Session Progress
This Certified Nursing Assistant Nutrition, Hydration, Elimination & Comfort practice set has 66 practice questions based on the official exam materials, each with an instant explanation.
Sample questions
Three questions from the Nutrition, Hydration, Elimination & Comfort bank with the correct answer and an explanation. The practice quiz above draws 30 questions at random from the same bank.
In what position should the nurse aide place a resident for eating a meal?
- Sitting upright at about a 90-degree angle — Correct answer
- Lying flat on the back
- Lying on the side
- Reclined with the head lower than the feet
Explanation: The resident should be seated upright at about 90 degrees (Fowler's position if in bed) so gravity helps food and liquid go down the esophagus, not the airway. This prevents aspiration (误吸/aspiración). (Source: Activities of Daily Living — Nutrition/Hydration)

After a resident finishes a meal in bed, how long should the head of the bed stay elevated?
- About 30 minutes after the meal — Correct answer
- It can be lowered flat right away
- Only a few seconds
- A full 4 hours
Explanation: Keep the resident sitting upright for about 30 minutes after eating so food stays in the stomach and does not flow back up, which lowers the risk of aspiration (误吸/aspiración). (Source: Activities of Daily Living — Nutrition/Hydration)

Before serving a meal tray, what must the nurse aide check first?
- That the tray and diet card match the right resident and the ordered diet — Correct answer
- That the food is the aide's favorite meal
- Nothing — just hand over any available tray
- Only that the tray is warm
Explanation: Always verify the right resident gets the right tray by checking the name/identification and the diet card against the diet order. Serving the wrong diet can cause choking, an allergic reaction, or harm. (Source: Activities of Daily Living — Nutrition/Hydration)
