The health care provider for a laboring patient makes the following entry into the patient’s record: 3/50%/+1. What instruction will the nurse implement with the patient?

Correct Answer: A

Rationale: The notation "3/50%/+" in the patient's record indicates that the patient is dilated 3 cm, the effacement is 50%, and the presenting part of the fetus is at +1 station. This information signifies that the patient is in active labor. The nurse should implement the instruction of having the patient remain in bed attached to the electronic fetal monitor to closely monitor the progression of labor and the well-being of the fetus. This will allow for continuous assessment and prompt interventions as needed.

Correct Answer: C

Rationale: In the third stage of labor, the separation of the placenta from the uterine wall is a crucial event. The correct answer, option C, states that the fundus descends below the umbilicus, which is indicative of placental separation. This descent occurs as the placenta detaches and is expelled from the uterus. Option A, a gush of blood appears, is incorrect because this is more likely to occur during the first stage of labor when the cervix dilates. Option B, the uterus rises upward in the abdomen, is incorrect as it is not a typical finding in the third stage of labor but may occur during contractions in the first and second stages. Option D, the cord descends further from the vagina, is incorrect as the descent of the cord does not directly indicate placental separation. Understanding these clinical findings is crucial for nurses to accurately assess the progress of labor and ensure proper management during the third stage. Educationally, this question helps reinforce the importance of recognizing key clinical signs of placental separation in the third stage of labor. Nurses must be knowledgeable about these signs to provide safe and effective care to both the mother and the newborn.

Correct Answer: B

Rationale: In the context of labor and delivery, the correct answer is B) Increase in estrogen. Estrogen plays a crucial role in initiating labor by stimulating uterine contractions. As pregnancy progresses, estrogen levels rise, leading to an increase in uterine sensitivity to oxytocin and the development of oxytocin receptors. This hormone also contributes to cervical ripening and the softening of the cervix in preparation for childbirth. Option A) Increase in progesterone is incorrect because progesterone levels actually decrease as labor approaches. Progesterone maintains the uterine quiescence during pregnancy, and its decline allows for the onset of labor. Option C) Increase in human chorionic gonadotropin (hCG) is not directly involved in initiating labor. hCG is primarily responsible for supporting the corpus luteum in early pregnancy and stimulating the production of progesterone. Option D) Aging of placenta is not a factor in the onset of labor. While placental aging can impact fetal well-being, it does not directly trigger the initiation of labor. Understanding the hormonal changes that occur during pregnancy and their impact on the onset of labor is crucial for healthcare providers involved in maternity care. By recognizing the role of estrogen in labor initiation, practitioners can better support and manage the labor process for expectant mothers.

Correct Answer: A

Rationale: In the context of pharmacology, understanding the anatomical considerations for vaginal delivery is crucial for healthcare professionals. The gynecoid pelvis is the most suitable for vaginal delivery due to its round shape, wide diameter, and adequate space for the passage of the baby's head. This type of pelvis is commonly found in the majority of women and is associated with successful and uncomplicated deliveries. The android pelvis (Option B) is more heart-shaped and narrower, making it less suitable for vaginal delivery as it may lead to obstructed labor. The platypelloid pelvis (Option C) is flat and wide, which can also present challenges during delivery. The anthropoid pelvis (Option D) is elongated with a narrow pubic arch, which may require more effort during labor. Educationally, this question highlights the importance of understanding pelvic anatomy in relation to childbirth outcomes. Healthcare providers need to recognize the variations in pelvic shapes and their impact on the labor process to provide optimal care for mothers and babies. By knowing the characteristics of each type of pelvis, healthcare professionals can anticipate potential challenges and intervene appropriately to ensure safe and successful vaginal deliveries.

Correct Answer: D

Rationale: The correct answer is D) Dilation, effacement, and station. In labor and delivery, these three components are crucial assessments to monitor the progress of labor and the descent of the fetus through the birth canal. Dilation refers to the opening of the cervix measured in centimeters, effacement is the thinning of the cervix expressed in percentage, and station indicates the position of the presenting part of the fetus in relation to the ischial spines of the pelvis. Option A) Effacement, station, and dilation is incorrect as the order of the components is reversed. Option B) Dilation, station, and fetal lie is incorrect because fetal lie is not typically included in the assessment of vaginal examinations in labor. Option C) Dilation, effacement, and status of membranes is incorrect as it does not include the station, which is an essential aspect of assessing the descent of the fetus. Understanding these components is crucial for nurses and healthcare providers in labor and delivery settings to accurately assess the progress of labor, determine the need for interventions, and provide appropriate care to the mother and baby.
