Study Notes

Types of Diagnostic Tests

Noninvasive tests do not involve inserting instruments into the body.
Invasive tests involve inserting instruments into the body's tissues, organs, or cavities.
Most invasive procedures require informed consent.

Informed consent is a communication process between a patient and their healthcare provider.
It often leads to agreement or permission for care, treatment, or services.
Patients must receive information about their condition, testing, and treatment options.
Every patient has the right to receive information and ask questions before procedures.
Informed consent is necessary if the adult patient is mentally capable of making their own decisions.

Preparing the Client for Diagnostic Testing

Ensuring client understanding and compliance with pre-procedural requirements.
Involving clients, families, and significant others in the testing process.
Advising clients about the estimated time required for the test.

Health Care Professional Role in Diagnostic Testing

Facilitating scheduling of tests.
Providing client education.
Performing or assisting with procedures.
Assessing clients for adverse reactions to procedures.

Further Responsibilities During Diagnostic Testing

Preparing the procedure room (e.g., ensuring adequate lighting).
Gathering supplies for the procedure.
Testing equipment to ensure functionality and safety.
Securing proper containers for specimen collection.

Pain or Anxiety Provoking Procedures: Sedation

Sedation (monitored anesthesia care) helps patients feel more comfortable and relaxed.
Levels of sedation include minimal, moderate, and deep.
General anesthesia is used for major surgeries/operations.
Local anesthesia is for pain management in a specific body part.

Sedation vs. General Anesthesia

Minimal sedation: Patients feel drowsy and relaxed with minimal effects on bodily sensations.
Moderate sedation (conscious sedation/procedural sedation): Patients are semi-conscious, able to breathe on their own, and can respond to stimulation.
Deep sedation: Patients are nearly unconscious, responding only to repeated, painful stimuli. They might need assistance with breathing, but cardiovascular function is usually unaffected.
General anesthesia: Patients are completely unconscious and unresponsive to any pain; breathing assistance and cardiovascular monitoring are necessary.

Care of the Client After Diagnostic Testing

Restoring the client to their pre-diagnostic level of functioning.
Monitoring clients for signs of respiratory distress and bleeding.
Monitoring intake and output (I&O) for 24 hours with some tests.
Providing written instructions upon discharge.

Brainstorming

Brainstorm a list of diagnostic procedures.
Estimate the required level of sedation for each procedure.
Justify your estimations.

Radiography

Radiography studies involve exposing film to X-rays or gamma rays.
This method is used by healthcare professionals to examine internal organs and structures.
Imaging methods used include X-rays, CT scans, mammography, fluoroscopy, and interventional procedures.

X-Ray

The most common radiological study.
Non-invasive, non-contrasted.
Image density is used to visualize internal structures.
Patients provide their names and dates of birth to the healthcare staff.

Computed Tomography (CT)

CT scanning involves X-ray beams to scan the body.
Radiation detectors gather and transmit the data to a computer.
The computer processes this data to create images of the body's internal structures.
The images provide measurements and a multidimensioned view of internal structures.

Fluoroscopy

Produces immediate, serial images of body structures and functions.
Helps visualize the movement of organs.
Often uses contrast materials for improved visualization.
Operates using video X-ray technology.

Barium Studies

Barium, a chalky white contrast medium, highlights internal digestive tract structures.
Used as an aid for other imaging techniques like fluoroscopy to visualize internal structures.
Types of barium studies include barium swallow, barium meal, and barium enema.

Angiogram/Arteriogram

X-ray procedure for arteries and veins.
Detects blockages or narrowings.
Involves inserting a thin tube into an artery (usually the femoral artery).
A contrast dye is injected for better visualization of vessels during the procedure.

Magnetic Resonance Imaging (MRI)

MRI uses radio waves and a powerful magnetic field to create cross-sectional images of the body.

Ultrasound

Non-invasive technique using high-frequency sound waves to visualize deep body structures.
Special ultrasound for the heart is called an echocardiogram.

Endoscopy and Colonoscopy

Visualization of body organs and cavities, including the digestive tract, with a scope.

Papanicolaou (Pap) Test

A smear method to examine stained exfoliative cells (cells that have been shed from the body).

Electrocardiogram (ECG)

Graphic recording of the heart's electrical activity.

Stress Test

Measures cardiovascular fitness.
Demonstrates the myocardium's ability to respond to increased oxygen demands.
Increases blood flow to coronary arteries during the test.

Thallium Test

Uses a radioactive isotope (thallium) and gamma rays.
Shows how well blood flows to the heart muscle.
Often used in conjunction with an ECG.

Electroencephalogram (EEG)

Graphic recording of the brain's electrical activity.

Skin Biopsy

Excision of a small tissue sample for diagnostic purposes.
Types of skin biopsies include: punch biopsy, shave biopsy, and excisional biopsy.

Aspiration

A procedure that withdraws fluid from an area that has collected abnormally.

Amniocentesis

Withdrawal of amniotic fluid to obtain fetal cells for examination during pregnancy.
Indications may include age over 35, prior spontaneous abortion, or family history of genetic conditions.

Paracentesis

Aspiration of fluid from the abdominal cavity (often due to ascites).

Thoracentesis

Aspiration of fluid from the pleural cavity.

Lumbar Puncture

Aspiration of cerebrospinal fluid (CSF) from the subarachnoid space.

Laboratory Diagnostic Tests – Urinalysis

Exam of urine sample detects health issues, including metabolic problems, urinary tract infections, and kidney dysfunction.

Reasons for Laboratory Tests

Detecting and quantifying the risk of future disease.
Establishing or excluding diagnoses.
Assessing disease severity.
Formulating a prognosis.
Guiding intervention selection.
Monitoring disease progression.
Assessing treatment effectiveness.

Accuracy in Laboratory Testing

Practitioners must accurately record orders of tests onto requisition forms.
Pertinent information that impacts test results should be included with each order.
Ensure correct specimen collection procedures are followed.
Verify patient identity using proper verification methods.
Laboratory results are recorded in the appropriate medical record.

Types of Specimen Collection

Specimens include stool, urine, blood (venipuncture, arterial puncture, capillary puncture), and other body fluids (aspirate from central venous lines, implanted ports).

Stool Tests Results

Stool tests can detect occult blood (blood in the stool only detected via microscope/chemical means).
Stool specimens can also identify parasites.

Types of Urine Collection

Different types of urine collection methods are used (random or timed 24 hour urine, collection from indwelling urinary drainage systems, sterile catheterized specimens, clean-voided specimens).

Additional Information from the uploaded text (new info):

Informed Consent: The process of communication explicitly involves information about the condition, treatment options, and associated tests. Adults who can make sound decisions must agree.
Preparing the Client: Families and significant others should be involved, and the expected time for the test explained.
Health Care Professionals: Their role includes arranging tests, teaching patients, performing (or helping with) the procedures, and assessing patient responses.
Further Responsibilities: Preparing the room, collecting supplies, and examining equipment function are crucial.
Pain/Anxiety: Local anesthesia is another way to relieve pain and anxiety from specific procedures; general and monitored anesthesia (sedation) are also commonly used.
Care After Tests: Post-procedure care seeks to return patients to their pre-test level of function; this often includes monitoring vital signs and providing written discharge instructions.
Accuracy in Lab Tests: Requisition forms need to have correct patient information and appropriate instructions for the tests.
Specimen Collection: Methods for stool, urine collection, and different types of blood collections are given in detail, including central lines and implanted ports, along with reasons for each of those methods.
Stool Tests: The results from stool tests can detect occult blood (blood not visible to the naked eye) or parasites (microscopic analysis may be required).
Urine Tests: This could include timed or random urine collection, and those collected from drainage systems.
Additional diagnostic tests: A wide range of diagnostic tests is mentioned, including those that use radio waves, gamma rays, contrast materials, or visualization via scopes
