A patient is to receive a continuous infusion of Diltiazem at 2.5 mg hr for Atrial fibrillation, The medication is supplied 125 mg of Diltlazem in 125 mL of IV fluid. At what rate should the nurse set the IV pump? (round to the nearest tenth)

A) Prolonged prothrombin time (PT):
A prolonged PT is a sign of impaired coagulation, which is common in DIC as the clotting factors are consumed. In DIC, both clotting and bleeding occur, leading to prolonged PT. Therefore, a prolonged PT does not reflect a positive outcome. A positive outcome would show normalization or improvement of the clotting profile.

B) Elevated fibrinogen level:
Fibrinogen is often decreased in DIC because it is consumed in the process of forming clots. An elevated fibrinogen level would not indicate a positive outcome in DIC. Instead, fibrinogen levels typically fall in DIC due to widespread clotting activity. A positive outcome would involve a normalization or increase in fibrinogen levels as the condition improves.

C) Decreased platelet count:
Platelet count typically decreases in DIC because platelets are used up in the formation of clots, leading to thrombocytopenia. A decreased platelet count reflects ongoing consumption of platelets and would not be a positive indicator of improvement. In a positive outcome, the platelet count would increase toward normal levels.

D) Decreased D-dimer level:
D-dimer is a product of fibrin degradation and is elevated in conditions like DIC, where abnormal clotting and fibrinolysis are occurring. A decreased D-dimer level indicates that the coagulation process is resolving, and fibrin degradation is returning to normal, reflecting a positive outcome. Monitoring the D-dimer level is a key indicator of improvement in DIC.

A) Dyspnea, crackles, hypertension, and edema:
These symptoms suggest a transfusion-related acute lung injury (TRALI) or circulatory overload (TACO), both of which are potentially life-threatening conditions. In cases of TRALI or TACO, the nurse should stop the transfusion immediately but should NOT administer 0.9% normal saline because saline could exacerbate fluid overload and worsen pulmonary edema. Instead, the nurse should focus on managing respiratory distress, ensuring proper oxygenation, and notifying the healthcare provider for further intervention.

B) Low back pain, hypotension, and tachycardia:
These symptoms are typically indicative of a hemolytic transfusion reaction (HTR), which requires immediate intervention. In this case, the transfusion should be stopped immediately, but the nurse should begin administering 0.9% normal saline to help maintain the patient's blood pressure and promote kidney perfusion to prevent renal damage.

C) Urticaria, itching, wheezing, angioedema:
These symptoms are characteristic of a mild allergic reaction to the blood transfusion. In this case, the nurse should stop the transfusion and administer 0.9% normal saline to maintain the patient’s hydration and blood pressure while managing the allergic reaction. The healthcare provider may order antihistamines or corticosteroids to treat the allergic symptoms.

D) Chest tightness, fever, chills/rigors:
These are common symptoms of a febrile non-hemolytic transfusion reaction (FNHTR), which is generally not life-threatening. The nurse should stop the transfusion but can continue administering 0.9% normal saline to support hydration and circulation. FNHTR is often managed with antipyretics (e.g., acetaminophen) to reduce fever and chills, and the transfusion may be resumed if symptoms resolve
