ATI Pathophysiology Exam 2
1. A patient has acute respiratory failure (ARF). Which of the following would the nurse expect to find?
- A. Alkalosis and hyperventilation
- B. Hypoxemia and hypercapnia
- C. Alkalosis and high potassium
- D. Elevated sodium and acidosis
Correct answer: B
Rationale: In acute respiratory failure, hypoxemia (low blood oxygen) and hypercapnia (high blood carbon dioxide) are commonly observed. Choice A is incorrect because alkalosis (high pH) and hyperventilation are not typically seen in acute respiratory failure. Choice C is incorrect as it mentions alkalosis and high potassium, which are not characteristic of acute respiratory failure. Choice D is also incorrect because elevated sodium and acidosis are not typically associated with acute respiratory failure.
2. A patient is prescribed clomiphene citrate (Clomid) for the treatment of infertility. Which of the following statements should be included in the nurse's teaching?
- A. This drug induces ovulation by stimulating gonadotropins.
- B. This drug induces ovulation by inhibiting gonadotropins.
- C. This drug suppresses ovulation by inhibiting gonadotropins.
- D. This drug increases progesterone levels, which maintains pregnancy.
Correct answer: A
Rationale: The correct statement to include in the nurse's teaching is that clomiphene induces ovulation by stimulating the release of gonadotropins, which in turn stimulate the ovaries. Choice B is incorrect because clomiphene does not induce ovulation by inhibiting gonadotropins. Choice C is also incorrect as clomiphene does not suppress ovulation by inhibiting gonadotropins. Choice D is inaccurate as clomiphene does not directly increase progesterone levels to maintain pregnancy.
3. A patient is being treated for active tuberculosis with ethambutol (Myambutol). The patient states to the nurse that he cannot identify the red and green on the traffic lights when he is driving. Based on this finding, what medical intervention is most appropriate?
- A. Assess for photosensitivity.
- B. Discontinue ethambutol (Myambutol).
- C. Decrease the ethambutol (Myambutol) dose.
- D. Administer vitamin B.
Correct answer: A
Rationale: The correct answer is to assess for photosensitivity. Ethambutol can cause optic neuritis, leading to visual disturbances, including difficulty differentiating red and green colors. This is a sign of optic nerve damage and requires immediate evaluation. Discontinuing ethambutol may be necessary if optic neuritis is confirmed, but this decision should be made by a healthcare provider. Decreasing the dose of ethambutol may not address the visual changes. Administering vitamin B does not directly address the side effect caused by ethambutol.
4. When a client has their 'fight or flight' system activated, which below is a manifestation of that?
- A. Decreased blood pressure
- B. Decreased heart rate
- C. Decreased respiration rate
- D. Increased glucose levels
Correct answer: D
Rationale: The correct answer is D, 'Increased glucose levels.' When the 'fight or flight' system is activated, the body releases glucose to provide energy for the impending response. This increase in glucose levels helps fuel the body's reaction to the perceived threat or stressor. Choices A, B, and C are incorrect because during the 'fight or flight' response, blood pressure, heart rate, and respiration rate typically increase to prepare the body to confront or flee from the perceived danger.
5. Identify which conditions are due to excessive immune response.
- A. Allergies and onychomycosis
- B. Type II diabetes and smallpox
- C. Chronic renal failure and macular degeneration
- D. Allergies and rheumatoid arthritis
Correct answer: D
Rationale: The correct answer is D: Allergies and rheumatoid arthritis. Allergies are caused by an excessive immune response to harmless substances, while rheumatoid arthritis is an autoimmune disorder where the immune system attacks the body's tissues, leading to inflammation and joint damage. Choices A, B, and C are incorrect. Onychomycosis is a fungal infection of the nails, Type II diabetes is a metabolic disorder not primarily related to immune response, smallpox is a viral infection, chronic renal failure is a kidney condition, and macular degeneration is an eye disorder, none of which are directly linked to excessive immune response.
