After a client has had a ventricular pacemaker
inserted, which point on the rhythm strip shows a
pacemaker spike?
oA
oB
oC
oD
oB
· Pacemaker impulses are represented by a spike
(letter B), which should be followed by a QRS
complex. Letters A, C, and D do not indicate the
pacemaker spike.
,A beta blocker is prescribed for the client with
persistent ventricular tachycardia. Which response
indicates that the beta blocker is working
effectively?
o Decreased anxiety
o Reduced chest pain
o Decreased heart rate
o Increased blood pressure
o Decreased heart rate
· A decreased heart rate is the expected response
to a beta blocker. Beta blockers inhibit the activity
of the sympathetic nervous system and of
,adrenergic hormones, decreasing the heart rate,
conduction velocity, and workload of the heart. A
beta blocker is not an anxiolytic and does not
reduce anxiety. A beta blocker is not an analgesic
and does not reduce chest pain. Beta blockers
reduce blood pressure.
A child being treated with cardiac medications
developed vomiting, bradycardia, anorexia, and
dysrhythmias. The nurse understands which
medication toxicity is responsible for these
symptoms?
o Digoxin
o Nesiritide
o Dobutamine
o Spironolactone
o Digoxin
· Digoxin helps improve pumping efficacy of the
heart, but an overdose can cause toxicity leading
to nausea, vomiting, bradycardia, anorexia, and
dysrhythmias. The side effects of nesiritide may
include effects such as headache, insomnia, and
hypotension. Dobutamine does not cause nausea
or vomiting but may cause hypertension and
hypotension. Spironolactone may cause edema.
, A client with a diagnosis of myocardial infarction
asks the nurse, "What is causing the pain I am
having?" Which explanation would the nurse give?
o Compression of the heart muscle
o Release of myocardial isoenzymes
o Rapid vasodilation of the coronary arteries
o Inadequate oxygenation of the myocardium
o Inadequate oxygenation of the myocardium
· Cessation of the blood flow that normally carries
oxygen to the myocardium results in pain because
of ischemia of myocardial tissue. Myocardial
infarction does not involve compression of the
heart. The release of myocardial isoenzymes is an
indication of myocardial damage; this does not
cause myocardial pain. Vasodilation will increase
perfusion and contribute to pain relief, not cause
myocardial pain.
The health care provider prescribes atenolol for a
client with angina. Which potential side effect will
the nurse mention when instructing the client
about this medication?
o Headache
