Stomach Flu or Food Poisoning Quiz
Questions: 16 · 10 minutes
1. Why are antibiotics not a routine treatment for every case of vomiting and diarrhea?
Antibiotics treat dehydration rather than infection.
Antibiotics work only when symptoms begin within two hours of eating.
Antibiotics prevent all infected people from spreading illness immediately.
Many cases are viral or self-limited, and antibiotics may be unnecessary or inappropriate for some infections.
2. For mild vomiting and diarrhea, what is generally the most useful hydration approach?
Drink a large amount of plain water all at once.
Use only highly caffeinated drinks to restore energy.
Avoid all liquids until vomiting has been absent for a full day.
Take frequent small sips of an oral rehydration solution or another appropriate fluid.
3. Someone has diarrhea containing visible blood. Which response is most appropriate?
Assume it is a routine stomach virus and ignore it if cramps are mild.
Take the maximum dose of an antidiarrheal before seeking any advice.
Stop drinking fluids so the diarrhea will slow down.
Contact a healthcare professional promptly and avoid self-treating with antidiarrheals unless advised.
4. Which kitchen practice best reduces cross-contamination from raw meat or poultry?
Keep raw items and their utensils separate from ready-to-eat foods, and clean hands and surfaces thoroughly.
Rinse raw poultry in the sink before preparing salad nearby.
Use the same cutting board for raw meat and cooked food if it looks clean.
Judge whether a surface is contaminated only by its smell.
5. Who may need earlier medical guidance when vomiting or diarrhea occurs because dehydration or complications can be more consequential?
Only people who ate at a restaurant.
Only people whose symptoms began at night.
Infants, older adults, pregnant people, and people with weakened immune systems or significant health conditions.
Only people who can identify the exact food they suspect.
6. Several coworkers develop vomiting and cramps a few hours after eating the same catered dish. What does this pattern most strongly suggest?
A contagious stomach virus is ruled out completely.
A shared foodborne source is plausible, although the pattern alone does not prove the cause.
The last person to become ill must have infected everyone else.
The illness cannot be food-related because symptoms appeared on the same day.
7. Can vomiting, diarrhea, cramps, and nausea alone reliably reveal whether someone has stomach flu or food poisoning?
Yes; vomiting always indicates food poisoning.
Yes; diarrhea always indicates stomach flu.
No; the symptoms overlap, so exposure history, timing, testing, and medical assessment may be needed.
No; but the person’s age alone can reliably distinguish them.
8. A food worker has recovered from a vomiting and diarrhea illness suspected to be norovirus. What is the commonly recommended minimum wait after symptoms stop before handling food for others?
Wait at least 48 hours after symptoms stop, while following local workplace or public-health rules.
Wait six hours after the final episode.
Wait until one normal meal has been eaten.
Return as soon as vomiting stops, even if diarrhea continues.
9. Which situation most clearly calls for prompt medical assessment rather than routine home monitoring?
The person has mild nausea but is drinking and urinating normally.
The person cannot keep fluids down and is urinating very little or becoming markedly dizzy.
The person skipped one meal because food seemed unappealing.
The person has one loose stool and otherwise feels normal.
10. After eating home-canned food, someone develops blurred vision, trouble swallowing, and muscle weakness. What is the safest response?
Seek emergency medical help because these can be signs of botulism.
Wait for diarrhea to appear before deciding what to do.
Take an over-the-counter antidiarrheal and sleep.
Drink extra water and reassess after several days.
11. After caring for someone who has been vomiting, which hygiene step is especially important for reducing the spread of norovirus?
Wash hands thoroughly with soap and water, especially after cleanup and before handling food.
Rinse hands briefly with cold water without soap.
Wear the same disposable gloves for cleanup and food preparation.
Rely only on fragrance-free hand lotion after removing gloves.
12. Which cluster is most consistent with significant dehydration?
Increased urination, watery eyes, and greater appetite.
Sneezing, nasal congestion, and an itchy throat.
Mild hunger, normal urination, and brief hiccups.
Very little urine, a dry mouth, and dizziness when standing.
13. What is a key advantage of an oral rehydration solution during fluid loss from vomiting or diarrhea?
It immediately eliminates the infection causing the symptoms.
It provides water and appropriately balanced salts and sugar to support fluid absorption.
It guarantees that medical evaluation will not be needed.
It prevents every further episode of vomiting.
14. At an ordinary indoor temperature, when should perishable leftovers generally be refrigerated?
Only after they have cooled on the counter overnight.
Within about two hours, or sooner in unusually hot conditions.
Within six hours, regardless of room temperature.
Whenever their smell begins to change.
15. One child begins vomiting, and different household members develop similar symptoms over the next two days despite eating different meals. Which interpretation is most reasonable?
The sequence proves that the household water is contaminated.
Different meals rule out any infectious cause.
Person-to-person spread of viral gastroenteritis is plausible, but the pattern does not confirm a diagnosis.
The first child must have had a food allergy.
16. Which statement best distinguishes viral “stomach flu” from food poisoning?
Stomach flu affects only the stomach, while food poisoning affects only the intestines.
Stomach flu is always contagious, while every type of food poisoning is noncontagious.
Stomach flu usually refers to viral gastroenteritis, while food poisoning is illness caused by contaminated food, including germs or toxins.
Stomach flu always causes fever, while food poisoning never does.
