AACN Cardiac Medicine Subspecialty Certification Adult - Additional Info Sample Questions

Which of the following will NOT effect PTT?

Correct Answer:
acetaminophen.


the partial thromboplastin time (ptt) test is used to assess the blood’s ability to form clots appropriately. it mainly evaluates the function of various factors that are part of the intrinsic and common pathways of the coagulation cascade. factors involved in these pathways include factor viii, ix, xi, and xii, among others. ptt can be influenced by various substances, conditions, and deficiencies that impact these clotting factors.

coumadin (warfarin) is a well-known anticoagulant medication that affects the clotting process by inhibiting the synthesis of vitamin k-dependent clotting factors, which include factors ii, vii, ix, and x. while these factors are more directly assessed by the prothrombin time (pt) and inr tests, coumadin can also indirectly prolong the ptt by reducing the overall clotting capability of the blood.

vitamin k deficiency affects the body’s ability to produce the vitamin k-dependent clotting factors (ii, vii, ix, and x), similar to the effect seen with coumadin use. although the primary tests impacted by vitamin k levels are pt and inr, severe deficiencies can also extend the ptt due to the broad impact on clotting factor synthesis.

hemophilia is a genetic disorder that directly impacts the intrinsic pathway of the clotting cascade, specifically factors viii and ix, depending on the type (hemophilia a or b, respectively). individuals with hemophilia have a significantly prolonged ptt because their blood lacks sufficient functional clotting factor to form a clot properly during the test.

acetaminophen, commonly known as tylenol, is a pain reliever and a fever reducer. it works by inhibiting the synthesis of prostaglandins in the central nervous system and through a peripheral action by blocking pain impulse generation. significantly, it does not affect the clotting factors or the coagulation cascade. therefore, acetaminophen will not affect the ptt, making it distinctly different in action from the other substances and conditions listed, which all have a direct or indirect impact on blood coagulation factors and pathways.
