### Solution Guide for Module 4 Dosage Range and “Is it safe?” Problems

Some problems in the text and in Worksheet 32 are dosage range or “Is it safe?” problems. Click this link to receive more information on dosage range/is-it-safe problems.

These problems require that two sets of calculations be made, one for the LOW LIMIT of the dosage range and one for the HIGH LIMIT. The ordered dose is then compared to these limits to see if it is either within limits and, therefore, SAFE or outside the limits and, therefore, potentially UNSAFE. Note that both the limits and the ordered amount must be in the same units.

### Erratum, Module 4 Problem from the Textbook

The text’s incorrect answer to problem 3, page 216 is 9.7 mL/dose. The correct answer is 4.8 mL/dose.

The previous edition of the text had this same question, but in that edition the medication label displayed a concentration of 125 mg/5 mL; since the new label’s concentration is 250 mg/5 mL, the required number of mL is half that stated in the answer section.
