A nurse is preparing to administer liquid mycostatin 600,000 units PO TID. Available is mycostatin 100,000 units/mL. How many m. should the

nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason:
Cervical dilation is a definitive sign that labor has begun. During labor, the cervix dilates to allow the baby to pass through the birth canal. The process of cervical dilation begins gradually and progresses until it reaches 10 cm, which is considered full dilation. In a primigravida, or a woman who is pregnant for the first time, this process can take longer compared to women who have given birth before.

Choice B reason:
The presence of amniotic fluid in the vaginal vault could indicate that the client's water has broken, which can be a sign of labor. However, it is not a definitive sign of labor on its own, as the membranes can rupture before labor begins (prelabor rupture of membranes). It is also possible for a woman to have a leak of amniotic fluid without being in active labor.

Choice C reason:
Pain above the umbilicus is not typically associated with labor. Labor pains, or contractions, are usually felt as a tightening or cramping sensation that starts in the back and moves to the front of the abdomen. The pain is more commonly located in the lower abdomen and pelvic area.

Choice D reason:
A brownish vaginal discharge, often referred to as "bloody show," can be a sign that labor is approaching, but it does not confirm that labor has begun. The bloody show is caused by the expulsion of the mucus plug that blocks the cervical canal during pregnancy. While it indicates that the cervix is starting to change, it can occur days before labor starts.

Choice A Reason:
The recommended intake of iron does not necessarily increase during lactation. In fact, the iron requirement may decrease because menstruation usually ceases, reducing iron loss. However, maintaining adequate iron intake is still important for overall health and to support the baby's growth.

Choice B Reason:
Zinc is crucial for immune function, cell division, and growth, making it an important nutrient during lactation. The recommended dietary allowance (RDA) for zinc for lactating women is indeed higher than for non-pregnant, non-lactating women, with an RDA of about 12 mg per day.

Choice C Reason:
While calcium is important for bone health, the recommended intake for lactating women is not as high as 2,000 mg per day. The RDA for calcium for lactating women is about 1,000 mg per day, similar to that for non-lactating women.

Choice D Reason:
The recommended intake of folic acid does not remain the same as for pregnant women. During pregnancy, the RDA for folic acid is higher to prevent neural tube defects. While folic acid is still important during lactation for cell growth and DNA synthesis, the requirement is slightly lower than during pregnancy.
