Nursing Elites

1. Where does the ovum receive the sperm?

• A. Animal pole
• B. Vegetal pole
• C. Zona pellucida
• D. None of the above

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.

2. Causes of metrorrhagia include:

• A. Cervical carcinoma
• B. Uterine polyp
• C. Cervical endometriosis
• D. Infections like Chlamydia

Correct answer: A

Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.

3. Legislation allowing nursing staff to provide contraceptives has resulted in all of the following EXCEPT:

• A. More nursing staff have been trained to provide family planning services
• B. Many population and family planning organizations have emerged
• C. Enhanced implementation of population and family planning programs
• D. Male involvement in family planning services

Correct answer: D

Rationale: The correct answer is D. Male involvement in family planning services has not significantly resulted from legislation allowing nursing staff to provide contraceptives. While legislation has led to more nursing staff being trained, the emergence of population and family planning organizations, and enhanced implementation of programs, it has not directly impacted male involvement in family planning.

4. What type of epithelium lines the urinary bladder?

• A. Transitional epithelium.
• B. Stratified epithelium.
• C. Glandular tissue.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Transitional epithelium. The urinary bladder is lined with transitional epithelium, a specialized type of epithelial tissue that can stretch and recoil to accommodate changes in volume as the bladder fills and empties. Stratified epithelium (choice B) is not the main lining of the urinary bladder and is found in other areas like the skin. Glandular tissue (choice C) is responsible for producing secretions and is not typically found lining the urinary bladder. Endometrium (choice D) is the inner lining of the uterus and is not present in the urinary bladder.

5. What is the content of the acrosome?

• A. Lipids
• B. Hormones
• C. Digestive enzymes
• D. None of the above

Correct answer: C

Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.
