CNA practice test (nurse aide knowledge exam practice): cram pack

Nursing assistant (CNA) knowledge

Method

1. Check whether the resident is in danger right now (not breathing, choking, a fall, chest pain, stroke signs); if so, keep them safe and get the nurse at once.
2. Ask whether the task is within the nursing assistant’s scope and training; if not, decline politely and tell the nurse.
3. Respect the resident’s rights: privacy, choice, refusal of care, dignity and freedom from abuse and unneeded restraints.
4. Apply the basic rules: hand hygiene, body mechanics, bed low and call light within reach, weak side first when dressing.
5. Observe and report: compare with the resident’s usual state and report changes promptly and objectively.

Nursing math & unit conversions

Metric steps

1 kg = 1000 g, 1 g = 1000 mg, 1 mg = 1000 mcg, 1 L = 1000 mL

Weight and length

1 kg = 2.2 lb, 1 lb = 16 oz, 1 in = 2.54 cm, 1 ft = 12 in

Household measures

1 tsp = 5 mL, 1 tbsp = 15 mL, 1 fl oz = 30 mL, 1 cup = 8 fl oz = 240 mL

Temperature

°C = (°F − 32)·5/9, °F = °C·9/5 + 32

24-hour clock

PM hours 1–11: add 12; 12 AM = 00:xx; 12 PM = 12:xx

Dose rate

mcg/min × 60/1000 = mg/h

Laboratory factors

glucose 1 mmol/L = 18 mg/dL; creatinine 1 mg/dL = 88.4 µmol/L; Hb 1 g/dL = 10 g/L

Method

1. Write the given quantity with its unit and the unit you want.
2. Pick the equivalent: 1000 between kg, g, mg and mcg or L and mL; 1 kg = 2.2 lb; 1 tsp = 5 mL, 1 tbsp = 15 mL, 1 fl oz = 30 mL, 1 cup = 240 mL.
3. Write it as a fraction so that the unwanted unit cancels; for a rate, use one fraction per unit that changes.
4. Check the direction: a smaller unit gives a bigger number.
5. Round only the final answer, to the precision the question names.
