Ms. Wayne is admitted at 0700 to induce labor. Refer to the eMAR for the following questions. Show your work. Logout Pt name: Linda Wayne MRN: 23-458 DOB: 12/07/1998 Room: 3211 Admit date: 02/14/2024 Allergies: NKA Attending: Dr. Sheets Close X MAR Scheduled All PRN 1200 0700 0800 1100 0900 1000 Oxytocin (PITOCIN) 10 units/1000mL Dose 2 mU/min :intravenous : continuous, increase by 2 mU every 20 minutes until active labor occurs 800 Magnesium 10g/500 mL Bolus : Dose 2 g : intravenous: over 30 minutes 0830 Magnesium 10g/500 mL : Dose 1 g/h : intravenous continuous after bolus 0900 Acetaminophen (TYLENOL) : Dose 650 mg: oral : every 4 h as needed for pain 1. How many mL/h will the nurse begin the oxytocin infusion at 0800? 2. The oxytocin has been increased every 20 minutes. What is the IV rate (mL/h) after 2 hours?

#1 is 12 mL/hr. I need help with #2 and it HAS to be in dimensional analysis.

Answer 1

1. Calculate Oxytocin infusion at 0800

Step 1:

$\small volume/hr = \frac{concentration per min}{concentration of solution}$

Ordered dose = 2mU/min

Concentration of oxytocin = 10Units/ 1000mL or 10mU/mL

Step 2:

Calculate the oxytocin infusion rate

$\fn_cm \small Volume/hr =\frac{2mUmin}{10mU/mL}\times 60$

Volume /hr = 12mL/hr.

The nurse begins Oxytocin infusion at a rate of 12mL/hr.

2. Calculate the Oxytocin infusion rate after 2 hours.

Step 1:

Here ordered increase of 2mU every 20 min.

2 hours means = 2 X 60 = 120min.

So at the end of 1 hr -------- 2mU---------- 4mU(20 min) ----------6mU(40min) ----------8mU(60min)

So at the end of 2 hr --------8mU ---------- 10mU(80 min) ---------- 12mU(100 min) ---------14mU(120/min)

Step 2:

After 2 hours, the nurse must infuse 14mU/ min.

$\fn_cm \small Volume/hr =\frac{14mUmin}{10mU/mL}\times 60$

Volume /hr = 84mL/hr.

The IV rate of Oxytocin after 2 hours is 84mL/hr.
