed (5 mg in this case) and how it's being delivered (IV).
  • Make sure the medication you have matches the required dosage. Double-check to avoid any errors.
  • Understand if the dosage needs adjusting for factors like patient age or weight. This might not apply here but is important in many scenarios.
Always take your time with calculations and confirm them to ensure patient safety.
Intravenous Medication
Intravenous (IV) medication is a method of delivering drugs directly into the bloodstream. This approach allows for rapid absorption and effect since the medication bypasses the digestive system. It's crucial to administer the IV medication safely and accurately.
  • Ensure that the IV line is properly inserted and functioning.
  • Check that the medication is delivered at the correct rate to prevent complications.
  • Monitor the patient for any adverse reactions, which can occur due to the direct entry of medication into the circulation.
IV administration is common for medications that need to act quickly or are not absorbed well orally, like Dexamethasone.
Administration Frequency
The frequency of medication administration is important for maintaining the proper therapeutic levels of medication in the body. "q12h" means the medication should be administered every 12 hours.
  • This timing helps ensure consistent levels of medication are maintained throughout the day.
  • Creating a dosing schedule is beneficial to stick to this frequency and prevent any missed doses.
  • Administration frequency can affect how connected the patient feels to the treatment, impacting adherence. Therefore, clear communication about the schedule is vital.
Understanding administration frequency ensures that the treatment is both safe and effective.
