A nurse is planning care for a 5-month-old infant who is scheduled for a lumbar puncture to rule out meningitis. Which of the following actions is the MOST important for the nurse to include in the plan of care?

A. Infants do not need to be NPO for 6 hours prior to a lumbar puncture. This is more applicable for procedures requiring sedation or anesthesia. B. A Foley catheter is not necessary for a lumbar puncture. C. Holding the infant in the correct position (chin to chest and knees to abdomen) is crucial for obtaining an accurate sample of cerebrospinal fluid and ensuring the procedure is performed safely. D. Placing the infant in an infant seat post-procedure is not necessary. The infant can be held and comforted by a caregiver.
