NCLEX Practice Question of the Week

leave a comment »

Here is the weekly question posted on the NCSBN Learning Extension:

Prior to administration of Alteplase (TPA) to a client admitted with a diagnosis of cerebral vascular accient (CVA), which serum lab value should a nurse check?

  1. Arterial blood gasses and complete blood count
  2. Potassium and magnesium
  3. Blood urea nitrogen and creatinine
  4. Prothrombin time and partial Prothrombin time

The correct answer is 4-Prothrombin time and partial Prothrombin time.

Alteplase (Activase, Cathflo Activase) is a thrombolytic drug. A cerebral vascular accident (CVA) occurs when a portion of the brain is deprived of oxygen and dies. The loss of oxygen can be due to a blockage of rupture. PT and PTT lab values would determine if the CVA was from a clot of rupture, and if it was a clot, the Alteplase would be used to dissolve the blood clot.
