ATI Pathophysiology Exam
1. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What therapeutic effect is expected from this medication?
- A. Reduction in prostate size and improvement in urinary symptoms
- B. Increase in urine flow and relief of urinary obstruction
- C. Improvement in erectile function
- D. Relief of pain associated with BPH
Correct answer: A
Rationale: The correct answer is A: Reduction in prostate size and improvement in urinary symptoms. Finasteride works by reducing the size of the prostate gland, which in turn helps alleviate urinary symptoms such as frequency, urgency, weak stream, and incomplete emptying of the bladder. Choice B is incorrect as while finasteride can improve urine flow indirectly by reducing prostate size, it does not directly increase urine flow. Choice C is incorrect because finasteride is not intended to improve erectile function. Choice D is incorrect as finasteride does not primarily provide relief from pain associated with BPH.
2. A patient has been diagnosed with chronic renal failure. Which of the following agents will assist in raising the patient's hemoglobin levels?
- A. Epoetin alfa (Epogen, Procrit)
- B. Pentoxifylline (Pentoxil)
- C. Estazolam (ProSom)
- D. Dextromethorphan hydrobromide
Correct answer: A
Rationale: The correct answer is A: Epoetin alfa (Epogen, Procrit). Epoetin alfa is a synthetic form of erythropoietin that stimulates red blood cell production and is commonly used to treat anemia in patients with chronic renal failure. By increasing red blood cell production, epoetin alfa helps raise hemoglobin levels in these patients. Pentoxifylline (Choice B) is not indicated for raising hemoglobin levels in chronic renal failure patients; it is a peripheral vasodilator used to improve blood flow. Estazolam (Choice C) is a benzodiazepine used for treating insomnia and has no role in raising hemoglobin levels. Dextromethorphan hydrobromide (Choice D) is a cough suppressant and is not used to raise hemoglobin levels in patients with chronic renal failure.
3. An older adult patient has just sheared the skin on her elbow while attempting to boost herself up in bed, an event that has precipitated acute inflammation in the region surrounding the wound. Which of the following events will occur during the vascular stage of the patient's inflammation?
- A. Outpouring of exudate into interstitial spaces
- B. Chemotaxis
- C. Accumulation of leukocytes along epithelium
- D. Phagocytosis of cellular debris
Correct answer: A
Rationale: During the vascular stage of inflammation, there is an outpouring of exudate into the interstitial spaces, leading to swelling and edema. Choice B, chemotaxis, occurs during the cellular stage of inflammation, where leukocytes move to the site of injury in response to chemical signals. Choice C, accumulation of leukocytes along the epithelium, is not a typical event during the vascular stage. Phagocytosis of cellular debris, as in choice D, mainly occurs during the resolution stage of inflammation.
4. A patient is prescribed finasteride (Proscar) for benign prostatic hyperplasia (BPH). What should the nurse include in the patient teaching regarding the expected outcomes of this therapy?
- A. The medication will cure BPH after treatment is complete.
- B. The effects of the medication may take several weeks or months to become noticeable.
- C. The medication may cause increased hair growth.
- D. The medication may decrease libido.
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, so patients should be informed about this expected time frame. Choice A is incorrect because finasteride does not cure BPH but helps manage symptoms. Choice C is incorrect as increased hair growth is a side effect of finasteride, not an expected outcome for BPH treatment. Choice D is also incorrect as decreased libido is a potential side effect of finasteride, not an expected outcome for BPH treatment.
5. 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.
