A patient with sepsis has a lactate of 2.1 mmol/L on admission and 4.3 mmol/L two hours later, despite IV fluids. What does this suggest?

1. AWorsening tissue perfusion that needs urgent reporting
2. BA normal response to IV fluids in the first hours

4. DExpected muscle activity from shivering in fever

An older adult takes lisinopril and furosemide and recently started daily ibuprofen for knee pain. The creatinine has risen from 1.0 to 1.8 mg/dL (88 to 159 µmol/L). What is the most likely cause?

1. AThe NSAID reduces kidney blood flow on top of the other two drugs
2. BA laboratory error, since ibuprofen has no effect on the kidney
3. CMore activity has increased the patient's muscle mass quickly

2. BGout is ruled out, as uric acid is always high in an attack

A patient with diabetes and chronic kidney disease had a CT scan with IV contrast. Two days later, the creatinine has risen from 1.4 to 2.0 mg/dL (124 to 177 µmol/L). Which action is most appropriate?

1. AReport it, monitor urine output and hold metformin until reviewed
2. BRestrict all fluids to protect the kidneys from more contrast
3. CGive extra metformin, because the glucose rises after contrast
4. DIgnore it, because contrast never affects kidney function
