Instead, I ask, “How many partners have you had in the past 6 months?” This usually reveals when patients have engaged in serial monogamy and creates an environment in which they feel they can disclose one-night stands and sexual activity outside their marriage. The stage is then set for delivering appropriate safe sex messages and screening for sexually transmitted infections.
Easier Eye Irrigation in Children

An effective way for a parent to do this is to put the child in the bathtub, turn on the water, and let the water run onto his or her own arm, starting at the elbow and running down to the hand.
