Answer :
Answer:
The nurse will administer a total of 1.67 mL of medication.
Explanation:
Step 1: Calculate the volume of morphine to be administered
The prescribed dose of morphine is 10 mg, and the concentration of morphine is 15 mg/mL.
Volume of morphine = Prescribed dose / Concentration
Volume of morphine = 10 mg / 15 mg/mL
Volume of morphine = 10 / 15
Volume of morphine=0.67 mL
Step 2: Calculate the volume of promethazine to be administered
The prescribed dose of promethazine is 25 mg, and the concentration of promethazine is 25 mg/mL.
Volume of promethazine = Prescribed dose / Concentration
Volume of promethazine = 25 mg / 25 mg/mL
Volume of promethazine = 1 mL
Step 3: Total volume of medication to be administered
Add the volumes of morphine and promethazine:
Total volume = Volume of morphine + Volume of promethazine
Total volume = 0.67 mL + 1 mL
Total volume = 1.67 mL
