Terms in this set (48)
Process of reviewing data, observing a patient, and using screening tools to identify the individual's potential to benefit from further assessment.
Used to determine severity of a disease, monitor the stage and course of a disease, detect recurrence, estimate prognosis, and help make decisions about the best plan of care or approach for medical management.
-Noninvasive imaging system in which multiple x-ray beams and computer calculations provide a cross-sectional view of the body.
-Advantage: they can be used quickly to examine patients with internal injuries from trauma.
-Help physicians to diagnose and study cancers, cardiovascular disease, musculoskeletal disorders, liver diseases, trauma, infections or inflammatory conditions.
-Provides information on pericardial effusions, blood clots, tumors, arrhythmias, cardiomyopathy, aortic aneurysms, endocarditis, and heart valve functioning along with direction and velocity of blood flow.
-Used in stress tests
-No associated risks, no activity restrictions after test.
-Record of electrical conduction of heart, generated during cardiac cycle
-Identifies cardiac rhythm abnormalities, problems with conduction, pericardial disease, injury or damage to myocardium, including hypertrophy, as well as diagnosing non-cardiac related disorders.
-Noninvasive, short, painless
-Records brains electrical activity
-Commonly ordered for patients with epilepsy or seizures.
-Therapy is not limited before or after procedure
-Assists with determining source of neuromuscular weakness and atrophy, identifies muscle diseases, peripheral neuropathies, radiculopathies, entrapment neuropathies, and differentiating between myopathies and neuropathies.
-May be contraindicated for patients taking coagulants because of risk of bleeding
-Usually done in conjunction with nerve conduction test
Nerve Conduction Test
-Measures conduction velocity of impulse traveling between 2 points
-Assesses peripheral nerve injuries and discriminates between nerve disease and muscle injury
-Mild shock, unpleasant sensation
-Allows direct visualization of body organs and cavities through use of fiberoptic lens attached to rigid or flexible tube
-Assist with screening, diagnosis, and intervention of areas not easily accessed without open surgery
-Therapists may defer treatment immediately after procedure because patient may still be feeling effects of sedation
Tendon repair, ligament repair, meniscus repair
Transurethral resection of prostate/superficial bladder tumors, urethral stent placement, removal of ureteral and bladder calculi
Cholecystectomy, hiatal hernia repair, inguinal hernia repair, video-assisted colectomy
Wedge lung resection, video-assisted lung resection
-Collection of cerebrospinal fluid
-Patient on bedrest for 2-4 hours after procedure
-Diagnosis diseases of brain or spinal cord in infectious and inflammatory conditions
-Noninvasive, uses superconductive magnets, radiofrequency waves, and computers to provide a detailed sectional image of the body.
-No exposure to radiation
-Therapy to be deferred until results are known
Stages cancers and detection of metastasis, provides physiology and metabolism info.
Noninvasive, used in diagnosis and screening of pulmonary restrictive and obstructive diseases that impact breathing.
-Examine soft tissue and bony structures of the body
-Used to detect abnormalities of the heart, lungs, GI tract, and thyroid
Noninvasive, studies soft-tissue structures and provides info on size, shape, and position of organs. Less expensive than CT/MRI
-Indicate the overall health of the patient and provide information about why occupational performance may be affected or reasons therapy should be deferred.
-Determined through examination of a patient's body fluids and bloodwork.
-Range of normal values
-Provides a baseline against which a patient's laboratory values can be compared.
-Based on 95% of population norms
Complete Blood Count
-One of the most commonly ordered lab tests.
-May be referred to as routine chemistry
-Examines components of blood sample, screens for diseases, make a diagnosis, or monitor medical treatments and effects of drug dosages.
White Blood Cells Test
-Small percentage of blood volume
-Important for immune system
-Usually lowest in the morning
Increased WBC count, sign of infection
-Decreased WBC count
-Caused by bone marrow disorders or depression, aplastic anemia, pernicious anemia, HIV infection, autoimmune diseases, radiation or chemotherapy, drugs, alcoholism, or diabetes.
Absolute Neutrophil Count
-Measure of percentage of WBCs that are neutrophils
-Multiply WBC count by percentage of neutrophils
Low neutrophil count. Patients are at risk for nocosomial infections.
-Protein within RBCs that binds with oxygen, circulating oxygen throughout body.
-Measures blood's capacity to carry oxygen
-Gives arterial blood red color
-Abnormal values can indicate extent of anemia as well as patient response to treatment.
-Measure percentage of RBCs in total blood volume
-Quick test for anemia
Red Blood Cells Test
-Reflects number of red blood cells in blood and capacity to transport oxygen and nutrients throughout body.
-Provides oxygenation to tissues and remove/transport carbon dioxide from tissue to lungs where it is exhaled.
Too many platelets produced
Too few platelets present in blood
Basic Metabolic Panel
-Measures electrolyte-levels, acid or base balance, renal function, and blood sugar levels.
-An electrolyte imbalance can profoundly affect multiple body systems activity tolerance and ability to engage in occupations.
-Level/amount of sugar in blood
-One of the main sources of energy in blood
Low blood glucose levels; <60 mg/dl
High blood glucose levels; >250 mg/dl
-The amount of time it takes for blood to clot
-Used for patients on anticoagulation medications
-High values = bleeding risk
-Measurement of the effectiveness of anticoagulation medications
-Standardized test for measuring blood clotting times
-More reliable than PT, PPT, or aPPT tests as values are more uniform.
-High = risk for bleeding
-Measures blood glucose levels over an extended period of time, unlike the traditional glucose test that measure the patient's blood glucose levels after having fasted for a number of hours.
-Measure the average levels of glycohemoglobin present in blood for the 3-4 months prior to the test.
Arterial Blood Gases
-Analysis that assesses cardiopulmonary function, oxygen and carbon dioxide in the blood, and acid-base regulation by checking blood pH, partial pressure of oxygen and carbon dioxide, bicarbonate, and oxygen saturation levels
-May be ordered for patients with breathing problems or lung disorders.
-Collected from arterial system
Marker for heart attack or other muscle damage, measures the presence of the enzyme CPK in blood (creatine phosphokinase)
Regulatory proteins found in heart muscle that are released with cardiac damage or injury.
Protein made by liver, helps keep fluid within blood vessels and tissues. Helps to nourish tissues and transports vitamins, minerals, enzymes, and hormones.
Decreased exercise tolerance, close monitoring of vitals and rest breaks
Heart has to work harder to ensure sufficient oxygen is transported to rest of body; modify therapy as appropriate; defer therapy if patient is symptomatic
-Heart muscle is especially susceptible to potassium imbalances which can lead to arrhythmias or cardiac arrest
-Consider deferring therapy because of increased risk of arrhythmia or tetany, especially in patients with cardiac history.
-At risk for bleeding or bruising
-Can be therapeutic, but takes several days to reach that point
-Skin integrity may be compromised
-Extra care to prevent skin shearing during bed mobility/transfers
-Aiding nursing staff with bed positioning or prevention of skin breakdown may be necessary
