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: A

Rationale: The correct answer is A: No further care, because the chest radiograph is negative. In this scenario, Jennifer has a positive PPD test with a 12-mm induration but a negative chest radiograph, indicating latent TB infection. The negative chest radiograph rules out active TB disease. As a result, Jennifer does not require further evaluation or treatment for active TB. The positive PPD alone does not warrant further investigations such as Quantiferon assay (B) or prophylactic therapy (C) as these are not indicated for latent TB infection without active disease. Beginning therapy for pulmonary TB (D) is unnecessary and potentially harmful as Jennifer does not have active TB. Thus, the correct course of action is to provide no further care based on the negative chest radiograph.

Correct Answer: B

Rationale: The correct answer is B: Presence of the Bandl's ring. This is indicative of an abnormal labor pattern as it may suggest a uterine rupture, which is a serious complication. Bandl's ring is a constriction ring formed between the upper and lower uterine segments due to excessive uterine contractions. It can lead to fetal distress and necessitate immediate medical intervention. A: Presence of the retraction ring is a normal phenomenon during labor, marking the boundary between the lower and upper uterine segments. C: Cervical canal short and thin can be a normal variation in labor and does not necessarily indicate an abnormal pattern. D: Vagina being warm and moist is a common physiological response during labor and does not provide information on the progress or abnormality of labor.

Correct Answer: D

Rationale: The correct answer is D because fetal indications for cesarean section typically involve situations where the baby cannot safely be delivered vaginally. Cephalo-pelvic disproportion means the baby's head is too large to pass through the mother's pelvis, necessitating a C-section. Impacted face presentation can result in difficulty during delivery, also requiring a C-section. Locked twins refer to a situation where the babies are unable to move past each other during delivery, further indicating the need for a C-section. Choices A, B, and C include some relevant indications for a C-section, but they do not encompass the full range of fetal indications like choice D does.
