Question 1 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.
Question 2 of 5
The parents of a young child with heart failure (HF) tell the nurse that they are nervous about giving digoxin. The nurses response should be based on which knowledge?
Correct Answer: D
Rationale: Digoxin?s narrow therapeutic range requires parents to learn specific guidelines for safe administration and monitoring to prevent toxicity. It?s not inherently safe, parents can be taught, and over- or undermedication is a risk without proper guidance.
Question 3 of 5
What nutritional component should be altered in the infant with heart failure (HF)?
Correct Answer: D
Rationale: Infants with heart failure need increased calories due to elevated metabolic rates from poor cardiac function. Fats and protein should be increased to meet caloric needs, and fluids are carefully monitored to avoid overload.
Question 4 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 5 of 5
The nurse is caring for a child with persistent hypoxia secondary to a cardiac defect. The nurse recognizes the risk of cerebrovascular accidents (strokes) occurring. What strategy is an important objective to decrease this risk?
Correct Answer: B
Rationale: Preventing dehydration reduces stroke risk in hypoxic children with polycythemia, as dehydration increases blood viscosity. Seizure control, cardiac output, and energy expenditure are important but don?t directly address stroke risk.
