Which of the following are considered portals of exit in the chain of infection? (Select all that apply.)

1. A bleeding cut
2. A hardy sneeze
3. A kiss on the lips
4. A urinary catheter
5. A scraped knuckle
6. A friendly handshake

Question 2

The nurse is educating a client diagnosed with type 2 diabetes, who is susceptible to foot wounds, on how to minimize the risk for infection related to poor wound healing by not being a susceptible host. The most appropriate suggestion would be to:

1. Inspect feet and legs daily for skin breakdown
2. See a podiatrist regularly for appropriate foot care
3. Keep blood sugar levels within normal range to maximize the ability to heal
4. Eat well-balanced meals in order to provide the nutrients necessary for healing

Answer to Question 1

ANS: 1, 2, 3, 4, 5
After microorganisms find a site to grow and multiply, they must find a portal of exit if they are to enter another host and cause disease. Portals of exit include sites such as blood, skin/mucous membranes, respiratory tract, genitourinary tract, gastrointestinal tract, and transplacental (mother to fetus). Unless the skin of the hands was broken (not intact), this contact would not be consid-ered a portal of exit.

Answer to Question 2

ANS: 4
Good infection control begins with prevention. Review with clients and their families preventive measures to strengthen their defenses. In the case of a diabetic client, keeping blood sugar levels within normal limits maximizes the client's ability to both heal and fight infection. While the other options are not incorrect, they are more directed towards healing than prevention.
