The cortical area of the ovary contains:
- A. primordial follicles;
- B. mature follicles;
- C. secondary follicles;
- D. blood vessels;
Correct Answer: A
Rationale: Step 1: The cortical area of the ovary is the outer layer where follicles develop.
Step 2: Primordial follicles are the earliest stage of follicle development, found in the cortex.
Step 3: Mature follicles are developed follicles located deeper in the ovary, not in the cortex.
Step 4: Secondary follicles are also more developed than primordial follicles, located deeper.
Step 5: Blood vessels are important for supplying nutrients but are not specific to the cortical area.
Therefore, the correct answer is A as primordial follicles are located in the cortical area, while other choices are found in different regions of the ovary.

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.
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.
FSH causes several immature EGGS, along with their surrounding FOLLICLE cells, in the ovaries to begin to develop. The developing follicle cells release increasing amounts of ________________.
- A. hormone
- B. estrogen
- C. progesterone
- D. Implantation
Correct Answer: B
Rationale: Step-by-step rationale:
1. FSH stimulates development of follicles in ovaries.
2. Follicle cells release estrogen.
3. Estrogen levels increase as follicles develop.
4. Estrogen plays key role in menstrual cycle regulation.
Therefore, the correct answer is B (estrogen). Other choices are incorrect: A (hormones are broad, not specific), C (progesterone is released after ovulation), D (implantation occurs in the uterus, not ovaries).
Neonates that are kept in 100% oxygen incubators for several days become blind when they are removed from the incubator, a condition referred to as retrolental fibroplasia. What is the explanation for the loss of sight?
- A. The high concentration of oxygen stimulates the growth of fibrous tissue into the retina
- B. The high concentration of oxygen causes rupture of blood vessels in the retina, resulting in fibrous infiltration of the vitreous humor
- C. The high concentration of oxygen retards the growth of blood vessels in the retina, but when the oxygen therapy is stopped, the fall in oxygen concentration stimulates an overgrowth of blood vessels in the retina and vitreous humor, which later become densely fibrous and block the light from the pupil
- D. The high concentration of oxygen destroys the retinal neurons
Correct Answer: C
Rationale: The correct answer is C because high oxygen concentration in neonates suppresses normal blood vessel growth in the retina. When oxygen therapy is stopped, oxygen levels fall, triggering excessive blood vessel growth in the retina and vitreous humor, leading to fibrous blockage of light. Option A suggests fibrous tissue growth due to oxygen, which is incorrect. Option B inaccurately states that oxygen causes vessel rupture. Option D is incorrect as oxygen does not directly destroy retinal neurons.
A client is concerned about her irregular menstrual periods since she has increased her daily workouts at the gym to 2 hours each day. What is the nurses best response?
- A. Do you want to talk about the need for that much exercise?
- B. Exercise is healthy but can decrease body fat and cause irregular periods. Test Bank - Medical-Surgical Nursing: Concepts for Interprofessional Collaborative Care 9e 588
- C. Bingeing and purging can cause electrolyte problems in your body.
- D. Anorexic behavior can result in decreased estrogen levels.
Correct Answer: B
Rationale: The correct answer is B. Increasing exercise intensity can lead to decreased body fat percentage, impacting hormonal balance and causing irregular periods. This is known as athletic amenorrhea. Choice A is incorrect as it does not address the physiological impact of excessive exercise on menstrual cycles. Choices C and D are also incorrect as they refer to eating disorder behaviors, which are not directly related to the client's concern of irregular periods due to increased exercise.
