A characteristic of monozygotic twins is that
- A. They are always of the same sex
- B. They share a similar fingerprint pattern
- C. They have different blood groups
- D. Superfetation is a common finding
Correct Answer: A
Rationale: The correct answer is A: They are always of the same sex. This is because monozygotic twins, also known as identical twins, develop from a single fertilized egg that splits into two embryos. As a result, they share the same genetic material and are always of the same sex.
Choice B is incorrect because fingerprint patterns are not determined by genetics and can vary even between identical twins. Choice C is incorrect because monozygotic twins share the same blood type since they have the same genetic makeup. Choice D is incorrect as superfetation, the occurrence of multiple pregnancies in the same uterus but from different ovulations, is extremely rare and not a common finding in monozygotic twins.

Perception and reaction to labor pain is highly influenced by
- A. Labor preparedness and fatigue
- B. Culture and level of education
- C. Culture and age of the woman
- D. Number of deliveries and anxiety
Correct Answer: B
Rationale: The correct answer is B - Culture and level of education. Culture influences beliefs about pain and coping mechanisms. Education can affect understanding of pain and pain management techniques. Labor preparedness and fatigue (A) may impact pain perception but are not as influential. Age (C) alone does not determine pain perception. Number of deliveries and anxiety (D) can play a role but are not as significant as culture and education.
A condition of trial of scar is
- A. Estimated fetal weight of less than 3600g
- B. Availability of a level one hospital nearby
- C. Not more than two previous caesarean section scars
- D. An adequate pelvis with true conjugate 10.5cm
Correct Answer: C
Rationale: The correct answer is C: Not more than two previous caesarean section scars. This is because a trial of scar refers to a trial of labor in a woman who has had previous cesarean sections. The guideline typically recommends that a trial of scar should be considered in women with no more than two previous cesarean section scars to reduce the risk of uterine rupture. Choices A, B, and D are incorrect because the estimated fetal weight, availability of a level one hospital, and pelvis size are not specific criteria used to determine eligibility for a trial of scar.
Clinical features of facial palsy are
- A. Inability to feed and excessive cry
- B. Reduced facial movement and irritability
- C. Excessively dry eyeball and feeding difficulties
- D. Eyes permanently open and no facial movement
Correct Answer: B
Rationale: The correct answer is B because reduced facial movement is a key clinical feature of facial palsy. This can lead to difficulty in making facial expressions, closing the eye on the affected side, and drooping of the mouth. Irritability may also occur due to discomfort or difficulty in communication.
Choice A is incorrect because inability to feed and excessive cry are not typical features of facial palsy. Choice C is incorrect as excessively dry eyeball and feeding difficulties are not commonly associated with facial palsy. Choice D is incorrect as eyes being permanently open and no facial movement are not characteristic of facial palsy.
A patient admitted for management of sepsis is critically ill and wants to talk with a hospital representative about donating her organs if she dies. She has a fairly complex medical history that includes traumatic brain injury, breast cancer, and dialysis-dependent renal failure. The patient is advised that she is ineligible to donate due to her
- A. Renal failure
- B. Traumatic brain injury
- C. Gram negative infection
- D. Breast cancer
Correct Answer: D
Rationale: The correct answer is D: Breast cancer. The patient's breast cancer is the reason she is ineligible to donate organs. Breast cancer is a contraindication for organ donation due to the risk of cancer transmission to the recipient. Traumatic brain injury (choice B) and renal failure (choice A) are not absolute contraindications to organ donation. Gram-negative infection (choice C) may temporarily disqualify the patient but can be treated, unlike breast cancer. In summary, breast cancer poses the highest risk of organ recipient harm compared to the other medical conditions listed.
A medical/obstetric predisposing factor to puerperal sepsis includes
- A. Delivery by unskilled birth attendants
- B. Emergency cesarean section
- C. Poor personal hygiene
- D. Delay in care seeking
Correct Answer: B
Rationale: The correct answer is B: Emergency cesarean section. Emergency cesarean sections can increase the risk of puerperal sepsis due to the urgency of the procedure, which may lead to inadequate sterilization or contamination. Other choices are less directly associated with puerperal sepsis: A may increase the risk of infection, but not specifically puerperal sepsis. C relates to general hygiene practices and D focuses on delays in seeking care, which may affect treatment outcomes but are not direct predisposing factors to puerperal sepsis.
