Question 1

A petroleum worker exposed to extreme heat on a drilling rig loses electrolytes through sweat. Which electrolyte is most critical to replace to prevent muscle cramps?

Accepted Answer

Sodium

Answer

Sodium is the primary electrolyte lost in sweat and its depletion causes hyponatremia and muscle cramping in heat-exposed workers.

Question 2

During a 12-hour shift on an oil rig in summer, how much water should a worker typically consume per hour during moderate physical activity in the heat?

Accepted Answer

1 cup (8 oz)

Answer

OSHA and NIOSH recommend approximately 1 cup (8 oz) of water every 15–20 minutes, totaling about 1 cup per 15–20 minutes during heat exposure.

Question 3

Which type of beverage is LEAST effective for rehydrating a petroleum worker after heavy physical exertion in the field?

Accepted Answer

Caffeinated energy drinks

Answer

Caffeinated energy drinks act as diuretics and can increase fluid loss, making them counterproductive for rehydration after heavy exertion.

Question 4

A field worker notices urine that is dark amber in color. This most likely indicates:

Accepted Answer

Dehydration

Answer

Dark amber urine is a reliable field indicator of dehydration; pale yellow urine indicates adequate hydration.

Question 5

Which macronutrient provides the quickest available energy source for petroleum workers engaged in burst-activity tasks like lifting and hauling equipment?

Accepted Answer

Carbohydrates

Answer

Carbohydrates are broken down into glucose, which is the body's fastest and most readily available fuel for high-intensity physical tasks.
