Each chamber of the heart has a particular role in maintaining cellular oxygenation.
Which chamber is responsible for pumping blood to all the cells and tissues of the
body?
a. right ventricle
b. right atrium
c. left atrium
d. left ventricle
d. left ventricle
Rationale: The left ventricle pumps blood to all the cells and tissues in the body. The left
atrium receives oxygenated blood from the lungs. The right ventricle pumps blood from
the lungs to be oxygenated. The right atrium receives deoxygenated blood from the
venous system.
The nurse is assessing a client's pulse before outpatient diagnostic testing. What should
the nurse document when assessing the client's pulse?
a. Rate, quality and rhythm
b. Pressure, rate and rhythm
c. Quality, volume and rate
d. Rate, rhythm and volume
a. Rate, quality and rhythm
Rationale: Assess apical and radial pulses, noting rate, quality and rhythm. Pulse
pressure and volume are not assessed in this instance.
While the nurse is preparing a client for a cardiac catheterization, the client states that
they have a seafood allergy. Which of the following medication may the nurse give prior
to the procedure?
a. Methylprednisolone
b. Furosemide

, NSG 3000
c. Lorazepam
d. Phenytoin
a. Methylprednisolone
Rationale: Prior to cardiac catheterization, the patient is assessed for previous reactions
to contrast agents or allergies to iodine-containing substances, as some contrast agents
contain iodine. If allergic reactions are of concern, antihistamines or methylprednisolone
(Solu-Medrol) may be administered to the patient before angiography is performed.
Furosemide, Lorazepam and Phenytoin do not counteract
allergic reactions.
Which of the following is the primary pacemaker for the myocardium?
a. Atrioventricular junction
b. Bundle of His
c. Purkinje fibers
d. Sinoatrial node
d. Sinoatrial node
Rationale: The sinoatrial (SA) node is the primary pacemaker of the heart; the
atrioventricular (AV) node is the secondary pacemaker of the heart. Both are composed
of nodal cells.
The nurse is preparing a male patient to have a 12-lead ECG performed. When
prepping the skin the nurse notices that the patient has abundant chest hair. What is the
most appropriate nursing intervention to improve
adhesion of the ECG leads?
a. Use alcohol swabs to clean the skin before applying the leads
b. Clip the chest hair with the patient's permission before applying the
leads
c. Apply the leads to the arms and legs only
d. Reschedule the ECG
B. Clip the chest hair with the patient's permission before applying the leads
Rationale: Clipping the patient's hair would provide access to the skin to assist with
adhesion. Alcohol should not be used to prep the skin because it increases the skin's
electrical impedance, thereby hindering the detection of the cardiac electrical signal.
