CLT Treatment Protocols & Procedures 3

Question 1

Which procedure is used to remove antibody-coated red blood cells from a patient with warm autoimmune hemolytic anemia?

Accepted Answer

Erythrocytapheresis

Answer

Erythrocytapheresis (red cell apheresis) selectively removes abnormal red blood cells, while plasmapheresis removes plasma components.

Question 2

A diabetic patient has a fasting blood glucose of 52 mg/dL and is unconscious. What is the FIRST-LINE treatment?

Accepted Answer

IV 50% dextrose (D50W)

Answer

In an unconscious hypoglycemic patient unable to take oral glucose, IV dextrose (D50W) is the immediate treatment of choice.

Question 3

Which culture technique is MOST appropriate for detecting anaerobic bacteria from a wound specimen?

Accepted Answer

Thioglycolate broth incubated anaerobically

Answer

Thioglycolate broth creates a reduced oxygen environment suitable for anaerobic bacterial growth.

Question 4

A patient on heparin therapy develops heparin-induced thrombocytopenia (HIT). What is the correct treatment protocol?

Accepted Answer

Discontinue heparin and start a direct thrombin inhibitor

Answer

In HIT, heparin must be stopped immediately and an alternative anticoagulant (such as argatroban or bivalirudin) must be initiated to prevent thrombosis.

Question 5

Which anticoagulation protocol is MOST appropriate for a patient with renal failure requiring anticoagulation?

Accepted Answer

Unfractionated heparin

Answer

Unfractionated heparin is preferred in renal failure because it is not renally cleared, whereas LMWHs and DOACs accumulate in renal insufficiency.
