Correct Answer: D

Rationale: The correct answer is D: All of the above. High-risk pregnancies are associated with various complications, including preterm birth, gestational diabetes, and preeclampsia. Preterm birth can lead to developmental issues for the baby. Gestational diabetes affects the mother's and baby's health. Preeclampsia can result in high blood pressure and organ damage. Choosing D as the correct answer encompasses all these complications, highlighting the comprehensive nature of risks in high-risk pregnancies. Choices A, B, and C alone do not cover all the potential complications, making them individually incorrect.

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: C

Rationale: The correct answer is C: Fever. Physiologic stress ulcers are often associated with systemic stress response, leading to an increase in body temperature. Fever is an early sign of stress-related ulcers before other symptoms like epigastric pain or hemorrhage manifest. Change in mental status is more indicative of neurological issues rather than stress ulcers. Epigastric pain typically occurs after the ulcer has progressed, and hemorrhage is a severe complication of untreated stress ulcers.

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.
