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 D

Explanation

A. A value of 119 seconds would indicate a therapeutic or even elevated level of heparin, as it is much higher than the normal aPTT range.
B. A value of 98 seconds is still above the normal aPTT range, suggesting that the heparin level is therapeutic, or even too high, but not sub-therapeutic.
C. This is just slightly above the normal range and might be considered a therapeutic range for someone
on heparin, but it’s not sub-therapeutic.
D. This aPTT value is above the normal range but likely not high enough to indicate therapeutic heparin levels, which should typically be between 1.5 to 2.5 times the normal aPTT. A sub-therapeutic level could be indicated with a lower value.

A. Report the findings and anticipate a medical prescription for amiodarone B. Initiate a rapid response call and increase the monitor's sensitivity C. Start compressions and prepare for defibrillation D. Establish unresponsiveness and check the carotid pulse

Correct Answer is D

Explanation

A. Reporting the findings and anticipating a prescription for amiodarone may be necessary later, but the first step is to assess the patient's immediate condition (unresponsiveness, pulse status, etc.).
B. Although increasing monitor sensitivity and initiating a rapid response call might be helpful, these actions come after assessing the patient’s condition. If the patient is in distress or unresponsive, the nurse needs to check for a pulse and intervene right away.
C. This is a crucial action if the patient is unresponsive and pulseless (cardiac arrest). If the patient is found to be unresponsive and pulseless, starting chest compressions immediately and preparing for defibrillation is the next step. However, the first action is to check for pulse and responsiveness.
Why it's incorrect: Compressions and defibrillation are correct actions if the patient is pulseless, but before taking these steps, the nurse must assess the patient for responsiveness and check the carotid pulse. Starting CPR and preparing defibrillation without verifying the patient's condition could delay appropriate care.
D. Checking responsiveness and pulse is the most immediate and critical action because VT may be asymptomatic or cause deterioration, including cardiac arrest. Once pulse and responsiveness are determined, appropriate interventions (such as defibrillation or CPR) can be initiated quickly.
