The laboratory test results for a client with hemophilia will include which of the following?
1. Prolonged partial thromboplastin time (PTT)
2. INR (international normalized ratio) in the normal range
3. Normal prothrombin time (PT)
4. Normal bleeding time
Prolonged partial thromboplastin time (PTT)
Rationale: A PTT and INR are indicated for any patient suspected of having hemophilia. An increased or prolonged PTT is indicative of clotting factor deficiency or hemophilia. The INR time also would be increased beyond the normal range in accordance with the prolonged prothrombin time results. A normal PT and bleeding time are not indicative of a clotting factor disorder.
