assessment
means the evaluation or appraisal of the patient’s condition
overall appearance
how appropriately the patient is dressed, whether any body odor, signs of possible difficulties with self-care
emotional affect
refers to patients expression, tone of voice, mood, and emotions
ambulation
means the way the patient walks, including gait, any unsteadiness, or possible difficulty
vital signs
are four key indications that the body systems are functioning; temperature, pulse, respiration, and blood pressure (VSS)
temperature
on average, the normal body is 98.6F or 37.0C
fever
most commonly caused by an infection, an injury, or medication. an oral body temp. of 100F or higher
hyperthermia
an extremely high fever
hypothermia
an abnormally low body temperature
pulse
the rhythmic pressure against the walls of an artery that is caused by the beating of the heart
respiration
known as respiratory rate (RR), the number of complete breaths per minute
blood pressure (BP)
the force of the blood against the walls of the arteries
sphygmomanometer
measures BP, when using manual style, a stethoscope is required to listen to the blood sounds
systolic
the first beat heard when recording blood pressure
diastolic
the last beat hear, when recording blood pressure
pain
considered to be the 5th vital sign, can be measured objectively, must be reported by patient
acute pain
comes on quickly, can be severe and lasts only a relatively short time
chronic pain
can be mild or severe, persists over a longer period of time than acute pain and is resistant to most medical treatments
auscultation
means listening for sounds within the body and is usually performed through a stethoscope
rales
known as crackles, are abnormal crackle-like lung sounds heard through a stethoscope during inspiration (breathing in)
rhonchi
are coarse rattling sounds that are somewhat like snoring, usually caused by secretions in the bronchial airways
stridor
an abnormal, high-pitched, musical breathing sound caused by a blockage in the throat or in the larynx(voice box)
lubb sound
is heart first. caused by the tricuspid and mitral valves coming between the atria and the ventricles
dupp sound
which is shorter and higher pitched, is heard next. caused by the closing of the semilunar valves in the aorta and pulmonary arteries as blood is pumped out of the heart
bruit
an abnormal sound or murmur heard during auscultation of an artery, usually due to a partially blocked, narrowed or diseased artery
thrill
an abnormal rhythmic vibration felt when palpating an artery
heart murmur
an abnormal heart sound that is most commonly a sign of defective heart valves
abdominal sounds
known as bowel sounds, are normal noises made by the intestines.
palpation
an examination technique in which the examiner’s hands are used to feel the texture, size, consistency, and location of certain body parts
percussion
a diagnostic procedure designed to determine the density of a body part but the sound produced by tapping the surface with the fingers
ophthalmoscope
an instrument used to examine the interior of the eye
otoscope
an instrument used to visually examine the external ear canal tympanic membrane
speculum
an instrument used to enlarge the opening of any canal or cavity, especially the vagina, to facilitate inspection of its interior
stethoscope
an instrument used to listen to sounds within the body
recumbent
describes any position in which the patient is lying down
decubitus
describes the patient lying in a recumbent position
horizontal recumbent postion
known as supine position, the patient is lying on the back, face up. used for examination and treatment of the anterior surface of the body and for x-rays
dorsal recumbent postion
the patient is lying on the back, face up, with the knees bent. used for examination and treatment of the abdominal area and for vaginal or rectal examinations
lithotomy position
the patient is lying on the back, face up, with the feet and legs raised and supported in stirrups. used for vaginal and rectal examination and during childbirth
prone postion
patient is lying abdomen face down, arms may by placed under the head for comfort. used for the back and buttocks
sims’ position
the patient lying on the left side with the right knee and thigh drawn up with the left arm placed along the back. used for rectal area
knee-chest position
patient is lying face down with he hips bent so that the knees and chest rest on the table
LABORATORY TESTS
ENDOSCOPY AND CENTESIS
stat
the results are needed immediately, and the tests have top priority in the laboratory
profile
means tests that are frequently performed as a group on automated multi-channel laboratory testing equipment
phlebotomist
a medical professional who is trained to draw blood from patients for various laboratory tests and other procedures
phlebotomy
known as venipuncture, is the puncture of a vein for the purpose of drawing blood
arterial stick
the puncture of an artery, usually on the inside of the wrist, to obtain arterial blood
capillary puncture
the technique used when only a small amount of blood is needed as a specimen for blood test….known as finger, heel, or earlobe stick
complete blood cell count (CBC)
a series of tests performed as a group to evaluate several blood conditions
erythrocyte sedimentation rate (ESR)
known as a sed rate, a test based on the speed with which the red blood cells separate from the plasma and fall to the bottom a specialized test tube
hematocrit
describes the percentage, by volume, of a blood sample occupied by red cells
platelet count
measures the number of platelets in a specified amount of blood and is a screening test to evaluate platelet function
red blood cell count (RBC)
a determination of the number of erythrocytes in the blood. a depressed count can indicate anemia or an acute hemorrhage
total hemoglobin test (Hb)
usually part of a complete blood count; elevated Hb levels indicate a higher than normal hemoglobin concentration in the plasma due to ploycythemia
white blood cell count (WBC)
a determination of the number of leukocytes in the blood. an elevated count can be an indication of infection or inflammation
white blood cell differential count
tests to see what percentage of the total white blood cell count is composed of each of the five types of leukocytes
basic metabolic panel
a group of eight specific blood tests that provide important information about the current status of the patient’s kidneys blood sugar, calcium levels
blood urea nitrogen test (BUN)
measures the amount of nitrogen in the blood due to the waste product urea, performed to obtain an indication of kidney function
urea
is the major end product of protein metabolism found in urine and blood
C-reactive protein test (CRP)
performed to identify high levels inflammation within the body, produced but the liver only during episodes of acute inflammation
lipid panel
measures the amounts of total cholesterol, high-density lipoprotein (HDL), (LDL), in a blood sample
prothrombin time (PT)
known as pro time, a coagulation test used to diagnose conditions associated with abnormalities of clotting time and to monitor anticoagulant therapy
serum bilirubin
measures the ability of the liver to take up, process, and secrete bilirubin into the bile, to see if a patient has liver disease or a blocked bile duct
thyroid-stimulation hormone assay
measures circulating blood levels of thyroid-stimulating hormone (TSH) than can indicate abnormal thyroid activity
