6 Nursing Management of Hematologic Conditions

Assessment and laboratory interpretation

Hematologic nursing care combines symptom assessment with careful interpretation of blood and coagulation results. Laboratory findings support—but do not replace—clinical assessment and diagnostic evaluation. Interpret results alongside symptoms, medical history, laboratory reference ranges, and relevant treatment protocols.

Anemia and red-cell production

Fatigue and exertional shortness of breath can accompany anemia. A low hemoglobin indicates anemia, and a low MCV indicates smaller-than-average red cells. When low ferritin is also present, the findings support depleted iron stores and suggest iron-deficiency anemia; the underlying cause still needs evaluation.

A reticulocyte count helps assess whether the marrow is responding appropriately. A low count can suggest that the marrow is not producing enough new red cells for the degree of anemia. A high count may occur when production increases in response to red-cell loss or destruction. Interpret the result with the rest of the clinical picture.

Blood cancers and urgent assessment

Leukemia and its treatment can impair normal blood-cell production, including the production of infection-fighting cells. A markedly low absolute neutrophil count together with a new fever requires prompt evaluation: notify the responsible clinician and follow the facility’s urgent fever/neutropenia protocol. Do not delay escalation, and follow local precautions to minimize infection risk.

A persistent, painless enlarged lymph node and unexplained night sweats warrant timely clinical evaluation. These findings alone do not confirm lymphoma. Lymphoma commonly involves lymph nodes or other lymphoid tissue, and diagnostic evaluation determines the cause and type; this may include examination of tissue.

Bleeding history and coagulation tests

Ask about the pattern and severity of bleeding, family history, and medicines that can affect bleeding. Recurrent nosebleeds, easy bruising, or prolonged bleeding after dental work are relevant findings.

Common initial tests include a CBC with platelet count, PT, and aPTT. Further studies depend on the findings and may include von Willebrand factor or specific factor assays. Normal screening results do not rule out every bleeding disorder.

PT and aPTT assess different parts of the coagulation system. PT/INR is commonly used to monitor warfarin, while aPTT can be used to monitor unfractionated heparin according to the treatment protocol. Medicines and other conditions can affect results, so interpret them using the clinical context and laboratory ranges.

Preventing and recognizing bleeding

When severe thrombocytopenia is present, bleeding precautions aim to prevent trauma, minimize avoidable punctures, and identify bleeding early. Appropriate actions include using a soft toothbrush, helping reduce injury risk, applying firm pressure after venipuncture, and checking the site for continued bleeding. Avoid unnecessary invasive procedures and follow prescribed precautions.

Check medication choices with the care team because some medicines can increase bleeding risk; do not assume that aspirin is appropriate. Promptly report new bleeding, severe headache, or a change in level of consciousness. New neurologic symptoms may signal serious bleeding and need urgent evaluation.

Possible clotting complications

New one-sided calf swelling, warmth, and tenderness can occur with deep-vein thrombosis. Promptly report these findings and follow the diagnostic and treatment plan, because a clot can travel to the lungs. Do not massage the affected limb.

Sudden shortness of breath or chest pain may signal pulmonary embolism and requires an emergency response.

Transfusion safety and suspected reactions

Before starting a transfusion, verify the client and blood component using the required bedside identification checks and facility policy. Match the client, prescription, and blood component according to the facility’s process. Obtain and document required baseline observations, then monitor according to local policy.

If chills, fever, or shortness of breath develop during a transfusion, treat the situation as urgent. Stop the transfusion, assess airway, breathing, and circulation, maintain IV access without flushing the existing line, and promptly notify the appropriate clinician and transfusion service. Complete required checks, documentation, and specimen or product handling according to facility policy.
