EAQ- NUR 320 (2) Cardiac | Questions with 100% Verified
Answers | Latest Update
Question:
The electrocardiogram (ECG) of a patient indicates P waves that are hidden in the preceding T
waves and normal QRS complexes. The nurse recognizes that the patient is experiencing what
condition? Ventricular fibrillation Junctional dysrhythmia Premature atrial contractions Premature
ventricular contractions
Answer:
Premature atrial contractions
Question:
Cardiac biomarker levels are being evaluated for a patient who is suspected of having a myocardial
infarction (MI). The nurse recognizes that which biomarker lacks specificity and that its role in
diagnosing an MI is limited? Myoglobin Creatine kinase-MB (CKMB) Cardiac-specific troponin I (cTnI)
Cardiac-specific troponin T (cTnT)
Answer:
Myglobin ***Myoglobin is a serum cardiac marker that is released into the circulation within two
hours after a myocardial infarction (MI). Myoglobin's role in diagnosing MI is limited because it lacks
cardiac specificity. Creatine kinase-MB (CKMB) levels begin to rise about six hours after an MI, are
specific to myocardial cells, and help quantify myocardial damage. Cardiac-specific troponin T
(cTnT) and cardiac-specific troponin I (cTnI) are highly specific indicators of MI.
Question:
A patient with chest pain experiences a heart rate of 200 beats/minute and blood pressure of 80/50
mm Hg. The electrocardiogram shows absent P waves. The nurse expects that which intravenous
medication will be prescribed? Digoxin Atropine Adenosine Vasopressin
Answer:
Adenosine
Question:
The nurse that is monitoring the electrocardiogram (ECG) of a patient with hyperthyroidism
observes regular, sawtooth- shaped flutter waves with an atrial rate 250 beats/minute. How should
the nurse document this pattern? Sinus bradycardia Sinus tachycardia Atrial flutter Atrial fibrillation
Answer:
Atrial flutter
Question:
The nurse assesses a patient who has been administered the tissue-type plasminogen activator
alteplase for an acute myocardial infarction. Which assessment finding is the highest priority and
should be reported to the primary health care provider immediately Anorexia Hematuria Oral
temperature of 100.4° F (38° C) Occasional premature ventricular contractions
, Answer:
Hematuria
Question:
The nurse is caring for a patient one month after the patient's cardiac surgery. The patient is
hospitalized with a three-day history of chest pain, joint pain, and a body temperature of 101°F. The
patient's lab results include a white blood cell count of 15,000/mcL and an erythrocyte
sedimentation rate of 30 mm/hr. Which condition does the nurse suspect? Pneumonia Hiatal hernia
Dressler syndrome Ventricular aneurysm
Answer:
Dressler Syndrome ****Dressler syndrome is pericarditis that develops four to six weeks after
cardiac surgery. This syndrome is caused by an antigen-antibody reaction to the necrotic
myocardium, and the patient may experience pericardial pain, fever, and arthralgia. Laboratory
findings of an elevated white blood cell count and sedimentation rate also indicate Dressler
syndrome. Note that the normal level of white blood cells is 10,000/cc and the normal range of
sedimentation rate is 0 to 22 mm/hr for men and 0 to 29 mm/hr for women. Pneumonia and hiatal
hernia can cause chest pain that requires emergency management. Ventricular aneurysm results
from thinning of myocardial wall during contraction.
Question:
The nurse expects to assess what heart rate in a patient with paroxysmal supraventricular
tachycardia (PSVT)? Slower than 60 beats/minute Between 60 and 100 beats/minute Between 100
and 150 beats/minute Between 150 and 220 beats/minute
Answer:
Between 150 and 220 beats/minute
Question:
A patient experiences prolonged chest pain that is not immediately reversible. The patient's health
care provider explains that the cause of the pain is that a once-stable atherosclerotic plaque has
ruptured, causing platelet aggregation and thrombus formation. The nurse recognizes this meets
the definition of what diagnosis? Unstable angina Acute coronary syndrome (ACS) ST segment
elevation myocardial infarction (STEMI) Non-ST segment elevation myocardial infarction (NSTEMI)
Answer:
Acute coronary syndrome (ACS) ***When ischemia is prolonged and not immediately reversible,
ACS develops. ACS is associated with deterioration of a once stable atherosclerotic plaque that
ruptures, exposes the intima to blood, and stimulates platelet aggregation and local
vasoconstriction with thrombus formation. The unstable lesion, if partially occlusive, will be manifest
as unstable angina or NSTEMI. If there is total occlusion, it is manifest as STEMI.
