In the investigation of an epidemic, you compare the present frequency of the disease with the usual frequency at this time of the year in this community. This is done during which stage of the investigation?
- A. Establishing the epidemic
- B. Testing the hypothesis
- C. Formulation of the hypothesis
- D. Appraisal of facts
Correct Answer: A
Rationale: The correct answer is A: Establishing the epidemic. During this stage, comparing the present disease frequency with the usual frequency helps determine if there is a significant increase, indicating an epidemic. This step is crucial for recognizing and confirming the outbreak. Testing the hypothesis (B) comes after the epidemic is established. Formulation of the hypothesis (C) involves developing a theory based on observations, not comparing frequencies. Appraisal of facts (D) occurs after data collection, not during the initial comparison.
When the occupational health nurse employs ergonomic principles, they are performing which of their roles?
- A. Health care provider
- B. Health educator
- C. Health care coordinator
- D. Environment manager
Correct Answer: D
Rationale: The correct answer is D, Environment manager. By utilizing ergonomic principles, the occupational health nurse is focusing on designing and managing the work environment to optimize safety and efficiency. This includes adjusting equipment, layout, and processes to prevent injuries and promote well-being. A health care provider (A) focuses on diagnosing and treating health conditions, not environment management. Health educator (B) involves providing information and guidance on health-related topics, not specifically environment management. Health care coordinator (C) involves coordinating care among different healthcare providers, which is not directly related to the application of ergonomic principles in the work environment.
As the public health nurse in a municipality with a total population of about 20,000 and 3 health midwives among the RHU personnel, how many more midwife positions will the RHU need?
- A. 1
- B. 2
- C. 3
- D. 4
Correct Answer: A
Rationale: The correct answer is A: 1. With a total population of about 20,000, the ideal ratio is 1 midwife per 5,000 people. Currently, there are 3 midwives for 20,000 people (1:6,666). To reach the ideal ratio, the RHU needs 1 more midwife.
Choice B, C, and D are incorrect because they would exceed the ideal ratio of 1 midwife per 5,000 people, leading to inefficiency and potentially underutilizing resources.
The number of cases of Dengue fever usually increases towards the end of the rainy season. This pattern of occurrence of Dengue fever is best described as:
- A. Epidemic occurrence
- B. Cyclical variation
- C. Sporadic occurrence
- D. Secular occurrence
Correct Answer: B
Rationale: Step 1: Cyclical variation refers to a pattern that repeats at regular intervals.
Step 2: The increase in Dengue fever cases at the end of the rainy season is a recurring pattern.
Step 3: The rise in cases is linked to the environmental conditions during the rainy season.
Step 4: This cyclic increase in cases is not a sudden outbreak (epidemic) or random (sporadic).
Step 5: Secular occurrence refers to long-term trends, not short-term patterns like the end of a season.
Summary: Choice B is correct because the pattern of Dengue fever cases increasing at the end of the rainy season aligns with cyclical variation, unlike the other options which do not accurately describe this specific pattern.
A business firm must employ an occupational health nurse when it has at least how many employees?
- A. 21
- B. 101
- C. 201
- D. 301
Correct Answer: B
Rationale: The correct answer is B (101 employees) because the Occupational Safety and Health Administration (OSHA) regulations require a business to have an occupational health nurse when the workforce reaches 101 employees. Employing an occupational health nurse at this threshold ensures that the company complies with OSHA standards for employee health and safety.
Choices A, C, and D are incorrect because they do not align with the specific OSHA requirement of 101 employees for employing an occupational health nurse. Option A (21 employees) is too low, and options C (201 employees) and D (301 employees) exceed the required threshold. Therefore, only option B meets the OSHA regulation criteria for when a business must employ an occupational health nurse.
