Nursing assistant (CNA) knowledge
Method
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.
Ask whether the task is within the nursing assistant’s scope and training; if not, decline politely and tell the nurse.
Respect the resident’s rights: privacy, choice, refusal of care, dignity and freedom from abuse and unneeded restraints.
Apply the basic rules: hand hygiene, body mechanics, bed low and call light within reach, weak side first when dressing.
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
Write the given quantity with its unit and the unit you want.
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.
Write it as a fraction so that the unwanted unit cancels; for a rate, use one fraction per unit that changes.
Check the direction: a smaller unit gives a bigger number.
Round only the final answer, to the precision the question names.
2Practice problems
1.Nursing assistant (CNA) knowledgeMedium

DGo to work and tell no one
3.Nursing math & unit conversionsMedium
Practice exercise (made-up values, not clinical guidance). A newborn weighs 9 lb 1 oz. Using 1 lb = 16 oz and 1 kg = 2.2 lb, find the weight m in kilograms. Round to two decimal places.
9 lb 1 oz1 lb = 16 oz1 kg = 2.2 lb
m = kg
4.Nursing math & unit conversionsHard
Practice exercise (made-up values, not clinical guidance). During a shift a patient takes ½ cup of tea, ½ tbsp of liquid supplement, 3 tsp of cough syrup, 6 fl oz of juice. Using the equivalents given, find the total oral intake V in mL.
1 cup = 8 fl oz = 240 mL1 tbsp = 15 mL1 tsp = 5 mL1 fl oz = 30 mL
V = mL
3Solutions
1.Nursing assistant (CNA) knowledge
Answer: C · Help pack, check belongings against the list and help the resident out safely
Why this is the answer
For discharge, the nursing assistant helps collect and check belongings and assists the resident out safely, often by wheelchair, following policy. The nurse gives medical instructions.
Answer
C · Help pack, check belongings against the list and help the resident out safely
2.Nursing assistant (CNA) knowledge
Answer: C · Call the supervisor before the shift, following facility policy
Why this is the answer
Staff who are ill can spread infection to residents, who are often frail. The nursing assistant follows the facility's illness policy and tells the supervisor before the shift so care can be covered.
Answer
C · Call the supervisor before the shift, following facility policy
3.Nursing math & unit conversions
Answer: m = 4.12 kg
Household measures and weight: nursing exams use rounded equivalents: 1 teaspoon (tsp) = 5 mL, 1 tablespoon (tbsp) = 15 mL = 3 tsp, 1 fluid ounce (fl oz) = 30 mL = 2 tbsp, and 1 cup = 8 fl oz = 240 mL. For weight, 1 kg = 2.2 lb and 1 lb = 16 oz; for length, 1 inch = 2.54 cm. Set the conversion up so that the unit you do not want cancels out.
Ounces to pounds
1 oz/16 = 0.0625 lb
9 + 0.0625 = 9.063 lb
Pounds to kilograms
m = 9.063/2.2 = 4.119 ≈ 4.12 kg
Answer
m = 4.12 kg
4.Nursing math & unit conversions
Answer: V = 322.5 mL
Household measures and weight: nursing exams use rounded equivalents: 1 teaspoon (tsp) = 5 mL, 1 tablespoon (tbsp) = 15 mL = 3 tsp, 1 fluid ounce (fl oz) = 30 mL = 2 tbsp, and 1 cup = 8 fl oz = 240 mL. For weight, 1 kg = 2.2 lb and 1 lb = 16 oz; for length, 1 inch = 2.54 cm. Set the conversion up so that the unit you do not want cancels out.
Each item in mL
½ cup = 0.5·240 = 120 mL
½ tbsp = 0.5·15 = 7.5 mL
3 tsp = 3·5 = 15 mL
6 fl oz = 6·30 = 180 mL
Add
V = 120 + 7.5 + 15 + 180 = 322.5 mL
Answer
V = 322.5 mL
