D – Pineal region tumors cause obstructive hydrocephalus due to their proximity to the third ventricle.E – Endothelial tight junctions’ permeability is increased in response to injury and inflammation, allowing migration of white blood cells and friends to the site of injury.Ovarian carcinoid is highly unlikely to show up on your test, but if it did, it would likely present with a classic carcinoid syndrome. Teratomas are oddballs that typically have fat, hair, teeth, etc. Granulosa cell tumors, on the other hand, sometimes produce estrogen (which can lead to precocious puberty in young girls but otherwise may be occult). Leydig cell tumors aren’t always physiologically active, but those that are can cause masculinization. Patients with cancer are hypercoagulable. That’s why he came to the ER in the first sentence and what the ultrasound shows at the end. The issue of the day is that he has a DVT. B – Don’t let them blind you with this patient’s misery.There is no randomization as there is only a single treatment group. If you know you are getting a drug, then you are not blinded: it’s an open-label trial. C – This is obviously a clinical trial.Logically, resting muscle requires less energy (and thus less need for fatty acid breakdown) than active muscle. A – Malonyl-CoA inhibits the rate-limiting step in the beta-oxidation of fatty acid.T-cell CD28 activation through binding CD80 (part of the B7 group) on the APC is the dominant interaction in T-cell hypersensitivities/allergies.* B – Contract dermatitis is a type IV (T-cell mediated) hypersensitivity.And yes, even someone who uses and/or is dependent on illicit drugs should also receive narcotics to control pain. (Very) short-term use (immediately post-surgical) does not lead to long-term dependence (or so people have thought…). A – Narcotic use for acutely painful conditions is both reasonable and important.C – Serum sickness! A type III (immune complex) hypersensitivity.Joint hemorrhage (hemarthrosis), nail bed hemorrhage, and frank visceral hematomas are more commonly seen in hemophiliacs.* DVT (A) is the opposite problem, a thrombophilia.

Petechiae are common in thrombocytopenia.

C – His leukocyte count is normal, so he’s not at risk for opportunistic infection, but his platelets are low, placing him at risk of bleeding.

It decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. Underlying etiology in this patient is renal failure (uremia). The heart cannot fill properly, preload decreases, hypotension and tachycardia ensue, fluid backup leads to elevated JVP.

A – Electrical alternans on boards means a big pericardial effusion (and usually cardiac tamponade physiology).

It’s given to at-risk Rh- moms at 28 weeks and at delivery.

C – The purpose of Rhogam is to bind to and remove the RhD antigens so that the mother does not form an immune response against the antigen in the fetus’ blood.

C – Acetylcholine increases after drug X, which is the same we’d expect if drug X were a cholinesterase inhibitor.

A – Intermittent hyperbilirubinemia/jaundice in an otherwise healthy individual is typical of Gilbert’s syndrome, which is caused by the decreased activity of UDP glucuronosyltransferase.

B – In addition to penicillin, the treatment paradigm for step viridans endocarditis also includes the aminoglycoside gentamicin, which binds to the 30S subunit and accelerates bacterial clearing/decreases treatment duration.*.

The asterisks (*) signifies a new question, of which there are 36. Last year’s 2019 set is available here, though it was almost entirely a repeat of the 2018 set explained here. (If you’re taking this in 2021, then see those explanations for updated questions #24 and 53) The official practice material page subsequently reverted back to the 2019 version, but as you can see the 2020 link remains live.

As always, the order here reflects that of the new PDF released in February 2020 (the “new” August 2020 pdf is the same). Another year, another set of explanations.
