Lewis University CONHP Soph II Math Module Sophomore 2 Guidelines Student must show work for all calculations. The three systems utilized by health care professionals are the metric, apothecary, and household measurements. It is necessary to MEMORIZE each system and to convert form one system to another. All prescriptions are written within the metric system and all US drug labels provide metric measurements. Each answer must be labeled correctly and reflect the correct units and time frames (e.g., tablets, capsule, units, mL, gtt/min, mL/hr, mg /day, etc.) or it will be counted wrong. Tablets are assumed scored, unless otherwise stated. Maintenance and replacement IV fluids and IV additives given on pump (mL /hr) are rounded to the nearest whole number. For IV fluids given by gravity drip (gtt/min) the drip rate must be rounded to the nearest whole drop / whole number. For adults, weights are rounded to the nearest tenth. When reconstituting a powered medication, choose the concentration or dose strength that comes closest to the dose that has been ordered. For injectable medications, amounts <1.0 mL are rounded to the hundredths place and amounts >1.0 mL are rounded to the tenths place.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
