1. Which of the following best describes epidemiology?

• A. The study of the distribution and determinants of health-related states or events in specified populations.
• B. The study of the distribution and determinants of health-related states or events in specified populations and the application of this study to control health problems.
• C. The study of how social factors influence health outcomes.
• D. The study of how health systems and services impact population health.

Correct answer: B

Rationale: Epidemiology is defined as the study of the distribution and determinants of health-related states or events in specified populations, as well as the application of this study to control health problems. This field focuses on identifying patterns and causes of health and disease in order to develop strategies for prevention and control.

2. In population health management, a nurse overseeing a panel of 1,500 patients will primarily engage in which of the following activities?

• A. Proactively assessing the health needs of the entire panel and planning accordingly
• B. Focusing on providing care to young and seemingly vulnerable patients
• C. Spending most time with patients who regularly attend their visits
• D. Prioritizing care by responding to the oldest patients first

Correct answer: A

Rationale: In population health management, a nurse overseeing a large panel of patients needs to proactively assess the health needs of the entire panel to plan and provide appropriate care effectively. This approach ensures that all patients receive necessary attention and interventions, contributing to better health outcomes for the population as a whole.

3. The public health nurse is reading information from a study that states that hypertension may be associated with an odds ratio of 2.49, meaning the patient is approximately 2.5 times more likely to have a severe form of COVID-19 than those without hypertension. The nurse describes the odds ratio as:

• A. a measure of association between an exposure and an outcome
• B. an absolute risk increase
• C. a measure of statistical significance
• D. a measure of precision

Correct answer: A

Rationale: The odds ratio is a measure of association between an exposure and an outcome. In this context, an odds ratio of 2.49 indicates that individuals with hypertension are approximately 2.5 times more likely to develop severe COVID-19 compared to those without hypertension. Therefore, choice A is correct as it accurately defines the role of odds ratio in assessing the relationship between an exposure (hypertension) and an outcome (severe COVID-19). Choices B, C, and D are incorrect as they do not describe the nature of odds ratio.

4. Which sign or reflex is used to diagnose meningitis?

• A. Homan's sign
• B. Brudzinski
• C. Startle
• D. Anterior drawer

Correct answer: B

Rationale: Brudzinski sign is a physical exam finding used to diagnose meningitis. It is elicited by flexing the patient's neck, resulting in involuntary flexion of the hips and knees. This maneuver indicates meningeal irritation, a common feature in meningitis. Homan's sign is used to assess for deep vein thrombosis, Startle is a reflex response to sudden stimuli, and the Anterior drawer test is used to diagnose ligamentous instability in the knee.

5. Which term describes a situation in which there is a demonstrated health need combined with actual or potential resources to apply remedial measures and a commitment to act on the part of the provider or the client?

• A. Health deficit
• B. Health need
• C. Health problem
• D. Foreseeable crisis

Correct answer: C

Rationale: A health problem specifically refers to a situation where a health need is identified, resources are available or potentially available to address it, and there is a commitment from either the provider or the client to take action. This term encapsulates the combination of a demonstrated need for remedial measures with the readiness and commitment to act upon it.
