BLEEDING TIME; COAGULATION TIME

Question 1

______ is a laboratory test that measures how long it takes for a small cut to stop bleeding. It is important for assessing platelet function, which is vital for blood clotting. Prolonged bleeding time can indicate bleeding disorders, monitor medication effects, evaluate surgical risk, and assess platelet function.

Answer 1

Bleeding time

Question 2

______ is a laboratory test that measures how long it takes for blood to clot. It is crucial for assessing the overall blood clotting process. Prolonged coagulation time can indicate clotting disorders, monitor anticoagulant therapy, evaluate surgical risk, and assess liver function.

Answer 2

Coagulation time

Question 3

______ (______) - This is a test for capillary contractility. This test measures the time required for bleeding to stop after a standardized stab wound.

Answer 3

Bleeding Time, Duke’s Method

Question 4

The determination of the ______ is considered as one of the most important procedures used in the detection and differential diagnosis of hemorrhagic diseases.

Answer 4

bleeding time

Question 5

With the use of the Duke’s method, the normal range of bleeding time is ______ to ______ minutes. This result is influenced by:

a. ______
b. ______
c. ______
d. ______

Answer 5

2, 5

size and shape of the instrument
force applied in setting the injury
depth of the structure
location, texture, and vascularity of the area selected

Question 6

Advantages of the earlobe for bleeding time:

Answer 6

a. The skin of the ear is thin.
b. The subcutaneous tissue is quite vascular.

Question 7

Disadvantages of the earlobe for bleeding time:

Answer 7

a. The earlobe site is less convenient than the forearm.
b. It does not allow control tests.
c. It does not involve the stress of increased vascular pressure.

Question 8

Interpretation of results for bleeding time:

PROLONGED

Answer 8

indicative of systemic vascular disorders and thrombocytopenic perpuras

Question 9

Interpretation of results for bleeding time:

NORMAL

Answer 9

may be found also in cases of AHG, PTC, and PTA deficiencies

Question 10

Interpretation of results for bleeding time:

SHORT

Answer 10

indicative of normal hemostatic mechanisms

Question 11

The interval of time between the collection of blood and the appearance of fibrin is the ______.

Answer 11

coagulation time

Question 12

______ - This procedure tests the composite action of all plasma factors acting simultaneously.

Answer 12

COAGULATION TIME

Question 13

The normal coagulation time with the use of the capillary tube method ranges from ______ to ______ minutes. This value is increased in any disease in which there is an absence of/or very small amounts of the essential coagulation components; also in fibrinolytic diseases and conditions with increase in inhibitor factors.

Answer 13

one, five

Question 14

In skin ______, tissue and blood vessels play an important part in stopping flow of blood; whereas in ______, there is no blood vessel factor and tissue actor is minimal.

Answer 14

bleeding time, coagulation time

Question 15

In skin ______, the character of the clot is all important, for a feeble, poorly adherent and non-retractile clot is incapable of closing the wound adequately and is swept away by flowing blood as fast as it is formed. In ______, the strength of the clot and its ability to retract or not involved.

Answer 15

bleeding time, coagulation time

Question 16

______ can be affected by platelet disorders, blood vessel disorders, medications, age, and other factors like liver disease or vitamin K deficiency. These factors can impact the number of function of platelets, the ability of blood vessels to constrict, or interfere with the clotting process.

Answer 16

Bleeding time

Question 17

______ can be affected by a variety of factors that influence the body’s ability to form blood clots. Inherited clotting disorders, liver disease, and vitamin K deficiency can all disrupt the clotting process. Medications like anticoagulants and antiplatelet drugs are designed to slow down clotting. Other factors like severe infections, certain autoimmune diseases, kidney disease, and age can also influence this.

Answer 17

Coagulation time

Question 18

______ holds physiological significance by providing insights into the body’s primary hemostatic mechanisms, namely platelet function and vascular integrity. It reflects the ability of platelets to adhere to injured blood vessels and form a platelet plug, the initial step in hemostasis.

Answer 18

Bleeding time

Question 19

______ holds significant physiological significance as it reflects the overall efficiency of the complex clotting cascade, a vital process for maintaining hemostasis and preventing excessive bleeding.

Answer 19

Coagulation time
