Chapter 32 : Assessment of Hematologic Function and Treatment Modalities Questions
Question 1 of 5
A patients diagnosis of atrial fibrillation has prompted the primary care provider to prescribe warfarin (Coumadin), an anticoagulant. When assessing the therapeutic response to this medication, what is the nurses most appropriate action?
Correct Answer: D
Rationale: The INR and aPTT serve as useful screening tools for evaluating a patients clotting ability and to monitor the therapeutic effectiveness of anticoagulant medications. The patients platelet level is not normally used as a short-term indicator of anticoagulation effectiveness. Assessing the patient for signs of myelosuppression and capillary refill time does not address the effectiveness of anticoagulants.
Question 2 of 5
A patient has been scheduled for a bone marrow biopsy and admits to the nurse that she is worried about the pain involved with the procedure. What patient education is most accurate?
Correct Answer: C
Rationale: Patients typically feel a pressure sensation as the needle is advanced into position. The actual aspiration always causes sharp, but brief pain, resulting from the suction exerted as the marrow is aspirated into the syringe; the patient should be warned about this. Stating, Ill try to help you keep your mind off the pain may increase the patients fears of pain, because this does not help the patient know what to expect.
Question 3 of 5
A patient is scheduled for a splenectomy. During discharge education, what teaching point should the nurse prioritize?
Correct Answer: B
Rationale: After splenectomy, the patient is instructed to seek prompt medical attention if even relatively minor symptoms of infection occur. Often, patients with high platelet counts have even higher counts after splenectomy, which can predispose them to serious thrombotic or hemorrhagic problems. However, this increase is usually transient and therefore often does not warrant additional treatment. Dietary modifications are not normally necessary and immunosuppressants would be strongly contraindicated.
Question 4 of 5
The nurses brief review of a patients electronic health record indicates that the patient regularly undergoes therapeutic phlebotomy. Which of the following rationales for this procedure is most plausible?
Correct Answer: A
Rationale: Persistently elevated hematocrit is an indication for therapeutic phlebotomy. It is not used to address excess or deficient plasma volume and is not related to stem cell function. Bone marrow biopsy is not an indication for therapeutic phlebotomy.
Question 5 of 5
A nurse has participated in organizing a blood donation drive at a local community center. Which of the following individuals would most likely be disallowed from donating blood?
Correct Answer: B
Rationale: For potential blood donors, systolic arterial BP should be 90 to 180 mm Hg, and the diastolic pressure should be 50 to 100 mm Hg. There is no absolute upper age limit. Donation 4 months ago does not preclude safe repeat donation and diabetes is not a contraindication.
