Dosage calculation for nursing students explained with drawings and worked examples: conversions, the formula method, ratio and proportion, dimensional analysis, tablets, liquids, weight-based examples and flow rates, with practice problems solved step by step. Generic practice examples, not prescriptions.

The common laboratory tests explained with drawings for nursing students: the complete blood count, electrolytes, kidney tests, glucose and A1C, clotting tests and urinalysis, what each one measures and what to report. Reference ranges vary by laboratory: always use your facility's values.

Step-by-step checklists of basic nursing skills to practice for the lab and clinicals: hand hygiene, PPE, vital signs, bed making, bed bath, positioning, transfers, feeding, intake and output, catheter care, a simple dressing change and oral medications. Always follow your program's and facility's procedure.
