Cardiovascular Nclex Questions
With Accurate Answers
1) A client is scheduled for a cardiac catherization using a radiopaque
dye. Which of the following assessments is most critical before the
procedure?
Intake and output
Baseline peripheral pulse rates
Height and weight
Allergy to iodine or shellfish correct answer 4.
This procedure requires an informed consent because it involves
injection of a radiopaque dye into the blood vessel. The risk of allergic
reaction and possible anaphylaxis is serious and must be assessed
before the procedure.
10) A 60-year-old male client comes into the emergency department
with complaints of crushing chest pain that radiates to his shoulder and
left arm. The admitting diagnosis is acute myocardial infarction.
Immediate admission orders include oxygen by NC at 4L/minute, blood
work, chest x-ray, an ECG, and 2mg of morphine given intravenously.
The nurse should first:
Administer the morphine
Obtain a 12-lead ECG
,Obtain the lab work
Order the chest x-ray correct answer 1.
Although obtaining the ECG, chest x-ray, and blood work are all
important, the nurse's priority action would be to relieve the crushing
chest pain.
11) When administered a thrombolytic drug to the client experiencing
an MI, the nurse explains to him that the purpose of this drug is to:
Help keep him well hydrated
Dissolve clots he may have
Prevent kidney failure
Treat potential cardiac arrhythmias. correct answer 2.
Thrombolytic drugs are administered within the first 6 hours after onset
of a MI to lyse clots and reduce the extent of myocardial damage.
12) When interpreting an ECG, the nurse would keep in mind which of
the following about the P wave? Select all that apply.
Reflects electrical impulse beginning at the SA node
Indicated electrical impulse beginning at the AV node
Reflects atrial muscle depolarization
Identifies ventricular muscle depolarization
,Has duration of normally 0.11 seconds or less. correct answer 1, 3, 5.
In a client who has had an ECG, the P wave represents the activation of
the electrical impulse in the SA node, which is then transmitted to the
AV node. In addition, the P wave represents atrial muscle
depolarization, not ventricular depolarization. The normal duration of
the P wave is 0.11 seconds or less in duration and 2.5 mm or more in
height.
13) A client has driven himself to the ER. He is 50 years old, has a
history of hypertension, and informs the nurse that his father died of a
heart attack at 60 years of age. The client is presently complaining of
indigestion. The nurse connects him to an ECG monitor and begins
administering oxygen at 2 L/minute per NC. The nurse's next action
would be to:
Call for the doctor
Start an intravenous line
Obtain a portable chest radiograph
Draw blood for laboratory studies correct answer 2.
Advanced cardiac life support recommends that at least one or two
intravenous lines be inserted in one or both of the antecubital spaces.
Calling the physician, obtaining a portable chest radiograph, and
drawing blood are important but secondary to starting the intravenous
line.
, 14) The nurse receives emergency laboratory results for a client with
chest pain and immediately informs the physician. An increased
myoglobin level suggests which of the following?
Cancer
Hypertension
Liver disease
Myocardial infarction correct answer 4.
Detection of myoglobin is one diagnostic tool to determine whether
myocardial damage has occurred. Myoglobin is generally detected
about one hour after a heart attack is experienced and peaks within 4
to 6 hours after infarction (Remember, less than 90 mg/L is normal).
15) When teaching a client about propranolol hydrochloride, the nurse
should base the information on the knowledge that propranolol
hydrochloride:
Blocks beta-adrenergic stimulation and thus causes decreased heart
rate, myocardial contractility, and conduction.
Increases norepinephrine secretion and thus decreases blood pressure
and heart rate.
Is a potent arterial and venous vasodilator that reduces peripheral
vascular resistance and lowers blood pressure.
