The baby otherwise appears comfortable. On examination, respiratory rate is 40 and pulse oximetry (O2 blood saturation) is 80%. A right ventricular lift is palpated, and a harsh grade intensity 3/6 systolic ejection murmur is heard at the left upper sternal border. 29. Pulse oximetry measures O2 within the blood.

There is a history of smoking, hypertension, and recent hospitalisation. She had been recuperating at home, but on beginning to mobilise and walk, the right leg became painful, tender, and swollen. She currently takes the oral contraceptive pill. On examination, the right calf is 4 cm greater in circumference than the left when measured 10 cm below the tibial tuberosity. Superficial veins in the leg are more dilated on the right foot, and the right leg is slightly redder than the left. On palpation, there is some tenderness and slight warmth in the popliteal fossa behind the knee. 30. The most probable cause of this patient’s oedema is due to A. Fluid build-up due to her kidneys not working due to her hospital stay B. Inflammation due to damage to the muscle C. Blood that cannot return to the heart due to a blocked vein D. A previous undiagnosed ankle sprain 31. The most common complication of this condition is A. PE B. Stroke C. MI D. Renal artery blockage A 55-year-old man with a history of HTN (controlled with medication) and tobacco use presents with a 2-day history of back pain and an abdominal pulsating mass. He cannot identify any aggravating factors. 32. If you were to palpate the abdominal aorta, the best place to palpate it would be: A. At the xiphoid B. Above the umbilicus C. At the umbilicus D. Below the umbilicus Page | 6  CHI335 – Sample Theory Questions A 56-year-old male with a history of smoking presents with shortness of breath and cough. His symptoms began 3 days ago. He reports a chronic morning cough, productive with white sputum, which has increased over the past 2 days. He has had similar episodes each winter for the past 4 years. He has smoked 1 to 2 packs of cigarettes per day for 40 years and continues to smoke. He denies haemoptysis, chills, or weight loss and has not received any relief from over-the-counter cough preparations. When auscultating, the chest is silent with little sounds and seems to have a more prolonged expiration than inspiration; percussion is hyperresonant. 33. The reason for longer expiration is because: A. Reduced chest wall elasticity B. The body doesn’t need much air, and hence, it rests during this time and takes longer to expire C. Airways collapse on expiration, and hence, it’s harder to get all the air out, and more time is needed for this air to escape D. It’s a neurological problem, and the ANS is in trouble 34. What is the most probable diagnosis? A. Complicated asthma B. COPD C. Interstitial lung disease D. Lung tumour blocking the airway A 60-year-old woman with long-standing uncontrolled diabetes mellitus presents with feeling pins and needles in her fingers and toes.
