Answer to Question 1
Correct Answer: 1,2,3
Rationale 1: Bacteria residing in the lungs are a source of HAIs.
Rationale 2: Bacteria residing in the genitourinary tract are a source of HAIs.
Rationale 3: Invasive devices such as IV lines are a source of HAIs.
Rationale 4: HAIs are infections that are acquired in a health care setting, not caused by visitors.
Rationale 5: Drug-resistant bacteria may be the result, not the source, of HAIs.
Global Rationale: HAIs are generally from one of four sources: patient flora, invasive devices, medical personnel, or the medical environment. Invasive devices are often inserted into the respiratory system and the GU system.
Answer to Question 2
Correct Answer: 1,2,3
Rationale 1: It is easier to prevent an infection than it is to treat one.
Rationale 2: The causative organism must be identified and the correct antibiotic prescribed. This will lower the risk of developing resistance.
Rationale 3: The unwarranted use of antibiotics has promoted the development of drug-resistant bacteria.
Rationale 4: Antibiotics must be taken for the entire prescribed time. This will help prevent the development of resistant bacteria.
Rationale 5: Some antibiotics must be taken for longer than 10 days. It is important to take an antibiotic for the prescribed duration.
Global Rationale: Methods of delaying the emergence of antibiotic resistance include preventing infections when possible, diagnosing and treating infections properly, using antimicrobials wisely, and preventing disease transmission.
