SPECIMEN COLLECTION
Collection and Transport PPT
| Question | Answer |
|---|---|
| Which organization designed a formal layout for Standard Operation Procedure manuals? | CLSI |
| What are two forms of identification needed when attempting to identify a patient verbally? | Spell out first and last name Unique identifier (DOB) |
| What should you do if there is not a wristband available for nonverbal patient identification? | Notify the Nurse in charge |
| What PPE is required for patients in isolation for infectious disease? | - disposable gowns + gloves |
| What is the meaning of a "reverse precaution"? | The patient is to be protected from infectious agents |
| Explain the difference between plasma and serum | Plasma is the liquid portion that still contains clotting factor because it represents our blood in vivo (in our bodies). Serum is the liquid portion that does not contain clotting factor because the blood cells coagulated already |
| Why is plasma preferred in microscopic analysis rather than serum? | When coagulation occurs, the blood cells clump together. Because the blood clots, we lose a significant amount of the clotting factors. it prevents us from seeing cellular elements under a microscope |
| What is the function of an additive in relation to obtaining blood samples? | To increase the rate of processing and general specimen quality |
| What is the majority of our plasma made out of? | Water |
| What is a buffy coat? | A [typically thin] band that contains WBCs and platelets |
| What may a thick buffy coat be an indication towards? | An illness developing in the body |
| Define an evacuated tube | This contains a vacuum with a rubber stopper that seals the tube. It also has sterile interiors to prevent contamination of the specimen and the patient |
| What is the benefit of the Hemogard Tubes? | They have a larger, plastic stopper to protect the technologist from aerosols that come out when removing the rubber stopper |
| Why is it important to not use tubes past their expiration date? | It is not a guarantee that the additives will work |
| What safety devices are required when collecting blood? | Proper PPE, safety needles, biohazard sharps containers |
| Why is "first morning" urine preferred for urine speciment collection? | It is the most concentrated due to it sitting in the bladder overnight |
| When should testing be performed if the urine specimen is refrigerated? | 6-8hrs |
| When should testing be performed if the urine specimen is stored at room temp? | Within 2hrs |
| Why may a random urine specimen collection (although the most common) be inaccurate at times? | The urine may be too diluted to analysis; it requires explicit instruction to the patient to prevent bodily contamination |
| What is one exception to the "first morning" urine specimen recommendation? | When testing for glucose in urine (void urine within 2-3hrs after a meal) |
| When is a "Mid-stream, clean catch" urine preferred and why? | For C&S (culture and sensitivity) testing; to reduce the incidence of cellular and microbial contamination |
| What steps are taken within a "Mid-stream, clean catch" to significantly diminish specimen contamination? | 1) Cleansing the urethral area 2) Voiding the first portion of urine into the toilet |
| When is a 24hr/timed urine specimen collection utilized? | When it's needed to determine accurate concentrations of various analytes (chemical substances) and calculated ratios |
| What is the difference between a Catheter Collection and a Suprapubic Aspiration Collection? | Catheter=utilizing a catheter on someone who is confined to a bed or cannot urinate independently Suprapubic Aspiration=utilizing needle aspiration (abdo to bladder on bedridden patients that cannot be catheterized or a sterile specimen is required. |
| What is necessary to prevent clotting for proper cell count analysis? | Heparin or EDTA anticoagulant |
| What would a sterile tube be used for? | Microbe culture analysis or Chemical analysis |
| What are the labeling requirements of any patient specimen? | LAST NAME, FIRST NAME DOB (or alternative patient identifier) DATE OF COLLECTION (DOC), TIME OF COLLECTION (TOC) TECHONOLOGIST INITIALS |
| What testing can be down with a urine specimen? | toxicology microbe culture analysis |
