GUIDE QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS
What issues are associated with Patent Ductus Arteriosus (PDA)? ✔✔ PDA
occurs when the arterial connection between the aorta and pulmonary artery
fails to seal naturally after birth. This causes excess blood to recirculate into
the lungs, reducing systemic blood flow throughout the body and leading to a
wide pulse pressure.
What are the main objectives and approaches for treating PDA? ✔✔ Surgical
correction involves placing a clip on the ductus to block extra blood from
flowing back to the lungs, thereby improving systemic circulation to the body.
Alternatively, medications like indomethacin can be administered to stimulate
closure of the opening without surgery.
What assessment findings would the nurse anticipate finding in an infant with
coarctation of aorta? -ANSWER ✔✔-narrowing of aorta
-Increased BP in upper extremities
-Nosebleeds
-Weak or absent lower extremity pulses
-Cool lower extremities
What are the 4 problems in a child with Tetralogy of Fallot? -ANSWER ✔✔-VSD
= ventricular septal defects - hole in heart
-Overriding aorta (part opens in RV), aorta in wrong spot
-R ventricular hypertrophy - enlargement of cardiac muscle
-Pulmonic stenosis - narrowing of pulmonary artery
-------Murmur
-------Cyanotic
, -------Dyspnea
-------Polycythhemia
What instructions should the nurse provide parents who are having to administer
Digoxin to their child? -ANSWER ✔✔- BP and anti-arrhythmic
-Very narrow therapeutic range
-Do not administer if HR below 90 in infants and below 70 in children
-Nurse watches parent measure the elixir in the dropper and stresses the level mark
as the meniscus of the fluid that is observed at eye level
-Signs of dig toxicity: yellow vision, N/V, diarrhea, leads to dehydration
-Same time every day and twice a day
Purpose of administration of Lasix (Furosemide) to kids w/ CHF -ANSWER ✔✔-
Remove accumulated fluid and sodium
-Strict I/O
What are the benefits of supplementally feeding an infant with CHF tube feedings?
-ANSWER ✔✔-Small frequent feedings to help decrease oxygenation
consumption
-Monitors intake more strictly
-Control calories to help with growth and development
-Can monitor fluid
-Not having to work for calories
what all is involved in the nursing care of the infant/child with CHF? -ANSWER
✔✔-Improve cardiac function/output
Digoxin
