A 58-year-old man presents to the emergency department after spending several hours gardening and mowing the lawn in hot weather. He reports experiencing muscle cramps, dizziness, and excessive sweating before arrival. He has no significant past medical history and is generally in good health. On examination, his skin is warm and flushed, his heart rate is elevated, and he appears mildly confused. Laboratory tests reveal: serum osmolality: Elevated and serum sodium: Borderline high. What is the likely explanation for this finding?

A 28-year-old healthcare worker undergoes routine tuberculosis (TB) screening and has a positive tuberculin skin test (TST) but denies cough, fever, weight loss, or night sweats. A chest X-ray is normal, and sputum cultures are negative for Mycobacterium tuberculosis. The patient is concerned about transmitting TB to others and asks if they are contagious. The healthcare provider informed the patient he likely has latent TB and can transmit the infection.

An x-ray tube emits 1014 photons per second. The x-ray is assumed to contain only 50-keV photons and irradiates a 0.2-mm-thick tissue sample for 0.2 second. The HVL of the sample is 0.8 cm, and the energy absorption coefficient of the sample is 0.1 cm−1 for 50-keV photons.

An X-ray containing 6,336 photons strikes through 6 HVL’s of a material. How many photons are left?
