Midwifery Exam Questions and Answers PDF

Correct Answer: D

Rationale: The correct answer is D: 3000 ml. Polyhydramnios is diagnosed when the amniotic fluid volume exceeds 2000 to 3000 ml. This is because amniotic fluid serves important functions in protecting the fetus and aiding in fetal movements. Having an excessively high volume can lead to complications such as preterm labor, fetal malpresentation, and placental abruption. Choices A, B, and C are incorrect as they do not fall within the range typically used to diagnose polyhydramnios. A: 1500 ml and C: 1900 ml are below the threshold, while B: 2500 ml is at the lower end but still not exceeding the diagnostic range for polyhydramnios.

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: 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: 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: B

Rationale: The correct answer is B: Correct dehydration. Acute pyelonephritis can lead to dehydration due to fever, vomiting, and decreased fluid intake. High fluid intake helps correct dehydration by maintaining adequate fluid balance and preventing further complications. Increasing urine output (choice D) is a consequence of correcting dehydration. Promoting enough rest (choice A) is important but not the primary reason for advising high fluid intake. Relief of irritability (choice C) is not directly related to the management of acute pyelonephritis.
