ATI Pathophysiology Final Exam Questions
Question 1 of 5
During surgery, the anesthesia personnel notice the client is having a steady rise in end-tidal carbon dioxide level. At this time, the nurse anesthetist begins to assess the client for malignant hyperthermia. The initial (priority) assessment for this disorder may include:
Correct Answer: B
Rationale: The correct answer is B: monitoring for muscle rigidity. Muscle rigidity is a hallmark sign of malignant hyperthermia, a life-threatening condition triggered by certain anesthetics. Monitoring for this sign is critical in the early identification of the condition. Choices A, C, and D are not the initial priority assessments for malignant hyperthermia. Measuring serum potassium levels, evaluating renal function, and checking arterial blood gases are not specific initial assessments for malignant hyperthermia and would not aid in its early identification.
Question 2 of 5
Which of the following mediators of inflammation causes increased capillary permeability and pain?
Correct Answer: C
Rationale: Bradykinin is the correct answer. It is a potent mediator of inflammation that causes increased capillary permeability and is responsible for the pain associated with inflammation. Serotonin and histamine are also mediators of inflammation, but they are not primarily known for increasing capillary permeability or inducing pain. Nitric oxide is involved in various physiological processes but is not a primary mediator of inflammation that causes increased capillary permeability and pain.
Question 3 of 5
A group of prison inmates developed tuberculosis following exposure to an infected inmate. On examination, tissues were soft and granular (like clumped cheese). Which of the following is the most likely cause?
Correct Answer: C
Rationale: The correct answer is C. Caseous necrosis is characteristic of tuberculosis, where the tissue has a soft, cheese-like appearance. Coagulative necrosis involves protein denaturation, liquefactive necrosis is seen in brain infarcts and abscesses, and autonecrosis is not a recognized term in pathology, making them incorrect choices in this scenario.
Question 4 of 5
A hospital patient's complex medical history includes a recent diagnosis of kidney cancer. Which of the following medications is used to treat metastatic kidney cancer?
Correct Answer: B
Rationale: The correct answer is B: Aldesleukin (Proleukin). Aldesleukin is a medication used in the treatment of metastatic kidney cancer. It is a recombinant interleukin-2 that works by stimulating the immune system to attack cancer cells. Choice A, Filgrastim, is a medication used to stimulate the production of white blood cells. Choice C, Interferon alfa-2b, is used in the treatment of certain cancers but not specifically metastatic kidney cancer. Choice D, Darbepoetin alfa, is used to treat anemia by stimulating red blood cell production and is not indicated for metastatic kidney cancer.
Question 5 of 5
A patient is to be administered an immunization. The serum contains aluminum phosphate. What route is most appropriate to administer this immunization?
Correct Answer: A
Rationale: The most appropriate route to administer an immunization containing aluminum phosphate is intramuscularly. Aluminum phosphate is commonly used as an adjuvant in vaccines to enhance the immune response. Intramuscular administration allows for the vaccine to be delivered into the muscle tissue, where it can be effectively absorbed by the body's immune cells. Subcutaneous administration is not ideal for vaccines containing aluminum phosphate, as it may not elicit the desired immune response. Intravenous administration is typically reserved for specific medications or situations that require rapid absorption into the bloodstream. Oral administration is not suitable for vaccines containing aluminum phosphate as they would be degraded in the gastrointestinal tract.
