ATI Pathophysiology Exam 1 Questions
Question 1 of 5
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?
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.
Question 2 of 5
What is the major effect of filgrastim (Neupogen) in a patient with chronic renal failure?
Correct Answer: A
Rationale: The major effect of filgrastim (Neupogen) is to stimulate the production of neutrophils, thereby decreasing neutropenia in patients undergoing chemotherapy. This medication helps the bone marrow produce more white blood cells, specifically neutrophils, to reduce the risk of infections associated with low neutrophil counts. Choices B, C, and D are incorrect because filgrastim does not decrease white blood cells related to infection, growth of blood vessels, or platelet count related to bleeding.
Question 3 of 5
An infant is being administered an immunization. Which of the following provides an accurate description of an immunization?
Correct Answer: B
Rationale: The correct answer is B. Immunization involves administering an antigen, such as a weakened or killed microorganism, to stimulate the immune system to produce an antibody response. This process helps the body recognize and remember specific pathogens, providing immunity against future infections. Choice A is incorrect because immunizations are administered to the infant directly, not to the pregnant woman before birth. Choice C is incorrect as there is no scientific evidence linking immunizations to autism. Choice D is incorrect as immunizations protect against infectious agents, not antibodies.
Question 4 of 5
Following the administration of her annual influenza vaccination, a health care worker remains at the clinic for observation due to pain at the injection site. What should the nurse recommend?
Correct Answer: B
Rationale: The correct recommendation for pain at the injection site after an influenza vaccination is Acetaminophen. Acetaminophen is a suitable choice for managing mild to moderate pain and fever commonly associated with vaccinations. Choice A, ASA (aspirin), is not recommended due to the risk of Reye's syndrome in children and teenagers following viral illnesses. Choice C, Meperidine (Demerol), is a potent opioid analgesic and is not typically indicated for mild pain relief. Choice D, heat application, is not the standard recommendation for pain at an injection site and may not provide adequate relief.
Question 5 of 5
A patient is hospitalized due to nonadherence to an antitubercular drug treatment. Which of the following is most important for the nurse to do?
Correct Answer: A
Rationale: In this scenario, the most crucial action for the nurse to take is to observe the patient taking the medications. This ensures that the patient is actually consuming the prescribed antitubercular drugs, addressing the issue of nonadherence directly. Administering the medications parenterally (intravenously or intramuscularly) is not necessary unless there are specific medical reasons requiring this route of administration. Instructing the family on the medication regimen is important for support but may not directly address the patient's nonadherence. Counting the number of tablets in the bottle daily is not as effective as directly observing the patient taking the medications to ensure compliance.
