Notes chapter 17 Flashcards
Millieqivalent ?
Refer to the concentration electronically certain volume of solution express as milliequivalent per liter (mEq/L)
Body surface area is defined ? .
as the total area exposed to the outside environment
dimensional analysis?
method (also called factor labeling or the label factor method )
Dimensions analysis following three ?
1.Drug label
2.Conversion
3.Drug order
PROBLEM: The physician orders 40 mg of furosemide(Lasix). An ampule (small glass container that usually contains a single dose of a solution) of furosemide labeled “Lasix 20 mg/mL” is available.?
Example 1 pg 430

Example 4

example 5
PROBLEM: Trey, an 8-year-old, weighs 60 lb and is 51 inches tall. His body surface area (as determined with the nomogram in Fig. 17.1) is 1.0. If an adult dose is 50 mg, how many milligrams should Trey receive?

Pharmacology?
is the study of drugs (medications) and their action on the living body.
Lethal dose?
The amount of a drug that causes death
A metabolite?
is a substance produced by metabolic action,which results in the breakdown of the drug
A drug that builds up in the body is said to have a cumulative?
(increasing by increments)
-effect, which sometimes leads to toxic (harmful) or even lethal (deadly) outcomes tor the patient
stat?
-are planned to manage an emergency patient conditions
-they are to be complete before order
-is one time only dose
It is important for the nurse to be familiar with therapeutic ?
(beneficial) dosages of frequently used drugs to administer doses of medication competently to patient ?book
When one drug alters the action of another drug, it is called?
a drug interaction (a modification of the effect of a drug when administered with another drug).
When one drug increases the action or the effect of another drug, it is called ?
potentiation of the drug, or synergism.
Compatibility?
-is the quality or state of harmonious coexistence.
-Drug compatibility is the ability to administer medications together easily without any difficulty for the patient.
A drug that produces a predictable response at the intended site of action is called?
agonist
(its tell the cell to bind to receptor increase the function bind receptor /attract and encourage molecules bind cell)
is a drug that blocks the action of another drug.
- drugs are used to counteract the effects of a previously given drug
. Anatagonist
(-anatagonist is going to bind to the receptor prevent or block any molecules bond with receptor (prevent something to happen)
-A common antagonist prescribed is naloxone hydrochloride (Narcan) It is given when a person has received too much of an opioid medication,such as morphine sulfate.
An idiosyncratic?
reaction to a drug results from the individual’s unique hypersensitivity to it.
A reduced response to a drug over time is called a drug ?
tolerance
-The patient who has developed tolerance to a drug requires a larger dose of the drug to achieve the same effect that a smaller therapeutic dose once produced.
adverse drug reaction ?
(a harmful, unintended reaction to a drug administered at a normal dosage), drug hypersensitivity, or intolerance to the drug
