ATI Perfusion Quizlet

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: cobalamin (vitamin B12). Methotrexate can lead to a deficiency in cobalamin, resulting in megaloblastic anemia. Therefore, increasing the oral intake of cobalamin is essential to address this deficiency. Choice A, iron, is incorrect because megaloblastic anemia caused by methotrexate is not typically due to iron deficiency. Choice B, folic acid, is also incorrect as methotrexate does not directly cause folic acid deficiency. Choice D, ascorbic acid (vitamin C), is incorrect as it is not directly related to megaloblastic anemia caused by methotrexate; instead, cobalamin is the key vitamin that needs attention.

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: B

Rationale: The correct answer is B: Potential complication: infection. Patients with idiopathic aplastic anemia have pancytopenia, which puts them at a high risk for infections due to decreased production of all blood cells (red blood cells, white blood cells, and platelets). Infection is a significant concern in these patients. Choices A, C, and D are incorrect because seizures, neurogenic shock, and pulmonary edema are not typically associated with idiopathic aplastic anemia. While seizures can occur in some conditions that affect the brain, neurogenic shock is related to spinal cord injury, and pulmonary edema is more commonly seen in conditions like heart failure.

Correct Answer: A

Rationale: The correct answer is to check all stools for occult blood. With a platelet count of 18,000/�L, the patient is at a high risk of spontaneous bleeding. Checking stools for occult blood can help detect any internal bleeding early. Encouraging fluids and providing oral hygiene are important interventions in general, but in this case, monitoring for bleeding takes precedence. Checking the temperature every 4 hours is not directly related to the patient's current condition and platelet count.
