Which procedure is used to remove antibody-coated red blood cells from a patient with warm autoimmune hemolytic anemia?
Answer: Erythrocytapheresis
Erythrocytapheresis (red cell apheresis) selectively removes abnormal red blood cells, while plasmapheresis removes plasma components.
A diabetic patient has a fasting blood glucose of 52 mg/dL and is unconscious. What is the FIRST-LINE treatment?
Answer: IV 50% dextrose (D50W)
In an unconscious hypoglycemic patient unable to take oral glucose, IV dextrose (D50W) is the immediate treatment of choice.
Which culture technique is MOST appropriate for detecting anaerobic bacteria from a wound specimen?
Answer: Thioglycolate broth incubated anaerobically
Thioglycolate broth creates a reduced oxygen environment suitable for anaerobic bacterial growth.
A patient on heparin therapy develops heparin-induced thrombocytopenia (HIT). What is the correct treatment protocol?
Answer: Discontinue heparin and start a direct thrombin inhibitor
In HIT, heparin must be stopped immediately and an alternative anticoagulant (such as argatroban or bivalirudin) must be initiated to prevent thrombosis.
Which anticoagulation protocol is MOST appropriate for a patient with renal failure requiring anticoagulation?
Answer: Unfractionated heparin
Unfractionated heparin is preferred in renal failure because it is not renally cleared, whereas LMWHs and DOACs accumulate in renal insufficiency.
In polycythemia vera, which treatment reduces the risk of thrombotic complications most directly?
Answer: Therapeutic phlebotomy to target hematocrit below 45%
Maintaining hematocrit below 45% via therapeutic phlebotomy reduces blood viscosity and thrombotic risk in polycythemia vera.
Which gram stain and culture result would warrant immediate contact precautions and notification of infection control?
Answer: Gram-positive cocci in clusters — MRSA
MRSA (methicillin-resistant Staphylococcus aureus) is a reportable multidrug-resistant organism requiring immediate contact precautions and infection control notification.
