Correct Answer: A

Rationale: The correct answer is A: Unstable lie. After 36 weeks of gestation, the fetal lie should typically be consistent. An unstable lie refers to a situation where the fetal lie keeps changing position, indicating a potential complication. This can lead to difficulties during labor and delivery. Summary: B: Compound lie - Refers to a situation where the fetus is in an abnormal position, such as breech or transverse, alongside another part of the body presenting first. C: Multiple lie - Not a recognized medical term. D: Transverse lie - Refers to a situation where the fetus is positioned horizontally across the uterus, which can complicate delivery.

Correct Answer: A

Rationale: The correct answer is A: Footling. When a hand/foot lies alongside the presenting part, it indicates a footling presentation where the foot is presenting first. This is a type of breech presentation, where the baby's buttocks or feet come out first. A transverse presentation would mean the baby is lying sideways, and an unstable lie refers to the baby's position not being fixed. Therefore, the presence of a hand/foot alongside the presenting part specifically indicates a footling presentation, making choice A the correct answer.

Correct Answer: B

Rationale: The correct answer is B. Ordering hepatic ultrasound annually to follow progression is the appropriate response for hepatic hemangiomas. Biopsy is not recommended due to the risk of bleeding. Surgery is usually not required unless there are complications. Documenting the finding is important but does not address the need for monitoring. Ultrasound allows for non-invasive monitoring of the hemangiomas over time to assess for growth or complications, guiding further management if needed.

Correct Answer: C

Rationale: The correct answer is C: Improve fetal oxygenation. Oxygen at 4 liters/minute is given to increase oxygen levels which can help improve oxygenation to the fetus during a cord prolapse scenario. This can be crucial in preventing fetal distress and hypoxia. Explanation for Incorrect Choices: A: Relieve maternal distress - Oxygen is primarily given in this scenario to benefit the fetus, not to relieve maternal distress. B: Promote her relative rest - Oxygen is not administered to promote rest, but to address the immediate concern of fetal oxygenation. D: Achieve the effect of tocolysis - Oxygen does not have a role in tocolysis, which is the inhibition of uterine contractions.

Correct Answer: B

Rationale: The correct answer is B (GCS of 3 to 8 and hypotension) because hypotension is not a specific indication for intracranial pressure (ICP) monitoring according to the Brain Trauma Foundation guidelines. The rationale is that hypotension is a systemic issue affecting overall perfusion, whereas ICP monitoring is specifically for assessing intracranial dynamics. A, C, and D are incorrect choices because they all involve conditions that could potentially indicate increased intracranial pressure and the need for monitoring. A) Abnormal head CT indicates structural brain injury, C) age > 40 is a risk factor for poor outcomes after traumatic brain injury, and D) bradycardia can be a sign of increased ICP affecting brainstem function. Therefore, these conditions warrant ICP monitoring according to guidelines.
