Which of the following is highly associated with preterm babies?

Correct Answer: C

Rationale: The correct answer is C: Multiple gestation. Preterm birth is more common in multiple gestation pregnancies due to the increased strain on the mother's uterus and cervix. This can lead to early labor and delivery. Social habits (choice A) and genetic factors (choice B) may play a role in preterm birth but are not highly associated. Chronic conditions (choice D) can also contribute to preterm birth, but multiple gestation is a stronger predictor.

Correct Answer: D

Rationale: Step-by-step rationale for why D is correct: 1. Hyperemesis gravidarum is severe nausea and vomiting during pregnancy. 2. Prolonged vomiting can lead to electrolyte imbalances and nutritional deficiencies. 3. Vitamin B deficiency, specifically thiamine, can result in Wernicke’s encephalopathy. 4. Mallory-Weiss syndrome can occur due to repeated retching and vomiting. 5. Therefore, hyperemesis gravidarum can lead to both Wernicke’s encephalopathy and Mallory-Weiss syndrome. Summary: A: Placenta praevia is related to abnormal placental placement, not vomiting. B: Hypertensive disorders are associated with high blood pressure, not vomiting-related complications. C: Vitamin B deficiency can lead to Wernicke’s encephalopathy but is not directly caused by hyperemesis gravidarum.

Correct Answer: B

Rationale: The correct answer is B: FALSE. In mild preeclampsia, the mother may have symptoms such as mild hypertension, proteinuria, and swelling. This contradicts the statement that the mother has no complaints. Choice A is incorrect because it inaccurately states that the mother has no complaints. Choices C and D are not applicable as they do not provide any relevant information to address the question.

Correct Answer: A

Rationale: The correct answer is A because folic acid supplementation plays a crucial role in promoting spinal cord closure during fetal development, preventing neural tube defects. Folic acid helps in the formation of neural tube structures, ensuring proper closure and preventing defects like spina bifida. Choices B, C, and D are incorrect as preventing infections, enhancing fetal growth, and regulating blood sugar levels are not direct mechanisms through which folic acid prevents neural tube defects.

Correct Answer: A

Rationale: The correct answer is A: A temperature of 101.5°F. A fever indicates an inflammatory response, which could be due to a complication like cholecystitis or cholangitis. Elevated leukocyte count (choice B) supports infection but is not as specific as a fever. Palpable gallbladder (choice C) may suggest inflammation but not necessarily a complication. A positive Murphy's sign (choice D) is indicative of gallbladder inflammation but does not directly indicate a complication requiring surgical evaluation.

Correct Answer: A

Rationale: The presenting diameter in brow presentation is Submentobregmatic (choice A) because it refers to the distance from the submentum (chin) to the bregma (anterior fontanelle). This is the appropriate measurement for the brow presentation as the brow is the prominent part between the forehead and the chin. Choice B (Suboccipitofrontal) is incorrect because it refers to the distance from the subocciput to the frontal bone, which is not relevant to brow presentation. Choice C (Occipitalfrontal) is incorrect because it describes the distance from the occiput to the frontal bone, which again is not specific to brow presentation. Choice D (Mentovertical) is incorrect as it denotes the distance from the chin to the vertex, which is not the relevant measurement for brow presentation.

Correct Answer: C

Rationale: The correct answer is C: 4 hours. This is based on the definition of prolonged second stage in nulliparous women, which is labor lasting more than 4 hours. This duration is considered abnormal and may lead to increased risk of maternal and fetal complications. Choice A (1 hour) is too short and does not meet the criteria for prolonged second stage. Choice B (2 hours) is also insufficient based on the established timeframe. Choice D (8 hours) exceeds the duration for prolonged second stage, indicating a more advanced stage of labor. Therefore, the most appropriate and accurate timeframe for prolonged second stage in nulliparous women is 4 hours.

Correct Answer: D

Rationale: The correct answer is D (All of the above) because during pregnancy, UTI symptoms include painful urination, increased frequency of urination, and lower abdominal pain. Painful urination is a common symptom due to inflammation of the urinary tract. Increased frequency of urination is caused by the pressure of the growing uterus on the bladder. Lower abdominal pain can also occur due to the infection. Therefore, all these symptoms are indicative of a UTI during pregnancy. Other choices are incorrect as they do not encompass the comprehensive range of symptoms typically seen in a UTI during pregnancy.

Correct Answer: D

Rationale: Correct Answer: D. Some form of vagotomy Rationale: 1. Vagotomy is a surgical procedure that involves cutting the vagus nerve to reduce acid production in the stomach, which can help in treating ulcers. 2. Vagotomy is often recommended when ulcers are refractory to medical therapy, making it an appropriate surgical option. 3. Lifelong vitamin D replacement (A) is not typically necessary for ulcer treatment. Excision of the ulcer (B) is not a common treatment and does not address the underlying cause. Eating smaller meals (C) may help manage symptoms but is not a surgical option for refractory ulcers.
