1. To calculate the ml/hr to set the IV pump, we need to determine the flow rate. The total volume (1000ml) is to be infused over 8 hours (8 br = 8 hours) or 480 minutes.
Flow rate (ml/hr) = Total volume / Time (minutes)
Flow rate (ml/hr) = 1000ml / 480 minutes
Flow rate (ml/hr) ≈ 2.08 ml/hr
2. To calculate the gtt/min using 20 gtt/mL IV tubing, we need to know the flow rate in ml/hr. Using the result from question 1, we can calculate the gtt/min.
Flow rate (ml/hr) = 2.08 ml/hr
Gtt/min = Flow rate (ml/hr) * Drop factor (gtt/mL)
Gtt/min = 2.08 ml/hr * 20 gtt/mL
Gtt/min ≈ 41.6 gtt/min (Round to the nearest whole number: 42 gtt/min)
3. To calculate the ml/hr to set the IV pump to deliver the Cipro, we need to determine the flow rate. The total volume (200ml) is to be infused over 60 minutes.
Flow rate (ml/hr) = Total volume / Time (minutes)
Flow rate (ml/hr) = 200ml / 60 minutes
Flow rate (ml/hr) ≈ 3.33 ml/hr
4. To calculate how many capsules of Colace to give, we need to know the desired dose. The order states 100mg PO bid (twice a day). We will assume the patient will be taking it twice a day.
Dose (mg/day) = Desired dose (mg/dose) * Frequency (doses/day)
Dose (mg/day) = 100mg/dose * 2 doses/day
Dose (mg/day) = 200mg/day
To find the number of capsules to give, we need to divide the total dose by the strength of each capsule.
Number of capsules = Dose (mg/day) / Strength of each capsule (mg/capsule)
Number of capsules = 200mg/day / 100mg/capsule
Number of capsules = 2 capsules
5. The question is incomplete. Please provide the complete information for the calculation.
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
