Effects of preeclampsia on the reproductive system include

Correct Answer: D

Rationale: The correct answer is D because preeclampsia can lead to poor placental anchorage, which results in reduced blood flow to the placenta, leading to severe infarction. This can cause adverse effects on the fetus and the mother. Choice A is incorrect because infarcts and placental abruption are not specific effects of preeclampsia on the reproductive system. Choice B is incorrect because lowered vaginal discharge pH and hemorrhage are not typical effects of preeclampsia. Choice C is incorrect because congestive cardiac failure and fetal hypoxia are not direct effects of preeclampsia on the reproductive system.

Correct Answer: C

Rationale: The correct answer is C because culture and level of education can significantly impact how women perceive and react to labor pain. Culture shapes beliefs, norms, and attitudes towards pain, influencing coping mechanisms. Education can enhance understanding of pain management techniques. Option A lacks specificity on how preparedness and fatigue affect perception. Option B oversimplifies by only considering culture and age. Option D overlooks the influence of education and focuses solely on anxiety and number of deliveries.

Correct Answer: B

Rationale: The correct answer is B: Low acidity levels which favor growth of candida albicans. During pregnancy, hormonal changes can lead to increased vaginal pH, creating a more alkaline environment that promotes the growth of candida albicans, causing vulvovaginitis. Choice A is incorrect as E. coli thrives in alkaline environments. Choice C, existing chronic hypertension, is unrelated to the development of vulvovaginitis. Choice D, lowered osmotic pressure, does not directly influence the growth of candida albicans.

Correct Answer: A

Rationale: The correct answer is A because monozygotic twins, also known as identical twins, develop from a single fertilized egg and share the same genetic material. This results in them always being of the same sex. Choice B is incorrect because fingerprint patterns are not solely determined by genetics. Choice C is incorrect because monozygotic twins will have the same blood group since they share the same DNA. Choice D is incorrect because superfetation, the fertilization of multiple eggs at different times during the same pregnancy, is not common in monozygotic twins.

Correct Answer: B

Rationale: The correct answer is B: Face presentation. Vaginal delivery is possible in face presentation as the fetus is in a position where the face is presenting first, allowing for delivery. In this presentation, the chin is usually tucked onto the chest, making it easier for the baby's head to pass through the birth canal. A: Brow presentation is incorrect because it indicates the baby's head is extended slightly, making it more difficult for vaginal delivery. C: Shoulder presentation is incorrect as it can lead to a shoulder dystocia, making vaginal delivery dangerous and difficult. D: Unstable lie is incorrect because it refers to the baby being in a transverse position, making vaginal delivery impossible without intervention.
