Final answer:
To determine the glucagon dosage for an 8-year-old patient, one would typically administer 1.0 mg assuming the child's weight is more than 20 kg, which is the standard emergency dose for hypoglycemia in children. Without the child's weight, option B) 1.0 mg would generally be correct for most 8-year-olds.
Step-by-step explanation:
The question asks how much glucagon should be given to an 8-year-old patient. In medical practice, glucagon administration is guided by the patient's body weight and the purpose of the drug usage. According to the glucagon tolerance test protocol, the intravenous dose of glucagon should be 30 µg/kg body weight. To determine the correct dosage for an 8-year-old, we need to know the child's weight. However, if we are discussing standard emergency hypoglycemia treatment rather than a glucagon tolerance test, different dosages apply.
If we assume an average weight for an 8-year-old, we will use the general pediatric dosing for glucagon, which is typically 1.0 mg for a child weighing more than 20 kg. If the child weighs less, the dosage would be 0.5 mg. Without weight information, the best answer with the options provided would be B) 1.0 mg, as most 8-year-old children would weigh enough for this dose. It's important always to follow specific medical guidelines and dosing protocols provided for each individual situation.
