The nurse is providing discharge instructions to a client who has had a permanent pacemaker inserted. The information in the chart indicates that the device is a DDD. What will the nurse explain about this pacemaker?

"A wire is in the left ventricle and will pace when needed."

"There are pacemaker wires in the right atrium and ventricle and will pace as needed."

"The wires are in both ventricles and fires when your heart rate is 50.

"The device is set to fire with each heart beat."

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

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.

A. Increased respiratory race B. Increased temperature C. Increased heart rate D. Increased blood pressure E. Increase hematocrit

Correct Answer is ["A","C","D"]

Explanation

A. Increased respiratory rate - Fluid overload can lead to pulmonary edema, which causes difficulty breathing and an increased respiratory rate.
B. Increased temperature - Fluid overload does not typically cause a temperature increase. A fever may indicate infection rather than fluid overload.
C. Increased heart rate - The body compensates for fluid overload by increasing the heart rate to maintain cardiac output.
D. Increased blood pressure - Fluid overload leads to increased blood volume, which results in elevated blood pressure.
E. Increase hematocrit - Hematocrit usually decreases with fluid overload, as it is diluted by the extra fluid volume.
