Need help interpreting a pattern

The pattern reads row 2 and every alternating row:
‘P the p sts, yo’s and yrn’s and k the k sts as they appear to last 5 sts’.
Now does this mean purl the purl stitches AND purl the yo’s and yrn’s? Or does it mean to purl the purls, yarn over the yarn overs and yarn around the yarn arounds and knit the knit sts?

Purl the purls, purl the yo’s and purl the yrn’s and knit the knits. Remember, too that the yo’s and yrn’s occur between stitches and don’t use a stitch.
