Nokea
The nurse instructor is best?
- A. Because of immunosuppression, the donor cells take over.
- B. In like a transfusion reaction because no perfect matches exist.
- C. The client's cells are fighting donor cells for dominance.
- D. The donor's cells are actually attacking the client's cells.
Correct Answer: D
Rationale: Graft versus host disease is an autoimmune-type process in which the donor cells recognize the client's cells as foreign and begin attacking them. The other answers are not accurate.

A client has a sickle cell crisis with extreme lower extremity pain. What comfort measure does the nurse delegate to the client?
- A. Apply ice packs to the client's legs.
- B. Elevate the client's legs on pillows.
- C. Keep the lower extremities warm.
- D. Place elastic bandage wraps on the client's legs.
Correct Answer: C
Rationale: During a sickle cell crisis, the tissue distal to the occlusion has decreased blood flow and ischemia, leading to pain. Keeping the legs warm helps improve comfort due to decreased blood flow causing coolness. Elevation or elastic bandages may further reduce perfusion, and ice packs are not indicated.
The nurse is caring for a client with leukemia who has the priority problem of fatigue. What action by the client indicates this need has been met?
- A. Doing activities of daily living (ADLs) using rest periods
- B. Helping plan a daily activity schedule
- C. Requesting a sleeping pill at night
- D. Telling visitors to leave when fatigued
Correct Answer: A
Rationale: Fatigue is a common problem for clients with leukemia. This client is managing his or her own ADLs using rest periods, which indicates an understanding of fatigue and how to control it. Helping to plan an activity schedule is a lesser indicator. Requesting a sleeping pill does not control fatigue during the day. Asking visitors to leave when tired is another lesser indicator. Managing ADLs using rest periods demonstrates the most comprehensive management strategy.
A nurse is preparing to administer a blood transfusion. What action is most important?
- A. Correctly identifying client using two identifiers
- B. Obtaining informed consent
- C. Placing the blood product with Ringer's lactate
- D. Staying with the client for the entire transfusion
Correct Answer: B
Rationale: Obtaining informed consent is critical as it ensures the client understands the procedure and risks, which is a priority before initiating a transfusion. Correctly identifying the client is also crucial but follows consent in priority if the facility requires it. Ringer's lactate is not used for blood transfusions, and staying for the entire transfusion is not necessary.
A client has heparin-induced thrombocytopenia (HIT). The student nurse asks how this is treated. About what drugs does the nurse instructor teach? (Select all that apply.)
- A. Argatroban (Argatroban)
- B. Bivalirudin (Angiomax)
- C. Clopidogrel (Plavix)
- D. Lepirudin (Refludan)
- E. Methylprednisolone (Solu-Medrol)
Correct Answer: A,B,D
Rationale: Argatroban, bivalirudin, and lepirudin are direct thrombin inhibitors used to treat HIT. Clopidogrel is an antiplatelet agent, and methylprednisolone is a steroid, neither used for HIT.
A client with sickle cell disease (SCD) takes hydroxyurea (Droxia). The client presents to the clinic reporting an increase in fatigue. What laboratory result should the nurse report immediately?
- A. Hematocrit: 25%
- B. Hemoglobin: 2.2 mg/dL
- C. Potassium: 3.2 mEq/L
- D. White blood cell count: 38,000/mm3
Correct Answer: D
Rationale: Although individuals with SCD often have elevated white blood cell counts, an extreme elevation like 38,000/mm3 could indicate leukemia, a serious complication of hydroxyurea, or a severe infection, both critical in SCD patients. Hematocrit and hemoglobin levels are typically low in SCD, and the potassium level, while slightly low, is less urgent.
