The order from a provider is: Administer Penicillin 3 gm IV on call to OR over 1 hour.  The pharmacy provides Penicillin 3 gm diluted in 150 mL of NS. The drop factor is 10  gtt/mL. What is the gtt/min
Answer and Explanation

The Correct Answer is ["25"]

Total Penicillin dose: 3 gm (as given in the order) 

Available volume: The pharmacy provides 150 mL of NS with the Penicillin already  diluted. 

Infusion time: 1 hour. 

Rate (mL/min) = Total volume (mL) / Total time (minutes) 

1 hour = 60 minutes

Rate (mL/min) = 150 mL / 60 minutes = 2.5 mL/min 

Drop factor: The drip factor is 10 gtt/mL, meaning 10 drops deliver 1 mL of solution. Rate (gtt/min): To find the rate in gtt/min, multiply the rate (mL/min) by the drip factor  (gtt/mL). 

Rate (gtt/min) = Rate (mL/min) x Drip factor (gtt/mL) 

Rate (gtt/min) = 2.5 mL/min x 10 gtt/mL = 25 gtt/min

Correct Answer is ["2525"]

Explanation

To calculate the total intake of the client, the nurse would add up all the fluids administered over the past 9 hours. The lactated Ringer's IV, which was given at a rate of 150 mL/hr for 9 hours, totals 1350 mL. The cefazolin was administered in 100 mL of 0.9% sodium chloride, and since it's an intermittent bolus, we count it once, adding 100 mL. The two units of packed RBCs add up to 525 mL (275 mL + 250 mL). The two IV bolus infusions of 0.9% sodium chloride are 500 mL in total (250 mL each). Lastly, the famotidine was given in 50 mL of 0.9% sodium chloride. Adding all these together, the nurse should record a total intake of 2525 mL for the client over the past 9 hours.

Correct Answer is ["0.6"]

Explanation

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).
