Final Exam Pathophysiology
1. A patient who is being administered isoniazid (INH) for tuberculosis has a yellow color in the sclera of her eye. What other finding would lead you to believe that hepatotoxicity has developed?
- A. Diarrhea
- B. Numbness
- C. Diminished vision
- D. Light-colored stools
Correct answer: A
Rationale: The correct answer is A: Diarrhea. Hepatotoxicity caused by isoniazid can present with various symptoms, including yellow discoloration of the sclera of the eyes, which indicates jaundice. Another common sign of hepatotoxicity is gastrointestinal symptoms such as nausea, vomiting, and diarrhea, which can occur due to liver dysfunction affecting bile production and digestion. Numbness (choice B) is more commonly associated with peripheral neuropathy caused by isoniazid, while diminished vision (choice C) and light-colored stools (choice D) are not typical manifestations of hepatotoxicity.
2. After studying about fungi, which information indicates a correct understanding of fungi? Fungi causing deep or systemic infections:
- A. Are easily treated with penicillin
- B. Are extremely rare
- C. Never occur with other infections
- D. Are commonly opportunistic
Correct answer: D
Rationale: The correct answer is D: 'Are commonly opportunistic.' Fungi causing deep or systemic infections are commonly opportunistic, particularly in individuals with compromised immune systems. Choice A is incorrect because fungi infections are not easily treated with penicillin. Choice B is incorrect as deep or systemic fungal infections are not extremely rare. Choice C is incorrect as fungal infections can co-occur with other infections.
3. 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.
4. Which of the following is a clinical manifestation of hyperthyroidism?
- A. Tachycardia
- B. Constipation
- C. Weight gain
- D. Fatigue
Correct answer: A
Rationale: The correct answer is A: Tachycardia. Tachycardia, which is an increased heart rate, is a classic clinical manifestation of hyperthyroidism. In hyperthyroidism, there is an excess production of thyroid hormones, leading to an increased metabolic rate. This increased metabolism can cause symptoms such as a rapid heart rate. Choices B, C, and D are incorrect because constipation, weight gain, and fatigue are more commonly associated with hypothyroidism, where there is a deficiency of thyroid hormones leading to a slower metabolic rate.
5. When caring for a patient with systemic lupus erythematosus (SLE), the disease the nurse is dealing with is an example of:
- A. Autoimmunity
- B. Alloimmunity
- C. Homoimmunity
- D. Alleimmunity
Correct answer: A
Rationale: When a nurse cares for a patient with systemic lupus erythematosus (SLE), the nurse is dealing with an autoimmune disease. In autoimmune diseases like SLE, the immune system mistakenly attacks the body's own tissues. Choice A, 'Autoimmunity,' is the correct answer because SLE is an example of the immune system attacking self-antigens, leading to tissue damage and inflammation. Choices B, C, and D are incorrect. Alloimmunity refers to the immune response against foreign antigens from members of the same species, homoimmunity is not a recognized term in immunology, and alleimmunity is not a valid term in this context.
