Radiation causes damage by generating hydroxyl free radicals (Pathoma chapter 3 table). Therefore, if something minimizes the damage of radiation, it has to inhibit free radical formation.

The way I approached this problem was, schizophrenia doesn't have a clear pattern of inheritance. Among the option choices, only Type 1 DM doesn't have a clear inheritance pattern (eg: CF is auto recessive, Fragile X is XD, and so on).

karthvee  lol same here

This question is describing terminal insomnia, which is common either in MDD or normal aging. Out of those two MDD is the only thing in option choice. Plus, old age is a risk factor for MDD.

Even though the question does not describe 5 symptoms needed to diagnose MDD, MDD is the only logical choice.

hungrybox  excellent answer, thank you

What threw me off in this question is the phrase "cells with little cytoplasm that are twice the size of lymphocytes." I though "small cell carcinoma" cannot be that big.

nala_ula  Omg literally the same thought process I had, that phrase through me off!

Can someone please explain why the answer to this is injury to the posterior cord rather than the radial nerve?

pipter  because raising the arm above the shoulder suggests abduction which would mean the axillary nerve is also involved. the lesion would be more proximal. +3  
kchakhabar  I thought "up to the shoulder" is done by deltoid muscle (aka axillary nerve) and above is done by trapezius. +3  
forerofore  as far as i can find, abduction ranges of motion, per first aid are: 0-15° = supraspinatus 15-90° = Deltoid 90° = trapezius 100° (over the head) = serratus anterior in this question, they are directly telling you its not the serratus (long thoracic), because no option compromises it. Also, trapezius is innervated by cranial nerve XI, which is not a part of the brachial plexus, so, even though its worded weirdly, you can assume they are talking about deltoid disfunction. so deltoid disfunction (axillary) + radial disfunction = posterior cord +

Scabies likes to burrow in the areas between the fingers and toes (FA 2019 161) and causes itching. Could also potentially be lice (groin involvement), but treatment for either overlaps -- gotta use permethrin.

kchakhabar  If only one person is there to see the doctor, why would the doctor prescribe medicine even for his family members who are not there? +  
mcl  Unfortunately, both of these are pretty contagious conditions. FA mentions that scabies spreads via skin to skin contact, and goes on to mention that you're supposed to treat close contacts. I think in this scenario it's ok to give permethrin to the family members who are not present but affected (it's also non-prescription in some cases, I believe.) Slightly related note, similar to why you would treat the sexual partner of someone with chlamydia/gonorrhea, or close contacts of someone with n. meningitides infection. +3
