The stage of labor that involves
- A. relaxin the delivery of the infant is the
- B. progesterone ________.
- C. chorion
- D. dilation stage
Correct Answer: D
Rationale: The correct answer is D: dilation stage. This is the stage of labor where the cervix dilates to allow for the passage of the baby through the birth canal. This stage is crucial for the progression of labor and eventual delivery of the infant. Option A, relaxin, is a hormone that helps soften the cervix and pelvic ligaments but is not directly related to the stage of labor mentioned. Option B, progesterone, is a hormone involved in maintaining pregnancy and preparing the uterus for implantation, not specifically related to the dilation stage. Option C, chorion, is a membrane surrounding the fetus and plays a role in nutrient exchange, not directly related to the dilation stage of labor.

Which of the following reasons should a nurse provide a client when asked about the purpose of a Papanicolaou test?
- A. It is used to detect early breast cancer.
- B. It is used to detect early cancer of the Cervix.
- C. It is used to detect the fertility status of the woman.
- D. It is used to detect early stages of an STD.
Correct Answer: B
Rationale: The Pap test is specifically designed to detect early cervical cancer.
Choose the CORRECT statement regarding events that occur in metaphase II.
- A. Sister chromatids may no longer be identical to each other.
- B. Homologous chromosomes line up at metaphase plat
- C. Crossing over between homologous chromosomes occurs.
- D. Homologous chromosomes begin to separat
Correct Answer: A
Rationale: Correct Answer: A - Sister chromatids may no longer be identical to each other.
Rationale:
1. In metaphase II, sister chromatids align at the metaphase plate.
2. During meiosis II, sister chromatids separate and move to opposite poles.
3. Due to potential crossing over in meiosis I, sister chromatids may not be identical in meiosis II.
4. This variability contributes to genetic diversity in the resulting gametes.
Summary:
B: Homologous chromosomes do not line up in metaphase II; they already separated in meiosis I.
C: Crossing over occurs in meiosis I, not in meiosis II.
D: Homologous chromosomes start to separate in anaphase I, not metaphase II.
A surge of FSH and LH is induced in the adenohypophysis 24 hours before ovulation and the first meiotic division of the primary oocyte resumes. At what stage does the oocyte become arrested until it becomes fertilized?
- A. First meiotic division, prophase
- B. First meiotic division, metaphase
- C. Second meiotic division, prophase
- D. Second meiotic division, metaphase
Correct Answer: D
Rationale: The correct answer is D: Second meiotic division, metaphase. After the surge of FSH and LH induces the first meiotic division to resume, the oocyte becomes arrested at the metaphase stage of the second meiotic division until fertilization. This arrest allows for the completion of meiosis upon fertilization. Choices A and B are incorrect because the oocyte does not become arrested at the prophase or metaphase of the first meiotic division. Choice C is incorrect because the oocyte does not become arrested at the prophase of the second meiotic division, but rather at the metaphase stage.
The condition of a hidden testicle is of which type of tissue?
- A. skeletal muscle
- B. phimosis.
- C. epithelial tissue
- D. orchiditis.
Correct Answer: D
Rationale: The correct answer is D: orchiditis. Orchiditis refers to inflammation of the testicle, which is a type of tissue found in the male reproductive system. This condition specifically affects the testicular tissue, leading to pain, swelling, and possible complications. Skeletal muscle (choice A) is not related to the testicle, phimosis (choice B) is a condition of the foreskin, and epithelial tissue (choice C) primarily covers the surface of organs, not the testicle itself. Therefore, orchiditis is the most relevant choice for a condition affecting testicular tissue.
The nurse is reviewing discharge instructions with a client who has just experienced an endometrial biopsy. Which finding would be reported to the primary health care provider immediately?
- A. Mild cramping
- B. Slight chills and fever
- C. Spotting of blood
- D. Fatigue after anesthesia
Correct Answer: B
Rationale: The correct answer is B, slight chills and fever. This finding may indicate an infection, which can be a serious complication post-endometrial biopsy. Fever and chills can be signs of systemic infection, requiring immediate medical attention to prevent further complications. Mild cramping (A) is a common post-procedure symptom. Spotting of blood (C) is also normal after an endometrial biopsy. Fatigue (D) after anesthesia is expected and not an immediate concern unless severe or persistent.
