Pathophysiology Practice Exam Questions
Question 1 of 5
A patient is taking medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What should the nurse include in the patient teaching?
Correct Answer: C
Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels. This is important for the effectiveness of medroxyprogesterone acetate. Choice A is incorrect because medroxyprogesterone acetate does not need to be taken with food. Choice B is irrelevant as sun exposure is not a concern with this medication. Choice D is incorrect as discontinuing the medication without consulting a healthcare provider can lead to adverse effects.
Question 2 of 5
A report comes back indicating that muscular atrophy has occurred. A nurse recalls that muscular atrophy involves a decrease in muscle cell size:
Correct Answer: B
Rationale: The correct answer is B: Size. Muscular atrophy is characterized by a reduction in the size of muscle cells. This decrease in size can be due to various factors such as disuse, aging, or disease. Choice A, Number, is incorrect because muscular atrophy does not involve a decrease in the number of muscle cells but rather their size. Choice C, Vacuoles, is incorrect as vacuoles are not directly related to the definition of muscular atrophy. Choice D, Lipofuscin, is incorrect as lipofuscin is a pigment associated with aging and has no direct connection to the decrease in muscle cell size seen in muscular atrophy.
Question 3 of 5
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?
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.
Question 4 of 5
A 44-year-old man presents with muscle weakness and fatigue. He states that he has experienced difficulty climbing stairs and even holding his arms up to comb his hair. Which test is most likely to help confirm the diagnosis?
Correct Answer: A
Rationale: The correct answer is Electromyography (EMG). EMG is commonly used to diagnose conditions involving muscle weakness and fatigue, such as myasthenia gravis. Nerve conduction studies primarily assess nerve function rather than muscle involvement. While a muscle biopsy can provide valuable information, EMG is more specific for evaluating muscle function in this context. A blood test for autoantibodies may be helpful in certain autoimmune conditions but is not the primary test for confirming the diagnosis based on the patient's symptoms of muscle weakness and fatigue.
Question 5 of 5
How are antibodies produced?
Correct Answer: A
Rationale: Antibodies are produced by B cells. B cells are specialized white blood cells that generate antibodies as part of the immune response. B cells differentiate into plasma cells that secrete antibodies. T cells play a role in cell-mediated immunity, not antibody production. Helper cells, or helper T cells, assist in activating B cells but do not directly produce antibodies. Memory cells store information about previous infections but do not actively produce antibodies.
