Midwifery Exam Practice Questions Questions
Question 1 of 9
What is a common cause of oligohydramnios during pregnancy?
Correct Answer: C
Rationale: The correct answer is C: Premature rupture of membranes. Oligohydramnios is a condition characterized by low levels of amniotic fluid which can be caused by the premature rupture of membranes, leading to the leakage of amniotic fluid. This condition can result in various complications such as fetal growth restriction and compression of the umbilical cord. Maternal hypertension (choice A) is not a direct cause of oligohydramnios. Multiple gestations (choice B) may lead to polyhydramnios (excessive amniotic fluid) rather than oligohydramnios. Fetal macrosomia (choice D) is associated with increased amniotic fluid levels rather than decreased levels seen in oligohydramnios.
Question 2 of 9
How does the maternal microbiome influence the health of the fetus during pregnancy?
Correct Answer: B
Rationale: The correct answer is B: By altering immune development. The maternal microbiome plays a crucial role in shaping the fetal immune system during pregnancy. Microbes in the mother's body can influence the development of the fetus's immune system through various mechanisms, such as immune cells crossing the placenta. This interaction helps the fetus develop tolerance to maternal antigens. Choice A (By increasing fetal weight) is incorrect because the maternal microbiome's influence is not primarily related to weight gain. Choice C (By reducing placental oxygen levels) is incorrect as it does not directly relate to the immune system development. Choice D (By enhancing amniotic fluid) is incorrect as the main influence is on the immune system rather than amniotic fluid enhancement.
Question 3 of 9
Prior to taking a patient for an emergency cesarean section, it is MOST important to assess that:
Correct Answer: C
Rationale: The correct answer is C because establishing an intravenous line is essential for immediate access to administer fluids, medications, and blood products during the emergency cesarean section. This step ensures that the patient's vital signs can be supported, and any emergent interventions can be readily delivered. A: While informed consent is important, in an emergency situation, the priority is to ensure the patient's immediate medical needs are met. B: Inserting a Foley's catheter may be necessary during the procedure, but it is not the most critical assessment prior to the cesarean section. D: Shaving the perineal area is not a priority in an emergency situation and may be done during the preparation for surgery.
Question 4 of 9
A condition of trial of scar is
Correct Answer: C
Rationale: Rationale for Correct Answer (C): A trial of scar is indicated when a woman has had no more than two previous caesarean sections. This is because the risk of uterine rupture increases with each subsequent caesarean section due to scar tissue weakening. Limiting the number of previous scars reduces this risk. Therefore, option C is correct. Summary of Incorrect Choices: A: Estimated fetal weight is not a determining factor for a trial of scar. B: Availability of a level one hospital nearby is important for emergency situations but not a criteria for trial of scar. D: Adequate pelvis with true conjugate 10.5cm is important for vaginal delivery but not a specific requirement for a trial of scar.
Question 5 of 9
Outline four (4) causes of obstructed labour:
Correct Answer: D
Rationale: The correct answer is D, "All of the above." Fetal macrosomia, malpresentation, and pelvic abnormalities are all known causes of obstructed labor. Fetal macrosomia refers to a large baby, which can lead to difficulty in passing through the birth canal. Malpresentation occurs when the baby is not positioned optimally for delivery, such as breech or transverse positions. Pelvic abnormalities, such as a contracted pelvis, can impede the baby's passage during labor. Therefore, selecting option D is appropriate as it encompasses all the major causes of obstructed labor. Choices A, B, and C are not individually comprehensive enough to cover all potential causes of obstructed labor.
Question 6 of 9
Mother-to-child transmission of TB organisms never occurs during labor.
Correct Answer: B
Rationale: Step 1: TB can be transmitted through respiratory droplets, not just during labor. Step 2: Mother with active TB can transmit the bacteria to the child during childbirth. Step 3: Therefore, the statement that mother-to-child transmission never occurs during labor is false. Summary: Choice B is correct because TB transmission can occur during labor, making Choice A incorrect. Choices C and D are irrelevant.
Question 7 of 9
What is the significance of skin-to-skin contact after birth?
Correct Answer: D
Rationale: The correct answer is D because skin-to-skin contact after birth offers multiple benefits. Firstly, it helps stabilize the baby's temperature by utilizing the parent's body heat. Secondly, it promotes bonding between the parent and baby through physical closeness and touch. Finally, it can regulate the baby's heartbeat by providing a calming and reassuring environment. Therefore, all of the above choices are correct in highlighting the significance of skin-to-skin contact after birth.
Question 8 of 9
TB in pregnancy predisposes a mother to premature labour due to
Correct Answer: D
Rationale: The correct answer is D. TB in pregnancy can lead to premature labor due to the fever experienced. Fever increases the risk of premature labor by triggering uterine contractions. Poor maternal appetite (A) and severe anemia (B) may impact the mother's health but are not directly linked to premature labor. Adverse reactions of anti-TB drugs (C) could potentially affect the mother's health but are not a direct cause of premature labor.
Question 9 of 9
The factor indicative of an abnormal labour pattern on vaginal examination is
Correct Answer: C
Rationale: Step 1: In normal labor, the cervix undergoes effacement and dilation. Step 2: A short and thin cervical canal indicates progression towards labor. Step 3: Long and thick cervical canal suggests a delay in labor progress. Step 4: Choice C, short and thin cervical canal, is indicative of abnormal labor. Summary: A, B, and D do not reflect changes in the cervix seen in labor, making them incorrect choices.
