The nurse is developing a teaching plan for a client who is scheduled for her first Papanicolaou test. What instruction by the nurse is the most accurate?
- A. “The timing of the Pap smear does not matter.”
- B. “Sexual intercourse will not interfere with the results.”
- C. “Results can be interpreted immediately in the offic
- D. “Results are best if you do not douche 24 hours before the test.”
Correct Answer: D
Rationale: The correct answer is D. Douching can alter the cervical cells and affect the accuracy of the Pap smear results. The rationale is that douching can wash away or change the cervical cells, leading to potential misinterpretation of the test results. Choices A and B are incorrect because the timing of the test and sexual activity can indeed affect the results. Choice C is incorrect as Pap smear results need to be sent to a lab for interpretation by a healthcare provider, not done immediately in the office.

Bidder's canal receives __________.
- A. Eggs
- B. Sperms
- C. Ammonia
- D. Oxygenated blood
Correct Answer: D
Rationale: The correct answer is D: Oxygenated blood. Bidder's canal is a part of the male reproductive system and functions to transport oxygenated blood to the testicles. This is essential for maintaining the temperature required for sperm production. Eggs (A) are not transported through Bidder's canal as it is specific to male reproductive functions. Sperms (B) are produced in the testicles but are not transported through Bidder's canal. Ammonia (C) is a waste product and not involved in the circulation within the male reproductive system.
Semen leaves the male body when the penis is erect and
- A. urination occurs
- B. evacuation occurs
- C. excitement occurs
- D. ejaculation occurs
Correct Answer: D
Rationale: The correct answer is D: ejaculation occurs. When the penis is erect, semen is released from the male body through ejaculation. During sexual arousal, the muscles contract, pushing semen through the urethra and out of the body. Urination (choice A) is a separate process controlled by the bladder, not related to semen release. Evacuation (choice B) refers to bowel movements, not semen release. Excitement (choice C) is a psychological state and does not directly lead to semen leaving the body. Therefore, the correct answer is D as it accurately describes the physiological process of semen leaving the male body during ejaculation.
Choose the statement that is NOT TRUE:
- A. Fragmentation is followed by regeneration.
- B. The offspring from asexual reproduction is genetically identical.
- C. The embryo of ovoviviparous gets nourishment from the egg yolk.
- D. Crossing-over occurs between sister chromatids of homologous chromosomes.
Correct Answer: D
Rationale: The correct answer is D because crossing-over occurs between non-sister chromatids of homologous chromosomes during meiosis, not between sister chromatids. This genetic exchange results in genetic variation. Fragmentation is followed by regeneration in some organisms, asexual reproduction produces genetically identical offspring, and ovoviviparous embryos do get nourishment from the egg yolk.
Which of the following structures is often referred to as the bag of water?
- A. Urinary bladder
- B. Gall bladder
- C. Amniotic sac
- D. Uterus
Correct Answer: C
Rationale: The correct answer is C: Amniotic sac. This structure is often referred to as the "bag of water" because it is a fluid-filled sac that surrounds and protects the developing fetus during pregnancy. The amniotic sac provides cushioning and maintains a stable environment for the fetus to grow. It is essential for the baby's development and acts as a barrier against infections.
Choice A: Urinary bladder - This structure is responsible for storing urine and is not typically referred to as the bag of water.
Choice B: Gall bladder - This organ stores bile produced by the liver and aids in digestion, not related to pregnancy or fetal development.
Choice D: Uterus - While the uterus is involved in pregnancy and fetal development, it is not commonly referred to as the bag of water.
Where does fertilization usually occur in the female reproductive system?
- A. Ovary
- B. Vesicular (Graafian) follicle
- C. Uterine (fallopian) tubes
- D. Uterus
Correct Answer: C
Rationale: The correct answer is C, the uterine (fallopian) tubes. This is where fertilization usually occurs as it is the site where the egg and sperm meet. The egg is released from the ovary and travels through the fallopian tube where it can be fertilized by sperm. If fertilization occurs, the resulting embryo will then travel to the uterus for implantation. The other choices are incorrect because fertilization does not typically occur in the ovary (A) or vesicular (Graafian) follicle (B). While the uterus (D) is where the embryo implants and develops into a fetus, fertilization itself does not occur there.
