Question 3

The most common type of syringes are;

Answer 3

hypodermic syringe, insulin syringe,
and tuberculin syringe.

Question 4

✓ comes in 2,3 and five ml when it
comes to small sizes.
✓ Choice of syringe depends on
many factors such as medication,
location of injection and type of
tissue.
✓ Syringe ranging from one to three
ML may have two scales marked
on them, the minim and the
milliliter.

Answer 4

❖ Hypodermic Syringe

Question 5

✓ the scale is specially designed for
insulin, a 100 unit calibrated scale
intended for use with insulin this is
the only syringe that should be used
to administer insulin this syringes
frequently have an nonremovable
needle

Answer 5

❖ Insulin Syringe

Question 6

Was originally designed to
administer tuberculin solution.
✓ It is a narrow syringe calibrated in
tenths and hundreds of a milliliter,
up to 1 mill on one scale and in
sixteenths of the minim up to one
minim on the other scale. This type
of syringe can also be useful in
administering other drugs,

particularly when small or precise
measurement. this indicated such
as in pediatric dosages

Answer 6

Tuberculin syringe

Question 7

which connects with the needle.

Answer 7

be used.

Answer 12

TRUE

Question 13

which fits onto the syringe.

Answer 13

1. Hub,

Question 14

which is attached
to the hub.

Answer 14

Cannula or shaft,

Question 15

which is the slanted part at
the tip of the needle. A disposable
Needle has a plastic hub.

Answer 15

Bevel,

Question 16

may be short or
long. Longer bevels provide the
sharpest needles and cause less
discomfort.

Answer 16

Length of the Bevel-

Question 17

varies from 1⁄2 to 2
inches. The length is chosen according
to the clients muscle development, the
client’s weight, and the type of
injection.

Answer 17

Length of the shaft-

Question 18

TRUE OR FALSE Short bevels are used for
intradermal and intravenous injections.
Because a long bevel can become
occluded if it rests against the side of a
blood vessel.

Answer 18

TRUE

Question 19

diameter of the shaft. Smaller gauges
produce less special trauma, but larger
gauges are necessary for viscous
medications. Such as penicillin.

Answer 19

GAUGE

all other tests.

Answer 22

An Intradermal injection

Question 23

Generally a gauge 25, 5-8 inch needle is
used for adults of normal weight and
the needle is inserted at a 45 degree
angle.
 A 3-8 inch needle is used at a 90 degree
angle. A child may need a 1⁄2 inch needle
inserted at a 45 degree angle.
 One method nurse is used to determine
length of needle is to pinch the tissue at
the site and select a needle length that
is half the width of the skin fold to
determine the angle of insertion.
 A general rule to follow relates to the
amount of tissue that can be pinched or
grasped at the site.
 A 45 degree angle is used. When one
inch of tissue can be grasped at the site,
 A 90 degree angle is used. When two
inches of tissue can be grasped.

Answer 23

SC INJECTION

Question 24

➢ Injections into muscle tissue or
intramuscular IM injections are
absorbed more quickly than
subcutaneous injections because of the
greater blood supply to the body.
➢ Muscles can also take a larger volume
of fluid without discomfort than
subcutaneous tissues can, although the
amount varies among individuals.
➢ Chiefly based on muscle size and
condition in the side used, an adult with
well developed muscles can usually
safely tolerate up to 3ML of medication
in the gluteus medius and gluteus
maximus muscles.
➢ A volume of 1 to two ML is usually
recommended for adults with less
developed muscles in the deltoid
muscle. Volumes of .5 to 1 ML are
recommended. Usually A3 to 5ML
syringe is needed. The size of syringe
used depends on the amount of
medication being administered.
➢ The standard prepackage intramuscular
needle Several factors. Indicate the size
and length of the needle to be used.
First is the muscle. Next is the type of
solution, the amount of adipose tissue
covering the muscle, and the age of the
client.
