Questions on Respiratory System Questions
Question 1 of 5
Which of the following factors predispose a client to the development of TB?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Priority Decision: To reduce the risk for most occupational lung diseases, what is the most important measure the occupational nurse should promote?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A nurse is caring for an older adult client who has a pulmonary infection. Which action should the nurse take first?
Correct Answer: B
Rationale: The correct action for the nurse to take first is to assess the client's level of consciousness (Choice B) because it is essential to determine the client's current neurological status and mental acuity, which can indicate the severity of the infection and the need for immediate interventions. Assessing consciousness helps in identifying any signs of respiratory distress or potential complications. Encouraging fluid intake (Choice A) is important but not the priority when the client's respiratory status is uncertain. Raising the head of the bed (Choice C) is beneficial for improving oxygenation but should come after assessing the client's consciousness. Providing humidified oxygen (Choice D) is important for respiratory support but should be based on the assessment findings.
Question 4 of 5
Fick's law of diffusion is related to
Correct Answer: A
Rationale: Fick's law of diffusion states that the rate of diffusion is directly proportional to the surface area and concentration gradient, and inversely proportional to the distance over which diffusion occurs. Therefore, Choice A - Diffusion and Surface area is correct because surface area directly affects the rate of diffusion. Choices B, C, and D are incorrect as they do not directly relate to Fick's law. B is incorrect as membrane potential is not a factor in Fick's law. C is incorrect as water content is not a key factor in the law of diffusion. D is incorrect as pore diameter is not explicitly mentioned in Fick's law.
Question 5 of 5
TB skin test is called 'Scatch test or Mantoux test' in which Tuberculin Purified Protein Derivative (PPD) is injected subcutaneously. This test is based on
Correct Answer: A
Rationale: The correct answer is A: Delayed Hypersensitivity. The TB skin test, also known as the Mantoux test, is based on the principle of delayed hypersensitivity reaction. When Tuberculin Purified Protein Derivative (PPD) is injected subcutaneously, in individuals previously exposed to TB, the immune system mounts a delayed hypersensitivity reaction resulting in localized inflammation at the injection site. This reaction is mediated by T cells and is indicative of previous exposure to the TB bacterium. Incorrect choices: B: Production of antibodies - The TB skin test does not detect the production of antibodies specific to TB, but rather the cellular immune response. C: Production of Tubercle toxin - The test is not based on the production of the tubercle toxin, but on the immune response to the tuberculin PPD. D: All these - While the immune response may involve various components, such as antibodies and cellular responses, the primary basis of the TB skin test is the
