1. What is a characteristic of threatening abortion?

• A. Os open.
• B. Firm contracted uterus.
• C. Heavy bleeding.
• D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

2. Inevitable abortion occurs when:

• A. The ovum dies in utero and the decidua capsularis remains intact.
• B. The cervix is open, and the products of conception are about to be expelled.
• C. The products of conception are expelled before the 20th week of gestation.
• D. The fetus dies and is expelled in the first trimester.

Correct answer: B

Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.

3. Which of the following is subsidiary uterine support?

• A. Suspensory ligament
• B. Cardinal ligament
• C. Transcervical ligament
• D. Maklouf ligament

Correct answer: B

Rationale: The correct answer is B: Cardinal ligament. The cardinal ligament is a primary uterine support structure that helps to anchor the uterus in place. The suspensory ligament also provides support for the uterus but is not considered a subsidiary uterine support. The transcervical ligament does not exist in anatomical terminology. The Maklouf ligament is a fictitious term and not recognized as a subsidiary uterine support structure.

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. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.
