Correct Answer: A

Rationale: The correct action to include in the plan of care for a thrombocytopenic patient is to avoid intramuscular injections. Thrombocytopenia is a condition characterized by a decreased number of platelets, which are essential for blood clotting. Intramuscular injections can pose a risk of bleeding in patients with low platelet counts. Encouraging increased oral fluids (choice B) is beneficial for hydration but does not directly address the risk of bleeding associated with thrombocytopenia. Checking temperature every 4 hours (choice C) is important for monitoring infection but does not specifically address the risk of bleeding. Increasing intake of iron-rich foods (choice D) is more related to addressing anemia, not the primary concern of bleeding in thrombocytopenia.

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: C

Rationale: The correct answer is C. Pernicious anemia is a condition where the body can't absorb enough vitamin B12. Treatment usually involves lifelong replacement of vitamin B12. In this case, the patient understanding the disorder is correctly demonstrated by choosing nasal spray or injections of vitamin B12 for replacement therapy. Choices A, B, and D are incorrect because increasing red meat/liver intake, stopping wine consumption, or taking a proton pump inhibitor like omeprazole do not address the primary issue of vitamin B12 absorption in pernicious anemia.

Correct Answer: A

Rationale: The correct answer is A. Platelet transfusions are not usually indicated until the platelet count is below 10,000 to 20,000/µL unless the patient is actively bleeding. In this scenario, the platelet count of 42,000/µL is not significantly low to warrant a platelet transfusion without active bleeding. Consulting with the healthcare provider is essential before giving the transfusion to ensure the appropriateness of the treatment. Choices B, C, and D are not directly related to the need for consulting before a platelet transfusion. Petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and may not necessarily contraindicate a platelet transfusion at this platelet count.

Correct Answer: D

Rationale: The correct answer is D, Absolute neutrophil count. Filgrastim (Neupogen) works by stimulating the production and function of neutrophils. Therefore, monitoring the Absolute neutrophil count is crucial to assess the effectiveness of filgrastim in increasing neutrophil levels. Choices A, B, and C are incorrect because platelet count, reticulocyte count, and total lymphocyte count do not directly reflect the effectiveness of filgrastim in increasing neutrophils, which are essential in fighting infections during chemotherapy.
