ATI Pathophysiology Test Bank Questions
Question 1 of 5
Innate resistance or immunity:
Correct Answer: D
Rationale: Innate resistance or immunity relies on the body's natural defenses like physical, mechanical, and biochemical barriers. These barriers act as the first line of defense against pathogens and do not involve memory (choice A). Innate immunity is present from birth and does not develop over an individual's later years (choice B). Additionally, innate immunity is a rapid and nonspecific process, not a slow and specific one (choice C). Therefore, the correct answer is D.
Question 2 of 5
A nurse practitioner is seeing a client in the clinic with a suspected diagnosis of bacterial meningitis. What should the nurse anticipate as the priority action?
Correct Answer: A
Rationale: The correct answer is to administer the first dose of antibiotics immediately after blood cultures are drawn for suspected bacterial meningitis. This is crucial to initiate treatment promptly and improve patient outcomes. Starting an IV line and administering corticosteroids (Choice B) may be part of the treatment plan but administering antibiotics is the priority. Isolating the client (Choice C) is important to prevent the spread of infection but not the priority over initiating antibiotic therapy. Performing a lumbar puncture (Choice D) may confirm the diagnosis, but treatment should not be delayed for this step in suspected cases of bacterial meningitis.
Question 3 of 5
A nurse is providing education to a patient starting hormone replacement therapy (HRT) for menopausal symptoms. What should the nurse emphasize regarding the long-term risks associated with HRT?
Correct Answer: A
Rationale: HRT is associated with an increased risk of cardiovascular events, including heart attack and stroke, particularly with long-term use.
Question 4 of 5
During a follow-up visit, a patient being treated for latent tuberculosis mentions inconsistent drug intake. What should subsequent health education focus on?
Correct Answer: B
Rationale: The correct answer is B because consistent intake of prescribed drugs is crucial for curing tuberculosis. By emphasizing the necessity of following the treatment plan, the patient is more likely to achieve a successful outcome. Choice A is incorrect because it focuses on the risk of adverse effects rather than the primary goal of TB cure. Choice C is incorrect as it does not address the issue of inconsistent drug intake. Choice D is also incorrect as it introduces a different treatment (antiretrovirals) not relevant to latent tuberculosis.
Question 5 of 5
During a late-night study session, a pathophysiology student reaches out to turn the page of her textbook. Which component of her nervous system contains the highest level of control of her arm and hand action?
Correct Answer: A
Rationale: The correct answer is A: Cerebral cortex. The cerebral cortex, particularly the motor cortex, is responsible for the voluntary control of precise movements such as turning a page. The cerebral cortex plays a crucial role in the highest level of control of motor functions, including those of the arm and hand. Choice B, Basal ganglia, is more involved in motor planning and coordination, while choice C, Brainstem, is responsible for basic life functions and reflexes. Choice D, Cerebellum, is primarily involved in coordination, precision, and accurate timing of movements, rather than the highest level of control for specific actions like page-turning.
