The doctor has ordered 5 mg of Haloperidol (Haldol) to be administered intramuscularly (IM) every 4 hours as needed for severe agitation. The medication is available in a concentration of 50 mg/mL. What is the maximum mL of Haloperidol the patient could receive in a 24-hour period if they receive the maximum number of doses.
The Correct Answer is ["0.6"]
To calculate the maximum milliliters (mL) of Haloperidol a patient could receive in a 24- hour period, we must first determine the number of doses. Since the medication is to be administered every 4 hours, and there are 24 hours in a day, the patient could receive up to 6 doses in a day (24 ÷ 4 = 6). Each dose is 5 mg, and the medication's concentration is 50 mg/mL. Therefore, each dose would be 0.1 mL (5 mg ÷ 50 mg/mL = 0.1 mL). Over a 24-hour period, the maximum amount of Haloperidol the patient could receive is 0.6 mL (0.1 mL/dose × 6 doses).

Correct Answer is ["56"]
Explanation
To calculate the flow rate for an IV infusion, you can use the formula: (Volume in mL x Drip factor) / Time in minutes. In this case, the nurse has 500 mL of Ringer's lactate to infuse over 3 hours. First, convert the hours into minutes: 3 hours x 60 minutes/hour = 180 minutes. Next, multiply the volume by the drip factor: 500 mL x 20 gtt/mL = 10,000 gtt. Finally, divide by the total time in minutes: 10,000 gtt / 180 minutes = approximately 55.56 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver around 56 gtt/min.
