ATI Perfusion Quizlet

Correct Answer: B

Rationale: The correct answer is B: Heparin. An activated partial thromboplastin time (aPTT) level of 28 seconds indicates a prolonged time, which is associated with heparin administration. Heparin is an anticoagulant medication that affects the intrinsic pathway of the coagulation cascade, leading to an increased aPTT. Aspirin (choice A) affects platelet aggregation and does not directly impact aPTT. Warfarin (choice C) affects the extrinsic pathway of the coagulation cascade and is monitored using the international normalized ratio (INR), not aPTT. Erythropoietin (choice D) is not related to coagulation parameters.

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 to evaluate the effectiveness of opioid analgesics. In sickle cell crisis, pain is the most common symptom and is usually managed with large doses of continuous opioids. Monitoring fluid intake (Choice A) is important, but limiting fluids may not be necessary. Encouraging ambulation (Choice C) is generally good but may not be the priority during a sickle cell crisis. Educating the patient about nutrition (Choice D) is important for overall health but may not be the immediate focus during a crisis.

Correct Answer: B

Rationale: The correct answer is B. Unlicensed assistive personnel (UAP) can obtain the temperature, blood pressure, and pulse before a transfusion as their education includes measurement of vital signs. UAP would then report the vital signs to the registered nurse (RN). Option A is typically a nursing responsibility to ensure patient safety and avoid errors in patient identification. Option C involves cross-checking important details and ensuring accuracy, which is usually performed by nursing staff to prevent errors. Option D requires monitoring for potential adverse reactions during the transfusion, which is a nursing responsibility due to the need for assessment and intervention in case of complications.

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.
