WGU Pathophysiology Final Exam
1. A patient with a history of breast cancer is being prescribed tamoxifen (Nolvadex). The nurse should educate the patient about what potential side effect of this medication?
- A. Increased risk of venous thromboembolism
- B. Increased risk of hot flashes
- C. Increased risk of cataracts
- D. Increased risk of bone fractures
Correct answer: A
Rationale: The correct answer is A: Increased risk of venous thromboembolism. Tamoxifen is known to increase the risk of venous thromboembolism, a serious side effect. Patients should be educated about the signs and symptoms of blood clots such as swelling, redness, warmth, or pain in the affected limb. Choices B, C, and D are incorrect because tamoxifen is not associated with an increased risk of hot flashes, cataracts, or bone fractures.
2. Prior to leaving on a backpacking trip to Southeast Asia, a college student has received a tetanus booster shot. This immunization confers protection by way of what immune process?
- A. Passive natural immunity
- B. Active natural immunity
- C. Passive artificial immunity
- D. Active artificial immunity
Correct answer: D
Rationale: The correct answer is D: Active artificial immunity. A tetanus booster shot confers protection through active artificial immunity. Active immunity involves the body producing its antibodies in response to an antigen, providing long-lasting protection. In this case, the tetanus booster shot triggers the student's immune system to produce specific antibodies against tetanus toxins. Choices A, B, and C are incorrect because passive immunity does not involve the individual's immune system producing antibodies; instead, it involves the direct transfer of antibodies from another source (natural or artificial) for immediate, but temporary, protection.
3. A nurse is providing discharge teaching to a patient who will be taking sildenafil (Viagra). Which of the following should the nurse include in the instructions?
- A. Take this medication 1 hour before sexual activity.
- B. Do not take more than one dose in a 24-hour period.
- C. Seek immediate medical attention if you experience vision or hearing loss.
- D. Take this medication on an empty stomach.
Correct answer: B
Rationale: The correct answer is B: 'Do not take more than one dose in a 24-hour period.' It is essential for the nurse to emphasize this instruction to prevent potential adverse effects from taking multiple doses of sildenafil. Choice A is incorrect because sildenafil should be taken approximately 30 minutes to 4 hours before sexual activity, not specifically 1 hour before. Choice C is important but not the priority; while vision or hearing loss are potential serious side effects of sildenafil, the immediate concern should be focused on dose frequency. Choice D is incorrect as sildenafil can be taken with or without food.
4. A nurse practitioner is assessing a 7-year-old boy who has been brought to the clinic by his mother, who is concerned about her son's increasingly frequent, severe headaches. Which of the nurse's questions is least likely to yield data that will confirm or rule out migraines as the cause of his problem?
- A. Does your son experience nausea or vomiting when he has a headache?
- B. Does your son have a history of recent head injury?
- C. Does your son become sensitive to light when he has a headache?
- D. Does anyone in your family have a history of migraines?
Correct answer: B
Rationale: Asking about a history of recent head injury is less likely to yield data relevant to confirming or ruling out migraines. Migraines are often associated with symptoms like nausea, vomiting, sensitivity to light, and a family history of migraines. While head injuries can cause headaches, the focus of the assessment in this case should be on symptoms more specific to migraines to guide the diagnosis and management.
5. A client has been admitted to the hospital with symptoms of Guillain-Barré syndrome. Which aspect of the client's condition would require priority monitoring?
- A. Monitoring oxygen saturation levels
- B. Monitoring for signs of respiratory compromise
- C. Monitoring for changes in consciousness
- D. Monitoring blood pressure closely
Correct answer: B
Rationale: In Guillain-Barré syndrome, respiratory muscle weakness can lead to respiratory compromise, making it crucial to prioritize monitoring for signs of respiratory distress. Monitoring oxygen saturation levels is important but is secondary to assessing for respiratory compromise in this condition. Changes in consciousness and monitoring blood pressure closely are not typically the priority in Guillain-Barré syndrome.
