Human Reproductive System Quizlet Questions
Question 1 of 5
Choose the correct sequence of human embryonic development.
Correct Answer: D
Rationale: The correct sequence of human embryonic development is D: Fertilization - cleavage - gastrulation - organogenesis. 1. Fertilization: The union of egg and sperm forms a zygote. 2. Cleavage: Zygote undergoes rapid cell division without growth. 3. Gastrulation: Formation of three germ layers (ectoderm, mesoderm, endoderm). 4. Organogenesis: Organ formation from germ layers. This sequence reflects the chronological order of events in early human development. Choice A is incorrect as organogenesis occurs after gastrulation. Choice B is incorrect as fertilization should precede cleavage. Choice C is incorrect as organogenesis occurs after gastrulation.
Question 2 of 5
Select the following structures which participate in forming the pelvic brim
Correct Answer: A
Rationale: The correct answer is A: Arcuate line. The pelvic brim is formed by structures at the pelvic inlet. The arcuate line is a ridge on the inner surface of the ilium that contributes to the boundary of the pelvic brim. The other choices, B: Marginal ala of sacrum, C: Pubic tubercle, and D: Sacral promontory, do not directly participate in forming the pelvic brim. The marginal ala of the sacrum is part of the sacrum, the pubic tubercle is located on the pubis bone, and the sacral promontory is a landmark on the sacrum but does not contribute to the pelvic brim.
Question 3 of 5
Regarding the function of placenta
Correct Answer: B
Rationale: Step 1: The placental barrier is semi-permeable, allowing small molecules like oxygen and nutrients to pass but blocking larger molecules like antibodies. Step 2: IgG antibodies are the only type that can cross the placenta through active transport mechanisms. Step 3: This transfer provides passive immunity to the fetus. Step 4: Options A, C, and D are incorrect as the placenta has 4 main layers, progesterone does not induce preterm labor, and gas diffusion depends on concentration gradients, not pressure gradients.
Question 4 of 5
The nurse is reviewing discharge plans with a client who is recovering from a cervical biopsy. Which statements indicate good understanding by the client? (Select all that apply.)
Correct Answer: B
Rationale: Correct Answer: B Rationale: The client understanding that they cannot carry their toddler for 2 weeks after a cervical biopsy is crucial to avoid strain and potential complications. Lifting heavy objects can place stress on the biopsy site, leading to bleeding or infection. This restriction promotes proper healing and reduces the risk of complications. Summary: A: Returning to work immediately may not allow sufficient time for recovery and could lead to complications. C: Douching can introduce bacteria to the biopsy site, increasing the risk of infection. D: Waiting for about 2 weeks before having intercourse is important to prevent trauma to the biopsy site.
Question 5 of 5
The substrate used for sperm metabolism is produced by the _____.
Correct Answer: B
Rationale: The correct answer is B: seminal vesicle. Seminal vesicles produce fructose-rich fluid that serves as a nutrient source for sperm metabolism. This energy supply enables sperm to swim and undergo various metabolic processes. The other choices are incorrect because the prostate produces components of semen, Cowper's gland secretes pre-ejaculatory fluid, and the testes produce sperm cells but not the substrate for sperm metabolism. Thus, the seminal vesicle is the most direct source of the metabolic substrate for sperm.
