Rationale: Flashlight, supply of batteries, battery-operated radio, and extra pair of eye-glasses should be identified as items to have on hand as part of disaster preparedness. A 3-day supply of water is recommended (1 gallon per person per day). Similarly, a 3-day supply of nonperishable food is recommended. A 3-week supply of water and food is unnecessary and not recommended.
Answer to Question 2

Rationale: The signs and symptoms worsen as the carbon monoxide level rises in the bloodstream. Impaired visual acuity occurs at 5 to 10, whereas flushing and headache are seen at 11 to 20. Nausea and impaired dexterity appear at levels of 21 to 30, and a 31 to 40 level is accompanied by vomiting, dizziness, and syncope. Levels of 41 to 50 cause tachypnea and tachycardia, and those higher than 50 result in coma and death.
