Pathophysiology Final Exam
1. When educating a patient starting on oral contraceptives, what should the nurse include in the teaching plan regarding potential side effects?
- A. Weight gain, mood changes, and nausea
- B. Increased appetite, insomnia, and fatigue
- C. Breast tenderness, headaches, and dizziness
- D. Fatigue, hair loss, and joint pain
Correct answer: A
Rationale: The correct answer is A: Weight gain, mood changes, and nausea are common side effects of oral contraceptives. Weight gain may occur due to fluid retention or changes in metabolism. Mood changes can be caused by hormonal fluctuations. Nausea is a common side effect that usually improves after a few months of use. Choices B, C, and D are incorrect because they do not reflect common side effects associated with oral contraceptives. Increased appetite, insomnia, breast tenderness, headaches, dizziness, fatigue, hair loss, and joint pain are not typically reported side effects of oral contraceptives.
2. Which type of lymphocyte recognizes and eliminates virus-infected cells and cancerous cells?
- A. Neutrophils
- B. Macrophages
- C. Natural killer cells
- D. Langerhans cells
Correct answer: C
Rationale: Natural killer cells are a type of lymphocyte that plays a crucial role in recognizing and eliminating virus-infected cells and cancerous cells. Neutrophils (Choice A) are a type of white blood cell involved in fighting infections, mainly through phagocytosis. Macrophages (Choice B) are another type of white blood cell that engulfs and digests cellular debris and pathogens. Langerhans cells (Choice D) are a type of dendritic cell found in the skin and mucosa, primarily involved in antigen presentation.
3. A 45-year-old diabetic male is experiencing erectile dysfunction. If his erectile dysfunction is caused by the nervous system, then the nurse can educate the client that the venous blood supply to the penis is controlled by:
- A. Sympathetic nerves.
- B. Parasympathetic nerves.
- C. Somatic nerves.
- D. Spinal reflexes.
Correct answer: B
Rationale: Erectile function is primarily controlled by the parasympathetic nervous system, which facilitates the dilation of blood vessels in the penis. The parasympathetic nerves are responsible for vasodilation in the penis, allowing blood to enter and creating an erection. Sympathetic nerves, on the other hand, are responsible for ejaculation by causing contraction of the muscles around the vas deferens. Somatic nerves are involved in sensation and movement, not specifically in controlling blood supply to the penis. Spinal reflexes can play a role in the erectile process, but they are not directly responsible for controlling the venous blood supply.
4. A patient is prescribed estradiol (Estrace) for hormone replacement therapy (HRT). What should the nurse monitor during this therapy?
- A. Blood glucose levels
- B. Liver function tests
- C. Kidney function tests
- D. Blood pressure
Correct answer: B
Rationale: During estradiol therapy, monitoring liver function tests is essential due to the potential for liver dysfunction. Estradiol can affect liver function, making it crucial to monitor enzyme levels. Choice A, blood glucose levels, is not directly impacted by estradiol therapy, making it an incorrect choice. Choice C, kidney function tests, is not typically affected by estradiol therapy, so it is not the priority for monitoring. Choice D, blood pressure, is also not the primary parameter to monitor during estradiol therapy unless there are pre-existing conditions that warrant such monitoring.
5. A tension pneumothorax requires a needle thoracostomy and/or chest tube placement as treatment to which component of the pathophysiology of the condition?
- A. An accumulation of blood in the pleural space, which makes it difficult for the lungs to exchange gases.
- B. Extreme pain caused by a fractured rib
- C. A large accumulation of trapped air in the pleural space affecting both the lungs and heart.
- D. Sudden failure of the respiratory system due to fluid accumulation in the alveoli
Correct answer: C
Rationale: A tension pneumothorax is characterized by a large accumulation of trapped air in the pleural space, creating pressure that affects both the lungs and heart. This condition can lead to life-threatening consequences by shifting mediastinal structures and impairing cardiac function. Treatment involves decompressing the trapped air to relieve the tension. Choices A, B, and D are incorrect as they do not describe the primary pathophysiological mechanism of tension pneumothorax, which is the accumulation of air in the pleural space, not blood, rib fractures, or alveolar fluid accumulation.
