Allergy Quiz
Questions: 16 · 10 minutes
1. A child with a known food allergy develops hives, wheezing, and trouble breathing shortly after eating. What is the most appropriate response?
Give food or drink to dilute the allergen.
Wait to see whether the breathing problem settles without treatment.
Follow the emergency plan, use prescribed epinephrine promptly, and call emergency services.
Rely only on skin cream because hives are visible.
2. Someone with pollen allergy has spent several hours outdoors on a high-pollen day. Which step may reduce the pollen carried into their sleeping area?
Leave the bedroom window open overnight to circulate outdoor air.
Dry worn clothing beside the bed before using it again.
Change clothes and shower before going to bed.
Mow the lawn in the evening to remove flowering grass.
3. Someone is trying to reduce exposure to dust-mite allergens in bed. Which measure is specifically designed for that purpose?
Use a room humidifier continuously.
Spray bedding with a scented air freshener.
Keep extra fabric cushions on the bed to absorb dust.
Use allergen-impermeable covers on the mattress and pillows.
4. What is the main aim of allergen immunotherapy when it is medically appropriate?
To identify every substance that could ever cause symptoms
To provide immediate emergency treatment during anaphylaxis
To gradually reduce sensitivity and symptoms through controlled allergen exposure
To guarantee that no future allergic reaction can occur
5. During food preparation, which practice best reduces allergen cross-contact?
Wipe a shared utensil on a dry towel between foods.
Use thoroughly cleaned or separate utensils and preparation surfaces.
Cook the allergen-containing food at a higher temperature.
Prepare the allergen-free food beside the other dish to compare ingredients.
6. An itchy rash appears where a nickel-containing watchband repeatedly touches the skin, often hours after contact. Which process best fits this pattern?
Allergic contact dermatitis, a delayed skin reaction
A digestive intolerance to metal
An immediate food-allergy reaction
A contagious skin infection spread by the watchband
7. What best describes an allergic reaction?
The body cannot digest a particular nutrient because an enzyme is missing.
The immune system reacts to a substance that is usually harmless to most people.
A microorganism directly infects the body after contact with food or pollen.
The body becomes dependent on a substance after repeated exposure.
8. Why can an allergy test alone be insufficient to diagnose a clinical allergy?
A negative result always confirms that symptoms have a non-allergic cause.
Allergy tests detect intolerances but cannot detect immune responses.
Test results are useful only during an active severe reaction.
A positive result can show sensitization without proving that exposure causes symptoms.
9. A person uses prescribed epinephrine for a severe allergic reaction and feels much better within minutes. What should happen next?
They should resume normal activity if all symptoms have stopped.
They should take a nap so the body can recover.
They need medical care only if a rash remains the next day.
They should still seek emergency medical help because symptoms can return or require further treatment.
10. What is the recommended first-line medication for suspected anaphylaxis?
Epinephrine, given promptly according to the emergency plan
A topical corticosteroid cream
An antacid
An oral decongestant
11. A packaged snack lists a person's known food allergen as an ingredient. What is the appropriate choice?
Eat a small amount because packaged foods contain only trace quantities.
Do not eat it and choose an alternative that does not list the allergen.
Remove visible pieces of the ingredient and eat the rest.
Heat the snack thoroughly because cooking reliably removes all allergens.
12. How does lactose intolerance usually differ from a milk allergy?
Lactose intolerance involves difficulty digesting lactose, while milk allergy involves an immune response to milk proteins.
Lactose intolerance is always more dangerous than a milk allergy.
Lactose intolerance affects only the skin, while milk allergy affects only digestion.
Lactose intolerance begins immediately after any contact, while milk allergy is always delayed.
13. What do antihistamines mainly do in many mild allergic reactions?
Destroy allergen particles before they enter the body
Permanently retrain the immune system after one dose
Block the effects of histamine to reduce symptoms such as itching or sneezing
Confirm which substance caused the reaction
14. A skin-prick test produces a raised bump for one substance. What is the most accurate interpretation?
It suggests sensitization and must be interpreted alongside symptoms and medical history.
It proves that any exposure will cause a severe reaction.
It confirms that the substance must be avoided for life.
It shows that the immune system has no tolerance for related substances.
15. After an insect sting, which symptom combination is most concerning for a severe systemic allergic reaction?
Mild pain and a small area of redness at the sting site
Throat tightness with dizziness or faintness
A stuffy nose beginning the following day
Itching limited to the skin directly around the sting
16. Which pattern is more suggestive of allergic rhinitis than a typical viral cold?
High fever with muscle aches and chills
Sudden vomiting after eating spoiled food
A sore throat followed by several days of fever
Repeated sneezing with itchy, watery eyes after a predictable exposure
