Correct Answer: C

Rationale: The patient¢â‚¬â„¢s clinical manifestations are consistent with a febrile, nonhemolytic transfusion reaction. The transfusion should be stopped and antipyretics administered for the fever as ordered.

Correct Answer: D

Rationale: Before a liver and spleen scan, it is essential to assist the patient to a flat position. This position helps obtain clear images of the liver and spleen. Checking for iodine allergy (Choice A) is more relevant for procedures involving contrast dye, not a liver and spleen scan. Inserting a large-bore IV catheter (Choice B) may not be necessary for this specific procedure. Administering sedatives (Choice C) is not typically required for a liver and spleen scan, as the patient needs to remain still during the procedure.

Correct Answer: D

Rationale: A low white blood cell (WBC) count in an older patient is concerning as it indicates a potential compromise in the patient's immune function. White blood cells are crucial for fighting infections and a low count could lead to an increased risk of infections. Hematocrit, hemoglobin, and platelet count are important parameters to assess, but a low WBC count takes priority in this case due to its direct impact on immune health.

Correct Answer: B

Rationale: After a bone marrow aspiration, it is important to have the patient lie on the left side for 30 to 60 minutes to decrease the risk of bleeding. Elevating the head of the bed to 45 degrees does not directly address the risk of bleeding. Applying a sterile 2-inch gauze dressing to the site is important for wound care but does not specifically address post-procedural positioning. Using a half-inch sterile gauze to pack the wound is not necessary after a bone marrow aspiration.

Correct Answer: B

Rationale: The correct answer is B: Platelet count. The platelet count is severely decreased, indicating a risk for spontaneous bleeding, which is a critical condition requiring immediate attention. While heart rate, abdominal pain, and white blood cell count are important, a severely decreased platelet count poses a more imminent threat to the patient's health and requires urgent communication to the healthcare provider. The nurse should prioritize addressing this potentially life-threatening issue to ensure prompt intervention and management.
