Miscalculations can lead to underdosing, which may fail to alleviate the patient\u2019s symptoms, or overdosing, which could result in adverse effects or toxicity. In this case, understanding the concentration of the diphenhydramine formulation allowed for accurate volume calculation, ensuring the patient receives the correct amount of medication as ordered. This approach is critical in nursing practice, where precise dosages can significantly impact patient outcomes. Always double-check calculations and consult with pharmacy resources when in doubt about medication administration.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Order: Diphenhydramine 25mg Q4H Available: Diphenhydramine 12.5mg\/5mL How much will you administer?
