CHN P1 PRINCIPLES AND TECHNIQUES IN THE USE OF PHN BAG Flashcards
requently called the PHN bag, a tool used by the nurse during home
and community visits to be able to provide care safely and efficiently
nursing bag
is a professional, purposeful interaction that takes place in the family
residence aimed at promoting, maintaining, or restoring the health of the family are its
members. It is a family nurse contactor, instead of the family going to the nurse, the nurse
goes to the family
home visit
is an organic acid with the formula CH3-COOH. Its functional group is
carboxylic acid group.
Acetic acid
is a monocarboxylic acid because it contains only one
“COOH”group. It has a sour taste and pungent smell. It is the main component of vinegar.
Vinegar is typically 3-7% solution of acetic acid in water
Acetic acid
s mainly used as a
preservative in food and in the pickling of vegetables. Water free acetic acid is known as
glacial acetic acid.
Vinegar
t is used to test for simple carbohydrates.
-t identifies
reducing sugars (monosaccharide’s and some disaccharides), which have free ketone or
aldehyde functional groups
-can be used to test for the presence of glucose
in urine.
Benedict’s Test
Some sugars such as glucose are called
reducing sugars
they are capable of
transferring hydrogens (electrons) to other compounds, a process called reduction
reducing sugars
contains potassium thiocyanate and is used to
determine how much reducing sugar is present. This solution forms a copper thiocyanate
precipitate which is white and can be used in a titration. The titration should be repeated
with 1% glucose solution instead of the sample for calibration
Benedict’s quantitative reagent
DO NOT react positive with the Benedict’s
test unless they are broken down through heating or digestion (try chewing crackers and
then doing the test).
Complex carbohydrates
is a non-reducing sugar and does also not
react with the iodine or with the Benedict Reagent. Sugar needs to be decomposed into its
components glucose and fructose then the glucose test would be positive but the starch test
would still be negative.
Table sugar (disaccharide)
measures the glucose levels in your blood
blood glucose test
helps move glucose
from your bloodstream into your cells.
insulin
may be a sign
of diabetes, a disorder that can cause heart disease, blindness, kidney failure and other
complications.
High blood glucose levels (hyperglycemia)
can also lead to major health
problems, including brain damage, if not treated.
Low blood glucose levels (hypoglycemia)
is used to find out if your blood sugar levels are in the healthy
range. It is often used to help diagnose and monitor diabetes.
A blood glucose test
is a method to tell what type of blood you have. B
Blood typing
s done so
you can safely donate your blood or receive a blood transfusion. It is also done to see if you
have a substance called Rh factor on the surface of your red blood cells.
Blood typing
involves collecting tissue or fluids for laboratory analysis or
near-patient testing, and may be a first step in determining a diagnosis and treatment.
Specimens must be collected at the right time, using the correct technique and equipment,
and be delivered to the laboratory in a timely manner.
SPUTUM SPECIMEN COLLECTION
in the respiratory tract is a normal process. It is secreted from
goblet cells found in the surface epithelium lining the airways of the respiratory tract and
from seromucous glands in the connective tissue layer beneath the mucosal epithelium.
Mucus production
n is to identify the bacterial, viral or fungal cause of a
suspected infection and its sensitivities to antibiotics
