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 D
Explanation
A. This type of AV block is characterized by a progressively lengthening PR interval until a QRS complex is dropped (a blocked beat). A PR interval of 0.28 seconds could be seen in 2nd degree Mobitz I (Wenckebach), not Mobitz II, which has a more irregular pattern of dropped beats
B. Atrial flutter: Atrial flutter is a type of arrhythmia characterized by rapid atrial rates (typically around 250-350 beats per minute) with a sawtooth pattern of P-waves. It does not relate to the PR interval, but rather the atrial rhythm.
C. Sinus bradycardia: Sinus bradycardia is characterized by a slower-than-normal heart rate (less than 60 beats per minute), but this does not affect the PR interval directly. A normal PR interval (0.12-0.20 seconds) can still be seen in sinus bradycardia, so the prolonged PR interval in this case makes sinus bradycardia less likely.
D. 1st degree AV block: In 1st degree AV block, the PR interval is consistently prolonged, usually more than 0.20 seconds, but it is still a constant, non-variable delay in the conduction between the atria and ventricles. A PR interval of 0.28 seconds (which is longer than normal but consistent) is characteristic of a first-degree AV block, making it the correct answer.
Correct Answer is A
Explanation
A. Petechiae (small, pinpoint hemorrhages) are a common manifestation of DIC due to the excessive clotting and subsequent breakdown of clotting factors, leading to bleeding into the skin.
B. Diarrhea is not typically a primary symptom of DIC, although gastrointestinal bleeding can occur in severe cases.
C. Intractable vomiting is not characteristic of DIC, although it could occur in clients with severe bleeding or complications.
D. Urinary incontinence is not a direct manifestation of DIC, although it could occur secondary to neurological or other systemic complications.
