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 34-year old police constable complains of dizziness, unquenchable thirst and bed-wetting. There is no other past medical history except for an accident during a high-speed car chase 6 months ago. She looks unwell and exhausted.

 

2. A 71-year retired Army Colonel is brought into hospital by his daughter who complains that he is coughing up blood and has noted significant weight loss. On further questioning, her father has become increasingly confused and restless. With no significant past medical history, you are told that he is a heavy smoker with a 50 pack year history. Bloods show Cl- 83, HC03- 25, Na+ 126, K+ 4.3, serum osmolality 269.

 

3. 63-year old patient being treated for SIADH died on the ward. You are on the NPSA committee to review the physician in-charge. The doctor gave 500 ml IV 0.8% saline solution/24 hours according to the set guidelines, while on a Na+ correction regime of 19 mmol/24 hours. Why would the patient then die?

 

4. Adrenal pathology manifesting in hypertension, muscle cramps, weakness, headaches and paraesthesia. ABG shows metabolic alkalosis.
