A
Feedback:
A loading dose (larger than the usual continuing dose) may be given as the first dose of a newly prescribed medication, to establish a minimal blood level. The minimal dose is the smallest amount of drug necessary to achieve a therapeutic effect. A maximal dose is the largest amount that can be given safely without causing an adverse reaction or toxic effect. A blood sample may be obtained to determine the client's blood level of a drug. This helps establish the therapeutic dose for that client.
