Answer 2

Bolus Dose Definition

Answer 3

Give Thanks to MedlinePlus for their wonderful (medical) dictionary, Let's add:

The term intravenous means - administered by entering a vein.
The definition of bolus is - a large dose of a substance (usually a large pill being crushed) given by injection for the purpose of rapidly achieving the needed therapeutic concentration in the bloodstream.

So, to add 1+1, an intravenous bolus dose is: a large dose crushed and administered intravenously, so that the patient can achive rapid therapeutic concentration in the bloodstream. An intravenous bolus dose is also a method used in clinical trials to determine dosage.

Hope this answers your question!

Answer 6

Let's break up the intravenous and bolus.

Intravenous describes one of the many ways to deliver a drug in pharmacology. Essentially, it involves the insertion of an plastic tubing into a vein. The drug is then administered through directly into the vein in a liquid form. This allows the drug to bypass the intestinal juices in the stomach. It is written as IV in a prescription. Other routes of drug administration include oral (written PO "per oral" in a prescription), through the rectum (written PR "per rectum" in a prescription), topical (written "TOP" in a prescription), subcutaneous injection (written "SC" in a prescription" etc etc.

The second word is bolus. There are usually 2 ways that a drug may be administered intravenously. Bolus or drip. A bolus dose is when the doctor injects the drug all at one shot into the vein, usually within seconds or minutes. Drip is when the drug is connected to a tubing and allowed to flow slowly into the vein. Different drugs have different pharmacokinetics and dynamics such that they may behave differently given in these 2 different ways. For example, 10 mmols of potassium chloride (KCL) given as an intravenous bolus dose will be fatal, causing heart arrhythmias, whereas 10 mmols of KCL given in a drip over 2 hours is commonly used to correct low potassium.

Hope this helps. I work in a hospital. This is part of everyday life.

Answer 7

It's a large stat dose of a medication given into a vein. It can sometimes be followed up by smaller doses at a later stage.

Answer 8

A large dose given for a fast blood level at beginning of therapy.

Answer 9

it is a syringe of medication injected either directly into a vein or through an iv tubing
when immediate results are required
ex. lasix for congestive heart failure to create an immediate diuretic effect
or glucose for a diabetic who is unresponsive from severe hypoglycemia

Answer 10

No idea except to guess that since a bolus is a deadly S. American weapon, it is an amount needed to kill?
