Weight loss, wasting of body fat and muscle tissue, weakness, anorexia, and anemia, fatigue, sleep disturbances Question 4 10 / 10 pts Explain the TNM system: Your Answer: TNM system is a detailed staging system, created by AJCC, is used by cancer facilites. It classifies cancers into stages using 3 tumor components; Tumor, Nodes, Metastasis. T is size and spread of the primary tumor. N is how involved the lymph nodes. M is the extent of metastatic involvement. Classification: Tx, T0, Tis, T1-4 Nx, N0, N1-3 Mx, M0, M1 T is the size and local spread of the primary tumor. N is the involvement of the regional lymph nodes. M is the extent of the metastatic involvement. Question 5 10 / 10 pts 1. When would surgery be appropriate in the treatment of cancer? 2. Most chemotherapeutic drugs cause pancytopenia due to bone marrow suppression. What are the 3 possible adverse outcomes of this? Your Answer: 1. Surgery can be used if the tumor is solid and small with well-defines margins. Also can be used to treat oncologic emergencies and be used as prophylactic measures. 2. 3 possible adverse outcomes are neutropenia, anemia, thrombocytopenia. 1. Surgery is often the first treatment for solid tumors. If the tumor is small with well-defined margins, it can be removed completely. It is also used for oncologic emergencies and prophylactic surgery in high risk patients. 2.

Your Answer: Diagnosing is made by history, physical, and serological findings. Since some blood tests are more generic, results can be imprecise. Markers can be elevated in the presence of other diseases.Criteria for diagnosis: Evidence of an autoimmune reaction, immunological findings are not second to other conditions, and no other causes are found. There are over 80 identified, many with overlapping presentations. Many manifestations are nonspecific and are seen in other non-autoimmune diseases. Blood testing isn’t perfect either, as some tests are more generic and can be elevated in the presence of other diseases.

Your Answer: Portage Learning / NURS 231 Patho All Module 35 In autoimmune diseases, the immune sustem loses its ability to recognize self and produces autoantibodies, which act against host tissues Answer: In many autoimmune diseases, the immune system loses its ability to recognize self and produces what is called autoantibodies, which act against host tissues. Question 19 10 / 10 pts Short answer A 40-year-old man presents with cough and shortness of breath. After an H&P and chest films, it is determined he has pneumocystis carinii pneumonia (PCP). The provider does an HIV test, which is positive. Upon further testing, the man’s CD4+ cell count is 100 cells/µL and his viral load is 250,000 copies/mL. (1) Why did the provider do an HIV test after the man was diagnosed with PCP? (2) What classification does this man fall into based on his CD4+ count and symptomatology, and why? Your Answer: 1) PCP is a lung infection that affects people with weakened immune systems, such as those infected with HIV. It is listed as an opportunistic infection. 2) Overt AIDS. Patient's CD4+ cell count is below 200 cells/uL. Patient also presented with an AIDS- defining illness, such as PCP. (1) Opportunistic infections are those common organisms that do not produce infection without impaired immune function. (2) The last phase, or AIDS illness, occurs when the CD4+ cell count falls to less than 200 cells/µL or exhibits an AIDS-defining illness. The risk of opportunistic infections and death increases significantly when the CD4+ cell count falls below 200 cells/µL.

These signs and symptoms are most likely to be associated with which one of the following laboratory abnormalities? Correct Answer Sickle cells on peripheral blood smear Loss of intrinsic factor You Answered Decreased erythropoietin Decreased ferritin Question 13 2.5 / 2.5 pts Multiple Choice: Portage Learning / NURS 231 Patho All Module Which of the following is NOT true of vitamin B12 deficiency anemia? 46 49 In stable angina, with exertion, the vessels cannot properly vasodilate. This can cause chest pain, tightness or shortness of breath. Heart is stable at rest, but cannot keep up with the exertion demand. It is relieved with rest and/or use of nitroglycerin. With increasing occlusion of the coronary vessel, the demands of the resting heart may become too great. Unstable agina is when patient has angina without exertion. Rest is insuffient, but can be releived with nitroglycerin. If the plaque ruptures, complete occulsion can occur. This can lead to lack of oxygen to tissues in the heart and muscle can die. This is myocardial infarction. Chest pain unrelieved by rest, sharp pain down left arm, vomitting are signs of distress. Emergency/hospital interventions are needed. With atherosclerotic disease, the coronary vessel lumens are narrowed and blood supply to the heart is diminished. With exertion, the vessels cannot adequately vasodilate. This can manifest as chest pain or tightness and/or shortness of breath. Stable angina- The heart is stable at rest but cannot keep up with the demand of exertion. Stable angina typically has a >70% stenosis of the coronary arteries. It is relieved by rest or nitroglycerin (vasodilator). Unstable angina- With increasing occlusion of the coronary vessel(s), the demands of the resting heart may become too great. When the patient experiences angina without exertion, or when the level of exertion necessary to cause anginal symptoms decreases, this is called unstable angina. It can be relieved by nitroglycerin, but not rest. Unstable angina means one or more coronary vessels is nearly totally occluded. Myocardial infarction- If a plaque ruptures, coronary thrombosis can cause complete occlusion. If collateral flow is inadequate, the tissue supplied becomes ischemic. Without oxygen, a portion of the muscle can die. MI can present as chest pain unrelieved by rest, sometimes radiating down the left ram or into the jaw or neck, dyspnea, nausea/vomiting, sweating, and/or other signs of distress. Other symptoms include a crushing pain or like “something is sitting on my chest.” Women may present with weakness, fatigue, shortness of breath, or GI complaints. Symptoms are not relieved by nitroglycerin. Question 19 10 / 10 pts 1. Name 2 lifestyle changes to prevent further progression of atherosclerotic diseases: 2. Name 2 medications used to treat someone with coronary artery disease and their mechanisms of action: Your Answer: 1. Stop smoking and frequent exercise 2. ACE inhibitors prevent conversion of angiotensin I to angiotensin II, which decreases vasocontriction, aldosterone production, sodium and water retiention by the kidneys. Diuretics promote the excretion of fluids, reducing preload. 1. Reduction in fat intake, quitting smoking, weight loss, exercise 2. Aspirin or other platelet inhibitors are used to prevent thrombosis formation. Beta-blockers and calcium channel blockers (CCB) – both decrease the heart rate and contractile force – can be initiated to decrease the heart’s demand of oxygen. CCB also increase coronary vasodilatation and decrease coronary vasospasm. Nitrates are used to quickly dilate the coronary vessels. Nitrates also dilate veins, decreasing the heart’s work by decreasing preload and afterload. Question 20 2.5 / 2.5 pts Multiple Choice: 50 With increasing occlusion of the coronary vessel(s), the demands of the resting heart may become too great. When the patient experiences angina without exertion, or when the level of exertion necessary to cause anginal symptoms decreases, this is called what? Stable angina Correct! Unstable angina Myocardial infarction Question 21 2.5 / 2.5 pts Multiple Choice: Which of the following is NOT a risk factor for hypertension? Correct!

Lymphocytes Question 12 2.5 / 2.5 pts Multiple Choice: Alpha-1 antitrypsin deficiency is most likely seen in which disease process? Bronchial asthma Chronic bronchitis Correct! Emphysema Bronchiectasis Question 13 2.5 / 2.5 pts Multiple Choice: Histologically, chronic bronchitis would exhibit each of the following except: Correct! Enlargement of the airspaces 61 Increase in goblet cells Fibrosis of the bronchiolar wall 64 An 18-year-old woman is admitted to the ER with a suspected drug overdose. Her respiratory rate is slow (4-6 breaths/minute) and shallow. Arterial blood gases reveal a PCO2 of 80 mm Hg and a PO2 of 60 mm Hg. What is the cause of this women’s high PCO2 and low PO2? Hypoventilation almost always causes an increase in PCO2. Explain. Your Answer: The patient has decreased ventilation, impaired alveolar ventilation. This causes an increase in plasma PCO2 and decrease in PO2. She cannot expire the air at a normal rate resulting in accumulation of CO2. Hypoventilation is when there is a reduced amount of air entering the lungs and alveoli. This results in decrease of oxygen and increase of CO2 in the blood. Breathing is often too shallow or too slow. Respiratory acidosis; with a decreased respiratory rate, you are not exhaling enough carbon dioxide and it accumulates. Question 17 10 / 10 pts Short answer: Explain why the oxygen flow rate for people with COPD is normally titrated to maintain the arterial PO2 between 60 and 65 mm Hg. Your Answer: Those with oxygen therapy, its vital not to supplement with too much oxygen. The respirator center in the medulla has adapted to elevated CO2 levels, no longer responding to increases in PCO2. A decrease in PO2 becomes the stimulus for respiration. If oxygen is given at too high of rate, the respiratory drive and stimulus is supressed. Their medullary respiratory center has adapted to the elevated CO2 levels and no longer responds to increases in PCO2. Therefore, a decrease in PO2 becomes the stimulus for respiration. If oxygen is given at too high of a rate, it suppresses the stimulus and the respiratory drive. Question 18 10 / 10 pts Short answer: 65 1.) Your patient’s lung showed the following: what is the only treatment that can delay the progression of this disease? 2.) Which is more soluble in plasma: carbon dioxide or oxygen?

Your Answer: day went on, the tingling sensation got worse, and they started to have difficulty speaking. The patient’s spouse reported that they were slurring their words. Past medical history includes a diagnosis of diabetes and hypercholesteremia. By the time they are evaluated, their symptoms start to subside. The tingling disappears and their speech returns to normal. What do you suspect this patient has experienced? What evidence is there to support that diagnosis? Your Answer: The patient experienced a TIA, transient ischemic attack, or mini stroke. The patient's symptoms, tingling sensation, slurred speech, difficulty speaking, are signs of a stroke. However, with TIA, the symptoms/signs, will resolve within 24 hours. The patient's medical history of diabetes and hypercholesteremia also are risk factors for stroke. Answer: This patient has experienced a TIA. They have experienced symptoms consistent with oxygen deprivation to the brain, however their symptoms subsided within 24 hours of their onset. Question 26 10 / 10 pts Long Answer Essay A 75-year-old male is brought to the emergency department via ambulance at 5 pm. The patient’s spouse reports that when they woke up (approximately at 6 am) he reported to her that he was having some blurred vision but decided to go about his day. As the day progressed, he started experiencing tingling and feelings of weakness on the entire left side of his body. He has a past medical history of diabetes. Based upon these symptoms and past medical history, what do you suspect this patient is experiencing? How would you confirm this diagnosis? What treatment should be administered? Explain why you chose that treatment. Your Answer: This patient is experiencing a stroke. A CT scan and MRI will be ordered to determine the type of stroke and rule out possible other disorders. A vasular image will be done to determine source of the block. Since its been over 4 hours since symptom onset, the window to safely administer tPA has passed. A catheter based method is necessary. This will mechanically break the clot and deliver drugs directly to the clot itself. A stent might be place as well. Answer: This patient is more than likely experiencing an ischemic stroke. A CT scan and MRI would be needed to determine if a clot was blocking blood flow to the brain tissue and to rule out a hemorrhagic stroke. If a clot is found, this patient would need to be re-perfused through catheter- base methods as they are outside of the 3-4.5 treatment window for the use of tPA drugs. Question 27 10 / 10 pts Long Answer Essay A patient is being seen in your office with a primary complaint of daytime fatigue that has lasted for the past 2 months. They go on to tell you that they are having difficulty with work performance and are constantly on edge. You suspect they have chronic insomnia. What are the 4 primary symptoms of insomnia? Describe a nonpharmacologic treatment plan that you can prescribe for this patient. Your Answer: The 4 symptoms are: DIfficulty initiating sleep Difficulty maintaining sleep Waking up too early Chronic nonrestorative (poor)sleep For a primary insomnia diagnosis, patient must exhibit at least 3 symptoms from the list above and at least one sympton during wake hours, such as poor work performance and irritability. Nonpharmacologic treatment will be patient education and good sleep hygiene, sleep habits.
