A nurse is reinforcing teaching about immunizations with a woman in her first trimester of pregnancy whose diagnostic testing indicates she does not have immunity to rubella. The nurse should recommend that the client receive a measles, mumps, rubella (MMR) vaccine at which of the following times?

Choice A rationale: The rooting reflex is a natural reflex in newborns that helps them find the nipple for feeding. When the baby's cheek is touched or stroked, they will turn their head in that direction and open their mouth, searching for the breast or bottle.
Choice B rationale: The Babinski reflex is a different reflex, which involves the fanning and curling of the toes when the sole of the foot is stroked. It is not related to sucking or feeding.
Choice C rationale: The Moro reflex, also known as the startle reflex, occurs when a newborn is startled by a sudden noise or movement. The baby reacts by extending their arms and legs and then bringing them back toward the center of their body. It is not related to sucking or feeding.
Choice D rationale: The stepping reflex is observed when a newborn is held upright with their feet touching a solid surface. The baby will make stepping movements, but it is not related to sucking or feeding.

Choice A rationale: The correct term to document this finding is "Quickening." Quickening refers to the first perception of fetal movement by the pregnant woman, usually described as light fluttering or sensation of movement in the abdomen. It is an exciting milestone for pregnant women and often occurs around 18 to 20 weeks of gestation. It is a significant moment as it indicates the woman can feel the baby's movements, signifying the fetus's increasing activity and growth.
Choice B rationale: Ballottement is a physical examination technique used to assess the fetus's position and movement within the amniotic fluid during pregnancy. It involves a gentle tap on the mother's abdomen to feel the fetus bounce or float in the amniotic fluid.
Choice C rationale: Chloasma, also known as the "mask of pregnancy," refers to dark patches of skin that may appear on the face during pregnancy due to hormonal changes. It is not related to the sensation of fetal movement.
Choice D rationale: Lightening, also known as "engagement," is the process in late pregnancy when the baby's head descends into the pelvis, preparing for childbirth. It often occurs a few weeks before labor begins and can result in the mother feeling less pressure on her diaphragm, which may make breathing easier. It is not related to the perception of fetal movement described by the client.
