Guaranteed protection against every respiratory virus
Treatment for an influenza infection that has already begun
Prevention of common colds caused by all cold viruses
2. Which statement about prescription influenza antivirals is accurate?
They work best when started early, though later treatment may still help in severe or high-risk cases
They cure common colds by eliminating every respiratory virus
They are another name for antibiotics
They are useful only after all symptoms have resolved
3. Which habit can directly help reduce transmission of both cold and influenza viruses?
Sharing cups only with people who have mild symptoms
Cleaning hands regularly and covering coughs and sneezes
Avoiding all outdoor activity during cold weather
Taking antibiotics immediately after exposure
4. Which condition can occur as a serious complication of influenza?
Seasonal pollen allergy
Pneumonia
Permanent immunity to all future flu strains
A common cold caused by influenza changing into a cold virus
5. An older adult with chronic lung disease develops sudden flu-like symptoms today. What is the most appropriate next step?
Wait several weeks because treatment decisions never depend on timing
Start leftover antibiotics without medical advice
Assume it is a mild cold unless nasal symptoms disappear
Contact a healthcare professional promptly to discuss testing and antiviral treatment
6. Which symptom pattern is generally more characteristic of influenza than of a common cold?
Gradual sneezing with a mildly stuffy nose
Itchy eyes that recur during pollen season
Abrupt fever, chills, body aches, and marked fatigue
Nasal congestion without broader symptoms
7. After several days of improvement, a person’s fever returns and their cough becomes worse. What is the soundest response?
Assume the returning fever is a normal sign of recovery
Double every over-the-counter medicine being used
Use antibiotics left over from a previous illness
Contact a healthcare professional because worsening after improvement can signal a complication
8. Lee wants to take a cold remedy and a separate pain reliever. What should Lee check first?
Whether they contain the same active ingredient, such as acetaminophen, to avoid an accidental overdose
Whether one product is labeled for nighttime use
Whether both products use different brand colors
Whether taking twice the labeled amount could shorten the illness
9. What is the most accurate conclusion when a person has cough, sore throat, congestion, and fatigue?
The symptoms prove that the person has influenza
Congestion proves that the illness is a common cold
Several respiratory illnesses can cause this combination, so symptoms alone may not identify the cause
The combination rules out COVID-19 and other infections
10. Jordan felt well in the morning but developed fever, chills, strong muscle aches, and exhaustion by evening. Which illness does this pattern more strongly suggest?

Influenza, because it often has a sudden, systemic onset

Those symptoms can occur only with influenza
A cough reliably rules out a common cold
Flu, COVID-19, and other infections can produce overlapping symptoms

Both always produce a high fever
Both are caused by the same type of bacterium
Both are caused by viruses
Both can be confirmed by the same home symptom checklist

Antibiotics work only when a viral fever is very high
Antibiotics target bacteria, not the viruses that cause colds and flu
Antibiotics prevent symptoms but cannot shorten an illness
Antibiotics treat influenza but not nasal congestion
