Outline four (4) causes of obstructed labour:
- A. Fetal macrosomia
- B. Malpresentation
- C. Pelvic abnormalities
- D. All of the above
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.

TB in pregnancy predisposes a mother to premature labour due to
- A. Poor maternal appetite
- B. Severe anaemia experienced
- C. Adverse reactions of anti-TB drugs
- D. The fever experienced
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.
Three (3) complications of breech presentation:
- A. Prolonged labor, umbilical cord prolapse, shoulder dystocia
- B. Cesarean delivery, fetal distress, uterine rupture
- C. Preeclampsia, gestational diabetes, low birth weight
- D. All of the above
Correct Answer: A
Rationale: Rationale: Breech presentation increases risks during childbirth. Prolonged labor is common due to the position of the baby. Umbilical cord prolapse occurs when the cord slips through the cervix before the baby, leading to oxygen deprivation. Shoulder dystocia happens when the baby's shoulders get stuck during delivery. Choice A is correct as it directly relates to complications of breech presentation. Choices B, C, and D are incorrect as they do not specifically address the complications associated with breech presentation. Cesarean delivery is often recommended for breech presentation to avoid complications. Uterine rupture is a rare but severe complication that is not directly caused by breech presentation. Preeclampsia, gestational diabetes, and low birth weight are not commonly associated with breech presentation. Therefore, choice A is the correct answer.
Neoadjuvant chemotherapy treatment for cancer is given to facilitate surgical resection. When the outcomes of cancer therapies are evaluated, the terms complete response and partial response often are used. Partial response means that
- A. 50% of the patients treated with a given regimen demonstrate remission
- B. 50% of the patients treated survive to the 5-year point
- C. The tumor mass has reduced by > 50%
- D. In 50% of cases, the tumor converts from unresectable to resectable
Correct Answer: D
Rationale: The correct answer is D because in the context of neoadjuvant chemotherapy, a partial response means converting an unresectable tumor to a resectable one. This is crucial as it allows for successful surgical removal of the tumor. Choices A, B, and C do not accurately define partial response in the context of cancer therapy. A, stating 50% of patients demonstrating remission, is not specific to the change in resectability. B, mentioning 50% survival at 5 years, is more related to overall survival rather than the response to treatment. C, stating a reduction in tumor mass by >50%, does not necessarily imply a change in resectability status. Therefore, option D is the most appropriate definition of partial response in the given scenario.
The recommended number of chest compressions for neonatal resuscitation is
- A. 60 compressions coordinated with 30 breaths per minute
- B. 3 compressions coordinated with 1 breath per minute
- C. 1 compression coordinated with 3 breaths per minute
- D. 90 compressions coordinated with 30 breaths per minute
Correct Answer: A
Rationale: The correct answer is A: 60 compressions coordinated with 30 breaths per minute. In neonatal resuscitation, the recommended compression-to-ventilation ratio is 3:1. This means 3 compressions are given followed by 1 breath. With a target compression rate of 120 per minute, this translates to 60 compressions coordinated with 30 breaths per minute. Each compression should be at a depth of about one-third the anterior-posterior diameter of the chest. This ratio and rate are crucial for maintaining adequate circulation and oxygenation during neonatal resuscitation.
Choice B: 3 compressions coordinated with 1 breath per minute is too slow and would not provide enough support for the neonate's circulation.
Choice C: 1 compression coordinated with 3 breaths per minute would not provide sufficient compressions to maintain circulation.
Choice D: 90 compressions coordinated with 30 breaths per minute would result in an incorrect compression-to-vent
How can Braxton Hicks contractions be differentiated from true labor?
- A. By timing
- B. By intensity
- C. By duration
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D - All of the above. Braxton Hicks contractions can be differentiated from true labor by timing, intensity, and duration. Timing refers to the regularity of contractions, intensity relates to the strength of contractions, and duration indicates how long contractions last. By considering all three factors together, one can determine whether contractions are Braxton Hicks (practice contractions) or true labor contractions. Choices A, B, and C alone provide only partial information, which may lead to misinterpretation. Therefore, choosing all three factors collectively (D) is essential for accurate differentiation.
