Heat, a New Hire, and a Supervisor Who Says 'Push Through'
It is the first week of August in a southern US state. A 22-year-old man starts work on a roofing crew. Daytime heat index reaches 105°F (40.6°C). He has no prior outdoor work experience, is on his third day, and has been drinking water but skipped lunch. At 2 p.m. he becomes confused, stops sweating, and collapses on the roof. His skin is hot and dry, his pulse is 130, and he is combative when coworkers try to help. The supervisor says, 'He's just dehydrated, get him in the truck and give him a sports drink.' The crew has no written heat plan and no cool-down schedule.
1. Differentiate the likely diagnosis from heat exhaustion and justify immediate actions.

This is exertional heat stroke until proven otherwise: confusion and combativeness (altered mental status) plus collapse in a hot environment are the defining features, and the absence of sweating is not required (classic heat stroke is anhidrotic, but exertional heat stroke often presents with sweating). Heat exhaustion, by contrast, involves weakness, dizziness, headache, nausea, and tachycardia with normal mental status. The supervisor's plan - transport in a hot truck and oral fluids - is dangerous: oral fluids are unsafe in a confused patient (aspiration risk), and delay in cooling increases mortality. Immediate actions: call emergency services, move him to shade, remove clothing, and begin active cooling immediately (cold-water immersion is the standard; if unavailable, ice packs to neck, axillae, and groin with fanning and misting), monitor airway and vital signs, and do not give oral fluids until mental status is normal. The judgment point is that altered mental status converts a 'heat' problem into a life-threatening emergency, and cooling starts before transport, not after.
2. Identify the program failures and the prevention steps the employer should have had in place for a new worker.

Failures: no written heat illness prevention plan, no acclimatization schedule for a new hire (new and returning workers need a graded increase in workload over 1-2 weeks), no cool-down/rest schedule, no water or shade provision on the roof, no buddy system or symptom monitoring, and a supervisor who minimized symptoms. Prevention: (1) written plan with a responsible person; (2) acclimatization - start new workers at reduced workload and increase over 7-14 days, with closer supervision in the first week; (3) water and shade/rest breaks at defined intervals scaled to heat index; (4) training for workers and supervisors on recognizing heat illness and the rule that altered mental status = call 911; (5) a buddy system and a 'stop work' authority; (6) emergency response plan with cooling supplies on site. The judgment point is that acclimatization and supervisor behavior are the modifiable determinants, and the exam wants you to name the program elements, not just 'drink water.'
