ATI Community Health Proctored Exam 2019 Quizlet
1. Sputum examination is the major screening tool for pulmonary tuberculosis. Clients may sometimes receive false negative results in this exam. This means that the test is not perfect in terms of which characteristic of a diagnostic examination?
- A. Effectiveness
- B. Efficacy
- C. Specificity
- D. Sensitivity
Correct answer: D
Rationale: Sensitivity is the ability of a diagnostic test to correctly identify individuals with the disease. A test with high sensitivity will rarely give false negative results, as it will detect almost all positive cases. In the context of the given scenario, false negative results indicate that the test is lacking in sensitivity to pick up all cases of pulmonary tuberculosis, leading to some cases being missed.
2. 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: Cyclical variation best describes the periodic fluctuation in the number of Dengue fever cases in the community, typically increasing towards the end of the rainy season and then decreasing during drier periods. This pattern suggests a recurring cycle rather than a sudden outbreak (epidemic), random occurrence (sporadic), or gradual long-term change (secular occurrence).
3. What is the primary purpose of administering Vitamin K to newborns?
- A. To prevent infection
- B. To promote growth
- C. To prevent bleeding disorders
- D. To enhance immune function
Correct answer: C
Rationale: Vitamin K is administered to newborns primarily to prevent bleeding disorders. Newborns have low levels of Vitamin K at birth, which can lead to a condition called vitamin K deficiency bleeding (VKDB). Administering Vitamin K helps prevent this potentially life-threatening bleeding disorder.
4. What is the primary purpose of conducting an epidemiologic investigation?
- A. Delineate the etiology of the epidemic
- B. Encourage cooperation and support of the community
- C. Identify groups at risk of contracting the disease
- D. Identify the geographical locations of disease cases in the community
Correct answer: A
Rationale: The primary purpose of conducting an epidemiologic investigation is to delineate the etiology of the epidemic, which involves identifying the cause or origin of the disease outbreak. This process helps in understanding how the disease spreads, its risk factors, and developing strategies for control and prevention.
5. During which step are plans formulated for solving community problems?
- A. Mobilization
- B. Community organization
- C. Follow-up/extension
- D. Core group formation
Correct answer: B
Rationale: Community organization is the step where community assemblies occur. It is during these assemblies that the community formalizes its organization and develops plans for community action to address a community health issue. This step is crucial for coordinating efforts and resources towards solving community problems effectively.
