PATHO 370 Final Exam: Practice Questions& Answers: Updated Guide

PATH O 370 Final Exam Practice Questions The cellular response indicative of injury due to faulty metabolism is Hydropic swelling Lactate production Metaplasia Intracellular accumulations (Ans- intracellular accumulation After surgery to remove a lung tumor, your patient is scheduled for chemotherapy, which will Selectively kill tumor cells Stimulate immune cells to fight the cancer Have minimal side effects Kill rapidly dividing cells (Ans- kill rapidly dividing cells All these cellular responses are potentially reversible except Necrosis Metaplasia Atrophy Hyperplasia (Ans- Necrosis A 17-year-old college -bound student receives a vaccine against an organism that causes meningitis. This is an example of Primary prevention Secondary prevention Tertiary prevention Disease treatment (Ans- primary prevention Which is not normally secreted in response to stress? Norepinephrine Cortisol Epinephrine Insulin (Ans- insulin A disease that is native to a particular region is called Epidemic Endemic Pandemic Ethnographic (Ans- Endemic Cancer grading is based on Tumor size Local invasion Cell differentiation Metastasis (Ans- cell differentiation Your patient is scheduled for a staging procedure. She wants to know what that means. The correct response is which of the following? It is a procedure for determining the extent of tumor spread It is a histologic examination of tissues to determine the degree of tumor differentiation Is based on exploratory surgery It is biochemical testing of tumor cells to determine the genetic basis of the tumor (Ans- It is a procedure for determining the extent of tumor spread The stage during which the patient functions normally, although the disease processes are well established, is referred to as Latent Subclinical Prodromal Convalescence (Ans- subclinical After bronchoscopy and histologic examination of a suspected tumor, your patient is diagnosed with primary bronchial carcinoma. Thus, the tumor Is benign Is malignant Is secondary to cancer elsewhere in the body Has spread (Ans- Is malignant Tumor markers (Select all that apply.) a. are found only in the blood. b. are produced by normal cells. c. help determine cancer origin. d. help identify progression of cancer. e. include prostatic -specific antigen. (Ans- B, C, D, E Tumor markers are substances associated with tumor cells that may be helpful in identifying their tissue of origin and progression and proliferation of cancer cells. Most tumor markers are not very specific for cancer since normal cells in the tissue of origin also produce them. Tumo r markers include prostatic -specific antigen. Some tumor cell markers are released into the circulation, but others must be identified through biopsy of metastatic tissue. Deficits in immune system function occur in cancer as a result of (Select all that apply.) a. chemotherapy. b. cancer cells. c. cancer metastasis to bone marrow. d. immunotherapy. e. malnutrition. (Ans- A, B, C, E Cancer cells secrete substances that suppress the immune system. Bone marrow suppression may be because of invasion of blood -forming cells in the bone marrow, poor nutrition, and chemotherapeutic agents. By contrast, immunotherapy is a method of harnessing the immune system in the treatment of cancer. The cellular change that is considered preneoplastic is Anaplasia Dysplasia Metaplasia Hyperplasia (Ans- dysplasia Apoptosis is the process of Atrophy Death Proliferation Mutation (Ans- Death After suffering a heart attack, a middle aged man is counseled to take a cholesterol lowering medication. This is an example of Primary prevention
