ATI Perfusion Quizlet

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 case, with a platelet count of 42,000/�L, the count is not critically low, and the patient is not actively bleeding. Therefore, the nurse should consult with the healthcare provider before giving the transfusion. Choices B, C, and D are incorrect because the presence of petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and do not necessarily require immediate consultation before administering a platelet transfusion.

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. A low percentage of monocytes can indicate a viral infection. This is crucial information to communicate as it suggests a specific type of infection that may require targeted treatment. Choices B, C, and D do not directly relate to an infectious process and are within normal ranges, so they are not as urgent to communicate to the healthcare provider in this context.

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.

Correct Answer: C

Rationale: The correct answer is C: Numbness of the extremities. Numbness of the extremities is a common finding in patients with pernicious anemia, which is caused by cobalamin (vitamin B12) deficiency. This deficiency affects the peripheral nervous system, leading to neurological symptoms like numbness and tingling in the extremities. Choices A, B, and D are incorrect: Yellow-tinged sclerae is more indicative of jaundice or liver dysfunction, a shiny smooth tongue is seen in conditions like glossitis, and gum bleeding and tenderness are associated with periodontal disease or vitamin C deficiency, not pernicious anemia.
