    Thanks for the suggestion, @NikkiNikki ! Your explanation definitely makes sense. Did you select this answer in your version of the test, and it did not show up in the expanded feedback? That's the only way to know the correct answer is 100% D.
  12. NikkiNikki
    I guessed way to fast and selected whichever answer had WBC in it. Jumped the gun and got it wrong. Have you taken Step 2 already?

    I am having a hard time with this one (it's in block 3). I answered F, which was wrong. Thanks!

    A 72-year-old woman comes to the physician because of an increase in abdominal girth over the past 2
    months. She has had a 3.6-kg (8-lb) weight gain during this period despite being unable to finish any meal. She
    has one martini daily after her 3-mile walk. She underwent lumpectomy and radiation therapy for stage I breast
    cancer 4 years ago and has been treated with tamoxifen since then. Abdominal examination shows a fluid
    wave. Pelvic examination shows an 8-cm, fixed, nontender mass in the cul-de-sac. Laboratory studies show
    normal findings. Which of the following is the most appropriate next step in management?
    A) Intravenous albumin therapy
    B) Intravenous antibiotic therapy
    C) Intravenous cisplatin and paclitaxel therapy
    D) Oral angiotensin-converting enzyme (ACE) inhibitor therapy
    E) Oral spironolactone therapy
    F) Therapeutic paracentesis
    G) Exploratory laparotomy

    Great question, @tiniwink! The answer is G, ex-lap

    This question seems to have perplex several students I've spoken with. First off, we can tell she is having acites, and the main point of the question is to identify what is causing it. They tell you she has a a fixed mass in the cul-de-sac, which you should make you wonder, "what kind of OBGYN tumor is this?"

    The main knowledge gap is to know that ovarian masses can present with ascites, and that an ovarian mass of 8-cm (which is quite large!) needs to be removed asap. There is a high likelihood that this is cancer, and it needs to be staged, which can only be accomplished with an ex-lap. Remember that we do NOT biopsy these masses (for risk of seeding among other reasons).

    She drinks only 1 martini a day (most med students drink more than that), so her ascites is likely not due to alcoholic liver disease. A therapeutic paracentesis might be an ok thought, but she's going to ultimately need surgery asap, so you should skip the paracentesis and go to surgery. Furthermore, we don't even know exactly how much fluid she has in her belly, something they should probably tell you if they want you to choose paracentesis. She has no signs of infection, and no other pertinent history pointing to anything else, which should help you eliminate other choices.

    Hope this helped!

    Hi thank you for posting these, super helpful!
    For Block 2 part 1 #4, I think the question you're missing is below.
    Q. Three days after hospitalization for treatment of severe muscle weakness secondary to Guillain-Barre syndrome, a 21-year old woman has a temperature of 39C (102.2F). Arterial blood gas analysis on 2 L/min of oxygen via nasal cannula shows pH 7.33, pCO2 32 mmHg, PO2 50 mmHg. An x-ray of the chest shows infiltrates in the middle and lower lobes. Bronchoscopy is performed; Gram stain of material obtained from the right main-stem bronchus shows numerous segmented neutrophils, gram-positive cocci, and gram-negative cocci and bacilli. Which of the following is most likely to have prevented her acute pulmonary symptoms?
    A) Elevation of the head of the bed
    B) Nasogastric suction
    C) Administration of intravenous cephalosporin
    D) Administration of intravenous cimetidine
    E) Administration of subcutaneous heparin

    Anyone know the answer? It's NOT nasogastric suction. I'm thinking elevation of the head to prevent aspiration pneumonia?
