Chapter 23 Questions
Question 1 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.
Question 2 of 5
Decreasing the demands on the heart is a priority in care for the infant with heart failure (HF). In evaluating the infants status, which finding is indicative of achieving this goal?
Correct Answer: C
Rationale: Appropriate weight gain indicates successful feeding and reduced caloric loss, reflecting decreased cardiac demand. Irritability and prolonged capillary refill suggest ongoing HF, and high Fowler positioning aids breathing but doesn?t confirm reduced cardiac strain.
Question 3 of 5
The physician suggests that surgery be performed for patent ductus arteriosus (PDA) to prevent which complication?
Correct Answer: D
Rationale: PDA causes left-to-right shunting from the aorta to the pulmonary artery, leading to pulmonary vascular congestion. Surgery prevents this complication. Hypoxemia is linked to mixed flow defects, the shunt is left-to-right, and PDA increases left heart workload.
Question 4 of 5
The nurse finds that a 6-month-old infant has an apical pulse of 166 beats/min during sleep. What nursing intervention is most appropriate at this time?
Correct Answer: C
Rationale: A sleeping pulse over 160 beats/min suggests tachycardia, an early sign of heart failure due to sympathetic stimulation, requiring practitioner evaluation. Oxygen or positioning may be needed later, but reporting is the priority. Recording alone delays intervention.
Question 5 of 5
What clinical manifestation is a common sign of digoxin toxicity?
Correct Answer: B
Rationale: Vomiting, unrelated to feedings, is a common sign of digoxin toxicity due to its narrow therapeutic range. Seizures are not associated, bradycardia (not bradypnea or tachycardia) may occur, but vomiting is a key indicator.
