Nurses may find themselves in various situations where usual equipment is not available and manual calculation skills are needed, such as in disasters. Nurses require continuing education regarding dosage calculation skills to build confidence and ensure effective and safe patient care.
Learning Outcome: After completing this learning activity, the learner will be able to describe a userfriendly problem-solving approach for nurses to calculate drug and infusion rates manually during disasters.
Learning Engagement Activity: Identify a calculation problem from your practice; then go through the steps outlined by Polya's Problem-Solving Approach listed in Table 1.
Contact hours available until 8/31/2020. Requirements for Successful Completion: Complete the learning activity in its entirety and complete the online CNE evaluation.

Figure 5 Weight-Based Dosage calculation is incorrect. If the patient is to receive 360 mg of ampicillin and the suspension on hand is 250mg/ml, the patient should receive 1.44ml not 7.2ml. It's ironic that the purpose of the article is to provide a problem solving approach to drug calculation and the provided example is incorrect.

Some of the math in the article wasn't correct.

I agree the math in the article on the weight-based dosing problem is not correct.

Needs to have more rationale. Also, Figure 5 is incorrect.

Figure 5 is wrong. The conversion chart should say 1kg=2.2lbs, so the first answer is almost triple what the actual dose should be (164, and then divided further by 4 for individual doses).

This has a ton of value

I believe that adding refresher and competencies for skills we should have but do not use often are important. Its an added layer of a safety net that we could possibly encounter.

more education and competency refresher courses must be given to nurse to refresh themselves.

The 125 mg of Amoxicillin elixir from a bottle containing 500 mg/10 ml is 2.5 ml, not 0.6 ml.

I agree the calculation in the article on ampicillin is not correct !

In reminding us to practice so that we remain comfortable with such calculations, the article has value. However, it appears that thorough proofreading was not performed. Calculations are not uniformly correct, and the conversion factor of 2.2kg=1lb in the main text is reversed. Unless another nurse were checking independently, I might not want to have this author figure out dosages for me as a patient in case of a disaster.
