Answer to Question 1

ANS: B
Standard precautions need to be used for all patients. Droplet precautions are used for patients known or suspected to have serious illnesses transmitted by large-particle droplets. Influenza is a serious viral infection spread by droplet transmission. Contact isolation is used for patients known or suspected to have serious illnesses easily transmitted by direct patient contact or by contact with items in the patient's environment. Airborne precautions should be used for patients who are known or suspected to have illnesses transmitted by airborne droplet nuclei, such as measles, varicella, or tuberculosis.

Answer to Question 2

ANS: C
Ventilator tubing comes in contact with intact mucous membranes and is considered semicritical. Critical items are those that are introduced into sterile tissue or the vascular system. Noncritical items come in contact with intact skin. Noncritical items include face masks, ventilators, stetho-scopes, and blood pressure cuffs. Highly critical is not a descriptor that Spaulding used.
