Med GEMS Questions Part 2 Flashcards
A 21 year old woman with transfusion dependent beta thalassaemia normally has a transfusion every two weeks.

She is clinically well, apyrexial. She denies losing weight or night sweats. Her appetite is good.
What blood test should be ordered to further investigate the raised white cell count given her history?
Reticulocyte count

ECG shows p wave flattening, hyperacute T waves and a broadened QRS compared to an ECG 5 days prior.
What electrolyte abnormality is responsible for the ECG changes?

Hookworm
What blood test is a measure of fibrin degredation products and may reflect activity of the body’s anticoagulant system?
D-dimer
A patient is investigated for tiredness.
Blood tests show a low haemoglobin.
A peripheral blood smear shows microcytosis, hypochromia and the presence of cigar cells.
What is the likely diagnosis?
Iron deficiency anaemia
What is the term given to a group of genetic condition which affect the synthesis of the haem molecule, which is vital for the function of haemoglobin, peroxidase and P450 enzymes?
Poryphyria
What blood film finding may be found in multiple myeloma and is reflective of a paraproteinaemia?

A 63 year old man is admitted to hospital with severe pain in his right flank which comes and goes in waves. He cannot remain still while the pain is at its worst.
He has had similar episodes in the past which resolved without him seeing a doctor. He has no other past medical history of note.
Blood tests reveal an elevated calcium (3.1, NR 2.2-2.6); a normocytic anaemia (Hb 90, NR >120); and an elevated urea and creatinine.
After further questioning, he reports pain in his back and his legs which has progressively been worsening.
What is the likely underlying diagnosis?
Multiple myeloma
A 55 year old smoker presents to ED with unilateral left arm swelling which developed over a few days.
A D dimer is elevated. Platelets are elevated. An ultrasound doppler of the left arm does not reveal the presence of a blood clot. Other blood tests are unremarkable.

Multiple myeloma is a lymphoproliferative malignancy of what type of immune cell?
Plasma cells
What protein is classically mutated in hereditary spherocytosis?
Spectrin
Secretion of what hormone is responsible for the development of polycythaemia in COPD?
Erythropoietin
A medical student is unsure about what cell she is looking at under the microscope. She is looking a peripheral blood film.
She describes a cell that looks plentiful on the film and has a multisegmented nucleus. It is approximately twice the size of the red cells she can see on the film.
What cell is she describing?
Neutrophils
What condition is associated with infiltration of large numbers of megakaryocytes into bone marrow, an elevated platelet count and is associated with increased stroke risk?

A 3 year old boy is seen by his GP after his mother noted that his right knee had swollen during the night and become painful to the touch. This has happened multiple times before in the other knee and it has resolved spontaneously. The child appears well and has no fever. He is able to weight bear. He does not appear distressed by it. His brother has had similar symptoms.
His past medical history includes recurrent epistaxis and his mother says he bruises easily.
The GP suspects this may be a clotting disorder and orders a panel of bloods, including inflammatory markers and a clotting screen.
Given the most likely diagnosis, what blood test would you expect to be elevated?
APTT
