WGU Pathophysiology Final Exam
1. When teaching a patient about the use of finasteride (Proscar) for benign prostatic hyperplasia (BPH), what should the nurse emphasize about the expected outcomes of this therapy?
- A. Expect improvement in symptoms within a few days.
- B. Improvement in symptoms may take several weeks or months.
- C. Expect immediate improvement in urinary flow.
- D. The medication will cure BPH after treatment is complete.
Correct answer: B
Rationale: The correct answer is B. The effects of finasteride in treating BPH may take several weeks or months to become noticeable as it works by shrinking the prostate gland over time. Therefore, patients should be informed that improvement in symptoms may not be immediate. Choice A is incorrect because improvement in symptoms is not expected within a few days. Choice C is incorrect as immediate improvement in urinary flow is not typical with finasteride. Choice D is incorrect because finasteride manages BPH symptoms but does not cure the condition.
2. When teaching a patient starting on oral contraceptives, what should the nurse include regarding the medication's effectiveness?
- A. Oral contraceptives are 100% effective when taken correctly.
- B. Oral contraceptives are effective immediately after starting.
- C. Oral contraceptives are less effective if taken with certain antibiotics.
- D. Oral contraceptives are less effective if taken with food.
Correct answer: C
Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics as they may interfere with the effectiveness of the contraceptive. It is important for patients to be aware of this interaction to consider additional contraceptive methods during antibiotic therapy. Choices A and B are incorrect as no contraceptive method is 100% effective, and oral contraceptives typically require a period of time to reach full effectiveness. Choice D is incorrect as taking oral contraceptives with food does not significantly impact their effectiveness.
3. A 54-year-old man presents with a temperature of 38.8°C (101.8°F), a racing heart, fatigue, and an upset stomach after spending an afternoon building a deck on a very hot, humid day. The physician assessing the man is performing a differential diagnosis as part of her assessment. Which finding would suggest fever rather than hyperthermia as a cause of the elevation in the man's temperature?
- A. Absence of sweating
- B. Shivering
- C. Lack of thirst
- D. Increased heart rate
Correct answer: B
Rationale: Shivering is a physiological response to fever, as the body attempts to generate heat to increase the internal temperature. Hyperthermia, on the other hand, does not involve shivering. Absence of sweating (choice A) is more indicative of hyperthermia, as the body struggles to cool down without sweating. Lack of thirst (choice C) can be seen in both fever and hyperthermia. Increased heart rate (choice D) can occur in both fever and hyperthermia due to the body's attempt to regulate temperature.
4. A newborn is diagnosed with congenital intrinsic factor deficiency. Which of the following types of anemia will the nurse see documented on the chart?
- A. Iron deficiency anemia
- B. Sideroblastic anemia
- C. Pernicious anemia
- D. Hemolytic anemia
Correct answer: C
Rationale: The correct answer is C, Pernicious anemia. Pernicious anemia is associated with a congenital intrinsic factor deficiency, leading to the impaired absorption of vitamin B12. Iron deficiency anemia (Choice A) is not directly related to intrinsic factor deficiency. Sideroblastic anemia (Choice B) is characterized by defective iron uptake by developing erythrocytes and is not linked to intrinsic factor deficiency. Hemolytic anemia (Choice D) involves the premature destruction of red blood cells and is not specifically associated with intrinsic factor deficiency.
5. A 30-year-old man has a history of heart transplant and is receiving long-term steroids to prevent rejection. The patient is due for routine vaccines. Attenuated vaccines are contraindicated in this patient because the antigen is:
- A. live and can cause infection.
- B. mutated and infectious.
- C. inactive but still infectious
- D. pathogenic
Correct answer: A
Rationale: The correct answer is A: live and can cause infection. Patients who are immunocompromised, like those receiving long-term steroids after an organ transplant, should not receive live vaccines because the live attenuated organisms in these vaccines can cause infections in individuals with weakened immune systems. Choice B is incorrect because attenuated vaccines are live but weakened, not mutated. Choice C is incorrect because while inactive, attenuated vaccines are not infectious. Choice D is incorrect because attenuated vaccines are not pathogenic; they are attenuated (weakened) forms of the pathogen.
