Answer to Question 1
ANS: B
A normal defense mechanism against infection in the respiratory tract is the cilia lining the upper airways of the lungs and normal mucus. When a patient inhales a microbe, the cilia and mucus trap the microbe and sweep them up and out to be expectorated or swallowed. Smoking may alter this defense mechanism and increase the patient's potential for infection. Smoking can be expensive, the smell does cling to hair and clothing, and the tar within the smoke can alter the color of a patient's nails. This information can be included in the education but does not constitute the most important point.
Answer to Question 2
ANS: C
Rocky Mountain spotted fever is caused by bacteria transmitted by the bite of ticks. Wearing a repellent that is designed for repelling ticks, mosquitoes, and other insects can help in preventing transmission of this disease. Drinking plenty of uncontaminated water, wearing sunscreen, and using alcohol-based hand gels for cleaning hands are all important activities to participate in while camping, but they do not contribute to or prevent transmission of this disease.
