1. What term is defined as the volume of blood ejected by the heart in 1 minute?
a. Afterload
b. Cardiac cycle
c. Stroke volume
d. Cardiac output
ANS: D
h a
Ta
Cardiac output is defined as the volume of blood ejected by the heart in 1 minute. Cardiac output
= Heart rate x Stroke volume. Afterload is the resistance against which the ventricles must pump
when ejecting blood (ventricular ejection). A cardiac cycle is the sequential contraction and
relaxation of both the atria and ventricles. Stroke volume is the amount of blood ejected by the
b
heart in any one contraction.

2. A chest radiography examination is ordered for a child with suspected cardiac problems. The
childs parent asks the nurse, What will the x-ray show about the heart? The nurses response
should be based on knowledge that the radiograph provides which information?
H
a. Shows bones of the chest but not the heart
b. Evaluates the vascular anatomy outside of the heart
c. Shows a graphic measure of electrical activity of the heart
d. Supplies information on heart size and pulmonary blood flow patterns
ANS: D
Chest radiographs provide information on the size of the heart and pulmonary blood flow
patterns. The bones of the chest are visible on chest radiographs, but the heart and blood vessels
are also seen. Magnetic resonance imaging is a noninvasive technique that allows for evaluation
,of vascular anatomy outside of the heart. A graphic measure of electrical activity of the heart is
provided by electrocardiography.

3. A 6-year-old child is scheduled for a cardiac catheterization. What consideration is most
a
important in planning preoperative teaching?
h
a. Preoperative teaching should be directed at his parents because he is too young to
understand.
Ta
b. Preoperative teaching should be adapted to his level of development so that he
can understand.
c. Preoperative teaching should be done several days before the procedure so he will
be prepared.
b
d. Preoperative teaching should provide details about the actual procedures so he
will know what to expect.
ANS: B
e e
Preoperative teaching should always be directed to the childs stage of development. The
a b
caregivers also benefit from these explanations. The parents may ask additional questions, which
should be answered, but the child needs to receive the information based on developmental level.
This age group will not understand in-depth descriptions. School-age children should be
H
prepared close to the time of the cardiac catheterization.

4. After returning from cardiac catheterization, the nurse monitors the childs vital signs. The
heart rate should be counted for how many seconds?
a. 15
, b. 30
c. 60
d. 120
ANS: C
The heart rate is counted for a full minute to determine whether arrhythmias or bradycardia is
present. Fifteen to 30 seconds are too short for accurate assessment. Sixty seconds is sufficient to
assess heart rate and rhythm.

5. After returning from cardiac catheterization, the nurse determines that the pulse distal to the
catheter insertion site is weaker. How should the nurse respond?
a. Elevate the affected extremity.
b. Notify the practitioner of the observation.
e b
b e
c. Record data on the assessment flow record.
d. Apply warm compresses to the insertion site.
ANS: C
H a
The pulse distal to the catheterization site may be weaker for the first few hours after
catheterization but should gradually increase in strength. Documentation of the finding provides
a baseline. The extremity is maintained straight for 4 to 6 hours. This is an expected change. The
pulse is monitored. If there are neurovascular changes in the extremity, the practitioner is
notified. The site is kept dry. Warm compresses are not indicated.
