A nurse is collecting data on a client who is to receive a blood transfusion. Which of the following data is the nurse's priority before the transfusion begins?

A.

Skin color

B.

Temperature

C.

Hemoglobin level

D.

Fluid intake

Answer and Explanation

The Correct Answer is B

A. Skin color: While skin color can show signs of reactions, it is a secondary measure. Temperature changes can be more immediately significant in assessing transfusion reactions.

 

B. Temperature: Temperature is the priority because a fever can indicate an infection or may develop as a sign of a transfusion reaction. Monitoring baseline temperature helps quickly identify febrile reactions to the transfusion.

 

C. Hemoglobin level: Although important to verify, the hemoglobin level is part of the overall assessment but does not directly predict or prevent transfusion reactions.

 

D. Fluid intake: Fluid intake is monitored for fluid overload risk but is not as immediate in the prevention of transfusion reactions.

Correct Answer is C

Explanation

A. Red blood cells (RBCs) 5.0 million/mm³ (F 4.2–5.4; M 4.7–6.1): This RBC count is within normal limits and does not indicate a concern related to thrombocytopenia.

B. Hemoglobin 14.5 g/100 mL (F 12–16; M 14–18): Hemoglobin is within normal limits and is not an immediate concern for a patient with ITP, as thrombocytopenia primarily affects platelets, not hemoglobin levels.

C. Platelets 50,000/mm³ (150,000–400,000): A platelet count of 50,000/mm³ is significantly below the normal range and poses a risk for bleeding, which is the primary concern in ITP (immune thrombocytopenic purpura).

D. White blood cells (WBCs) 7,400/mm³ (5,000–10,000): The WBC count is normal and not directly related to thrombocytopenia in ITP, which specifically affects platelets.

Correct Answer is C

Explanation

A. Hip: While “hip” can sometimes colloquially refer to the iliac crest, it is not commonly used to describe the specific site for aspiration outside of the iliac crest.

B. Cervical spine: The cervical spine is not a site used for bone marrow aspiration due to its inaccessibility and proximity to critical structures.

C. Sternum: The sternum is a common site for bone marrow aspiration in adults as it provides direct access to the marrow.

D. Humerus: The humerus is generally not used for bone marrow aspirations as it does not provide as accessible or large an area for aspiration.
