A newborn infant obtains maternal antibodies from the mother's
- A. laguno.
- B. colostrum.
- C. rubell
- D. placent
Correct Answer: B
Rationale: The correct answer is B: colostrum. Colostrum is the first milk produced by the mother after giving birth. It is rich in antibodies, providing passive immunity to the newborn. This helps protect the infant from infections until its own immune system fully develops.
A: laguno - Not a substance related to maternal antibodies.
C: rubell - Incorrect spelling and not relevant to maternal antibodies.
D: placent - While the placenta does provide nutrients and oxygen to the fetus, it is not the source of maternal antibodies transferred to the newborn.

From fertilization to week 8 of proliferative phase of the uterine pregnancy, the conceptus is called (menstrual) cycle? ________.
- A. estrogens
- B. a fetus
- C. progesterones
- D. an embryo
Correct Answer: D
Rationale: The correct answer is D: an embryo. From fertilization to week 8 of the proliferative phase of uterine pregnancy, the conceptus is referred to as an embryo. This is because during this period, the fertilized egg undergoes rapid cell division and differentiation, leading to the formation of distinct embryonic structures and the beginning of organ development. The term "fetus" is used after the embryonic stage, typically from week 9 onwards. Choices A and C, estrogens and progesterones respectively, are hormones involved in regulating the menstrual cycle and maintaining pregnancy but are not terms used to describe the developing conceptus itself during this specific timeframe.
Female infertility can be caused by hormonal problems, blocked fallopian tubes, and
- A. a cold
- B. lack of appetite
- C. irregular menstrual cycles
- D. STDs
Correct Answer: D
Rationale: The correct answer is D: STDs. Sexually transmitted diseases (STDs) can lead to pelvic inflammatory disease (PID) which can cause scarring and blockage of the fallopian tubes, leading to female infertility. STDs such as chlamydia and gonorrhea can also cause damage to the reproductive organs, affecting fertility. Therefore, STDs are a significant factor contributing to female infertility.
A: A cold is a common viral infection that does not directly impact female fertility.
B: Lack of appetite is not a known cause of female infertility.
C: Irregular menstrual cycles can be a symptom of hormonal imbalances but may not directly lead to infertility.
The nurse will plan to teach a 51-yr-old man who is scheduled for an annual physical examination about a(n)
- A. increased risk for testicular cancer.
- B. possible changes in erectile function.
- C. normal decreases in testosterone level.
- D. prostate specific antigen (PSA) testing.
Correct Answer: C
Rationale: The correct answer is C: normal decreases in testosterone level. At the age of 51, it is important to educate the man about the normal age-related decline in testosterone levels, which can affect various aspects of health. This information will help manage expectations and address potential symptoms. Option A is incorrect as testicular cancer risk typically decreases with age. Option B may be a concern but is not the primary focus of education for a routine physical exam. Option D (PSA testing) is more relevant for prostate health, which is not the main focus of education for a 51-year-old man's annual physical exam.
Vener/o refers to:
- A. Vagina
- B. Vulva
- C. Sexual intercourse
- D. Hymen
Correct Answer: B
Rationale: The correct answer is B: Vulva. The term "vener/o" specifically refers to the external female genitalia, which includes the labia, clitoris, vaginal opening, and other structures collectively known as the vulva. The term does not refer to the vagina (A), which is the internal canal leading to the cervix. It also does not refer to sexual intercourse (C), which is the act of engaging in sexual activity. Lastly, it is not related to the hymen (D), which is a thin membrane partially covering the vaginal opening. Therefore, based on the definition and context of the term "vener/o," the correct answer is B: Vulva.
Which of the following statements is incorrect.
- A. a female has approximately 2-4 million oocytes at birth
- B. a female has approximately 6 million oogonia during fetal development
- C. a female ovulates about 2,000 to 4,000 oocytes during her life
- D. only approximately 1-5 oocytes are fertilized
Correct Answer: C
Rationale: The correct answer is C because a female actually ovulates only about 400-500 oocytes during her lifetime, not 2,000 to 4,000. This is due to the process of follicular atresia where many oocytes are lost before ovulation. Choice A is correct as females have a finite number of oocytes at birth. Choice B is correct as oogonia differentiate into primary oocytes during fetal development. Choice D is incorrect as typically only one oocyte is fertilized during each menstrual cycle.
