A nurse and unlicensed assistive personnel (UAP) are helping a client during a hysterosalpingogram. Which action by the nurse is best delegated to the UAP?

Correct Answer: B

Rationale: The correct answer is B: Assisting the client into a lithotomy position. This task can be safely delegated to the UAP as it involves physically assisting the client into a specific position and does not require specialized nursing knowledge or assessment skills. The nurse should be available to provide guidance and supervision to ensure the safety and comfort of the client during the procedure. Choices A, C, and D involve tasks that require nursing assessment and critical thinking skills, which should be performed by the nurse. Witnessing the consent form (choice A) ensures proper documentation and understanding of the procedure. Asking about allergies to iodine or shellfish (choice C) is crucial to prevent adverse reactions during the procedure. Assessing for pelvic or shoulder pain after the study (choice D) is important to monitor for any potential complications post-procedure. These tasks are within the scope of nursing practice and should not be delegated to a UAP.

Correct Answer: A

Rationale: The correct sequence is A: Zygote - morula - 2 cells - 4 cells - 8 cells - blastula. After fertilization, the zygote undergoes cleavage to form the morula, which then divides into 2 cells, then 4 cells, and further into 8 cells. These cells then rearrange to form the blastula. This sequence aligns with the natural progression of post-fertilization cleavage in embryonic development. Choices B, C, and D are incorrect because they do not follow the correct chronological order of events in post-fertilization cleavage. In these sequences, the order of cell divisions is mixed up, leading to an inaccurate representation of the cleavage process. It is crucial to understand the logical progression of events in embryonic development to identify the correct sequence of post-fertilization cleavage.

Correct Answer: D

Rationale: Estrogen is known to stimulate ductal proliferation in the breast tissue as part of its role in breast development and maintenance. This is crucial for preparing the breast for potential pregnancy and lactation. The other choices are incorrect because estrogen does not directly cause cystic changes in the vagina, alter the pH of cervical mucus to become more alkaline, or specifically facilitate the growth of ovarian follicles. Estrogen plays a role in ovarian follicle development, but its main function in this context is to stimulate the growth and maturation of the follicles, not just facilitate their growth.

Correct Answer: C

Rationale: The correct answer is C: Bleeding from the vagina. This finding is concerning in a postmenopausal woman as it could indicate underlying serious conditions such as endometrial cancer. Immediate action is needed to investigate the cause and provide appropriate care. A: Vaginal dryness is common in postmenopausal women and can be managed with lubricants or hormone therapy. B: Not having a Pap test for 3 years is important for cervical cancer screening but does not require immediate action. D: Leakage of urine, while a concern, does not require immediate action as it is not directly related to a potentially life-threatening condition.

Correct Answer: B

Rationale: The correct answer is B: seminiferous tubules. Testicular cancer arises from the cells within the seminiferous tubules where sperm production occurs. These tubules are the most common site for testicular cancer to develop. The other choices are incorrect because testicular cancer typically does not originate from the scrotal sac (A), epididymis (C), or interstitial cells (D). The scrotal sac contains the testicles but does not produce cancer, the epididymis is a different structure involved in sperm maturation, and interstitial cells produce hormones rather than sperm.
