Final answer:
An accurate loading dose for heparin cannot be determined without the specific protocol details. Loading doses commonly range from 3,000 to 5,000 units, with some weight-based protocols recommending 80 units/kg leading to a possible 6,400 units for an 80 kg individual, which would be rounded to 6,000 units.
Step-by-step explanation:
Without specific details of the heparin protocol, it's not possible to provide an accurate loading dose required for the client who weighs 80 kg. Heparin dosing can vary depending on the indication for use (e.g., treatment or prophylaxis of thrombosis), the presence of any underlying conditions, and the specific protocol being followed by the healthcare institution. Common initial loading doses for heparin can range from 3,000 to 5,000 units, administered intravenously. However, it is not uncommon for some protocols to use weight-based dosing, such as 80 units/kg for an 80 kg individual, which would result in an initial loading dose of 6,400 units, typically rounded to the nearest 1,000 units due to practicalities of administration. According to this example, the nearest 100-unit increment would be 6,000 units. However, proper dosing should be confirmed with the specific protocol or by consulting a healthcare professional.
