Presence of a turtle’s sign is clearly indicative of
- A. Prolonged labor
- B. Occipito-posterior position
- C. Shoulder dystocia
- D. Shoulder presentation
Correct Answer: C
Rationale: The presence of a turtle sign during delivery is indicative of shoulder dystocia. This occurs when the baby's shoulders get stuck behind the mother's pelvic bones during delivery, leading to difficulty in delivering the baby's shoulders. The turtle sign refers to the retraction of the baby's head back into the birth canal after delivery of the head, resembling a turtle retracting into its shell. This sign is a clear indicator of shoulder dystocia. Choices A, B, and D are incorrect because prolonged labor, occipito-posterior position, and shoulder presentation do not specifically involve the retraction of the baby's head like in shoulder dystocia.

Clinical features of intracranial injury include:
- A. Limpness, bruises, and hypothermia
- B. Irritability, hypoxia, and paralysis
- C. Hypothermia, limpness, and irritability
- D. Hypocalcemia, paralysis, and hypoxia
Correct Answer: B
Rationale: The correct answer is B: Irritability, hypoxia, and paralysis. Intracranial injury can lead to neurological symptoms such as irritability due to brain inflammation, hypoxia from impaired oxygen delivery, and paralysis from damage to the brain or spinal cord. Limpness, bruises, and hypothermia (Option A) are not specific to intracranial injury. Hypothermia, limpness, and irritability (Option C) do not encompass the key neurological symptoms associated with intracranial injury. Hypocalcemia, paralysis, and hypoxia (Option D) include incorrect factors not typically seen in intracranial injury.
What are the risks of cesarean sections?
- A. Infection
- B. Blood loss
- C. Prolonged recovery
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D because all the choices (A, B, and C) are risks associated with cesarean sections. Infection can occur at the incision site, blood loss is a common concern during surgery, and cesarean sections typically have a longer recovery time compared to vaginal delivery. Therefore, all of these risks are potential complications of undergoing a cesarean section. The other choices (A, B, and C) are incorrect individually because they only represent a subset of the risks associated with cesarean sections, while choice D encompasses all potential risks.
R. R. is a 71-year-old female who presents with left lower quadrant pain that started out as cramping but has become more constant over the last day. She reports constipation over the last few days but admits that for as long as she can remember she has had variable bowel habits. Her vital signs are normal, but physical examination reveals some tenderness in the left lower quadrant. Which diagnostic test is most likely to support the leading differential diagnosis?
- A. CT scan with IV, oral, and rectal contrast
- B. CBC with WBC differential
- C. Colonoscopy
- D. Barium enema
Correct Answer: B
Rationale: The correct answer is B: CBC with WBC differential. This test can help rule out infectious causes of left lower quadrant pain, such as diverticulitis or colitis, by assessing for elevated white blood cell count and left shift. A CT scan (A) with contrast may be indicated if the patient's condition worsens or if initial tests are inconclusive. Colonoscopy (C) is more appropriate for evaluating chronic or intermittent abdominal pain, not acute symptoms. Barium enema (D) is an outdated test and not commonly used for diagnosing acute abdominal pain.
A major predisposing factor to cardiac disease in pregnancy includes
- A. Rheumatic heart disease
- B. Notable peripheral oedema
- C. Easy fatiguability
- D. Basal crepitation
Correct Answer: A
Rationale: The correct answer is A: Rheumatic heart disease. This is because rheumatic heart disease is a known risk factor for cardiac complications during pregnancy due to the strain pregnancy places on the heart. Choice B, notable peripheral edema, is a symptom of heart failure but not a predisposing factor. Choice C, easy fatiguability, is a non-specific symptom and not a direct predisposing factor. Choice D, basal crepitation, is a sign of possible lung pathology and not directly related to cardiac disease in pregnancy. Therefore, the correct answer is A as it directly relates to an increased risk of cardiac issues during pregnancy.
Surgical induction of labor refers to the use of
- A. Cytotec and mechanical cervical dilatation
- B. Sweeping of membranes and amniotomy
- C. Mechanical cervical dilatation and buscopan
- D. Artificial rupture of membranes and syntocinon
Correct Answer: B
Rationale: The correct answer is B: Sweeping of membranes and amniotomy.
1. Sweeping of membranes involves manually separating the amniotic sac from the lower part of the uterus, stimulating the release of prostaglandins to induce labor.
2. Amniotomy is the artificial rupture of membranes, which can accelerate labor by releasing amniotic fluid and initiating contractions.
3. These methods are commonly used for surgical induction of labor due to their effectiveness and minimal invasiveness compared to other options.
Incorrect choices:
A: Cytotec is a medication used for labor induction, but mechanical cervical dilatation is not a standard surgical method.
C: Buscopan is used for relaxation of smooth muscle and not commonly used for labor induction.
D: Syntocinon is a synthetic form of oxytocin used to induce or augment labor, but it is not typically used in surgical induction methods.
