Multiple choice questions
1 What action would you take if a specimen had a biohazard sticker on it?
a Double bag it, in a self-sealing bag, and wear gloves if handling the specimen.
b Wear gloves if handling the specimen, ring ahead and tell the laboratory the sample is on its way.
c Wear goggles and underfill the sample bottle.
d Wear appropriate PPE and overfill the bottle.
2 What is the best way to avoid a haematoma forming when undertaking venepuncture?
a Tap the vein hard which will ‘get the vein up’, especially if the patient has fragile veins. This will avoid bruising afterwards.
b It is unavoidable and an acceptable consequence of the procedure. This should be explained and documented in the patient’s notes.
c Choosing a soft, bouncy vein that refills when depressed and is easily detected, and advising the patient to keep their arm straight whilst firm pressure is applied.
d Apply pressure to the vein early before the needle is removed, then get the patient to bend the arm at a right angle whilst applying firm pressure.
3 How do you ensure the correct blood to culture ratio when obtaining a blood culture specimen from an adult patient?
a Collect at least 10 mL of blood.
b Collect at least 5 mL of blood.
c Collect blood until the specimen bottle stops filling.
d Collect as much blood as the vein will give you.
4 If blood is being taken for other tests, and a patient requires collection of blood cultures, which should come first to reduce the risk of contamination?
a Inoculate the aerobic culture first.
b Take the other blood tests first.
c Inoculate the anaerobic culture first.
d The order does not matter as long as the bottles are clean.
5 Which of the following would indicate an infection?
a Hot, sweaty, a temperature of 36.5°C, and bradycardic.
b Temperature of 38.5°C, shivering, tachycardia and hypertensive.
c Raised WBC, elevated blood glucose and temperature of 36.0°C.
d Hypotensive, cold and clammy, and bradycardic.
6 Which of the following techniques is advisable when obtaining a urine specimen in order to minimize the contamination of a specimen?
a Clean around the urethral meatus prior to sample collection and get a midstream/clean catch urine specimen.
b Clean around the urethral meatus prior to sample collection and collect the first portion of urine as this is where the most bacteria will be.
c Do not clean the urethral meatus as we want these bacteria to analyse as well.
d Dip the urinalysis strip into the urine in a bedpan mixed with stool.
7 If a patient is experiencing dysphagia, which of the following investigations are they likely to have?
a Colonoscopy.
