What could/should the nurses have done when there as no lab testing performed

  If there was a situation where no lab testing was performed on a patient receiving coagulation therapy, the nurses should take the following steps:

Communicate with the healthcare team: The nurses should inform the healthcare team, including the prescribing physician, about the lack of lab testing. Effective communication is crucial to ensure patient safety. 

Document the situation: Proper documentation of the circumstances, including the reasons for the lack of lab testing, should be recorded in the patient's medical chart. This documentation can help in future decision-making and patient care.

Request lab testing: The nurses can request the necessary lab tests to monitor the patient's coagulation status. This may involve drawing blood for tests such as PT (Prothrombin Time), INR (International Normalized Ratio), and APTT (Activated Partial Thromboplastin Time).
