Chapter 71 : Management of Patients With Infectious Diseases Questions
Question 1 of 5
When a disease infects a host a portal of entry is needed for an organism to gain access. What has been identified as the portal of entry for tuberculosis?
Correct Answer: C
Rationale: Tuberculosis is transmitted via inhalation of airborne droplets, making the respiratory system the primary portal of entry.
Question 2 of 5
A patient has a concentration of S. aureus located on his skin. The patient is not showing signs of increased temperature, redness, or pain at the site. The nurse is aware that this is a sign of a microorganism at which of the following stages?
Correct Answer: B
Rationale: Colonization indicates the presence of microorganisms without host symptoms or immune response. Infection, disease, and bacteremia involve symptomatic host interactions.
Question 3 of 5
An infectious outbreak of unknown origin has occurred in a long-term care facility. The nurse who oversees care at the facility should report the outbreak to what organization?
Correct Answer: A
Rationale: The CDC is responsible for disease prevention and control, making it the appropriate agency for reporting outbreaks. AMA, EPA, and ANA do not handle outbreak reporting.
Question 4 of 5
The infectious control nurse is presenting a program on West Nile virus for a local community group. To reduce the incidence of this disease, the nurse should recommend what action?
Correct Answer: C
Rationale: West Nile virus is transmitted by mosquitoes, so repellants are the most effective prevention. No vaccine exists, and handwashing or wound covering are less specific.
Question 5 of 5
An immunosuppressed patient is receiving chemotherapy treatment at home. What infection-control measure should the nurse recommend to the family?
Correct Answer: C
Rationale: A clean but non-sterile home environment is sufficient for immunosuppressed patients, as intrinsic bacteria pose greater risks than environmental ones. Avoiding vaccinations or contact is unnecessary, and daily bleach cleaning is excessive.
