Final answer:
To find out how many mL the nurse will give, we need to convert the order for morphine gr 1/10 to mL using the pharmacy's morphine concentration. The nurse will give 0.6 mL of morphine.
Step-by-step explanation:
To find out how many mL the nurse will give, we need to convert the order for morphine gr 1/10 to mL. The pharmacy has morphine available in a concentration of 10mg/mL. To convert from gr to mg, we need to multiply by a conversion factor of 60, as there are 60 mg in 1 gr. Therefore, 1/10 gr is equal to 6 mg. Now, to find the mL, we divide the mg by the concentration of morphine, which is 10 mg/mL. So, the nurse will give 0.6 mL of morphine.
