39.) All of the following are sign or symptoms of aortic stenosis EXCEPT A. Angina B. Syncope C. Systolic murmur D. Hemoptysis E. Dyspnea

Answer Explained Aortic valve stenosis signs and symptoms typically develop when narrowing of the valve is severe and can include: Chest pain (angina) or tightness; Feeling faint or fainting with exertion; Shortness of breath, especially with exertion; Fatigue, especially during times of increased activity; Heart palpitations and heart murmur. http://www.mayoclinic.com/health/aortic-valve-stenosis/DS00418/DSECTION=symptoms.

27.) A 42 year-old female comes to the Urgent Care because of increasing shortness of breath. Vital signs reveal she is afebrile with respirations of 22, blood pressure 130/90 and heart rate 100 and regular. Physical exam of the chest reveals decreased fremitus with a prolonged expiration phase and low diaphragms. Which of the following is the most likely diagnosis? A. Pneumothorax B. Acute asthma attack C. Pleural effusion D. Atelectasis E. Lobar pneumonia

Answer Explained Asthma is predominantly a disease of inflammation with superimposed bronchospasm, leading to air trapping. As such, the normally resonant thorax becomes hyperresonant, reflecting the less dense quality of the air- filled thoracic tissue, and tactile fremitus is diminished. Additional asthma findings include prolonged expiration phase and hyperinflation reported on the chest x-ray. Prolonged inspiration phase of respiration is usually found in upper airway obstruction such as epiglottis or tonsillar abscess. Tactile fremitus is typically increased when there is increased lung tissue density in conditions including pneumonia with consolidation.

What do you think he has? A. Kawasaki disease B. Pulmonary hypertension C. Constrictive pericarditis D.Hypertrophic cardiomyopathy E. Pleural effusion

Answer Explained Constrictive pericarditis is most commonly caused by conditions or events that cause inflammation to develop around the heart, including heart surgery, radiation therapy and tuberculosis. A physical exam may show that your neck veins stick out, suggesting increased blood pressure in the area. This is called Kussmaul's sign. The doctor may note weak or distant heart sounds when listening to your chest with a stethoscope. The physical exam may also reveal liver swelling and fluid in the belly area. Lower extremity edema is common. Textbook of Cardiovascular Medicine. 9th ed. Philadelphia, Pa: Saunders Elsevier; 2011:chap75.

What is your diagnosis? A.Osteoarthritis B. Psoriatic arthritis C. Calcium pyrophosphate deposition disease D. Rheumatoid Arthritis E. Systemic Lupus Erythematosus

Answer Explained Early rheumatoid arthritis tends to affect your smaller joints first — particularly the joints that attach your fingers to your hands and your toes to your feet. As the disease progresses, symptoms often spread to the knees, ankles, elbows, hips and shoulders. In most cases, symptoms occur in the same joints on both sides of your body. If a member of your family has rheumatoid arthritis, you may have an increased risk of the disease. There is no one test or physical finding to confirm the diagnosis. Mayo Clinic; Ferri's Clinical Advisor 2011.

Answer Explained Factors that contribute to the development of reflux esophagitis include the caustic nature of the refluxate, the inability to clear the refluxate from the esophagus, the volume of gastric contents, and local mucosal protective functions. The main symptom of reflux esophagitis is heartburn, with or without regurgitation of gastric contents into the mouth, which worsens on bending over. Health Encyclopedia - Diseases and Conditions.

15.) A patient with type 2 diabetes and hypertension should be treated with which agent?? A. Alpha blocker B. Beta blocker C. Calcium channel blocker D. ACE Inhibitor E. Hydrochlorothiazide

Answer Explained Hypertension is a common comorbidity in patients with diabetes, and adequate control of blood pressure significantly reduces the risk of macrovascular and microvascular complications. Patients with diabetes should achieve a target blood pressure of less than 130/80 mm Hg. The use of angiotensin-converting enzyme inhibitors may slow progression to kidney failure and cardiovascular mortality; these agents are the preferred therapy for managing coexisting diabetes and hypertension.

Exam shows warm skin, lid lag, bounding pulses, bibasilar rales, and fine tremor. Which of the following is the most likely diagnosis? A. Myasthenia gravis B. Essential tremor C. Mercury poisoning D. Hyperthyroidism E. Decreased reticulocyte count

Answer Explained Individuals suffering from hyperthyroidism exhibit different common symptoms like hair loss, heat intolerance and anxiety. Although patients can experience significant increase in appetite, the loss of weight is evident. Additional signs include fatigue, weakness and muscle aches that affect the entire body. Furthermore, patients can also experience apathy, irritability and hyperactivity. It is also quite common for patients to have polydipsia, polyuria as well as depression. Aside from sweating, they can also experience pretibial myxedema, tremor and delirium. Patients are more likely to have dyspnea or shortness of breath, arrhythmias and palpitations. These signs are also accompanied by diarrhea, vomiting, nausea and loss of libido. When left untreated, this condition can even lead to more health problems, one of which is osteoporosis. Patients with hyperthyroidism may also show some minor ocular symptoms. These include the lid-lag, extra-ocular muscle weakness and eyelid retraction, the last symptom of which is often referred to as the hypothyroid stare.

What is the next most appropriate step? A. CBC and chemistry profile B. Pelvic and abdominal CT scan C. Retrograde pyelography D. Cystoscopy and biopsy E. Intravenous urogram

Answer Explained Most patients present with unexplained hematuria (gross or microscopic). Some patients present with anemia, and hematuria is detected during evaluation. Bladder cancer is suspected clinically. Urine cytology, which may detect malignant cells, may be done. Cystoscopy and biopsy of abnormal areas are usually also done initially because these tests are needed even if urine cytology is negative. The Merck Manual.

29.) A cardinal manifestation of the nephrotic syndrome is A. Granular casts B. Proteinuria C. Pyuria D. Hematuria E. Anuria

Answer Explained Nephrotic syndrome is characterized by high protein excretion, peripheral edema, and metabolic abnormalities. Proteinuria in nephrotic syndrome is due to increased permeability of the glomerular basement membrane to albumin and arises in response to alterations in both the size and charge barriers of the glomerular filtration apparatus. Albumin is the predominant protein excreted. Am Fam Physician - 15-NOV-2009; 80(10): 1129-34.

37.) A 60 year old man with history of chronic bronchitis presents with 3 days of increased dyspnea and cough with purulent sputum production. Which medication is NOT warranted for treatment at this time? A. Systemic corticosteroids B. Albuterol C. Mucomyst D. Antibiotic E. Theophylline

Answer Explained While therapy with short bursts of high-dose parenteral steroids is a mainstay of hospital management of acute exacerbations, rapid dosage reduction to the lowest oral dosage possible for long-term management is necessary to minimize long-term side effects. Inhaled ipratropium bromide (Atrovent) and sympathomimetic agents are for most patients the mainstays of therapy to provide relief of bronchospasm. Sympathomimetic agents such as albuterol (Proventil, Ventolin) provide more rapid bronchodilation. Antibiotics are probably helpful only in acute exacerbations of chronic bronchitis. http://www.aafp.org/afp/1998/0515/p2365.html. Mucomyst is used to treat chronic bronchitis. Mucomyst contains the medicine N-acetylcysteine which thins or loosens mucus in the airways or breathing tubes, making it easier to cough up. http://www.patienthealthinternational.com/content/product/mucomyst
