ATI Pathophysiology Exam 1

1. A patient is prescribed medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse teach the patient about the proper use of this medication?

A. Take the medication at the same time each day to maintain consistent hormone levels.
B. Avoid prolonged sun exposure while taking this medication.
C. Discontinue the medication if side effects occur.
D. Apply the medication once a week.

Correct answer: A

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Consistency in timing helps regulate the hormone levels in the body, ensuring the medication's optimal benefit. Choice B is incorrect as there is no specific need to avoid sun exposure with this medication. Choice C is incorrect because discontinuing the medication without consulting the healthcare provider may not be safe. Choice D is incorrect as medroxyprogesterone acetate is typically taken orally and not applied topically once a week.

2. What is a common cause of a pulmonary embolism?

A. An autoimmune disorder
B. A venous blood clot from the lower extremity
C. An increase in intracranial pressure
D. Hypotension

Correct answer: B

Rationale: A pulmonary embolism is commonly caused by a blood clot that originates in the venous system of the lower extremity and travels to the lungs, blocking blood flow. This clot is known as a venous thromboembolism. An autoimmune disorder (Choice A) is not typically associated with pulmonary embolism. Intracranial pressure (Choice C) refers to pressure inside the skull and is unrelated to pulmonary embolism. Hypotension (Choice D) is low blood pressure and is not a common cause of pulmonary embolism.

3. A client with diabetes mellitus has just undergone a right, below-the-knee amputation following gangrene infection. A few days after the amputation, the client confides in the nurse that he still feels his right foot. Knowing the pathophysiologic principles behind this, the nurse can:

A. administer a psychotropic medication to help the client cope with the sensation of his amputated leg.
B. explain that many amputees have this sensation and that one theory surmises the end of a regenerating nerve becomes trapped in the scar tissue of the amputation site.
C. call the physician and request an order for a psychological consult.
D. educate the client that this area has an unusually abnormal increase in sensitivity to sensation but that it will go away with time.

Correct answer: B

Rationale: The correct answer is B. The sensation of feeling the amputated limb is known as phantom limb pain, which is common after amputation. One theory suggests that it occurs because the end of a regenerating nerve becomes trapped in the scar tissue at the amputation site. Administering psychotropic medication (choice A) is not the first-line treatment for phantom limb pain. Requesting a psychological consult (choice C) is premature without first addressing the known pathophysiological basis of phantom limb pain. Educating the client that the sensitivity will go away with time (choice D) is not entirely accurate as phantom limb pain can persist long-term.

4. What is the major effect of filgrastim (Neupogen) in a patient with chronic renal failure?

A. Decreases neutropenia related to chemotherapy
B. Decreases white blood cells related to infection
C. Decreases growth of blood vessels due to ischemia
D. Decreases platelet count related to bleeding

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.

5. Cellular swelling is:

A. Irreversible
B. Evident early in all types of cellular injury
C. Manifested by decreased intracellular sodium
D. None of the above is correct

Correct answer: B

Rationale: Cellular swelling is indeed evident early in all types of cellular injury. This occurs due to the influx of water into the cell, leading to swelling. Choice A is incorrect because cellular swelling is reversible if the injury is not severe. Choice C is incorrect because cellular swelling is not manifested by decreased intracellular sodium; in fact, it is associated with increased intracellular sodium due to water influx. Choice D is incorrect as option B is the correct statement.
