1Pressure cuff inflation setting used in the Ivy method bleeding time test is
Sphygmomanometer inflated to 40 mmHg
2Skin cleansing procedure and drying method for Ivy method bleeding time are
Cleanse area approximately three finger-widths below bend of elbow on volar surface with 70% alcohol and wipe dry with sterile gauze
3Incision dimensions required for the Ivy method bleeding time test are
2 skin incisions 2 mm deep and 2 mm long
4Blotting frequency and filter paper precaution for Ivy method bleeding time are
Blot drop of blood from each puncture site on 2 separate filter papers every 30 secs without touching filter paper to the wound
5Reporting method for the final result in Ivy method bleeding time is
Record bleeding times of the 2 puncture sites and report the average of the 2 results
6Normal reference value range for Ivy method bleeding time is
1 to 7 mins.
7Modification origins of Template Bleeding Time are
Modification by C.H. Mielke, Jr. and colleagues of the original Ivy bleeding time test
8Standardized device component used in Template Bleeding Time to replace original manual slits is
Used a template containing a standardized slit in place of the disposable lancets
9Commercially made device examples replacing template slits in bleeding time testing are
Simplate and Surgicutt
10General reference value range for Template Bleeding Time is
2 to 9 mins.
11Classification of Rumple-Leede Test as a clinical assessment is
An example of a capillary fragility test (particularly a tourniquet test)
12Initial step prior to applying pressure cuff in Rumple-Leede Test is
Determine the patient's blood pressure
13Inflation pressure level used during the Rumple-Leede Test procedure is
Inflate to a pressure midway systolic and diastolic
14Duration specified for maintaining pressure cuff inflation in Rumple-Leede Test is
Maintain this pressure for 5 minutes
15Time elapsed after cuff release before selecting petechiae counting area in Rumple-Leede Test is
15 minutes after release of pressure cuff
16Area dimensions selected for petechiae counting in Rumple-Leede Test are
Choose an area of 1-inch diameter anywhere on volar surface of arm or dorsal area of hands/fingers
17Normal value grade and abnormal indication threshold for Rumple-Leede Test are
Grade 1+ (a grade of 2+ and above is indicative of capillary weakness)
18Definition and role of thrombosthenin in clot retraction are
A contractile protein important for clot retraction
19Basic physiological principle of clot retraction measurement is
Normal blood clot contracts (expressing serum) and degree of clot retraction is measured on the amount of expressed serum
20Four essential factors required for normal blood clot retraction are
Normal level of fibrinogen, normal level of functioning platelets, calcium, and ATP
21Procedural indicator for stopping timer in Hirschboeck / Castor Oil Method is
Stop timer as soon as "dimpling" (droplet-like serum extrusion) on top portion of blood drop is detected
22Normal value range for Hirschboeck / Castor Oil Method clot retraction time is
15 to 45 mins.
23Diagnostic condition indicated by dark yellow extruded serum in Hirschboeck method is
Jaundice
24Diagnostic condition indicated by cloudy extruded serum in Hirschboeck method is
Plasma cell myeloma
25Diagnostic conditions indicated by milky extruded serum in Hirschboeck method are
Diabetes, leukemia, after meals
26Fresh venous blood volume placed into calibrated tube in Mac Farlane Method is
5 mL of fresh venous blood
27Coagulation incubation temperature and observation interval in Mac Farlane Method are
Place tube in 37 C water bath and observe every 5 to 10 minutes for coagulation
28Standing time and temperature required after firm clotting in Mac Farlane Method are
Allow tube to stand at room temperature for one hour
29Mathematical formula used to compute percentage clot retraction (%CR) in Mac Farlane Method is
%CR = (AMT. OF SERUM LEFT IN TUBE / AMT. OF BLOOD USED) X 100
30Normal reference value range for Mac Farlane Method clot retraction is
44 to 67%
