For each scenario below, choose the most appropriate answer from the list above. Each option may be used once, more than once or not at all.
1. A 32 year old man is admitted to A&E with a week-long history of severe vomiting. He confessed to self-medication of his chronic dyspepsia. He was clinically severely dehydrated and had shallow respiration. His Arterial Blood Gas results were: pH 7.51, PO2 15 kPa, HCO3– 43 mmol/L. What would you expect his PCO2 (kPa) to be?
2. A 27 year old woman is found to have low haemoglobin on her first check up at her antenatal clinic. There are no physical abnormalities and she mentions she is getting along with her daily routines just fine. Her blood test reveals Hb 10.7 g/dL, WBC 7.2 x 109 /L, platelets 202 x 109 /L. What would you expect this patient’s MCV (fL) to be?
3. A 67 year old man presented to his GP with visible jaundice that he had noticed to be deepening in colour. He had no pain but noticed some weight loss and that his stools were pale. He was a heavy drinker, and was not on any drug therapy. His LFTs were: Bilirubin 250 µmol/L, AST 87 u/L, ALT 92 u/L. What would you expect his Alkaline phosphatise (u/L) to be?
4. An 85 year old woman is admitted to hospital presenting with severe shortness of breath and a productive cough. She is a heavy smoker. The FY2 doctor currently in A&E, having carried out an Arterial Blood Gas which demonstrated hypercapnia and respiratory acidosis, administers oxygen therapy. He uses a 24% Venturi mask at 2L/min to increase her O2 saturation which was 85% on admission. What is the percentage increase required to obtain the lower limit of the desired O2 saturation range for this patient?
5. A 20 year old man arrives at A&E with known diarrhoea and vomiting. His lips and tongue are dry with a reduced skin turgor. Observations of the patient reveal a respiratory rate of 34 and a fruity odour. In addition, an Arterial Blood Gas illustrated: pH 6.98, PaO2 45 kPa (on 60% O2), pCO2 2.24 kPa, Base Excess -18. The result for his blood glucose (mmol/L) is still pending however what would one expect it to be?
