17
Q
- The third stage of labour involves
A

19
Q
- Implantation of zygote into endometrium usually takes place on which day after fertilization
A
5-6th
20
Q
- To test for the presence of genetic disorders such as Down’s syndrome or haemophiliacs in the foetus, which
would be the investigation of choice?
A
Amniocentesis
21
Q
- For the first 2 months after fertilisation of zygote the developing new life is called an
A
embryo
22
Q
what surrounds the developing foetus and serves as a shock absorber.
A
- The amniotic fluid
23
Q
- The term “show” in labour refers to
A
discharge of cervical mucus plug
24
Q
- Copper T is a device that prevents the attachment of a fertilised ovum to the endometrium. It is known as a/an
A
IUD device.
25
24. When the foetus is born feet first, it is known as a
breech presentation.
26
25. A thick jelly like substance in the umbilical cord prevents it from kinking. It is known as
Whartons Jelly_.
27
26. The total absence of menstruation is known as
ammenorrhoea.
28
1. The presence of the hormone which in the urine is an indication of pregnancy.
HCHG
29
28. The dartos and cremaster muscles are important to the integrity of the male reproductive system. What role they play?
Pull the testes towards the abdomen when in cool climates
30
29. The ability of sperm cells to move along the ductus deferens is due to
peristalsis.
31
30. The ability of a male to ejaculate is due to the action of
ischiocavernosus muscle.
32
The most important risk for testicular cancer in young males is
cryptorchid/undecemded testis.
33
32. Development of male primary reproductive structures depends on secretion of
foetal testerone prenatally and lasting into the first few months after birth.
34
33. The primary function of the endometrium is to receive
retain, and nourish a fertilized ovum
35
34. If gametes were diploid like somatic cells, how many chromosomes would the zygote contain?
92.
36
35. The constancy of the chromosome number from one cell generation to the next is maintained through
meiosis.
37
36. The development of testes as opposed to ovaries is considered as primary or secondary sexual characteristic?
Primary.
38
37. Characteristics of the mature sperm include the presence of which chromosomes in approximately half the sperm.
Y
39
38. Secretion of progesterone stimulates
secretive activity of the uterine myometrium
40
39. The testicular cells that construct the blood-testis barrier are the
Sustentacular/Sertoli
41
40. Testosterone does what
stimulates the male pattern of development, contributes to male sexual behavior and spermatogenesis, and stimulates muscle and bone synthesis.
42
41. If fertilization occurs, the corpus luteum is maintained by a hormone secreted by the developing embryo called
Human chorionic gonadotrophic hormone.
43
42. The mammary glands are modified
sweat glands
that are actually part of the integumentary system.
44
43. Normally menstruation occurs when blood levels of
progesterone decrease dramatically.
45
44. Semen does not enter the urinary bladder during ejaculation because the smooth muscle sphincter at the base of the
urinary bladder closes.
46
45. A boy who has not passed through puberty sustains an injury to his anterior pituitary such that FSH is no longer released, but LH is normal. After he grows to maturity, one would expect that he would be
infertile.
47
46. A low secretion of luteinizing hormone (LH) in the normal male adult would cause decreased
testosterone secretion.
48
47. The portion of the uterine endometrium that is not sloughed off every month is called the
stratum basalis.
49
48. Because of the resurgence of cervical cancer in young women, what important information should a nurse share with young women at a local health fair?
The human papilloma virus (HPV) vaccine prevents infection with certain species of HPV associated with the development of cervical cancer, genital warts ex Gardasil
50
49. Based on your knowledge of how the prostate encircles part of the urethra, what will be the main clinical manifestations of an enlarged prostate?
Incontinence and urinary obstruction________
51
50. Two alleles expressing exactly the same information for a trait are designated as
homozygous
52
51. Dominant alleles are so called because under most circumstances they
suppress the expression of other alleles.
53
52. Recessive genes are usually expressed in humans only when both alleles are exactly the same, or
or the organism is in the embryonic stage.
54
53. Observable characteristics expressed by the genes for a trait are called the
Phenotypic
55
54. An example of multiple-allele inheritance is
ABO blood group
56
55. Sex chromosomes of a normal male are
XY.
57
56. An individual who is heterozygous for a particular trait, yet expresses both alleles of that trait, is an example of
incomplete dominance
58
57. The X and Y chromosomes are considered the
Sex chromosomes.
59
58. Removing a sample of the fluid surrounding the fetus for the purpose of studying the chromosomes is a procedure called
Amniocentesis
60
59. The ABO blood type is a good example of a(n)
Multiple-allele inheritance.
