A 58 year-Old male is admitted to the medical/surgical unit following surgery for transurethral resection of prostrate. The physician's post-operative orders include:
• Admit to the medical/surgical unit
• Monitor intakes and output
• Monitor urinary output hourly
• Vitals every 2 hr
• Monitor for symptoms of TURP syndrome
• Adjust rate of continuous bladder irrigation (CBI) 3 liter bags of sterile normal saline to maintain patent catheter, adjust rate to maintain pink to clear urine, and maintain urinary catheter traction
• IV D5W/0.45% normal saline 1000ml/8 br
• Ciprofloxacin (Cipro) 400 mg IV every 12 hr
• Docusate sodium (colace) 100 mg PO bid
• Dimenhydrinate 25 mg IV every 4 hr prn
• Acetaminophen (Tylenol) 300 mg with 30 mg of codeine PO 1 to 2 tablets every 4 to 6 hrs prn
• Discontinue IV when drinking well
• Complete blood count, electrolytes, creatinine in am
• Identify. the orders that require calculations
• Set up and solve each problem using dimensional analysis. Show all work
1. Calculate how many ml/hr to set the IV pump.
Supply: D5% NS W/0.45% NS 1000ml bag (show all work)
To calculate how many ml/hr to set the IV pump, we will use the formula:
(ml/hr) = (total volume to be infused) / (total time in hours)
In this case, the total volume to be infused is 1000ml and the total time is 8 hours.
(ml/hr) = 1000ml / 8 hours
(ml/hr) = 125ml/hr
Therefore, the IV pump should be set at 125ml/hr.
To calculate how many ml/hr to set the IV pump, we need to use dimensional analysis.
Given: D5% NS W/0.45% NS 1000ml bag
First, convert the time from hours to minutes since the IV pump is set in ml/hr.
1 hour = 60 minutes
Next, set up the dimensional analysis equation to convert ml/hr:
(ml/hr) = (1000ml bag) / (8 hours) * (60 minutes)
Now, let's solve the equation:
(ml/hr) = (1000ml) / (8 hr) * (60 min)
(ml/hr) = 1000 / 8 * 60
(ml/hr) = 12,500 / 8
(ml/hr) = 1562.5
Rounded to the nearest whole number, the IV pump should be set at approximately 1563 ml/hr.
