A woman who is 6 weeks' pregnant is in for her prenatal appointment and asks the nurse when the sex of the baby can been determined by ultrasound. The
... [Show More] nurse bases her answer on the knowledge that
The sex cannot be determined by ultrasound; an amniocentesis must be done
The sex of the baby can be determined now by ultrasound
The external genitalia look similar in both males and females until about 9 weeks of gestation
The external genitalia will look different at 6 weeks, so an ultrasound can be done at that time - The external genitalia look similar in both males and females until about 9 weeks of gestat
A. Sex of a fetus can be determined by ultrasound after the 9th week.
B. Sex of a fetus cannot be determined until about 9 weeks of gestation.
C. The external genitalia starts to change at about 9 weeks of gestation. Prior to that time, males and females look similar and it is not possible to determine the sex from ultrasound.
D. Sex of a fetus cannot be determined until about 9 weeks of gestation.
When teaching a group of mothers of preteen girls, the nurse explains that the earliest outward sign of puberty starting is ____________. - breast change
A 16-year-old is being seen for the first time by the nurse practitioner. The young woman states that she has not had the onset of menstruation yet. Her breasts are developing and her pelvis has widened. The term used to describe this list of signs and symptoms is ___________. - "primary amenorrhea"
The nurse is reviewing the lab reports on a 17-year-old new patient. The gonadotropin-releasing hormone levels are extremely low. The nurse can anticipate that the patient will
Look older than her years
Not have primary or secondary sexual characteristics
Have primary, but not secondary, sexual characteristics
Have adequate levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) - Not have primary or secondary sexual characteristics
A. With low levels of GNRH, she will look younger, because she has not started to develop sexual characteristics.
B. Gonadotropin-releasing hormone is responsible for initiating the beginning of puberty.
C. With low levels of GNRH, she will not have primary or secondary sexual characteristics.
D. The level of GNRH increases slowly until it is adequate to stimulate the anterior pituitary to increase its production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
A 23-year-old postpartum woman is having trouble breastfeeding. Upon assessment, the nurse discovers that the woman does not have a let-down reflex. One reason for this may be that she is lacking the hormone ________________. - oxytocin
When comparing the endometrial cycle with the ovarian cycle on day 22,
The progesterone level is at its peak, but the LH level is low
The progesterone level is low, but the FSH level is at its peak
The estrogen level is low, but the LH level is at its peak
Both the estrogen level and the LH level are at the peak - The progesterone level is at its peak, but the LH level is low
A. In the endometrial cycle on day 22, the progesterone level has reached its peak and will start decreasing in 1 to 2 days. In the ovarian cycle at the same time, the LH levels have already dropped and will remain low until about day 10 on the next cycle.
B. On day 22, the progesterone level should about be at its peak and the LH level should be low.
C. On day 22, the estrogen level is high and the LH level is low.
D. On day 22, the estrogen level is high and the LH level is low.
During a childbirth class a woman asks the nurse, "I'm just 8 weeks pregnant. I know the placenta is not fully developed yet, so what is producing all the hormones I need?" The nurse will development her answer on the knowledge that
The placenta is big enough at this point to produce the hormones necessary
Extra hormones are not necessary for this stage of the pregnancy
The pituitary is working to secrete the extra hormones that are necessary until the placenta develops
The corpus luteum secretes the extra hormones necessary until the placenta develops - The corpus luteum secretes the extra hormones necessary until the placenta develops
A. The placenta is not mature enough to produce the estrogen and progesterone necessary to support the pregnancy. The corpus luteum will do this until the placenta is mature.
B. Extra estrogen and progesterone are necessary to support the pregnancy.
C. The pituitary will secrete the LH necessary to keep the corpus luteum until conception occurs. After conception, the fertilized ovum will secrete human chorionic gonadotropin to keep the corpus luteum going. The corpus luteum secretes the extra hormones necessary for the pregnancy.
D. LH causes the follicle to persist as a corpus luteum for about 12 days after ovulation. If conception occurs, the fertilized ovum secretes human chorionic gonadotropin that causes the corpus luteum to persist. The corpus luteum produces the extra estrogen and progesterone necessary to support the pregnancy.
Which is a secondary sexual characteristic?
Female breast development
Production of sperm
Maturation of ova
Secretion of gonadotropin-releasing hormone - Female breast development
A. A secondary sexual characteristic is one not directly related to reproduction, such as development of the characteristic female body form.
B. Sperm production is directly related to reproduction and therefore is not a secondary sexual characteristic.
C. Maturation of ova is directly related to reproduction and therefore is not a secondary sexual characteristic.
D. Secretion of gonadotropin-releasing hormone is directly related to reproduction and therefore is not a secondary sexual characteristic.
The average man is taller than the average woman at maturity because of
A longer period of skeletal growth.
Earlier development of secondary sexual characteristics.
Earlier onset of the growth spurt.
Starting puberty at an earlier age. - A longer period of skeletal growth.
A. The man's greater height at maturity is the combined result of beginning the growth spurt at a later age and continuing it for a longer period of time.
B. Males start puberty 6 months to 1 year later than females.
C. Males start puberty 6 months to 1 year later than females.
D. Males start puberty 6 months to 1 year later than females.
Fertilization of the ovum takes place in which part of the fallopian tube?
Interstitial portion
Ampulla
Isthmus
Infundibulum - Ampulla
A. The interstitial portion runs into the uterine cavity and lie within the uterine wall. If fertilization occurs in this section, it is too close to the site of implantation, and the fertilized ovum would not have time to properly develop prior to implantation.
B. The ampulla is the wider middle part of the tube lateral to the isthmus and is where fertilization occurs.
C. The isthmus is the narrow part of the tube adjacent to the uterus. If fertilization occurs in this section, it is too close to the site of implantation, and the fertilized ovum would not have time to properly develop prior to implantation.
D. The infundibulum is the wide, funnel-shaped terminal end of the tube toward the ovaries. If fertilization occurred in this section, the fertilized ovum could travel out into the abdominal cavity.
During the first 2 weeks after conception, the fertilized ovum is called a ____________. - zygote
To maintain the corpus luteum and the continuing supply of estrogen and progesterone, the zygote secretes which hormone? - Human choronic gonadotropin
A. Prolactin is produced in the pituitary glands, and is necessary for breast milk production.
B. Lutenizing hormone is produced in the pituitary glands and is necessary for the release of the mature ovum at ovulation.
C.The cells of the zygote secrete human chorionic gonadotropin. The hCG feeds back into the ovum to prolong the corpus luteum.
D. Oxytocin is produced in the pituitary glands and is necessary for contractions during labor and the let-down reflex with breast feeding.
Implantation of the zygote should occur in the upper portion of the uterus. This is the best area for the growing fetus and placenta for all of these reasons except
The upper uterus is richly supplied with blood
The upper uterus lining is thick
The upper uterus is supplied with the beginnings of the umbilical cord
The muscle fibers of the upper uterus prevent blood loss postdelivery - The upper uterus is supplied with the beginnings of the umbilical cord
A. The upper uterus is rich with blood. This is optimal for fetal gas exchange and nutrition.
B. The uterine lining is thicker in the upper portion. This prevents the placenta from attaching so deeply that it does not easily detach after birth.
C. The umbilical cord develops from the zygote.
D. The muscle fibers of the upper portion of the uterus are strong interlacing fibers that will clamp down over the site of placental separation, preventing excessive bleeding.
Basic structures of all major body organs are completed during the __________ period of development. - embryoic [Show Less]
