How many mL of morphine is required to administer 4 mg, given a concentration of 10 mg/mL?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Answer: (B)

To determine how many milliliters of morphine are needed to administer a dose of 4 mg with a concentration of 10 mg/mL, you can use the formula: Volume (mL) = Desired Dose (mg) / Concentration (mg/mL) Plugging in the values: Volume (mL) = 4 mg / 10 mg/mL = 0.4 mL This calculation shows that to achieve the 4 mg dose, 0.4 mL of the morphine solution is required. This confirms that the answer is accurate, as administering 0.4 mL will provide the exact amount of morphine needed at the specified concentration. Understanding this dosage calculation is crucial as it ensures that the medication is given safely and effectively.
