Explanation:
(A) Immediately following membrane rupture, the fetus is at risk for complications, not necessarily the mother. (B) The physician is notified after the nurse completes an assessment of the mother's and fetus's conditions. (C) Rupture of membranes facilitates fetal descent. A potential complication is cord prolapse, which is assessed by auscultating fetal heart rate. (D) Rupture of membranes does not necessarily indicate readiness to deliver.

Explanation:
(A) Women who smoke during pregnancy are at increased risk for miscarriage, preterm labor, and IUGR in the fetus. (B) Although smoking produces harmful effects on the maternal vascular system and the developing fetus, it has not been directly linked to fetal anomalies. (C) Smoking during pregnancy has not been directly linked to anemia in the fetus. (D) Smoking during pregnancy has not been linked to nicotine withdrawal symptoms in the newborn.

Explanation:
(A) The ischial spines are located on both sides of the midpelvis. These spines mark the diameter of the narrowest part of the pelvis that the fetus will encounter. They are not sharp protrusions that will harm the fetus. Station refers to the relationship between the ischial spines in the pelvis and the fetus. The ischial spines are designated at 0 station. If the presenting part of the fetus is located above the ischial spines, a negative number is assigned, noting the number of centimeters above the ischial spines. Therefore, 1 centimeter below the ischial spines is designated as +1 station. (B) See explanation in A One centimeter above the ischial spines is designated as +1 station. (C) The pelvic inlet is the first part of the pelvis that the fetus enters in routine delivery. The midpelvis is the second part of the pelvis to be entered by the fetus. The ischial spines are located on both sides of the midpelvis. (D) The pelvic outlet is the last part of the pelvis that the fetus will enter. When the fetus reaches this part of the pelvis, birth is near.

(A)Oxytocin may not be necessary if the bladder is emptied and if the uterus remains firm, midline, and at about U11 after massage. (B) The same rationale as for answer "A" applies.
(C)A full bladder is the most common cause of uterine atony. If the bladder is full, it should be emptied and the uterus reassessed before further intervention. (D) If the bladder is full, the uteruswill not stay contracted or return to a normal position. Overly vigorous massage also encourages uterine atony.

Explanation:
(A) This response validates the client's experience and presents reality to him. (B) This nontherapeutic response minimizes and dismisses the client's verbalized experience. (C) This response can be interpreted by a paranoid client as a threat, thereby increasing the client's potential for violence and loss of control. (D) This response is also threatening. The client's behavior does not call for restraints because he has not lost control or hurt anyone. If seclusion or restraints were indicated, the nurse should never confront the client alone.
