A nurse is reinforcing teaching with a parent of a 1-month-old infant who has bilateral clubfoot and is being treated with serial casting. Which of the following statements by the parent indicates an understanding of the teaching?

A. "I will monitor the circulation in my baby's toes.": Checking for adequate circulation is essential when an infant is in casts. Parents should look for signs like pale or cold toes, delayed capillary refill, or swelling, which could indicate compromised blood flow. B. "My baby will need a calcium supplement with feedings.": Calcium supplementation is not part of standard treatment for clubfoot. Nutritional needs are usually met through breast milk or formula in a healthy infant. C. "I will give my baby ibuprofen for excessive crying.": Ibuprofen is not recommended for infants under 6 months of age due to potential kidney and gastrointestinal side effects. Acetaminophen is preferred if pain relief is needed. D. "My baby will need to wear the casts for 4 to 6 months.": Serial casting typically involves changing casts weekly for 6 to 10 weeks. After correction, bracing is used to maintain alignment, not prolonged casting for several months.
