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)

Answer and Explanation

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. The pacemaker wire for a DDD device is placed in the right atrium and right ventricle, not the left ventricle.
B. This is the correct description of a DDD pacemaker, which has wires in both the right atrium and right ventricle to monitor and pace both chambers when needed.
C. This is incorrect because a DDD pacemaker does not pace both ventricles.
D. This is inaccurate because a DDD pacemaker does not fire with every heartbeat; it only fires when the heart’s natural electrical activity is insufficient.

A. Second degree AV block- Mobitz II B. Sinus bradycardia with first degree AV block C. Second degree AV block- Mobitz I D. Third degree heart block

Correct Answer is C

Explanation

A. Mobitz II is a type of second-degree AV block characterized by constant PR intervals and sudden dropped QRS complexes (i.e., the PR interval does not lengthen progressively). This is a more serious block because the dropped beats are unpredictable and could lead to complete block.
B. Sinus bradycardia is a slower-than-normal heart rate (usually less than 60 beats per minute) that originates from the sinus node. First-degree AV block is characterized by a prolonged PR interval, but unlike second-degree block, there are no dropped QRS complexes.
C. Mobitz I (Wenckebach) is a second-degree AV block where the PR interval gradually lengthens with each successive beat until a QRS complex is dropped. After the dropped beat, the cycle repeats. This is a relatively benign block and often resolves without intervention, though it requires monitoring.
D. Third-degree heart block (also known as complete heart block) occurs when there is no communication between the atria and ventricles. The atria and ventricles beat independently of each other. There are no relationship between the P waves and QRS complexes, and the ventricular rate is typically slower than the atrial rate.
