Question 7

How are incidence and prevalence different?

Accepted Answer

Incidence measures new cases over a period of time, while prevalence measures cases at a specific point in time.

Answer

Prevalence measures new cases over a period of time, while incidence measures cases at a specific point in time.

Answer

Incidence measures the number of cases per population, while prevalence measures the proportion of cases in a population.

Prevalence measures the number of cases per population, while incidence measures the proportion of cases in a population.

Question 8

Which of the following is an example of a qualitative surveillance method in healthcare?

Accepted Answer

Conducting interviews with healthcare workers

Answer

Collecting data on infection rates

Answer

Examining environmental samples

Answer

Monitoring the use of antibiotics

Question 9

How does surveillance help prevent healthcare-associated infections like surgical site infections?

Accepted Answer

Surveillance identifies infection trends, allowing for targeted interventions.

Answer

Surveillance is only important during outbreaks, not for routine prevention.

Answer

Surveillance focuses on data collection, not infection prevention.

Answer

Surveillance is not essential for preventing surgical site infections.

Question 11

Which method of data collection is NOT typically used in surveillance?

Accepted Answer

Interviews, as they rely on individuals' recall and may be subject to biases and inaccuracies.

Answer

Reviewing medical records, involving examination of patient charts for relevant information on infections.

Answer

Environmental sampling, involving collection of samples from surfaces or air to detect the presence of pathogens.

Answer

Laboratory testing, involving analysis of clinical specimens to identify or confirm the presence of pathogens.

Question 12

What is the distinction between incidence and prevalence measures?

Accepted Answer

Incidence measures new cases of infection occurring over a specified period of time, while prevalence measures the total number of cases existing at a particular point in time.

Answer

Incidence measures the total number of cases existing at a particular point in time, while prevalence measures new cases of infection occurring over a specified period of time.

Question 13

What is the primary responsibility of healthcare professionals regarding surveillance?

Accepted Answer

Reporting suspected cases of infection and collecting data for surveillance purposes, contributing to the overall effectiveness of the surveillance system.

Answer
