Final answer:
The treatment plan for salbutamol under the Bronchoconstriction Medical Directive via NEB for a patient weighing under 25kg involves calculating the dosage based on the patient's weight and administering it via a nebulizer.
Step-by-step explanation:
Salbutamol is a medication commonly used to treat bronchoconstriction, which is a narrowing of the airways in the lungs. When administered via a nebulizer to a patient who weighs less than 25kg, the treatment plan may involve giving a specific dose of salbutamol. The dosage will depend on the patient's weight and will typically be calculated as a certain number of micrograms per kilogram of body weight.
