Question

which medication is a non - drowsy second - generation antihistamine? *
○ diphenhydramine
○ loratadine
○ dextromethorphan
○ aspirin

which heartburn medication gives almost immediate relief by neutralizing stomach acid? * 1 point
○ omeprazole
○ famotidine
○ calcium carbonate
○ loperamide

Explanation:

• First question:
• Diphenhydramine is a first - generation antihistamine with sedative effects.
• Loratadine is a second - generation antihistamine that is non - drowsy as it has less penetration through the blood - brain barrier.
• Dextromethorphan is a cough suppressant, not an antihistamine.
• Aspirin is a non - steroidal anti - inflammatory drug (NSAID), not an antihistamine.
• Second question:
• Omeprazole is a proton pump inhibitor that reduces acid production over time (not immediate).
• Famotidine is a histamine - 2 receptor antagonist that reduces acid production (not immediate neutralization).
• Calcium carbonate is an antacid that neutralizes stomach acid quickly.
• Loperamide is an antidiarrheal drug, not related to heartburn treatment.

Answer:

1. Loratadine
2. Calcium carbonate
