Discharge Teaching for an Infant with Single-Ventricle Physiology
A 3-month-old infant with hypoplastic left heart syndrome is 48 hours from discharge after stage I palliation. Feedings are given by nasogastric tube every 3 hours, with a goal of 120 mL/kg/day. The infant weighs 4.2 kg and has oxygen saturations of 78% to 85% at rest. The mother speaks Spanish and has limited literacy in English and Spanish; the father works nights and is rarely home. The family has no reliable car, and the first cardiology follow-up is 3 weeks away. The pharmacy cannot supply the prescribed fortified formula until next week. The discharge nurse has a 30-minute interpreter video session available and must complete teaching before discharge.
1. What barriers to safe discharge do you identify, and what advocacy actions should the nurse take?
Read the worked answer
Barriers include limited English and Spanish literacy, an unreliable caregiver schedule, no transportation, delayed fortified formula, and a 3-week gap before cardiology follow-up. The nurse should not rely on the father or the infant’s older sibling as interpreter. Arrange a professional interpreter for all teaching, use pictures and a large-print step-by-step plan, and confirm who will give feeds at each time. Involve social work/case management for transportation, home health, and formula assistance; call the pharmacy and cardiology to resolve the formula and follow-up gap; ask about WIC and emergency contacts. Advocacy means changing the system around the family, not just telling the mother to comply.
2. Design a teach-back plan for the essential discharge skills and red flags.

Teach in short chunks with the interpreter present: (1) NG tube placement check and feeding volume/fortification; (2) daily weight and how to record it; (3) oxygen saturation goals and when to call; (4) red flags - poor feeding, weight loss, increased work of breathing, saturation below the prescribed range, vomiting, fever, or lethargy; (5) medication doses and emergency plan. After each chunk, use teach-back: “Show me how you would check the tube and give the feeding.” Use return demonstration on a doll and the actual pump. Provide a one-page visual action plan with phone numbers and 911 instructions. Document each skill, who was taught, interpreter used, and the mother’s return demonstration. Avoid yes/no questions such as “Do you understand?”
3. The mother correctly demonstrates feeding but cannot state the saturation threshold for calling cardiology. What should the nurse do?

Do not sign off discharge teaching yet. Re-teach only that gap using the visual plan: state the threshold, show where it is written, and ask her to teach it back in her own words with the interpreter. Connect it to a concrete action: “If the number is below 75%, call this number now; if the baby is breathing hard or blue, call 911.” Have her identify the number on the monitor and on the paper. If she still cannot state it, arrange a home health nurse visit within 24 hours, notify cardiology, and document the unresolved learning need. Discharge can proceed only with a safe plan and follow-up, not with a signed form that overstates understanding.
