Make sure you choose a faucet that is compatible with your bathroom sink. First, consider whether the faucet will be mounted on the sink, on the counter or on the wall. For sink-mounted faucets, count the number of holes in the deck of the sink (none, one or three) to determine which type of faucet will fit your sink.irst, consider whether the faucet will be mounted on the sink, on the counter or on the wall.

For an adult or an adolescent, carefully insert the tip 7.5 cm to 10 cm (3 to 4 inches); for a child, 5 cm to 7.5 cm (2 to 3 inches); and for an infant, 2.5 cm to 3.75 cm (1 to 1.5 inches). Inserting the tube too far into the rectum can cause perforation.
Rectal temperatures provide the best readings for infants, reports the Mayo Clinic. Place your infant on her back and lift her legs. For infants up to 3 months, lubricate the tip of a rectal digital thermometer and insert it 1/2 to 1 inch into her rectum. It should slide in easily, but if you feel any resistance, stop.
