The nurse checks the results of the partial thromboplastin time (PTT) of a client who has been receiving a daily subcutaneous dose of heparin. The client’s PTT is 100 seconds; the normal PTT value is 60 to 70 seconds. Which of the following can the nurse expect when the PTT lab result is reported to the physician?

1. The physician will order the same daily dose of heparin because the client’s PTT level is within a therapeutic range.

2. The physician will order a higher dose of heparin because the client is not adequately anticoagulated.

3. The physician will order to withhold today’s dose of heparin because the client’s ability to clot is dangerously impaired.

4. The physician will order protamine sulfate to counteract the effect of the heparin.
