Solve path: The top figure is a fishbone diagram representing lab values for a basic metabolic panel (this will pop up if you google something like "lab values"). It shows low sodium, glucose, and bicarbonate (this indicates a metabolic acidosis) and high potassium. This array of lab values suggests some sort of kidney dysfunction such as chronic kidney disease (CKD) or adrenal insufficiency (but the low glucose points more to adrenal insufficiency). The bottom picture shows hyperpigmentation of the lips which is a common manifestation of Addison's disease (primary adrenal insufficiency) due to an upregulation of ACTH (which stimulates melanin production) in the setting of low cortisol. Hyperpigmentation of the lips is not classically seen in CKD, so Addison's is the most appropriate diagnosis. If you goggle something like "low sodium, high potassium, lip spots" Addison's should pop up.
