1. A client is admitted following a hip replacement. 2.5
The physician orders Dilaudid (hydromorphone) 5mg*1mL/2mg = 5mL/2 = 2.5 mL
5mg. The nurse has on hand Dilaudid 2mg/mL.
How many mLs will the nurse administer?
2. A client is receiving 80mg of methylprednisolone 1.6
q 6 hours. On hand there is 50mg/mL. How many 80mg*1mL/50mg = 80mL/50 =
mL will the nurse draw up for the first dose? 1.6 mL
3. A patient has an IV of 1 gram of Rocephin (ceftri- 300
axone) in 100mL D5W (dextrose in water) to run
over 20 minutes. How many mL per hour should
the pump be set at?
4. A patient has an IV of dextrose in water 500mL to 17
be infused over 5 hours. What will the drip rate
be in gtts/min using tubing with a drop factor of
10 gtts/mL?
5. A patient has an IV piggyback of Zithromax 30
(azithromycin) 500 mg in 240 mL of 0.9 NS to run
over 2 hours. The tubing has a drip factor of 15.
How many drops per minute should be adminis-
tered?

(azithromycin) 250mg in 500mL D5W to run over Question states that the prescrip-
an hour. If the nurse uses an IV controller, how tion runs over 1 hour and that the
many mL per hour will the nurse set the pump at? mL is 500.
