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.

3Solutions
1.Nursing assistant (CNA) knowledge
Answer: C · Teach one simple step at a time, praise success and be patient
Why this is the answer
Breaking a task into small steps, demonstrating, repeating and praising progress helps people with intellectual disabilities learn. This builds independence and self-esteem.
Answer
C · Teach one simple step at a time, praise success and be patient
2.Nursing assistant (CNA) knowledge
Answer: B · Cool it with cool water and tell the nurse right away
Why this is the answer
A burn is cooled promptly with cool water, and any clothing that is soaked with the hot drink but not stuck to the skin is removed. The nurse assesses the burn. Butter and ice can worsen the injury.
Answer
B · Cool it with cool water and tell the nurse right away
3.Nursing math & unit conversions
Answer: 14:10
24-hour clock: from 1 PM onwards add 12 to the hour (3:45 PM = 15:45). Midnight to 12:59 AM is 00:00–00:59, and 12:00–12:59 PM stays 12:00–12:59. Going back, subtract 12 from hours 13–23 and add PM; hours 00 become 12 AM. Count time across midnight in two parts: up to 24:00 (00:00), then from 00:00 on.
Convert the hour
2 PM → 2 + 12 = 14
Answer
14:10

14:10
4.Nursing math & unit conversions
Answer: t = 12.5 h
24-hour clock: from 1 PM onwards add 12 to the hour (3:45 PM = 15:45). Midnight to 12:59 AM is 00:00–00:59, and 12:00–12:59 PM stays 12:00–12:59. Going back, subtract 12 from hours 13–23 and add PM; hours 00 become 12 AM. Count time across midnight in two parts: up to 24:00 (00:00), then from 00:00 on.
Before midnight
18:10 → 24:00 = 350 min
After midnight
00:00 → 06:40 = 400 min
Total
350 + 400 = 750 min
t = 750/60 = 12.5 h
Answer
t = 12.5 h
