Welcome to another weekend of Medical Trivia! Here are the answers to this week's questions, with explanations for each correct option and why the others don’t quite fit.
Monday:
Which type of headache is often accompanied by nausea and sensitivity to light?
Answer: C. Migraine
Explanation:
Migraines are known for their intense, throbbing pain, often accompanied by nausea, vomiting, and sensitivity to light and sound. They can last hours or even days and significantly impact daily life.
A. Tension headache: This is the most common type of headache, characterized by a dull, aching pain but without the nausea or light sensitivity typical of migraines.
B. Cluster headache: These are extremely painful but are not commonly associated with nausea or light sensitivity. They usually occur in cycles or "clusters."
D. Sinus headache: Caused by sinus infections, these headaches are associated with facial pain and nasal congestion, not the systemic symptoms seen in migraines.
Tuesday:
A person suddenly collapses and is unresponsive. What is the first thing you should do?
Answer: A. Call for help
Explanation:
The first step in responding to an emergency is to call for help. Alerting emergency services ensures that professional help is on the way while you assess and provide first aid.
B. Check for breathing: This is an important step, but only after ensuring that help has been called.
C. Start CPR: This should be done if the person is not breathing, but it’s not the very first step.
D. Shake the person: While checking for responsiveness is crucial, shaking someone is not recommended as it could cause harm, especially if there’s a spinal injury.
Wednesday:
Which nutrient helps with wound healing?
Answer: B. Vitamin C
Explanation:
Vitamin C is essential for collagen synthesis, which is crucial for wound healing. It also boosts the immune system, helping to prevent infections during recovery.
A. Vitamin D: Important for bone health and immune function, but it doesn’t play a direct role in wound healing.
C. Vitamin A: This supports skin health and immune function but is less directly involved in the collagen synthesis process.
D. Vitamin B12: Crucial for nerve function and red blood cell production but not directly related to wound healing.
Thursday:
Which type of infection does an antibiotic treat?
Answer: C. Bacterial
Explanation:
Antibiotics are designed to target and kill bacteria or inhibit their growth. They’re effective against bacterial infections like strep throat, urinary tract infections, and pneumonia.
A. Viral: Antibiotics don’t work against viruses. Conditions like the common cold and flu are caused by viruses and require other treatments.
B. Fungal: Antifungal medications, not antibiotics, treat fungal infections like athlete’s foot or yeast infections.
D. Parasitic: Parasites require antiparasitic medications, not antibiotics.
Friday:
What is the most common cause of peptic ulcers?

Most peptic ulcers are caused by an infection with Helicobacter pylori (H. pylori), a bacteria that damages the stomach lining. Treatment typically involves antibiotics and acid-reducing medications.
A. Spicy food: While spicy foods can aggravate symptoms, they don’t cause ulcers.
B. Stress: Once thought to be a primary cause, stress is now known to exacerbate but not directly cause ulcers.
D. Alcohol: Alcohol can irritate the stomach lining but is not the leading cause of ulcers.
