Bleeding and transfusion
NCLEX bleeding chapter: acute hemolytic transfusion reaction steps, DIC cues, thrombocytopenia precautions, and sickle cell vaso-occlusive crisis priorities.
Bleeding and clotting items test whether you stop the dangerous product, protect a client who cannot clot, and treat pain and perfusion in sickle cell crisis without delay.
Transfusion reactions: stop first
Stay with the client for the first 15 minutes of a transfusion. When a reaction starts, the blood product stops before anything else.
- Stop the transfusion.
- Maintain IV access with normal saline (use new tubing per facility protocol).
- Notify the provider and blood bank; save the bag/tubing as directed.
- Assess ABCs and vitals; treat the specific reaction pathway ordered.
- Document and continue close monitoring (urine color, mentation, BP).
| Picture | Likely reaction lane |
|---|---|
| Early: fever, chills, flank/back pain, chest pain, hypotension, dark urine | Acute hemolytic (ABO incompatibility pattern) |
| Fever/chills without severe hemolysis signs | Febrile non-hemolytic (still stop and evaluate) |
| Urticaria alone | Allergic; stop and treat per order |
| Stridor, wheeze, hypotension | Anaphylaxis: epinephrine pathway after stopping the product |
| Dyspnea, crackles, hypertension during/after volume | TACO / volume overload pattern |
Safety
Never restart the same unit after a suspected hemolytic or anaphylactic reaction. The first move is always stop the blood.
DIC and low platelets
Disseminated intravascular coagulation consumes clotting factors and platelets. Expect bleeding from IV sites and mucous membranes, purpura or mottling, low platelets, and low fibrinogen. This is a critical-care escalation, not a local pressure-dressing problem alone.
- Very low platelet counts need bleeding precautions: avoid IM injections and rectal temperatures, use soft toothbrushes, prevent falls, and report new petechiae, hematuria, or headache.
- Handle the client gently. Automatic blood-pressure cycling and unnecessary invasive sticks add risk when counts are critically low.
Sickle cell vaso-occlusive crisis
Severe ischemic pain from sickled cells blocking microcirculation is an emergency of comfort and perfusion. Priority plans usually include opioids for severe pain, hydration, oxygen when hypoxic or as ordered, and rest. Do not withhold analgesia while waiting for every lab to print.
Priority map
| Picture | First move |
|---|---|
| Chills + back pain + dark urine during transfusion | Stop blood; saline IV; notify |
| Stridor/wheeze during transfusion | Stop blood; anaphylaxis pathway |
| IV/gum oozing + low fibrinogen/platelets | DIC escalation |
| Platelets 18,000 | Bleeding precautions |
| Sickle cell crisis with severe pain | Analgesia + hydration/O2 supports |
Must know
- 1Suspected transfusion reaction: stop the transfusion first. Keep the IV line open with normal saline (new tubing per protocol), notify the provider/blood bank, and monitor closely.
- 2Acute hemolytic clues early in a transfusion: chills, fever, low back/flank pain, chest pain, hypotension, dark urine.
- 3Anaphylactic transfusion picture (stridor, wheeze, hypotension): stop the product and treat as anaphylaxis (epinephrine pathway), not as a mild febrile reaction.
- 4DIC: simultaneous bleeding (IV sites, gums) and clotting clues with low platelets and low fibrinogen. Escalate; this is a consumptive coagulopathy.
- 5Platelets very low (e.g., under 20,000/microliter range): bleeding precautions (avoid IM, no rectal temps, soft toothbrush, fall prevention, watch for petechiae/bleeding).
- 6Sickle cell vaso-occlusive crisis priority: treat severe pain, hydrate, oxygenate as indicated, and avoid triggers. Pain control is not optional comfort care.
Memory hooks
Stop the blood, save the vein
First action in a transfusion reaction is clamp/stop the blood product. Keep venous access with saline so you can treat.
Bleed and clot together = DIC
Oozing from sticks plus mottling/new clots with crashing platelets and fibrinogen is DIC, not simple nosebleed care.
How it's tested
Stems put chills, back pain, and dark urine fifteen minutes into a transfusion, or gum/IV oozing with low fibrinogen. Distractors slow the blood instead of stopping it, or treat sickle cell crisis as “wait for labs before analgesia.”
