Answer 1:

Bleeding time test is used for assessment of patients' platelets function that is coagulation. In this test, an incision is made on the forearm on area where there is no hair or any veins. This incision is of standard width and depth and done with an automatic device. Subsequently, it bleeds. When it stops bleeding it is the indication of a platelet plug, the bleeding time is noted.

This test is performed when less invasive and more reliable tests like PT (Prothrombin Time) and PTT (Partial Thromboplastin time) are not available. However, it is reliable in case of an assessment of clinical bleeding in uremia patients. When the skin is invaded, there are chances of excessive bleeding which may lead to infection.

PT and PTT are generally used for the evaluation of coagulation disorders. PT determines the extrinsic system integrity and factors present in both extrinsic and intrinsic systems. PTT determines intrinsic system integrity and its common factors.

An IE performed a time study on a hydraulic valve installation & test process. Each observed installation was performed by a different production worker, so the activity factor (performance rating) varied in each observation. A factor > 1.00 meant the worker was performing better than normal in their observed time (OT) (i.e, faster), while a factor < 1.00 meant the worker was performing less normal in their observed time (OT) (ie, slower). The allowance for personal delay and fatigue as...
