A nurse is assessing an outbreak of mumps among school-age children. Using the epidemiological triangle, the nurse should recognize that which of the following is the host?
- A. The vaccine
- B. The virus
- C. The school
- D. The children
Correct Answer: D
Rationale: The correct answer is D: The children. In the epidemiological triangle, the host refers to the organism that harbors the disease. In this case, the school-age children are the host as they are the ones affected by the mumps virus. The virus (option B) is the agent causing the disease, the vaccine (option A) is a preventative measure, and the school (option C) is the environment where transmission may occur but not the host. Therefore, the children (option D) being the individuals who are infected and affected by the mumps outbreak, are correctly identified as the host in this scenario.

A community health nurse is planning a program for adolescents about preventing STIs. Which of the following actions should the nurse take first?
- A. Collect data to identify barriers to learning
- B. Establish methods to evaluate program outcomes
- C. Obtain visual aids that feature adolescents
- D. Provide computer-based education
Correct Answer: A
Rationale: The correct answer is A: Collect data to identify barriers to learning. This should be the first step because understanding the specific challenges and obstacles that adolescents face in learning about preventing STIs is crucial for designing an effective program. By collecting data, the nurse can tailor the program to address the specific needs of the target audience, ensuring that the information is relevant and accessible.
Choice B, establishing methods to evaluate program outcomes, would come later in the program planning process after the content has been developed and implemented. Choice C, obtaining visual aids featuring adolescents, and choice D, providing computer-based education, are also important but should be considered after identifying barriers to learning to enhance the effectiveness of the program.
A nurse is teaching a prenatal class about infection prevention at a community center. Which of the following statements by a client indicates an understanding of the teaching?
- A. I should take antibiotics when I have a virus.
- B. I can visit my nephew who has chickenpox 5 days after the sores have crusted.
- C. I can clean my cat's litter box during my pregnancy.
- D. I should wash my hands for 10 seconds with hot water after working in the garden.
Correct Answer: B
Rationale: The correct answer is B: I can visit my nephew who has chickenpox 5 days after the sores have crusted. This answer demonstrates understanding of infection prevention because chickenpox is contagious until the sores have crusted over completely. Visiting the nephew after this period reduces the risk of contracting the virus.
Incorrect answers:
A: Taking antibiotics for a virus is ineffective as antibiotics only work against bacterial infections.
C: Cleaning a cat's litter box can expose the client to toxoplasmosis, a harmful parasite during pregnancy.
D: Washing hands for only 10 seconds with hot water is insufficient for proper hand hygiene; CDC recommends washing for at least 20 seconds.
A nurse is providing teaching to a 50-year-old female client. Which of the following statements should the nurse include in the teaching?
- A. You should have a complete eye examination every 2 years until the age of 64
- B. You should have your hearing screened every 5 years
- C. You should have your stool tested for blood every other year until the age of 74
- D. You should have your fasting blood glucose level checked every 6 years
Correct Answer: A
Rationale: Correct Answer: A - You should have a complete eye examination every 2 years until the age of 64.
Rationale: Regular eye exams help detect common eye conditions such as glaucoma and cataracts early, especially as people age. The American Academy of Ophthalmology recommends eye exams every 2 years for adults aged 40-64. This statement is important for the client's eye health maintenance.
Summary of other choices:
B: Incorrect - Hearing screenings are typically recommended annually for adults over 50, not every 5 years.
C: Incorrect - Stool tests for blood are usually done every year, not every other year until the age of 74, to screen for colorectal cancer.
D: Incorrect - Fasting blood glucose levels should be checked more frequently, at least every 3 years, for early detection of diabetes.
A community health nurse is providing screening for lipid disorders. Which of the following is the primary goal of this activity?
- A. Early detection of disease
- B. Client enrollment in prevention programs
- C. Promotion of appropriate lifestyle changes
- D. Identification of family history of medical problems
Correct Answer: A
Rationale: The correct answer is A: Early detection of disease. The primary goal of screening for lipid disorders is to identify individuals at risk for developing lipid disorders such as high cholesterol levels. Early detection allows for timely intervention and treatment to prevent complications like heart disease. Choice B is incorrect because enrollment in prevention programs is a secondary outcome of screening, not the primary goal. Choice C is also incorrect as promoting lifestyle changes is a part of the intervention phase, not the primary goal of screening. Choice D is incorrect as identifying family history is important but not the primary goal of screening for lipid disorders.
A home health nurse is planning the initial home visit for a client who has dementia and lives with his adult son's family. Which of the following actions should the nurse take first during the visit?
- A. Encourage the family to join a support group
- B. Provide the family with information about respite care
- C. Educate the family regarding the progression of dementia
- D. Engage the family in informal conversation
Correct Answer: D
Rationale: The correct answer is D: Engage the family in informal conversation. This is the first action the nurse should take during the initial visit because building rapport and establishing trust with the family is crucial in the care of a client with dementia. By engaging in informal conversation, the nurse can observe family dynamics, assess the family's understanding of the client's condition, and gather valuable information about the client's daily routine and needs. This lays the foundation for effective communication and collaboration moving forward.
A: Encouraging the family to join a support group can be beneficial but should come after establishing rapport and assessing the family's needs.
B: Providing information about respite care is important, but it is not the priority during the initial visit.
C: Educating the family about the progression of dementia is important, but it should be done after building rapport and assessing their current understanding.
