Charcots triad (fever, jaundice, RUQ pain) is indicative of which condition?
💡 EXPLANATION:
Charcots triad points to Acute Cholangitis, which is an infection of the bile duct, often due to obstruction. Remember the triad as F-J-P: Fever, Jaundice, Pain (RUQ).

What is the primary mechanism of action of Diltiazem?
💡 EXPLANATION:
Diltiazem is a non-dihydropyridine calcium channel blocker. It works by blocking L-type calcium channels in vascular smooth muscle and the heart, leading to vasodilation and a reduction in heart rate.

A 60M with BPH has N/V. Labs: Na 145, BUN 45, Cr 2.0, Urine Na 10, Urine Cr 80. These lab values are most consistent with which diagnosis?
💡 EXPLANATION:
Early postrenal obstruction increases tubular pressure, enhancing sodium and urea reabsorption, which mimics a prerenal picture (BUN:Cr >20, FeNa <1%). However, the history of BPH strongly suggests postrenal AKI.

The underlying pathophysiology of Osteoarthritis involves:
💡 EXPLANATION:
Osteoarthritis is a degenerative wear-and-tear disease. Its core mechanism is the breakdown of articular cartilage by enzymes like matrix metalloproteinases (MMPs), leading to pain and reduced joint function.

What is the recommended first-line treatment for a bloodstream infection caused by Vancomycin-Resistant Enterococcus (VRE)?
💡 EXPLANATION:
Linezolid is the recommended first-line treatment for most serious VRE infections, including bacteremia. Daptomycin is an alternative. Vancomycin is ineffective due to resistance.

A child with known recurrent SVT is now unresponsive, hypotensive, with cold extremities. These new findings are most likely due to which complication?
💡 EXPLANATION:
SVT at a high rate impairs ventricular filling, causing a critical drop in cardiac output. This leads to hypotension and systemic hypoperfusion (shock), causing unresponsiveness and cold extremities.

Recall the 45M evaluated for brain death. The organ procurement organization is consulted. Which of the following is an absolute contraindication to him being a cardiac donor?
💡 EXPLANATION:
Severe and irreversible cardiac dysfunction (e.g., EF <30%) is an absolute contraindication for heart donation. The profound catecholamine surge during brain death can cause neurogenic stunned myocardium, requiring echocardiogram evaluation.

A 67M post-stroke has a droopy left eyelid, a constricted left pupil, and loss of pain/temperature sensation on his left face and right body. What is the most likely diagnosis?
💡 EXPLANATION:
This classic presentation is known as Lateral Medullary (Wallenberg) Syndrome. The combination of ipsilateral Horner's syndrome (ptosis, miosis) and facial sensory loss with contralateral body sensory loss points to a lesion in the lateral medulla. Medial Medullary Syndrome presents with contralateral hemiparesis and ipsilateral tongue deviation. Weber's Syndrome is a midbrain stroke causing an ipsilateral CN III palsy and contralateral weakness. Locked-in Syndrome results from a pontine stroke, causing quadriplegia and mutism.
