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. A decreased D-dimer level is a positive outcome, as D-dimer is elevated in DIC due to the formation of clots and the breakdown of fibrin. Lower levels indicate less clot formation and better control of the condition.
B. Fibrinogen levels are typically low in DIC due to consumption of clotting factors. Elevated fibrinogen in this case would be a negative indicator, suggesting that clotting is not resolving.
C. A decreased platelet count is a hallmark of DIC and indicates ongoing consumption of platelets due to widespread clotting. A decrease would not be a positive outcome.
D. A prolonged PT is another indicator of DIC, suggesting impaired clotting function. This is not a positive outcome.

A. Administer timolol eye drops to both eyes B. Insert an indwelling catheter C. Administer an antidiarrheal medication D. Provide frequent oral care

Correct Answer is D

Explanation

A. Timolol eye drops are not indicated following the administration of atropine, as atropine has no effect on intraocular pressure.
B. Inserting an indwelling catheter is not necessary for the administration of atropine, which is used to treat bradycardia, not urinary retention.
C. Administering an antidiarrheal medication is unrelated to atropine administration; atropine typically causes dry mouth rather than diarrhea.
D. Atropine is an anticholinergic medication that decreases saliva production, which can lead to dry mouth and discomfort. Frequent oral care is important to prevent oral mucosal irritation and discomfort for the client.
