  Besides, she has corneal arcus, lid lag and retraction. She also has nasal obstruction and she has sweating with postnasal drip and goitre. Chest expansion has decreased and has stony dull percussion on right lung base with diminished vesicular breath sound, coarse crackles was auscultated. She has irregularly irregular heartbeats. Holosystolic murmur was auscultated on the mitral and tricuspid area which indicate regurgitation. She has bilateral ankle edema and bilateral metatarsophalangeal joint swelling with pain therefore she couldn’t walk.

She always worries about prognosis of her multiple chronic illness and has expressed the concern about the current health issue, she doesn’t want to become a burden to her husband. She is an non-drinker and ex-smoker with 30 packs per year and had quit smoking in 2000. She has lack of exercise and likes fatty and salty food. She had hypertension, diabetes mellitus, rheumatic heart disease and chronic obstructive pulmonary disease. Her family history includes ischemic heart disease, colon cancer and rheumatoid arthritis.2. Five Medical Problems of Ms.

Siu2.1 PneumoniaPneumonia is an infection that can be caused by bacteria, viruses, or fungi. It causes inflammation in alveoli. The alveoli are filled with fluid or pus, that leads to difficult in breathing (Normandin, B.

, 2017). Ms. Siu has decreased chest expansion with stony dull percussion on right lung base with diminished vesicular breath sound and crackles were auscultated. In addition, she has productive coughing of yellow sputum with streaks of blood, shortness of breath, fever, sweating, chills, chest pain, respiratory rate above 20 breaths per minute, oxygen saturation below 95 %, oxygen therapy initiated and dyspnoea which are the signs and symptoms of pneumonia (Normandin, B., 2017).

Pneumonia may cause dyspneic with compressing chest discomfort in the retrosternal region (Garikiparithi, 2017). In addition, Ms. Siu has heart disease, diabetes and chronic obstructive pulmonary disease which are the risk factors of developing pneumonia (Stöppler, M. C.,2017).2.

2 Rheumatoid ArthritisRheumatoid arthritis is a chronic inflammatory and autoimmune disorder that affects different body systems occurs when the immune system attacks own body tissues (Mayo Clinic Staff, 2017). Ms. Siu has joint pain, loss of joint function which she can’t walk due to joint pain, fever, fatigue, general weakness and decreased appetite which are the symptoms of  rheumatoid arthritis. In addition, rheumatoid arthritis may leads to heart problem and lung diseases causing chest pain with shortness of breath or coughing (Shiel, 2017).

The risk factors include family history , age between 40-60 and cigarette smoking (Mayo Clinic Staff, 2017). 2.3 HyperthyroidismHyperthyroidism is caused by over production of hormone thyroxine by thyroid gland which accelerate body’s metabolism and cause sudden rapid or irregular heartbeat and sweating (Mayo Clinic Staff, 2015). Ms. Siu has irregular heartbeat (arrhythmia) and rapid heartbeat of 120 bpm (tachycardia), anxiety, hand tremor, goiter, lid lag, eyelid retraction, sweating, general weakness and fatigue which are the symptoms of hyperthyroidism (Mayo Clinic Staff, 2015).2.

4 Coronary Artery DiseaseCoronary artery disease occurs when the arteries that supply blood to heart muscle has become damaged and narrowed due to the buildup of plaque on their inner walls (Mayo Clinic Staff , 2017). Ms. Siu has shortness of breath, chest pain, dizziness, sweating, and tachycardia which are the signs and symptoms of coronary artery disease (Beckerman, 2016). Smoking, high cholesterol and diabetes are the risk factors.  2.

5 Heart failure Heart failure is the inability of the heart to supply oxygen and nutrients to organs and tissues causing fluid to leak from capillary blood vessels (Kulick, D. L., & Wedro, B., 2017). Ms. Siu has presented with shortness of breath, fatigue, general weakness, loss of appetite, coughing, pounding or racing heart, problems thinking, swelling in the ankles, chest pain which are the signs and symptoms of heart failure (Oberg, E.

, & Guarneri, M., 2016). Furthermore, Ms. Siu has tricuspid regurgitation and mitral regurgitation as holosystolic murmurs were auscultated at the tricuspid area and mitral area, and she has lack of exercise which increase the chance of heart failure (Oberg, E., & Guarneri, M., 2016).3. Investigations for Ms.

Siu’s Medical Problems 3.1 Investigations for pneumoniaBlood test, chest X-ray and CT scan are suggested for investigations for pneumonia. A complete blood count blood test helps confirm an infection (Mayo Clinic Staff, 2017). Chest X-ray helps diagnose pneumonia and determine the extent and location of the infection (Mayo Clinic Staff, 2017) . A chest CT scan provides clearer images of the lungs that helps diagnose pneumonia by observing excessive fluids around the lungs  (Normandin, B., 2017).

3.2 Investigations for rheumatoid arthritisBlood test, MRI or ultrasound images are suggested for investigations for rheumatoid arthritis. Blood tests are run to look for antibodies and the levels of inflammation. MRI can help detecting rheumatoid arthritis (Arthritis Foundation, 2015). Ultrasound scanning can be done to help confirm and determine the severity of rheumatoid arthritis (Murphy, J., 2017).3.

3 Investigations for hyperthyroidismThyroid function blood test, ultrasounds and thyroid scan and uptake are suggested. Thyroid function blood test to test for the thyroid stimulating hormone level which controls the production of thyroid hormones can help diagnose hyperthyroidism (Marcin, J., 2016).

Ultrasounds can help measure the size of the entire thyroid gland and the masses within it. Ultrasounds can also determine whether a mass is solid or cystic (Marcin, J., 2016). Thyroid scan and uptake can reveal the area of the gland that cause the overactivity (Giorgi, A., & Cherney, K.

, 2017).3.4 Investigations for coronary artery diseaseCoronary artery disease can by diagnosed by echocardiogram, cardiac catheterization and angiogram and CT scan. Echocardiogram uses sound waves to produce images of the heart which helps determine whether all parts of the heart wall are contributing normally to the heart’s pumping activity (Mayo Clinic Staff, 2017). Cardiac catheterization and angiogram can be done to view the blood flow through the heart, a special dye is injected into coronary arteries that indicate narrow spots and blockages on the X-ray images, a balloon can be pushed and inflated to improve the blood flow in the coronary arteries if there are blockages that require treatments (Mayo Clinic Staff, 2017). CT scan shows the substance in the arteries that can narrow the arteries which help diagnose and determine the cause of coronary artery disease (Mayo Clinic Staff, 2017).3.

5 Investigations for heart failureHeart failure can be diagnosed by electrocardiogram, blood tests and echocardiography. Electrocardiogram help assess heart rate, rhythm, and the size of the ventricles and blood flow to the heart muscle (Kulick, D. L., & Wedro, B., 2017). B-type natriuretic peptide (BNP) blood test helps decide whether patient has shortness of breath from heart failure (Kulick, D.

L., & Wedro, B., 2017). Echocardiography assess the anatomy and function of the heart that helps evaluate heart valves and muscles. It allows to look at the blood flow and measure the ejection fraction of the heart (Kulick, D. L.

, & Wedro, B., 2017).4. Abnormal Findings in Investigations4.1 Abnormal findings in pneumoniaThe elevated of white blood cell count in the complete blood count blood test indicates an infection.

Appearance of white spots in the lungs in the chest X-ray indicates an infection (Teague, S., 2017) If there are atoll signs in chest CT scan, the peripheral consolidation represents the organizing pneumonia in the alveolar ducts (Raju, S., Ghosh, S.

, & Mehta, A. C., 2017).

4.2 Abnormal findings in rheumatoid arthritisAbnormal blood tests in rheumatoid arthritis include elevated erythrocyte sedimentation rate which confirms the amount of inflammation in the joints (Murphy, J., 2017). If MRI detects areas of increased fluid in bone marrow, it is the sign of the development of bony erosions (Arthritis Foundation, 2015). Bone erosion and synovial lining changes can be seen in ultrasound in patients with rheumatoid arthritis (Arthritis Foundation, 2015).4.3 Abnormal findings in hyperthyroidFor the thyroid function blood test, an abnormally low thyroid stimulating hormone indicates hyperthyroidism (Marcin, J., 2016).

An enlarged thyroid may be seen in the ultrasound (Marcin, J., 2016). For the thyroid scan, red spots on the image indicate abnormal growths in the thyroid (Giorgi, A., & Cherney, K., 2017).

4.4 Abnormal findings in coronary artery diseaseIf the echocardiogram shows parts that move weakly that may be damaged or receiving too little oxygen may indicate coronary artery disease (Mayo Clinic Staff, 2017). The cardiac catheterization and angiogram test can find plaque that are narrow the coronary arteries which indicate coronary artery disease (Pai, R. K., & Philippides, G.

, 2015). if If a substantial amount of calcium is discovered in the CT scan, it may indicate coronary artery disease (Mayo Clinic Staff, 2017).4.5 Abnormal findings in heart failureFor electrocardiogram, atrial and ventricular arrhythmias are common findings in patients with heart failure (Shamsham, F., & Mitchell, J.

, 2000). Elevated B-type natriuretic peptide in blood test indicates heart muscles overloaded and cause heart failure (Kulick, D. L., & Wedro, B., 2017). For the echocardiogram, the percentage of blood ejected with each beat below 50% indicate heart failure (Kulick, D. L.

, & Wedro, B., 2017).
