Midwifery Exam Questions and Answers PDF

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.

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: Face presentation. Vaginal delivery is possible in face presentation as the baby's head is extended, allowing for descent through the birth canal. Brow presentation (A) and shoulder presentation (C) may require cesarean delivery due to the atypical presentation of the baby. Unstable lie (D) refers to the baby being in a transverse position, which also necessitates a cesarean section. Face presentation is the only option where vaginal delivery may be possible due to the extended position of the baby's head.

Correct Answer: A

Rationale: The correct answer is A because occipito-posterior position can lead to prolonged labor due to poor fetal positioning, causing maternal back pain. This can result in fetal distress as the baby may have difficulty descending through the birth canal. Postpartum hemorrhage, uterine rupture, fetal death (choices B and C) are not typically associated with occipito-posterior position. Therefore, choice A is the most appropriate answer.

Correct Answer: C

Rationale: The correct answer is C: Majority are classified as secondary face presentation. In face presentation, the fetal head is hyperextended, presenting the face to the birth canal. Primary face presentation is rare. The bi-parietal diameter is not the presenting diameter in face presentation, as it is in vertex presentation. Locating the anterior fontanelle is not diagnostic of face presentation, as the fontanelles can be difficult to palpate during labor. Therefore, the correct statement is that the majority of face presentations are classified as secondary face presentation.
