CHAPTER 4 PRACTICE QUESTIONS

1. Which of the following is an essential data point for surveillance data collection?

a. HIPAA guidelines

b. Demographic information

c. Provider documentation

Answer: b

Rationale: Demographics (such as age, sex, race/ethnicity, and residence) are essential for surveillance systems to track disease trends, identify at-risk populations, and guide public health action.

2. Why is it important to collect essential data points during an interview with the person diagnosed with an infectious disease?

a. Essential data points are critical in building rapport and understanding.

b. Essential data points remain consistent regardless of disease.

c. Essential data points allow for the timely detection of health threats.

Answer: c

Rationale: Collecting consistent core data enables quick recognition of unusual patterns, clusters, or outbreaks, ensuring timely public health response.

3. How does a DI professional verify and collect important surveillance data when interviewing people diagnosed with or identified as possibly exposed to an infectious disease?

a. Review the importance of collecting data.

b. Use person-centric methods to extract essential demographic information.

c. Share information about the public health authorities' role in data collection.

Answer: b.

Rationale: Using respectful, person-centered interviewing techniques ensures accurate collection of critical demographic and epidemiological data while maintaining rapport and trust.

4. What is a potential consequence of inaccurate or incomplete documentation?

a. A delay in detecting an outbreak

b. A slowing of computer programs

c. An improved estimation of disease burden

Answer: a.

Rationale: If data are incomplete or incorrect, public health officials may miss warning signs of disease spread, leading to slower responses and increased transmission.

5. Why are the protection of privacy for the person diagnosed with the infectious disease, data confidentiality, and system security essential to maintaining the credibility of any surveillance system?

a. To protect against inappropriate use or release of that data

b. To gather more information from informal sources

c. To expedite the data collection process

Answer: a.

Rationale: Public trust in surveillance systems depends on strict protection of personal health data. Breaches can undermine participation and compromise system effectiveness.

6. Which of the following practices are important for ensuring accurate and complete surveillance data when documenting?

a. Uploading negative test results and excluding positive test results

b. Updating documentation once a new outbreak is declared

c. Regularly reviewing and updating the latest medical data relevant to infectious diseases

Answer: c.

Rationale: Ongoing review and updates ensure data accuracy and consistency, helping public health agencies maintain reliable surveillance records.

7. What is the primary purpose of conducting baseline surveillance?

a) To determine the effectiveness of surveillance procedures

b) To collect and interpret health data

c) To develop a starting point for disease monitoring

Answer: c.

Rationale: Baseline surveillance establishes the expected levels of disease occurrence, which allows health departments to detect unusual increases or decreases in disease activity
