Identify the CORRECT strategy to achieve external fertilization.

Correct Answer: C

Rationale: The correct strategy for external fertilization is to have eggs and sperm shed simultaneously into water. This allows the gametes to meet and fertilize outside of the organism's body. This method is effective in aquatic environments where the chances of gametes coming into contact are increased. Choice A is incorrect as it describes internal fertilization. Choice B is irrelevant to the process of external fertilization. Choice D is incorrect as the frequency of egg and sperm release does not determine the success of external fertilization.

Correct Answer: A

Rationale: The correct answer is A: Assist the client in sitting up after the procedure. This is important to prevent complications like vasovagal response or fainting due to sudden positional changes. Sitting up slowly helps stabilize blood pressure and prevent dizziness. B: Providing a pad for dye stains is not the most important action as it is a minor concern compared to client safety post-procedure. C: Taking antibiotics has no direct relevance to the hysterosalpingogram procedure, so it is not the most important action. D: Informing the client about potential shoulder pain is helpful, but ensuring immediate safety by assisting the client in sitting up takes precedence.

Correct Answer: C

Rationale: The correct answer is C: acrosome. Lysosomal-like enzymes are found in the acrosome of sperm cells, where they help in breaking down the outer layers of the egg during fertilization. Sertoli cells (A) provide nourishment and support for developing sperm cells. The sperm head (B) contains genetic material but not lysosomal-like enzymes. The sperm tail (D) is responsible for movement and does not contain lysosomal-like enzymes. Therefore, the acrosome (C) is the structure that specifically houses these enzymes for the fertilization process.

Correct Answer: C

Rationale: Step 1: ICSH stands for interstitial cell-stimulating hormone. Step 2: Interstitial cells are found in the testes and produce testosterone. Step 3: ICSH targets these interstitial cells to stimulate testosterone production. Step 4: Therefore, the correct answer is C: interstitial cells. Summary: A, B, and D are incorrect as ICSH does not target the prostate, seminiferous tubule, or seminal vesicle.

Correct Answer: B

Rationale: The correct answer is B: myometrium. The myometrium is the muscular layer of the uterus responsible for contractions during labor and menstruation. It is the largest component of the uterus by weight due to its thick and muscular nature. The broad ligament (A) is a sheet of peritoneum that supports the uterus and other pelvic organs. The round ligament (C) helps support the uterus and is not as significant in weight compared to the myometrium. The endometrium (D) is the inner lining of the uterus that thickens and sheds during the menstrual cycle, but it is not the largest component by weight.
