Question 1 of 5
What term is defined as the volume of blood ejected by the heart in 1 minute?
Correct Answer: D
Rationale: Cardiac output is the volume of blood ejected by the heart per minute, calculated as heart rate times stroke volume. Afterload is resistance to ventricular ejection, cardiac cycle is the sequence of atrial and ventricular contraction, and stroke volume is the blood ejected per contraction.
Question 2 of 5
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?
Correct Answer: D
Rationale: Chest radiographs reveal heart size and pulmonary blood flow patterns, aiding in cardiac assessment. They also show chest bones, but the heart is visible. Vascular anatomy is evaluated via MRI, and electrical activity is measured by electrocardiography, not radiographs.
Question 3 of 5
A 6-year-old child is scheduled for a cardiac catheterization. What consideration is most important in planning preoperative teaching?
Correct Answer: B
Rationale: Teaching adapted to a 6-year-old?s developmental level ensures understanding and reduces anxiety. Parents benefit but the child needs tailored explanations. Detailed procedures are too complex for this age, and teaching close to the procedure time is sufficient.
Question 4 of 5
After returning from cardiac catheterization, the nurse monitors the childs vital signs. The heart rate should be counted for how many seconds?
Correct Answer: C
Rationale: Counting the heart rate for 60 seconds ensures accurate detection of arrhythmias or bradycardia. Shorter durations (15 or 30 seconds) are insufficient, and 120 seconds is unnecessarily long for routine assessment.
Question 5 of 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?
Correct Answer: C
Rationale: A weaker pulse post-catheterization is expected initially and should be documented as a baseline for monitoring. The pulse should strengthen over hours. Elevation, warm compresses, or immediate notification are unnecessary unless neurovascular changes occur.
