2. Listen for gurgling sound in stomach with stethoscope
3. Listen for breath sounds
4. Put medication in tubing
5. Let medication run down by gravity
6. After mediation is almost out of the tubing add at least 50
mL of water or according to the institution’s policy to flush and clean out the tubing.
7. Reclamp the tube.
8. Leave tube clamped for at least 30 minutes before the suction tube is reattached so that there is time for the medication to be absorbed.
. Intramuscular (IM)
. Intravenous (IV) injections
. The action of the medicine is required quickly
. Gastric enzymes might destroy the medication
. The medication might be removed from the body on a “first pass” through the liver before it can get to the tissues in the body where it will act
. Mediation must be given at a steady rate to provide a constant blood level
. The medication is not available in enteral form
2. Th barrel: the container for the medication. The calibrations are printed numbers on the barrel, and they indicate the amount or volume of medication in either minims (m), milliliters (mL), units, or cubic centimeters (cc)
3. The plunger: the inner portion that fits into the barrel. The medication is forced out through the needle when the plunger is pushed into the barrel.
2. The shaft: which is the hollow part through which the medication passes.
3. The pointed/beveled tip: pierces the skin
** the longer the pointed tip of the needle, the more easily the needle enters the skin**
** ex. A 25-gauge needle is smaller than a 17-gauge needle**
** generally the smaller the needles (gauge), the shorter it is in length.**
**ex. 26-gauge (smaller hole) with length of (3/8) in to (1/2) in.**
Subcutaneous: 25-27 gauge; (1/2)-1 inch; 0.5-2 mL to be injected.
Intramuscular: 20-23 gauge; 1-2 inch; 0.5-2 mL to be injected
Intravenous: 15-22 gauge; (1/2)-2 inch; unlimited volume can be injected.
** there is greater emphasis on sterile technique in giving parenteral medications because the risk of infection is high**
** needles are always inserted with bevel up to inspect the needle as it goes in the stopper. **
** THE NEEDLE IS ALWAYS CHANGED BEFORE ADMINISTRATION!!** because forcing the needle through the rubber diaphragm may make it dull or create sharp irregular edges called burrs that would produce pain. (Pg. 105)
