Republic of the Philippines UNIVERSITY OF NORTHERN PHILIPPINES GRADUATE SCHOOL Vigan City MASTER OF ARTS IN NURSING Final Examination ADVANCE PATHOPHYSIOLOGY 1. Describe the contributions of the early Greek, Italian, and English scholars to the understanding of anatomy, physiology, and pathology. a. Early Greeks Avicenna was a Persian physician who adopted many of the Galenic teachings and expanded on them in his Canon on Medicine, an authoritative work on anatomy. (Siddiquey, Ak Shamsuddin Husain (2009). Para 8) The most famous and influential of the philosopher-scientists of the Islamic world. He was particularly noted for his contributions in the fields of Aristotelian philosophy andmedicine. He composed the Kitāb al-shifāʾ (Book of the Cure), a vast philosophical and scientific encyclopaedia, and Al-Qanun fi al-Tibb (The Canon of Medicine), which is among the most famous books in the history of medicine.

Italian anatomist and founder of pathological anatomy, born in Forlì, and educated at the University of Bologna. Morgagni was appointed professor of anatomy at the University of Padua in 1715. He correlated numerous postmortem examinations with case histories to discover the relationships between diseases and the physical changes in organs. He was particularly accurate in his descriptions of the effects of disease on the heart, lungs, and liver. According to Ventura A. (2000) clinical pathologic conference, we attempt to make a diagnosis fmm a clinical history and our conclusions are confirmed or denied by the pathologist’s report of the autopsy, operation, or biopsy,we are reproducing the pages of the De Sedibus. The use of the clinical pathologic conference is and will be one of the most useful methods to teach medicine. This may be Giovanni Battista Morgagni’s indelible legacy to medicine.

English scholar Florence nighthingale In March 1854 the Crimean War broke out and the reports of the sufferings of the sick and wounded in the English camps created anger in Britain. William Russell, The Times’ correspondent, described the terrible neglect of the wounded, and pointed to the differences between the facilities provided for British and French soldiers. He asked: ‘Are there no devoted women among us, able and willing to go forth to minister to the sick and suffering soldiers of the East in the hospitals of Scutari. Are none of the daughters of England, at this extreme hour of need, ready for such a work of mercy. Must we fall so far below the French in self-sacrifice and devotedness?’ (The Times, 15 and 22 September 1854). Source: Contemporary period ( 30 Sept 2011).

The leg had been encased in a cast, which was just removed. The patient is amazed at the degree to which the muscles in his leg have shrunk. a. Would you consider the changes in the patient’s muscles to be a normal adaptive response? Explain. I wound consider the changes in the patient’s muscles to be a normal adaptive response. According to Handbook of Pathophysiology (2001) Atrophy is a reduction in the size of a cell or organ that may occur when cells face reduced workload or disuse, insufficient blood flow, malnutrition, or reduced hormonal and nerve stimulation. Source: Handbook of Pathophysiology (January 15, 2001): by Springhouse Corporation, With 13 Contributors, Springhouse b. Will these changes have an immediate or long-term effect on the function of the leg? There is a long-term effect on the function of the leg since our patient was encased in a cast the patient need to have therapy, regular exercise and full recovery. 3. People who have had a heart attack may experience additional damage once blood flow has been restored, a phenomenon referred to reperfusion injury. a. What is the proposed mechanism underlying reperfusion injury? According to Rubin, E. et al (2014) Ischemia/reperfusion injury is a common clinical problem that arises in occlusive cardiovascular disease, infection,shock and many other settings. I/R injury reflects the interplay of transient ischemia, consequent tissue damage and exposure of damaged tissue to the oxygen that arrives when blood flow is reestablished (reperfusion). Initially, ischemic cellular damage leads to the generation of free-radical species. Reperfusion then provides abundant molecular O 2 to combine with free radicals to form ROS.(p11) Source: Emanuel Rubin, Howard M. Reisner, Essentials of Rubin’s pathology 6th edition : Lippincott Williams & Wilkins:2007 b. What factors might influence this mechanism? cardiovascular disease infection shock (Rubin, E. (2007) p11) Source: Emanuel Rubin, Howard M. Reisner, Essentials of Rubin’s pathology 6th edition : Lippincott Williams & Wilkins:2007 4. Every day, blood cells in our body become senescent and die without producing signs of inflammation, and yet, massive injury or destruction of tissue, such as occurs with a heart attack, produces significant signs of inflammation. Explain According to Rubin, E. et al (2014) Apoptosis is a prearranged pathway of cell death triggered by a variety of specific extracellular and intracellular signals. It is part of the balance between the life and death of cells and determines that a cell dies when it is no longer useful or when it may be harmful to the larger organism. As a self-defense mechanism, cells that are infected with pathogens or in which genomical terations have occurred are destroyed. In this context, many pathogens have evolved mechanisms to inactivate key components of the apoptotic signaling cascades. Apoptosis detects and destroys many cells that harbor dangerous mutations, thereby maintaining genetic consistency and preventing the development of cancer. By contrast, as in the case of acquired antibiotic resistance in infectious agents, successful clones of tumor cells often devise mechanisms to circumvent apoptosis.

A 23-year-old woman with sickle cell anemia and her husband want to have a child but worry that their child will be born with the disease. a. What is the mother’s genotype in terms of the sickle cell gene? Is she heterozygous or homozygous? The mother is Homozygous. b. If the father is found to have no sickle cell gene, what is the probability of their child having the disease or being a carrier of the disease? According to Smeltzer , Suzzane C (1996) Their child will be a carrier of sickled cell disease. (Smeltzer , Suzzane C (1996) pp124 ) c. If both the mother and father are found to be heterozygous (carriers) of the sickle cell gene, what are the chances that their child would have sickle cell disease or be a carrier of the trait? According to Smeltzer , Suzzane C (1996) In diseases associated with altered recessive genes, both parents- although disease-free themselves carry one normal allele and one altered allele. Each child has one chance in four of inheriting two normal alleles; and two chances in four of inheriting one normal and one altered allele, and therefore being a carrier like both parents.

A 26-year-old woman is planning to become pregnant. a. What information would you give her regarding the effects of medications and drugs on the fetus? What stage of fetal development is associated with greatest risk? According to Pilliteri, A. (2007) Pregnant women takes medications and drugs, prescribed or over the counter should be ask in order to know the effect on a growing fetus even the innocent medications and drugs, for instance isotretinoin (Accutane), a vitamin A preparation taken for acne is associated with spontaneous miscarriage and congenital anomalies. And also herbal supplements should be avaluated carefully before being taken by pregnant women to be certain they don’t stimulate uterine contractions. And First trimester where in organogenesis work out. (Pillitteri, 2007 pp. 249) b. What is the rationale for ensuring that she has an adequate intake of folic acid before conception and during pregnancy? According to Pilliteri, A. (2007) Folic acid, also known as folate or folacin, is a B vitamin needed for forming new body cells. Folate occurs naturally in foods; folic acid is the form produced synthetically for supplements. (Pillitteri, 2007 pp. 231) Not great enough the intake of folic acid Adequate intake of folic acid Megalohemoglobinemia Increase neural tube disorders in fetus Low Birth weight Spina bifida; anencephaly(Pillitteri, 2007 pp. 231) Source: Pillitteri, Adelle Maternal and Child Health Nursing: Care of the Childbearing and Childrearing Family 5th edition: Lippincott Williams & Wilkins, 2007 c. She and her husband have an indoor cat. What precautions should she use in caring for the cat? Removing a cat from the home during pregnancy as a mean of prevention is not necessary as long as the cat is healthy. But taking a new cat is unwise Not to change a cat litter box Not to work in soil area where cats may defecate.

A 30-year-old woman has experienced heavy menstrual bleeding and is told she has a uterine tumor called a leiomyoma. She is worried that this means she has cancer. a. What is the difference between a leiomyoma and a leiomyosarcoma? Leiomyoma Leiomyosarcoma Benign tumor of smooth muscle origin Malignancy of smooth muscle origin Colloquially Soft, shows areas of necrosis on gross known as a “myoma” or “fibroid examination, has irregular borders (invasion into neighboring myometrium) Does not bulge above the surface when cut. 75% of women over 50 years and above 30 years of age. Rare before age 20, and most regress after menopause Monoclonal, range from 1 mm to more 10 to 15 cm vs. 3 to 5 cm than 30 cm in diameter Mitotically Mitotic activity, active leiomyomas show brisk mitotic activity cellular atypia and geographical necrosis are the but are small and sharply demarcated from the best diagnostic criteria. adjacent normal myometrium, and they lack both geographical necrosis and significant cellular atypia. Estrogen promotes their Usually fatal despite combinations of growth, although it does not initiate them. surgery, radiation therapy and chemotherapy. (Rubin, E. (2007), pp.515-516) Source: Emanuel Rubin, Howard M. Reisner, Essentials of Rubin’s pathology 6th edition : Lippincott Williams & Wilkins:2007 b. How would you go about explaining the difference to her? By stating that Leiomyoma is benign or noncancerous they don’t have the ability to metastasize on the other parts of the body and they usually shrink after menopause. And when signs and symptoms occurs, leiomyoma must be removed by myomectomy or hysterectomy and there is less chances to recurs. While in leiomyosarcoma it is cancerous and have the added property of invading contiguous tissues and metastasizing to distant sites, where subpopulations of malignant cells take up residence, grow anew and again invade and there is more chances to recurs. 8. A 32-year-old woman has been told that the report of her annual Pap test revealed the presence of mild dysplasia. a. What questions should this woman ask as a means of becoming informed about the significance of these findings? What is cervical mild dysplasia? Is it fatal or life threatening? If I am having a mild dysplasia, is there a possibility that I will have the cervical cancer? What are the causes of cervical mild dysplasia? What are the treatments of cervical dysplasia? Is it effective? How frequent should I have my pap smear? Is pap smear expensive? b. In obtaining additional information about the results of her Pap test, the woman is informed that dysplastic changes are consistent with CIN 1 classification . i. Does this mean that the woman has cervical cancer? The woman has no cervical cancer. According to an article Pap Smear (2009) CIN 1 is a noncancerous condition of abnormal cell growth and often mild dysplasia disappear without treatment.

Cervical cancer is often reffered to as a sexually transmitted disease. Explain. According to an article “Cervical Cancer.” (2009) Studies indicate that women increase their chances of HPV infection by having intercourse at an early age, by having many sex partners, or by having male partners who have multiple sexual partners.

Her physical exam reveals an obese woman with hirsutism. The physician tells the woman that she might have a condition known as polycystic ovary disease and that further laboratory tests are indicated. a. Among tests ordered are a fasting blood glucose, LH, FSH, and dehydroepiandrosterone levels. What information can these tests provide that would help in establishing a diagnosis of polycystic ovarian syndrome? TEST FBS INFORMATION Evaluate and determine the risk of developing cardiac disease and diabetes. .(Hurst, M. (2008) p463) LH and FSH Determine the level of LH and FSH. If there is increase secretion of LH the follicle will burst and spew the egg out into the peritoneal cavity, where the fingers on the fallopian tube pull the egg into the tube to await fertilization.(Hurst, M.

(2008) p644) Source: Hurst, Marlene HurstReview Pathophysiology: Mc Graw Hill :2008 b. What is the probable cause of this woman’s amenorrhea, hirsutism, and failure to become pregnant? Probable Cause Why Amenorrhea Due to hormonal imbalance, beginning with inappropriate gonadotropin secretion that triggers all the other imbalances, resulting in follicles that never mature or produce viable ova. (Hurst, M. (2008) p644) Hirsutism Excessive levels of circulating androgen. (Hurst, M. (2008) p644) Failure to become pregnant There is no dominant follicle ever matures, ruptures or releases an egg. The causes are lack of GnRH and abnormalities in ovarian and adrenal hormones. Insulin has a role in survival of follicles that should have disintegrated. (Hurst, M.

A 35-year-old woman presents with vulvar pruritus, dysuria, dyspareunia, and an odorless, thick, cheese-like vaginal discharge. She has diabetes mellitus and has recently recovered from a respiratory tract infection, which required antibiotic treatment. a. Given that these manifestations are consistent with Candida infection, what tests might be used to confirm the diagnosis? Diagnosis is made by microscopic identification of spores and hyphae on a glass slide prepared from discharge specimen mixed with potassium hydroxide.( Suzzane C. et el (1996) p1674) Source: Smeltzer , Suzzane C …[et al.] Brunner & Suddarth’s Textbook of Medical-Surgical Nursing Vol. 1&2 : 12th edition: Lippincott Williams & Wilkins :1996 b.

A preterm newborn, approximately 30 weeks’ gestation, is admitted to the newborn intensive care unit. The baby exhibits respiratory distress, including tachypnea, retractions, and expiratory grunting. a. Identify the two most common causes for respiratory distress in this baby. b. Explain the etiology of the two causes identified. Causes Premature baby Etiology There is limited pulmonary blood flow which result from the collapsed state of the fetal lungs— from poor vascular development in general and an immature capillary network and because of increased pulmonary vascular resistance, the major portion of fetal blood is shunted from the lungs by way of the ductus arteriosus and foramen ovale.

What are fetal consequences of mothers with hyperphenylalaninemia who are not receiving a phenylalanine-restricted diet? Explain how these occur. According to Wikipedia The fetal consequences are neurologic symptoms, seizues and PKU which lead to mental retardation and death. (Wkipedia (2014) para 3&4) Phenylalanine is one of many essential nutrients. It is used by the body to make cells and other materials which are necessary for the body to work properly. Our bodies requires a certain amount of phenylalanine to make, neurotransmitters, tooth enamel, hormones, digestive enzymes,antibodies, hair, eye color pigmentation, skin cells and toe nails. The cells in our brain make chemicals called 12erformance12tters. Neurotransmitters transmit messages from ane nerve cell to another within our brain. The body needs a certain amount of phenylalanine to make these chemicals. Too much phenylalanine and not enough tyrosine interferes with the formation and 12erformance of neurotransmitters. When phenylalanine levels are in treatment range, neurotransmitters can deliver clear messages. When phenylalanine levels are ELEVATED, neurotransmitters CANNOT deliver clear messages.(BIOCHEMISTRY (2013) pp 22-29) Sources: Chapter One Handout: BIOCHEMISTRY 2013.
