What is the impact of maternal stress on fetal development?
- A. Can cause low birth weight
- B. Increases the risk of preterm labor
- C. Affects brain development
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D because maternal stress can indeed lead to low birth weight, increase the risk of preterm labor, and affect brain development in the fetus. Stress hormones can interfere with the placental function, affecting the transfer of nutrients to the fetus and leading to low birth weight. Stress can also trigger early contractions, potentially resulting in preterm labor. Furthermore, maternal stress can impact fetal brain development through the release of stress hormones that can alter the development of the fetal brain structures. Therefore, all of the choices (A, B, and C) are correct in demonstrating the impact of maternal stress on fetal development.

Which one of the following drugs when used by a pregnant woman is likely to lead to oligohydramnios?
- A. Diazepam
- B. Captopril
- C. Ampicillin
- D. Pethidine
Correct Answer: B
Rationale: The correct answer is B: Captopril. Captopril is an angiotensin-converting enzyme (ACE) inhibitor that can lead to oligohydramnios in pregnant women due to its effect on reducing fetal renal function. This can result in decreased amniotic fluid levels. Diazepam (A) is a benzodiazepine used for anxiety and is not associated with oligohydramnios. Ampicillin (C) is an antibiotic commonly used during pregnancy and does not cause oligohydramnios. Pethidine (D) is an opioid analgesic with no known association with oligohydramnios in pregnancy.
The term used to describe the situation whereby there is the presence of more than one part of the fetus on the pelvic brim at the onset of labor is
- A. Unstable lie
- B. Fetal malpresentation
- C. Fetal malposition
- D. Compound presentation
Correct Answer: D
Rationale: The correct answer is D: Compound presentation. This term refers to the situation where there is more than one part of the fetus on the pelvic brim at the onset of labor. This can include a hand or arm alongside the head or another body part. The other choices are incorrect because: A: Unstable lie refers to the fetus being in a transverse position. B: Fetal malpresentation indicates an abnormal presentation of the fetus, such as breech or transverse. C: Fetal malposition refers to the fetus being in a suboptimal position, like occiput posterior. Thus, the best choice is D as it specifically describes the scenario of multiple fetal parts on the pelvic brim.
Which one of the following statements is CORRECT with regards to precipitate delivery?
- A. May lead to uterine atony due to the moderate contractions experienced by client
- B. Puerperal sepsis is likely to result from unhygienic measures incorporated post-natally
- C. With adequate monitoring of the prenatal mother, precipitate delivery minimally recurs
- D. May cause cervical lacerations because of rapid descent and delivery of the baby
Correct Answer: D
Rationale: The correct answer is D because precipitate delivery, characterized by rapid descent and delivery of the baby, can cause cervical lacerations due to the fast and forceful passage of the baby through the birth canal. This can result in tearing of the cervical tissue. Choice A is incorrect because uterine atony is not typically associated with precipitate delivery. Choice B is incorrect as puerperal sepsis is not directly related to the speed of delivery. Choice C is incorrect as the occurrence of precipitate delivery does not guarantee reduced risk of recurrence with prenatal monitoring.
Delivery of the head in a breech presentation is usually accomplished through
- A. Lovset maneuver
- B. Burns Marshall Method
- C. Mauriceau-Smellie-Veit maneuver
- D. Reverse woodscrew maneuver
Correct Answer: C
Rationale: The Mauriceau-Smellie-Veit maneuver is the correct answer for delivering the head in a breech presentation. This maneuver involves applying pressure to the fetal head with the fingers in the mouth to flex the head, guiding it through the pelvis. This technique helps prevent hyperextension of the head and facilitates a safe delivery. The Lovset maneuver involves rotating the fetus to disengage the impacted shoulder, not for delivering the head. The Burns Marshall Method is used for delivering the aftercoming head in a breech presentation. The Reverse woodscrew maneuver is a technique to disimpact a shoulder dystocia, not for delivering the head in a breech presentation.
The lie is defined as unstable when it keeps varying after
- A. 36 weeks gestation
- B. 42 weeks gestation
- C. 38 weeks gestation
- D. 40 weeks gestation
Correct Answer: A
Rationale: The correct answer is A (36 weeks gestation) because at this stage, the fetal lie should stabilize into a consistent position, typically longitudinal. Before 36 weeks, fetal movement and position can vary frequently. Choices B, C, and D are incorrect as they are past the point where fetal lie should have stabilized. At 42 weeks gestation (Choice B), the baby is considered post-term, and fetal lie should have already been established. Similarly, Choices C (38 weeks) and D (40 weeks) fall within the expected range for fetal lie stabilization.
