When educating parents about sun safety for their infant, which recommendation is most important?

The correct answer to the question "When educating parents about sun safety for their infant, which recommendation is most important?" is Option B: Dress infants in lightweight long-sleeved clothing and wide-brimmed hats.

The other options — A) Apply sunscreen with SPF 15 to infants younger than 6 months, C) Allow infants to have direct sun exposure for 30 minutes daily for Vitamin D synthesis, D) Use tanning lotions for babies to prevent sunburn — are incorrect for this NCLEX-RN Exam Prep question. As explained above: For infants under 6 months, protection from direct sun exposure through shade, clothing (long sleeves, hats), and avoiding peak sun hours is prioritized over sunscreen application.
