Kidney, Ureters, and Bladder (KUB) Intravenous Pyelography (IVP), Retrograde Pyelography
What are the stages of Specimen Collection?
1) Provide client comfort, privacy and safety.
2) Explain the purpose of the specimen collection and the procedure for obtaining the specimen
3) Use the correct procedure for obtaining a specimen or ensure that the client or staff follows correct procedure.
What is the major focus of the pretest phase?
Client preparation
Prior to radiologic tests, it is important to ask female patients if (answer) is possible.
Pregnancy
What is the measure of the solute concentration of the blood?
Serum Osmolality
Included in serum osmolality are…
Sodium ions
Glucose
Urea (BUN)
How do you estimate serum osmolality?
Doubling the serum sodium
What is the purpose of a stool specimen?
To determine the presence of occult blood.
To analyze for dietary secretions.
To detect the presence of ova and parasites in stool.
To detect the presence of bacteria and viruses
Direct visualization using a cystoscope
Cystoscopy
This phase focuses on the nursing care of client and follow-up activities and observations.
Posttest
is often conducted when a client is taking a medication with a narrow therapeutic range.
Therapeutic drug monitoring
Indicates the highest concentration of the drug in the blood serum
Peak level
Indicates the lowest concentration of the drug in the blood serum
Trough level
a commonly used diagnostic tool to evaluate the partial pressure of gas in blood and acid-based content.
Blood gas analysis
Specimens of arterial blood are taken from the…
Radial, Brachial or femoral arteries
Prevent (answer) by applying pressure to the punction site for about (answer) minutes after removing the needle.
Hemorrhaging: 5-10 minutes
Other name for Guaiac Stool Examination
Occult Blood Examination
Provides a graphic recording of the heart’s electrical activity.
Electrocardiography
Are recorded through an electrocardiogram or ECG
Waves
What should you consider in Nursing diagnoses?
1) Anxiety
2) Lack of knowledge
3) Fear
Common chemistry examinations include…
1) Lactic Dehydrogenase (LDH)
2) Creatine Kinase (CK)
3) Aspartate Aminotransferase (AST)
4) Alanine Aminotransferase (ALT)
5) Serum glucose, hormones such as Thyroid hormone, and other substances such as cholesterol and triglycerides
To assess a client’s response to an increased cardiac workload during exercise
Stress Electrocardiography
Commonly used diagnostic tests that can provide information about hematologic system and many other body systems.
Blood tests
Performed through a venipuncture
Blood tests
Urine specimens
1) Clean Voided Urine Specimens
2) Clean Catch or Midstream Urine
3) Timed Urine Specimen
4) Indwelling Catheter Specimen
puncture of a vein for collection of a blood specimen
Venipuncture
Usually done on the first voided specimen in the morning because it tends to have a higher, more uniform concentration, and a higher pH
Clean Voided Urine Specimens
Done when a urine culture is ordered when identifying the microorganisms causing UTI
Clean Catch or Midstream Urine
A collection of all urine produced and voided over a specific period of time ranging from 1 to 2 hours or 24 hours
