Q4:How is acute inflammation different from chronic inflammation?
Acute inflammation is characterized by the predominance of lymphocytes
Acute inflammation is characterized by the predominance of monocytes.
Acute inflammation is characterized by the predominance of neutrophils.
Acute inflammation is characterized by the predominance of macrophages.
Q5:In respect to epidemiology, incidence refers to the:

Q6:Which of the following statements that describe the role of the cell cycle and cell proliferation in tissue healing and regeneration is INCORRECT?
Nervous tissue of the brain injured by stroke cannot regenerate
Bone marrow cells that give rise to the blood cells are examples of labile cells
Cardiac myocytes proliferate after cardiac injury
Hepatocytes remain in the resting stage of the cell cycle until stimulated
Q7:Unlike acute inflammation, chronic inflammation and granulomas are characterized by:
Aggregations of macrophages and lymphocytes
Neutrophil and macrophage recruitment
Vasodilation and edema
Fibrous tissue deposition
Q8:Which of the following statements characterizing Hodgkin lymphoma (HL) is true?

Defective B-cell immunity is a common problem in HL
Increased risk is associated with human papillomavirus infection
HL rarely involves lymph nodes
Q9:A patient exhibits prolonged bleeding time after injuries. Your clinical investigations of the standard coagulation tests revealed that the patient has prolonged prothrombin time (PT). 1) Which of the following coagulation pathways are affected? 2) What cellular or protein component of the pathway is deficient or dysfunction?
Common pathway only; von Willebrand factor (vWF)
Extrinsic and common pathway; XII
Intrinsic and common pathway; VII
Common pathway only; platelets
Q10:A 67-year-old Hispanic male presents to the ER with dizziness, headache, and vision changes. Chemistries are drawn and demonstrate a markedly elevated protein level; further testing reveals a monoclonal gammopathy of IgM. The patient's x-rays are notable for multiple “punched out” bony defects, especially in the spine and skull. What is the most likely explanation of the patient's symptoms?
Multiple myeloma
Chronic myelogenous leukemia
Hodgkin’s lymphoma
Acute lymphocytic leukemia
Q11:The primary warning signs of acute leukemia are:
Swollen lymph nodes, weight gain, headache, easy bruising
Fatigue, pallor, weight loss, recurrent infections, easy bruising, bleeding
Bleeding, abdominal pain, and fever
Bone pain, weight loss, fever, and headache
Q12:The thrombolytic agents used in treatment of a thrombosis to a coronary artery acts by:
Reducing the likelihood of fibrin clot formation
Interfering with clotting factor synthesis
Stimulating the formation of plasmin
Interfering with platelet aggregation
Q13:Which of the following statements best describes the effects of hyperglycemia on the cardiovascular system?
High glucose initiates endothelial injury and atherosclerosis
High glucose stimulates reduced homocysteine leading to atherosclerosis
High glucose interacts with blood lipids weakening the vessel wall
High glucose increases blood lipid levels
Q14:A patient presents with complaints of difficulty breathing and looks pale. The patient experiences excessive perspiration and his or her electrocardiogram shows an irregular rhythm. Which other finding will indicate that the patient may have developed myocardial infarction?
Multiple nitroglycerin (NTG) do not relieve the pain
Nitroglycerin (NTG) administration relieves the pain
Aspirin relieves the pain
Rest relieves the symptoms
Atrial fibrillation; P wave
Atrial flutter; P wave
Premature ventricular contraction; R wave
Atrial flutter; T wave
Q16:A nurse is reviewing the results of a diagnostic test of a patient who is being moved out of the intensive care unit. A cardiac troponin level assay was performed while the patient was in the intensive care unit, which indicated high levels of troponin. Which condition was the patient diagnosed with?
Thrombosis
Atrioventricular block
Acute myocardial infarction
Stable angina
Q17:In general, the most life-threatening arrhythmias cause:
Regurgitation of blood flow
Rapid atrial contractions
Under-filling of the ventricles by the atria
Ineffective ventricular contractions
Q18:Rest is beneficial in relieving the pain associated with stable angina because rest allows:
Increased venous return to the heart
Increased blood pressure decreasing coronary flow
Ischemic and conduction disorders
The dilation of the coronary arteries
Normal levels of coronary circulation is restored
Q19:A patient is found to have a disproportionately enlarged interventricular septum with an eccentrically thick left ventricle. Which condition would be indicated in the patient?
Dilated cardiomyopathy
Systolic dysfunction
Aortic valve stenosis
Hypertrophic cardiomyopathy
Q20:Which of the following is the most probable cause for increased secretion of renin due to heart failure?
Increased renal blood flow
Pulmonary congestion
Hypertension
Low cardiac output
Q21:A nurse is assessing a patient diagnosed with secondary pulmonary hypertension. The increase in the pulmonary artery pressure has led to the patient’s elevated pulmonary venous pressure. Which condition does the nurse predict to occur in the patient?
Pulmonary edema
Restrictive lung disease
Valvular
Chronic bronchitis
Asthma
Q22:The goal of therapies employed reducing the risk of deep venous thrombosis is to prevent the likelihood of _____.
Decubitus ulcers
Vasculitis
Pulmonary embolism
Infection
Q23:A primary health-care provider finds that a client is suffering from symptoms such as jugular venous distension, ascites, hepatomegaly, and lower limb edema. What clinical condition is most likely the cause of these findings affecting the cardiovascular system?
Pulmonary hypertension
Cor pulmonale
Acute asthma
Stable angina
Q24:Forward heart failure can be simply defined as:
