ATI Pathophysiology Final Exam
1. Which of the following is a characteristic of the human immunodeficiency virus (HIV), which causes AIDS?
- A. HIV only infects B cells
- B. HIV is a retrovirus
- C. Infection does not require a host cell receptor
- D. After infection, cell death is immediate
Correct answer: B
Rationale: The correct answer is B. HIV is a retrovirus that infects T cells and leads to the gradual destruction of the immune system. Choice A is incorrect because HIV infects T cells primarily, not just B cells. Choice C is incorrect because HIV infection requires host cell receptors for entry. Choice D is incorrect because cell death after HIV infection is not immediate; instead, the virus gradually weakens the immune system over time.
2. A young man has received a diagnosis of androgen deficiency and has been prescribed testosterone. At clinic follow-up appointments, the nurse should prioritize which of the following assessments?
- A. Bladder ultrasound and urine testing for glucose and ketones
- B. Weight and measurement of blood pressure
- C. Hearing assessment and abdominal girth measurement
- D. Deep tendon reflexes and random blood glucose testing
Correct answer: B
Rationale: In a patient receiving testosterone therapy for androgen deficiency, monitoring weight and blood pressure is crucial. Testosterone therapy can lead to weight gain and hypertension, making regular assessments of these parameters important to detect and manage any adverse effects. Choices A, C, and D are not the priority assessments for a patient on testosterone therapy. Bladder ultrasound and urine testing for glucose and ketones, hearing assessment and abdominal girth measurement, and deep tendon reflexes and random blood glucose testing are not directly related to the common side effects or monitoring requirements of testosterone therapy.
3. Why is a beta-blocker prescribed to a client with a history of myocardial infarction?
- A. To reduce myocardial oxygen demand.
- B. To increase cardiac output.
- C. To prevent arrhythmias.
- D. To prevent the development of angina.
Correct answer: A
Rationale: The primary reason for administering a beta-blocker to a client with a history of myocardial infarction is to reduce myocardial oxygen demand. By reducing myocardial oxygen demand, beta-blockers help decrease the workload on the heart, making it easier for the heart to function effectively. This is crucial for clients with a history of myocardial infarction to prevent further damage to the heart. Choice B is incorrect because beta-blockers do not aim to increase cardiac output; instead, they help improve cardiac function by reducing workload. Choice C is incorrect because while beta-blockers can help prevent certain arrhythmias, the primary reason for their use in this case is to reduce myocardial oxygen demand. Choice D is incorrect as preventing angina is not the primary purpose of administering beta-blockers to a client with a history of myocardial infarction.
4. Which of the following characteristics is common in both malignant and benign tumors?
- A. Uncontrolled cell growth
- B. Rapid growth
- C. Metastasis
- D. Invasion of surrounding tissue
Correct answer: A
Rationale: The correct answer is A: Uncontrolled cell growth. This characteristic is common to both malignant and benign tumors. Benign tumors are non-cancerous growths that do not invade nearby tissue or spread to other parts of the body. Therefore, choices B, C, and D are incorrect. Rapid growth, metastasis, and invasion of surrounding tissue are characteristics typically associated with malignant tumors.
5. A client with a pneumothorax is receiving oxygen therapy. Which assessment finding would indicate that the treatment is effective?
- A. Increased respiratory rate
- B. Decreased oxygen saturation levels
- C. Improved breath sounds on the affected side
- D. Increased dyspnea and chest pain
Correct answer: C
Rationale: In a client with a pneumothorax receiving oxygen therapy, improved breath sounds on the affected side would indicate effective treatment. This finding suggests that the collapsed lung is re-expanding, allowing air to flow more freely in and out of the affected area. Choices A, B, and D are incorrect: Increased respiratory rate, decreased oxygen saturation levels, and increased dyspnea and chest pain are signs of ineffective treatment or worsening of the condition in a client with a pneumothorax.
