ATI Pathophysiology Exam 1

1. Which of the following might result from severe diarrhea?

A. Respiratory acidosis
B. Metabolic alkalosis
C. Respiratory alkalosis
D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is D: Metabolic acidosis. Severe diarrhea can lead to metabolic acidosis because the loss of bicarbonate ions in the stool results in an overall decrease in the body's bicarbonate levels. Respiratory acidosis (choice A) is caused by retention of carbon dioxide, usually due to inadequate alveolar ventilation. Metabolic alkalosis (choice B) is characterized by elevated pH and bicarbonate levels, usually caused by conditions like vomiting. Respiratory alkalosis (choice C) is a condition of low blood carbon dioxide levels and high pH, often due to hyperventilation.

2. Which of the following are manifestations of Cushing syndrome?

A. Truncal obesity with thin extremities.
B. Enlargement of face, hands, and feet.
C. Cachexia.
D. Thick scalp hair.

Correct answer: A

Rationale: Truncal obesity with thin extremities is a classic manifestation of Cushing syndrome due to the redistribution of fat. Enlargement of face, hands, and feet is seen in conditions like acromegaly, not Cushing syndrome. Cachexia is a state of severe weight loss and muscle wasting, typically seen in conditions like cancer or advanced infections. Thick scalp hair is not typically associated with Cushing syndrome.

3. The registered nurse is teaching a class on inflammation and explains that which cell is the predominant phagocyte arriving early at inflammatory and infection sites?

A. Macrophages
B. Mast cells
C. Monocytes
D. Neutrophils

Correct answer: D

Rationale: Neutrophils are the correct answer as they are the predominant phagocytes arriving early at inflammatory and infection sites. Neutrophils are part of the body's innate immune system and are among the first responders to sites of inflammation or infection. They play a crucial role in engulfing and destroying pathogens. Macrophages, although important phagocytes, usually arrive later at the site. Mast cells are involved in allergic reactions and not primarily phagocytes. Monocytes are precursors to macrophages and are not the predominant phagocytes arriving early at inflammatory sites.

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

A. Medroxyprogesterone should be taken with food to prevent nausea.
B. Medroxyprogesterone can be taken intermittently when symptoms worsen.
C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
D. Medroxyprogesterone should be discontinued if side effects occur.

Correct answer: C

Rationale: The correct answer is C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels and effectiveness. Taking it at different times can lead to hormonal fluctuations and reduced medication efficacy. Choice A is incorrect because medroxyprogesterone does not need to be taken with food to prevent nausea. Choice B is incorrect as medroxyprogesterone is typically taken continuously rather than intermittently. Choice D is incorrect because side effects should be reported to the healthcare provider for further evaluation and management, not automatically leading to discontinuation of the medication.

5. Which of the following is a complication of compartment syndrome?

A. Hemorrhage
B. Pain and tissue damage
C. Increased limb function
D. Chronic kidney disease

Correct answer: B

Rationale: The correct answer is B: Pain and tissue damage. Compartment syndrome occurs due to increased pressure within the muscle compartments, leading to pain and tissue damage. Hemorrhage (choice A) is not a typical complication of compartment syndrome. Increased limb function (choice C) is not a complication but rather a potential improvement if the condition is managed appropriately. Chronic kidney disease (choice D) is unrelated to compartment syndrome.
