Free NACC Practice Questions on Nutrition & Hydration (Ontario PSW Exam Prep)

If you are studying for the NACC Personal Support Worker (PSW) exam in Ontario, nutrition and hydration is a core, heavily tested topic — helping clients eat and drink safely is one of the most frequent parts of the PSW role, and one of the riskiest when it goes wrong. Almost every nutrition question is really a question about safety, your scope of practice, and the client's dignity. This free practice set gives you real NACC-style questions on dehydration, intake and output, safe feeding positions, therapeutic diets, malnutrition, and mealtime dignity, each with a clear answer. Work through them, then keep going at pswleap.com/learn.

What does a PSW do for nutrition and hydration, and why does the NACC exam test it?

A PSW assists, encourages, observes, and reports when it comes to food and fluids — they do not prescribe diets or make clinical decisions. For a Personal Support Worker in Ontario, helping clients eat and drink happens at almost every visit, and it is where small problems become serious fast: an older adult who quietly stops drinking can be confused and dehydrated within days, and a client fed in the wrong position can aspirate.

The exam tests it heavily because it ties together several core competencies at once — observation and reporting, safe positioning, infection control, person-centred care, and your scope of practice. You are not expected to order a diet, change a fluid restriction, or diagnose malnutrition. You are expected to serve the prescribed diet exactly, position the client safely, encourage food and fluids, promote independence, and report changes in appetite, weight, and intake. On the exam, the best answer is almost always the one that keeps the client safe, nourished, hydrated, and in control of their own meals.

Quick facts to memorize: Sit the client upright at 90° to eat and stay up 30 minutes after. Dehydration signs = dark urine, dry mouth, confusion, dizziness, low BP. Most adults need ~1,500–2,000 mL of fluid a day (unless on a restriction). 1 mL of fluid = 1 g; all liquids and foods that melt (ice chips, gelatin, ice cream, soup) count as fluid intake. A PSW never changes a prescribed diet or fluid order — follow the care plan and report. NPO = nothing by mouth.

Free NACC-style practice questions: nutrition & hydration

Each question below mirrors the scenario-based, single-best-answer style of the NACC PSW exam. Try to answer before you read the explanation.

Q1. Why does the NACC PSW exam put so much weight on nutrition and hydration?

Answer: Because feeding clients safely is frequent, high-risk, and tests safety, scope, and observation all at once. Poor intake leads to dehydration, malnutrition, weight loss, and confusion, and unsafe feeding causes choking and aspiration. The exam wants the answer that keeps the client safe and well-nourished while following the care plan — not the fastest option for the worker, and never an answer where the PSW changes a diet or acts outside their training.

Q2. A client's family asks you to add salt to a client who is on a low-sodium diet. What should the PSW do?

Answer: Do not change the diet — explain you must follow the care plan, and report the request to the nurse. A PSW must never add to, change, or withhold a prescribed diet or fluid order. Therapeutic diets like low-sodium are ordered for medical reasons, and overriding them can cause real harm. Politely explain that the diet is part of the client's care plan, serve the meal as ordered, and pass the family's request to the nurse, who can involve the dietitian if appropriate.

Q3. What early signs tell a PSW that a client may be dehydrated?

Answer: Dark, strong-smelling urine, a dry mouth, new confusion, dizziness, and low blood pressure. Older adults lose their sense of thirst, so dehydration often shows up as confusion or a fall before the client ever says they are thirsty. Watch also for sunken eyes, a fast pulse, and skin that 'tents' when pinched. If the client is allowed fluids, encourage small drinks; either way, report the changes to the nurse the same shift, because dehydration can quickly cause infections and hospital admission.

Q4. A client says they "just aren't thirsty" and barely drinks. How should the PSW encourage fluids?

Answer: Offer small amounts of preferred drinks often, and keep a filled cup within reach all day. Frequent small sips work better than one large glass, and people drink more of what they like — water, juice, milk, tea, soup, or ice chips all count. Most adults need about 1,500–2,000 mL a day, but always check the care plan first: a client with heart or kidney disease may be on a fluid restriction and must not be pushed to drink more.

Q5. You are keeping an intake and output (I&O) record. Which of these counts as fluid intake?

Answer: All liquids and foods that are liquid at room temperature — including soup, gelatin, ice cream, and ice chips. Fluid intake is not just what the client drinks from a glass; anything that melts or pours counts. Record everything taken in and everything that comes out (urine, vomit, diarrhea, drainage) in millilitres on the I&O chart. Remember that 1 mL equals 1 g. Accurate I&O is how the team catches dehydration and fluid overload early, so measure and record it precisely instead of estimating.

Q6. In what position should a PSW place a client to eat and drink?

Answer: Sitting fully upright at 90 degrees, and staying upright for at least 30 minutes after the meal. Sitting upright lets gravity carry food and fluid safely down the esophagus instead of into the airway, lowering the risk of choking and aspiration. Never feed a client who is lying flat, slumped, drowsy, or tipped back. "Upright to eat, stay up after" is one of the most reliable safety answers on the NACC exam.

Q7. While you help feed a client, they begin to cough and their voice sounds wet and gurgly. What should the PSW do?

Answer: Stop feeding immediately, keep the client upright, and report it — these are signs of swallowing trouble. Coughing, a wet or gurgly voice, or holding food in the mouth can signal that food or fluid is going toward the airway (aspiration). Do not keep feeding to "finish the meal." Stay with the client, keep them sitting up, and report to the nurse right away; the client may need a swallowing assessment or a texture-modified diet.

Q8. When assisting a client who eats slowly, what is the right approach?

Answer: Sit at eye level, offer small bites at the client's pace, and alternate food with sips of fluid — never rush. Check that the mouth is empty before offering the next bite, keep the chin slightly down rather than tipped up, and follow the order of foods the client prefers. Rushing a client, talking them into hurrying, or stacking spoonfuls increases the risk of choking and strips away dignity. Patient, unhurried feeding is exactly what the exam rewards.

Q9. Over two weeks you notice a client is eating less than half of each meal and their clothes are looser. What should the PSW do?

Answer: Report the reduced intake and weight loss to the nurse, and document what the client actually ate. Eating less than half of meals, unplanned weight loss, and loose-fitting clothes or dentures are early signs of malnutrition, which raises the risk of falls, infection, and pressure injuries. The PSW observes and reports — not diagnoses. Record intake objectively (for example, "ate about 25% of lunch, refused supper") so the care team can act early.

Q10. A client wants to eat their evening meal with their hands and chooses to skip the vegetables. The food is within their prescribed diet. What should the PSW do?

Answer: Respect the client's choices and independence — offer finger foods and let them decline the vegetables. As long as the meal stays within the prescribed diet, the client has the right to choose what, when, and how they eat. Promoting independence and honouring preferences — including cultural and religious ones — protects dignity and is central to person-centred care. On the NACC exam, forcing food, taking over, or removing choices is almost always the wrong answer; supporting the client to eat their own way is almost always right.

When a scenario stumps you, fall back on the backbone: follow the care plan → position safely → assist without rushing → observe and report. The answer that keeps the client safe, nourished, and in control of their own meal is rarely wrong; the answer that rushes, force-feeds, or changes a diet to "help" usually is.

Common nutrition & hydration mistakes to avoid on the NACC exam

• Feeding a client who is lying down or slumped instead of sitting them upright at 90°.
• Changing, adding to, or withholding a prescribed diet — for example, giving thin fluids to a client on thickened fluids, or salt to a client on a low-sodium diet.
• Pushing fluids on a client who is on a fluid restriction instead of checking the care plan first.
• Rushing a client or stacking the next bite before the mouth is empty.
• Ignoring a cough, wet voice, or pocketed food during meals — these are aspiration warning signs to report.
• Estimating I&O instead of measuring, or forgetting that soup, gelatin, and ice chips count as fluid.
• Doing everything for a client who could feed themselves with finger foods or adaptive utensils.
