1. _______ 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.

2. Risk of endometrial hyperplasia is greatest in individuals who do not menstruate for at least _____ months and require immediate referral:

• A. 2 months
• B. 3 months
• C. 4 months
• D. 5 months

Correct answer: C

Rationale: The correct answer is C: '4 months.' The risk of endometrial hyperplasia is highest in individuals who do not menstruate for at least 4 months. This prolonged exposure to unopposed estrogen can lead to endometrial hyperplasia. Choices A, B, and D are incorrect because the risk is greatest after at least 4 months of not menstruating, not 2, 3, or 5 months.

3. A client 12 weeks pregnant comes to the emergency department with abdominal cramping and moderate vaginal bleeding. Speculum examination reveals 2 to 3 cm cervical dilation. The nurse would document these findings as which of the following?

• A. Threatened abortion
• B. Inevitable abortion
• C. Complete abortion
• D. Missed abortion

Correct answer: B

Rationale: The nurse would document these findings as an inevitable abortion. Inevitable abortion is characterized by cervical dilation with or without rupture of membranes and is associated with moderate to heavy vaginal bleeding. 'Threatened abortion' (choice A) refers to vaginal bleeding with a closed cervical os and no tissue passage. 'Complete abortion' (choice C) involves the passage of all products of conception. 'Missed abortion' (choice D) is the retention of a failed intrauterine pregnancy for an extended period without symptoms.

4. The weight of the non-pregnant uterus is approximately ___________grams.

• A. 57
• B. 80
• C. 66
• D. 71

Correct answer: B

Rationale: The correct answer is B: 80. The non-pregnant uterus typically weighs around 80 grams. This weight may vary slightly among individuals, but 80 grams is a commonly accepted average. Choices A, C, and D are incorrect as they do not reflect the typical weight of the non-pregnant uterus. It is important to remember this approximate weight for medical reference and understanding of normal anatomical variations.

5. Discuss the anatomical/physiological changes in pregnancy under the following: Cardiovascular system

• A. The heart is displaced upward and to the left by the enlarging uterus, cardiac capacity increases, and blood pressure declines slightly.
• B. The heart is displaced downward and to the right, and blood pressure increases.
• C. The cardiovascular system remains unchanged during pregnancy.
• D. Cardiovascular changes include increased peripheral resistance and reduced cardiac output.

Correct answer: A

Rationale: During pregnancy, the cardiovascular system undergoes changes such as the heart being displaced upward and to the left by the enlarging uterus, increased cardiac capacity, and a slight decline in blood pressure. Choice B is incorrect as the heart is displaced upwards, not downwards, and blood pressure typically decreases slightly. Choice C is incorrect as the cardiovascular system does undergo changes during pregnancy. Choice D is incorrect as cardiovascular changes in pregnancy involve increased cardiac output rather than reduced output.
