Pathophysiology Practice Exam
1. A male patient is concerned about the risk of prostate cancer while receiving finasteride (Proscar) for benign prostatic hyperplasia (BPH). What should the nurse explain about this risk?
- A. Finasteride has been shown to lower the risk of developing prostate cancer.
- B. Finasteride has no effect on the risk of developing prostate cancer.
- C. Finasteride may increase the risk of developing prostate cancer, so regular screening is important.
- D. Finasteride does not affect the risk of prostate cancer, so regular screening is unnecessary.
Correct answer: A
Rationale: The correct answer is A. Finasteride has been shown to lower the risk of developing prostate cancer. Studies have demonstrated that finasteride can reduce the incidence of prostate cancer. However, it is still recommended to have regular screening to monitor for any potential issues. Choice B is incorrect as finasteride has shown to have a positive effect on reducing prostate cancer risk. Choice C is inaccurate because finasteride decreases, not increases, the risk of prostate cancer. Choice D is incorrect as regular screening is still necessary despite the risk reduction associated with finasteride.
2. A 21-year-old male is brought to the ED following a night of partying in his fraternity. His friends found him 'asleep' and couldn't get him to respond. They cannot recall how many alcoholic beverages he drank the night before. While educating a student nurse and the man's friends, the nurse begins by explaining that alcohol is:
- A. A water-soluble compound that is easily absorbed by the gastric lining of the stomach.
- B. Very lipid-soluble and rapidly crosses the blood–brain barrier.
- C. Able to reverse the transport of some substances to remove them from the brain.
- D. Very likely to cause sedation and therefore the client just needs to sleep it off.
Correct answer: B
Rationale: The correct answer is B. Alcohol is very lipid-soluble and rapidly crosses the blood–brain barrier, leading to its effects on the central nervous system and causing symptoms like sedation and unconsciousness. Choice A is incorrect because alcohol is not water-soluble; it is lipid-soluble. Choice C is incorrect as alcohol does not reverse the transport of substances from the brain. Choice D is incorrect as sedation from alcohol is not a reason to just 'sleep it off' in cases of alcohol poisoning, which can be life-threatening and requires medical attention.
3. In clients with a cognitive impairment disorder, the phenomenon of increased confusion in the early evening hours is called:
- A. Aphasia.
- B. Agnosia.
- C. Sundowning.
- D. Confabulation.
Correct answer: C
Rationale: The correct answer is C: Sundowning. Sundowning is a phenomenon where individuals with cognitive impairment experience increased confusion and agitation in the late afternoon or early evening. This often occurs in conditions like dementia. Choice A, Aphasia, refers to a language disorder affecting a person's ability to communicate. Choice B, Agnosia, is the inability to recognize objects. Choice D, Confabulation, is the production of false memories without the intention to deceive, often seen in conditions like Korsakoff's syndrome.
4. A nurse caring for a patient with a diagnosis of lung cancer is aware that the primary risk factor for developing lung cancer is:
- A. Alcohol consumption
- B. Smoking
- C. Poor diet
- D. Environmental exposure
Correct answer: B
Rationale: The correct answer is B: Smoking. Smoking is the primary risk factor for developing lung cancer. Tobacco smoke contains numerous carcinogens that can damage the cells in the lungs, leading to the development of cancer. Alcohol consumption (Choice A), poor diet (Choice C), and environmental exposure (Choice D) can contribute to overall health risks, but they are not the primary risk factors specifically associated with the development of lung cancer.
5. What causes type I diabetes?
- A. Overproduction of insulin from the beta cells of the pancreas
- B. Destruction of the beta cells within the pancreas, resulting in an inability to produce insulin
- C. Loss of insulin receptors on the target cells, resulting in insulin resistance
- D. A pituitary tumor in the brain, resulting in increased antidiuretic hormone production
Correct answer: B
Rationale: Type I diabetes is caused by the destruction of the beta cells in the pancreas, leading to an inability to produce insulin. This results in a lack of insulin, leading to hyperglycemia. Choice A is incorrect as type I diabetes is characterized by a deficiency of insulin production, not overproduction. Choice C describes the pathophysiology of type 2 diabetes, where insulin receptors become less responsive to insulin. Choice D is unrelated to type I diabetes as it describes a pituitary tumor causing increased antidiuretic hormone production.
