The oncoming nurse sees that the patient is receiving IV heparin at 7 mL/hr. The concentration of the heparin is 50,000 units in 250 ml of saline. The patient is ordered 1600 units of heparin per hour. The lab calls the oncoming nurse with the result of the patient's activated partial prothrombin time (aPTT) is 37 seconds. What actions will the oncoming nurse take? (SELECT ALL THAT APPLY)

A.    The nurse should notify the prescriber about the current dose (7 mL/hr) because the patient is ordered 1600 units of heparin per hour. The current infusion rate needs to be assessed in relation to the aPTT result, especially if the aPTT indicates that the patient may be at risk for bleeding.
B.    While having a second IV may be useful for administering fluids or medications in case of a bleeding emergency, there is no immediate indication for IV 0.9 saline in this scenario. The priority is to assess the heparin dosage and aPTT before making additional IV arrangements.
C.    It’s important to assess the IV site for signs of infiltration, especially since the patient is on heparin therapy. Infiltration can affect the effectiveness of the medication and cause complications, so this assessment is vital.
D.    While it is important to verify lab results, the nurse should primarily focus on addressing the current situation regarding the heparin infusion and the patient’s anticoagulation status rather than confirming lab results with the lab technician at this moment.
E.    While protamine sulfate is an antidote to heparin, it is not warranted based solely on the aPTT result of 37 seconds. The normal aPTT range is typically around 30-40 seconds, depending on the laboratory standards, and the aPTT may not indicate that the patient requires reversal of heparin at this time.
