Six organisms. Six classic Step 1 illness scripts. 🍄🦠

Before swiping, try to identify each diagnosis from the host → presentation → image clue.

Save this rapid review for your next NBME. 📌

A patient with advanced HIV develops a subacute headache and meningismus. Lumbar puncture shows markedly increased opening pressure, and India ink is positive. 🧠

Diagnosis: Cryptococcus neoformans

Save this HIV meningitis pattern. 📌

A patient in diabetic ketoacidosis develops severe facial pain, sinusitis, and a black nasal eschar. Microscopy shows broad, ribbon-like hyphae. 🍄

Diagnosis: Mucor or Rhizopus

Remember the DKA association. 📌

A patient with HIV and a CD4 count below 200 develops fever, progressive dyspnea, and a dry cough. Imaging shows diffuse ground-glass infiltrates. 🫁

Diagnosis: Pneumocystis jirovecii pneumonia

Save the CD4 threshold. 📌

A patient with AIDS and a CD4 count below 100 presents with headache and seizures. Brain imaging shows multiple ring-enhancing lesions. 🧠

Diagnosis: Toxoplasma gondii encephalitis

Lock in the imaging pattern. 📌

A traveler develops recurrent fevers and hemolytic anemia. Peripheral smear shows delicate ring forms and crescent-shaped gametocytes. 🦟

Diagnosis: Plasmodium falciparum malaria

Remember the smear findings. 📌

After drinking untreated stream water, a camper develops bloating and foul-smelling, greasy diarrhea. The organism is pear-shaped and associated with IgA deficiency. 💧

Diagnosis: Giardia duodenalis

Save the exposure pattern. 📌

Recognizing the illness script is only step one.

Next comes virulence factors. 💊

‘USMLE Pharm’

…and I’ll send you my FREE study guide & a link to sign up for my LIVE review session next weekend! 🔥

‼️ Note: Pharm & Micro ~20% of the exam & are the easiest points on your CBSE/USMLE! 🦠🧫

Roses are red, violets are blue, rosettes are a clue…and your next NBME knows it too 🙃 🌹

USMLE prep is not just a content or test taking strategy grind. 🌄

It’s a series of mindsets you have to embrace. 🥼

You have to accept that progress will not always look linear. Your practice scores may rise, fall, and plateau—even when you are doing the right things. 🫶🏼

You have to become willing to leave the comfort of familiar resources and spend more time where your weaknesses are exposed.

You have to remember that the exam often feels largest before you begin.

Every question block, review session, and focused study day makes it a little more manageable.

You also have to learn when to pause. Rest is not something you earn only after burning yourself out. It is part of preparing well. 🧘🏾‍♂️

Some days will feel productive. Other days will feel messy. Both can still be part of meaningful progress. 🙌🏽🔥

Keep showing up. Not perfectly...just consistently. 🩺


We imagine progress as a straight climb.

In reality, it may feel confusing, uneven, and anything but linear. 🧗‍♀️

Your best performance will not appear every day.

A difficult study day does not erase the work you have already done. ✔️

Your favorite resources may feel comfortable.

Your NBME mistakes reveal where your real growth needs to happen. 📈🫶🏼

It feels heavy because you may be thinking about the future implications.

One study session can help ease the worry of the future.🔮

Focus on the process...

Do not wait until you are completely depleted to rest.

A well-timed break is part of the strategy.

To me, this meant no studying in bed and a hard shutdown time. ⏰

At the end of the day, you're doing this for your future patients. 🥼🩺🩻

You got this! 🙂

Most students memorize a long list of anemias.

The NBME wants you to organize them. 🩸

When you see a low hemoglobin, use this sequence:

1️⃣ Confirm the anemia

Look for fatigue, pallor, exertional dyspnea, tachycardia, or decreased exercise tolerance.

2️⃣ Check the MCV

• Microcytic → iron deficiency, thalassemia, chronic inflammation, sideroblastic anemia
• Normocytic → blood loss, hemolysis, CKD, chronic disease, or marrow suppression
• Macrocytic → vitamin B₁₂/folate deficiency, medications, alcohol, liver disease, or myelodysplasia

3️⃣ Check the reticulocyte response

⬆️ Reticulocytes = the marrow is responding → think blood loss or hemolysis

⬇️ Reticulocytes = inadequate production → think nutrient deficiency, renal disease, inflammation, or bone marrow pathology

tl;dr:

MCV tells you what the red cells look like.

The reticulocyte count tells you what the bone marrow is doing.

Hope this helps in your USMLE preparation 🙂
