ATI Pathophysiology Exam 1
1. A patient with severe peripheral vascular disease has developed signs of dry gangrene on the great toe of one foot. Which of the following pathophysiologic processes most likely contributed to this diagnosis?
- A. Inappropriate activation of apoptosis
- B. Bacterial invasion
- C. Impaired arterial blood supply
- D. Metaplastic cellular changes
Correct answer: C
Rationale: The correct answer is C: Impaired arterial blood supply. Dry gangrene is typically caused by impaired arterial blood supply, leading to tissue death without bacterial infection. Choices A, B, and D are incorrect. Inappropriate activation of apoptosis is not a common cause of dry gangrene. Bacterial invasion usually leads to wet gangrene, not dry gangrene. Metaplastic cellular changes are not directly associated with the development of dry gangrene.
2. Which of the following is found in higher concentrations within intracellular fluid?
- A. Magnesium
- B. Sodium
- C. Chloride
- D. Bicarbonate
Correct answer: A
Rationale: Magnesium is the correct answer as it is found in higher concentrations within intracellular fluid, where it plays vital roles in various cellular functions. Sodium, chloride, and bicarbonate are predominantly found in extracellular fluid rather than intracellular fluid, making them incorrect choices for this question.
3. Which of the following outcome criteria is appropriate for a client with dementia?
- A. The client will return to an established schedule for activities of daily living.
- B. The client will learn new coping mechanisms to handle anxiety.
- C. The client will seek out resources in the community for support.
- D. The client will follow an established schedule for activities of daily living.
Correct answer: D
Rationale: The correct answer is D. For clients with dementia, following an established schedule for activities of daily living is appropriate as it helps maintain routine and structure, which can be beneficial for their condition. Choice A has been rephrased to align better with the context of dementia care. Choice A is incorrect as expecting a return to a previous level of self-functioning may not be realistic for clients with dementia. Choice B is not the most appropriate outcome criteria as handling anxiety, while important, may not be the primary focus when working with clients with dementia. Choice C, seeking out resources in the community for support, is also important but may not be as directly related to the day-to-day care and management of activities for a client with dementia.
4. What occurs in a client with polycythemia?
- A. Deficient plasma in the blood
- B. Increased lymphatic fluid being produced
- C. Increased red blood cells being produced
- D. Deficient number of red blood cells
Correct answer: C
Rationale: The correct answer is C: Increased red blood cells being produced. Polycythemia is a condition characterized by an elevated number of red blood cells in the blood. This increased concentration of red blood cells can lead to blood thickening and potentially result in complications such as blood clots. Choices A, B, and D are incorrect because polycythemia does not involve deficient plasma, increased lymphatic fluid production, or a deficient number of red blood cells.
5. What type of immunity will the hepatitis B series provide a nursing student scheduled to receive it?
- A. Active immunity
- B. Passive immunity
- C. Innate immunity
- D. Natural immunity
Correct answer: A
Rationale: The correct answer is active immunity. The hepatitis B series immunization will provide active immunity, where the individual's immune system is stimulated to produce antibodies against the hepatitis B virus. This type of immunity is long-lasting and provides protection against future exposures. Passive immunity (choice B) involves the transfer of pre-formed antibodies and is temporary. Innate immunity (choice C) is the body's natural defense mechanisms, present at birth. Natural immunity (choice D) refers to immunity acquired through normal life processes, such as recovering from an infection.
