Patient centered questions MCQs for assessment of "Clinical problem solving and Medical decision (62M)

A 62-year-old male with a history of long-standing diabetes mellitus and hypertension presented to the outpatient department with complaints of exertional shortness of breath and pedal edema since three years. He also complains of intermittent claudication of both lower limbs after walking for around 250 meters since last three years with improvement upon standing for a few minutes. He also complains of episodes of dizziness after walking and has been noted to have a regular daytime somnolence with nocturnal apneic episodes and snoring. He also complained of sudden diminished vision of one eye three months back.  

The general examination reveals a large central obesity and bilateral pedal edema along with hyperpigmentation of the skin and "peau de orange." His BMI is 34 kg/m2. 

On investigations, his pulmonary function test and 2D Echo and an adenosine driven thallium perfusion scan turn out to be normal. His Hb is 8g % with microcytic hypochromic anemia with reduced serum iron, reduced transferrin saturation and TIBC with normal serum ferritin. His serum creatinine is 1.9 mg % and his urine 24 hour protein excretion is around 2 g%. A polysomnography was done earlier. 

Which of the following parameter in the polysomnogram will likely be helpful in the management of his nighttime choking? 
  1. Pulmonary arterial O2 saturation
  2. Respiratory rate
  3. Apnea-hypopnea index
  4. Lower limb arterial doppler study
  5. Coronary angiogram

The general examination reveals a large central obesity and bilateral pedal edema along with hyperpigmentation of the skin and "peau de orange." His fundoscopy revealed a recovering vitreous hemorrhage with proliferative diabetic retinopathy. 

On investigations, his pulmonary function test and 2D Echo and an adenosine driven thallium perfusion scan turn out to be normal. His Hb is 8g % with microcytic hypochromic anemia with reduced serum iron, reduced transferrin saturation and TIBC with normal serum ferritin. His serum creatinine is 1.9 mg % and his urine 24 hour protein excretion is around 2 g%. His blood sugar profile is controlled on insulin glargine at night and bolus insulin thrice before meals. His Hba1c is 6.5. A sleep study showed multiple episodes of sleep apnoea during REM sleep and Doppler examination of lower limbs revealed normal arterial flow. His polysomniogram reports reveal apnea-hyponea index of 47. 

Which of the following is the best next step in the management of this patient? 

  1. Continuous positive airway pressure
  2. Reassurance 
  3. Only weight loss
  4. Surgical correction 
  5. Only positional therapy

57 Year Old female with goiter and thyrotoxicosis

This 57 year olf lafy presented with neck swelling, anxiety and tremor. Her medical information is attached below: We need to take a decision on this lady. To operate or not to operate. Now that our clinical suspicions of thyroticosis have been proved and malignancy not proved (not disproved either) what would be the next best step? Medical management for her thyrotoxicosis or still get an excision biopsy with sub total thyroidectomy (and subtotal thyroidectomy other than disproving malignancy will also become treatment for her hyperthyroidism). So which one should we prefer (if the family has no reservations from their side)?

A 55 year old man with childhood asthma and Acute exacerbation of COPD

This is a 55 year old man in ICU with severe hypercapnia refractory to positive pressure ventilation with PCO2 ranging from 100-120 mm of Hg after 24 hours of ventilation. He appeared to have a history of Bronchial asthma since childhood. Perhaps for the last 45 years. His last three years appear to have been spent in perennial shortness of breath and wheeze. He has a barrel shaped chest and his CXR pa shows pushed down diaphragms. He was referred from a nursing home on a ventilator ambulance and his ABG during admission was showing a PCO2 of 90. After 24 hours of ACMV with a RR of 20 and tidal volumes of 400 ml his PCO2 increased to 120s.  This case of AECOPD with resp. Acidosis on mechanical ventilator was found to have total WBC count increasing overtime (15300 (ICU 2nd Day)/ 18500/ 27500/ 35600 (13th day). So, we started empirically with Clavum & Augmentin and later on planned for meropenam & Colistin antibiotic based on further deterioration in Total WBC Count....
