Which one of the following features is indicative of an abnormal labour pattern?

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 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: A

Rationale: Grade 1 cardiac disease refers to early-stage or mild heart conditions that are not yet severe. Choice A, "Organic disease," is the correct answer as it encompasses a broad category of structural heart abnormalities. Mitral stenosis (B) and ventricular failure (C) are specific conditions that can be present in cardiac disease but do not represent the general term for grade 1. Vascular disease (D) primarily refers to conditions affecting blood vessels, not the heart itself. In summary, choice A is correct because it is a comprehensive term that includes various structural heart abnormalities typically found in grade 1 cardiac disease, while the other choices are either too specific or unrelated to the concept of grade 1 cardiac disease.

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.
