How is bolus rate calculated?
First, convert grams to milligrams: 2 g → 2000 mg.
Next, determine the concentration: 2000 mg per 500 ml = (2000/500) X (mg/ml) = 4 mg/ml.
Since you’re using a 60 drop set, you multiply your VTBI by the drip factor.
Then divide by the concentration of 4 mg/ml..
What does it mean to run an IV wide open?
If a patient needs a lot of fluid fast, the roller clamp is opened all the way to allow for maximum flow. Since the clamp is open all the way, the IV is “Wide open” If we need even more flow, we use a pressure infuser. It’s a bladder that inflates like a blood pressure cuff against the IV bag.

What is a bolus of normal saline?
1) Fluid Bolus: This route is normally used in the acute care setting when a rapid infusion of fluids is necessary (e.g., hypovolemia). Delivery of fluid should be administered through large-bore peripheral lines or via central-line access.
How do you give atropine IV push?
Administer Atropine 0.5 mg IV repeating every 3-5 minutes to a total dose of 3 mg IV, until a heart rate of greater than 60/minute is reached. 3. Transcutaneous pacing (TCP) when available may be initiated prior to establishment of IV access and/or before Atropine begins to take effect.
What is an IV bolus used for?

How long does it take to bolus 1 liter?
You should be able to get a litre in over a handful of minutes (should definitely be less than 10 minutes). For children, you would probably aim more for a 20 mL/kg bolus rather than 10 mL/kg and you wouldn’t round off. An 8 kg child should get a 160 mL bolus of saline.
What is bolus dosing?
Listen to pronunciation. (BOH-lus…) A single dose of a drug or other substance given over a short period of time. It is usually given by infusion or injection into a blood vessel.
