Which question should the nurse ask when assessing a 60-yr-old patient who has a history of benign prostatic hyperplasia (BPH)?

Correct Answer: C

Rationale: The correct question to ask when assessing a 60-yr-old patient with a history of BPH is C: “Has there been a decrease in the force of your urinary stream?” This question is relevant as BPH commonly causes urinary symptoms like weak urinary stream. Asking about unusual discharge (A) is more relevant for assessing sexually transmitted infections. Inquiring about changes in sex life (B) and difficulty achieving an erection (D) are more related to erectile dysfunction, which may not be directly linked to BPH in this context.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Asexual reproduction involves the production of offspring from a single parent without the involvement of gametes or fertilization. - Fission: Organism splits into two or more parts, each regenerating into a new individual. - Fragmentation: Parent organism breaks into fragments, with each fragment developing into a new individual. - Budding: New individuals develop as outgrowths or buds from the parent organism. All these processes result in genetically identical offspring, making them examples of asexual reproduction.

Correct Answer: B

Rationale: The correct answer is B. Sperm are stored in the epididymis, ascend into the vas deferens prior to ejaculation, and are discharged from the penis through the urethra. The epididymis is where sperm mature and are stored. The vas deferens is the duct through which sperm travels from the epididymis to the urethra for ejaculation. The urethra is the final pathway for sperm to exit the body. Choices A, C, and D are incorrect because they do not follow the correct anatomical pathway of sperm from storage to ejaculation.

Correct Answer: C

Rationale: The correct answer is C because the luminal epithelium of efferent ductules is indeed irregular, which helps in absorption and modification of fluid. A, Leydig cells are located outside the seminiferous tubule. B, Sertoli cells provide nourishment and support to developing sperm cells but do not mature spermatids. D, Contraction of smooth muscle in vas deferens is stimulated by the parasympathetic nervous system, not the sympathetic.

Correct Answer: A

Rationale: The correct answer is A: Seminoma is the commonest pure testicular germ cell tumor. Seminoma is indeed the most common pure germ cell tumor of the testis, accounting for about 40-50% of cases. It typically presents in young adult males and has a good prognosis. Seminoma histologically consists of clear cytoplasmic glycogen and distinct cell borders. Choice B is incorrect as it seems to be incomplete. Choice C is incorrect as AFP (alpha-fetoprotein) increases in yolk sac tumors, not choriocarcinoma. Choice D is incorrect as Schiller-Duvall bodies are characteristic of embryonal carcinoma, not yolk sac tumors.
