The nurse is caring for a client who received a transfusion of Fresh Frozen Plasma (FFP) for an acute GI bleed related to accidental wantarin overdose. Which laboratory result would indicate the need for an additional unit of Fresh Frozen Plasma (FFP) to correct the problem caused by the overdose?
INR = 3.7 (normal 0.9-1.1)
Hemoglobin = 6.3g/dL (normal Female: 11.7-15.5 g/dL: Male: 14-17:3 g/dL)
Fibrinogen = 90mg/dL (normal 200-400mg/dL)
Platelets = 101,000 mm3 (normal 150,000-450,000 mm3)
The Correct Answer is A
A. INR = 3.7: The International Normalized Ratio (INR) is a measure of blood clotting. An INR greater than
3.0 indicates that the blood is not clotting properly, which can be caused by warfarin overdose. An elevated INR requires FFP to correct coagulopathy.
B. Hemoglobin = 6.3g/dL: This is low, indicating anemia, but it is not directly related to warfarin overdose. The primary issue here is coagulopathy, not anemia.
C. Fibrinogen = 90mg/dL: Fibrinogen levels may be decreased in various conditions, but this alone does not necessarily require additional FFP unless it’s below a critical threshold. Fibrinogen is not the main marker for warfarin overdose.
D. Platelets = 101,000 mm3: This platelet count is within the lower end of the normal range but does not indicate that more FFP is needed in response to warfarin overdose.

Correct Answer is B
Explanation
A. Serum sodium level of 135 mEq/L (normal 135-145mEq/L) - Although important, sodium levels do not directly assess the effectiveness of furosemide in relieving fluid overload.
B. Respiratory rate of 16/minute - A decrease in respiratory rate following the administration of furosemide indicates that the client is improving, as furosemide works to reduce fluid overload and ease breathing.
C. Blood pressure reading of 120/80 - While blood pressure may be influenced by fluid status, it is not the best indicator for the effectiveness of diuretics in this case.
D. Urine output 120 mL one hour following administration - While urine output is important, a single hour’s output may not show the full effectiveness of the diuretic, and output can vary depending on the client’s hydration status.
Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"C"}
Explanation
Ventricular fibrillation (VF) is characterized by a chaotic, rapid, and irregular electrical activity on the ECG, with no identifiable QRS complexes, P waves, or T waves. The heart quivers ineffectively, leading to no blood flow or cardiac output, which results in rapid loss of consciousness and is life-threatening.
Immediate defibrillation is required to restore a normal rhythm. A high-energy shock is delivered to the heart to reset the electrical activity, potentially allowing the heart's natural pacemaker to regain control and resume normal function.
