Final answer:
The appropriate dose for a fluid bolus in a patient with cardiac compromise varies depending on the severity of the condition, but a common dosage is 20 mL per kg of body weight.
Step-by-step explanation:
The appropriate dose for a fluid bolus in a patient with cardiac compromise depends on the severity of the compromise and the specific circumstances. In general, a fluid bolus is given to increase the fluid volume in the patient's circulation and improve cardiac output. The volume of the fluid bolus can vary, but a commonly used dosage is 20 mL per kg of body weight. For example, a 70-kg individual would receive a 1400 mL fluid bolus.
