How much activated charcoal should you administer to a 42-year-old patient weighing 154 pounds?

Activated charcoal is commonly used in emergency medicine for the treatment of certain types of poisoning or overdose. The general guideline for administering activated charcoal in adults is to use a dose of 1 gram per kilogram of body weight.

To determine the correct dosage for a patient weighing 154 pounds, you first need to convert that weight into kilograms. There are approximately 2.2 pounds in a kilogram, so dividing 154 pounds by 2.2 gives you about 70 kilograms. Using the standard dosage of 1 gram per kilogram, you would multiply 70 kilograms by 1 gram, resulting in a total of 70 grams of activated charcoal.

This dose is effective for the gastrointestinal absorption of various toxins, and it is important not to exceed recommended doses, as this could lead to complications. Other options provided significantly exceed the appropriate dosage, making them unsuitable for safe administration. Thus, administering 70 grams is the correct choice for a patient of this weight.
