Typically, first-generation OTC antihistamines have a sedating effect because of passage into the CNS. However, in some individuals, especially infants and children, paradoxical CNS stimulation occurs and is manifested by excitement, euphoria, restlessness, and confusion.

Most women who relinquish their infants at birth have come to that decision with a great deal of love and pain. They have made plans in advance. The nurse needs to first provide them with opportunities to express their feelings that might include grief, loneliness, and guilt. A referral for grief counseling might be appropriate if no other support system exists or the mother indicates that she wants assistance working through her grief. If the nurse assesses that the grief process is abnormal, a referral is also appropriate.
The mother has probably already made a decision about whether or not she wants to see her baby. The nurse should ask her and make arrangements for that to happen if the mother requests it. Seeing the baby might aid in the grief process. Until relinquishment occurs, this is the mother's baby and she should be allowed to see it as often as she wants. The mother does have the right to change her mind until final legal arrangements are made. But suggesting this option might lead her to think that the nurse believes she shouldn't relinquish her baby. Health Promotion and Maintenance

The nature of the anemia must be confirmed to ensure that the proper drug regimen is being used. Physiological Adaptation
