vasodilation.
9. The nurse has read that the cardiologist recommends the use of class IV
drugs to depress sinus and atrioventricular node conduction and
terminate supraventricular tachycardias in the patient at this time. The
nurse will antic- ipate orders for which medications (Answer) a.

10.The nurse has administered a drug that stimulates ²1-adrenergic sites.
,Following administration of the drug, the nurse will assess for (Answer) a.
increased heart rate.
11.The nurse is observing the patient's electrocardiographic monitor
after insertion of a temporary pacemaker. Seeing a P-wave after the
pacing arti- fact, the nurse knows that the (Answer) c. atrium is being
paced.
12.The possibility of microshock when handling a temporary pacemaker
can be minimized by (Answer) b. insulating the ends of the wires. and
wearing gloves when handling the pacing wires
13.In the postoperative cardiovascular patient, the most frequent cause of
a decreased cardiac output is (Answer) a. reduced preload.
, 14.A patient is being monitored by continuous electrocardiogram (ECG)
after placement of a transvenous pacemaker. "Loss of capture" is seen on
the ECG. Which nursing intervention may correct this situation (Answer)
a. Position the patient on the left side. or reposition the leads
15.In analyzing the ECG strip, the nurse notices a spike before each QRS
complex. The patient's heart rate is 70 beats/min. This phenomenon is
reflec- tive of: b. pacing artifact; the pacemaker is sensing and
capturing.
