ATI Perfusion Quizlet

Correct Answer: C

Rationale: The correct answer is C, 'Hemoglobin level.' Pallor of the skin and nail beds is a sign of anemia, which is characterized by a low hemoglobin level. Anemia is a condition where there is a decreased number of red blood cells or hemoglobin in the blood, leading to reduced oxygen-carrying capacity. Checking the hemoglobin level would help confirm the presence and severity of anemia, guiding further diagnostic and treatment interventions. Choices A, B, and D are incorrect because platelet count, neutrophil count, and white blood cell count are not typically associated with the pallor of the skin and nail beds, which are more indicative of an underlying anemic condition.

Correct Answer: B

Rationale: The correct answer is B. In chronic anemia, the hematocrit (Hct) value is a crucial indicator of the proportion of red blood cells in the blood. A hematocrit value of 38% indicates a lower than normal level of red blood cells, which aligns with the patient's symptoms of fatigue and palpitations. Choices A, C, and D are incorrect because a low RBC count, normal RBC indices, and a hemoglobin level of 8.6 g/dL do not specifically address the decreased red blood cell mass associated with chronic anemia.

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: A

Rationale: The correct answer is A. Platelet transfusions are not usually indicated until the platelet count is below 10,000 to 20,000/�L unless the patient is actively bleeding. In this scenario, the platelet count of 42,000/�L 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: C

Rationale: The correct answer is C because administering subcutaneous medications falls within the education and scope of practice of an LPN/LVN. Assessing the patient for signs and symptoms of infection, teaching the patient, and developing a discharge plan are tasks that require an RN level of education and scope of practice. LPN/LVNs can assist in patient care, but tasks that involve assessment, teaching, and care planning are typically the responsibility of an RN.
