Question 1 of 5
Choose the CORRECT match. Animals Fertilization Embryonic development
Correct Answer: C
Rationale: The correct match is C: Frog - External Oviparity. Frogs lay eggs externally, and their fertilization and embryonic development occur outside the female's body. This is characteristic of oviparous animals. The other choices are incorrect because: A: Dog - Internal Oviparity, dogs give birth to live young and do not lay eggs. B: Duck - External Viviparity, ducks also give birth to live young and do not lay eggs externally. D: Cat - Internal Ovoviviparity, cats give birth to live young but retain eggs inside their body until they hatch.
Question 2 of 5
A 67-year-old male client had serum laboratory tests performed during his annual examination. The nurse reviews his results, as
Correct Answer: D
Rationale: The correct answer is D. The nurse should communicate that the results were normal because the specific antigen and prolactin levels fall within the normal range for a 67-year-old male. Specific antigen levels around 10 ng/mL are typical for this age group, and prolactin levels of 5 ng/mL are also within normal limits. Option A is not necessary as the results are normal. Option B is incorrect as galactorrhea is not indicated by the lab results. Option C is also incorrect as there is no indication of a testicular tumor based on the lab values. Therefore, the best course of action is to inform the client that the results are normal.
Question 3 of 5
Where does the epididymis direct sperm cells into?
Correct Answer: B
Rationale: The epididymis directs sperm cells into the vas deferens. Sperm mature in the epididymis and are stored there until ejaculation. The vas deferens then carries the mature sperm from the epididymis to the urethra for ejaculation. The other choices are incorrect because the vas efferens carries sperm from the rete testis to the epididymis, the rete testis is a network of tubules where sperm is collected from the seminiferous tubules, and the prostate gland secretes fluids that contribute to semen but does not direct sperm flow.
Question 4 of 5
Testosterone is converted to _____ in the prostate.
Correct Answer: D
Rationale: The correct answer is D: dihydrotestosterone. Testosterone is converted to dihydrotestosterone (DHT) in the prostate by the enzyme 5-alpha reductase. DHT is a more potent androgen that plays a crucial role in prostate growth and development. Choice A (cholesterol) is incorrect as it is not a product of testosterone conversion in the prostate. Choice B (estrogen) is incorrect as testosterone is not directly converted to estrogen in the prostate. Choice C (progesterone) is incorrect as progesterone is not the main product of testosterone conversion in the prostate.
Question 5 of 5
The superior portion of the uterus is the _____.
Correct Answer: C
Rationale: The correct answer is C: fundus. The fundus is the superior portion of the uterus, located above the entry point of the fallopian tubes. It is the part of the uterus where the fertilized egg implants and grows during pregnancy. The body of the uterus (choice A) is the main central portion, the cervix (choice B) is the lower narrow part that connects to the vagina, and the infundibulum (choice D) is a part of the fallopian tube, not the uterus. Thus, the fundus is the correct choice as it specifically refers to the superior portion of the uterus.
