The nurse knows that hemolytic to blood transfusions occur most often when the first milliliters of the infusion.
- A. 125
- B. 50
- C. 100
- D. 75
Correct Answer: B
Rationale: Hemolytic reactions strike early 50 mL often triggers as mismatched blood clashes, a rapid antigen-antibody storm. Later volumes (75-125) build on it; 100's common but not peak. Nurses watch those first drops, stopping at 50 mL's hint of fever or pain, a tight window in this transfusion trap.

The nurse reviews the laboratory results of a patient who is receiving chemotherapy. Which laboratory result is most important to report to the health care provider?
- A. Hematocrit 30%
- B. Platelets 95,000/µL
- C. Hemoglobin 10 g/L
- D. White blood cells (WBC) 2700/µL
Correct Answer: D
Rationale: WBC at 2700/µL post-chemo yells neutropenia infection risk's sky-high, outranking anemia (A, C) or platelets (B bleeding's later, under 20,000). Nurses in oncology report this stat low white cells can spiral to sepsis, a chemo killer needing urgent tweaks.
A nurse in the oncology clinic is providing preoperative education to a client just diagnosed with cancer. The client has been scheduled for surgery in 3 days. What action by the nurse is best?
- A. Call the client at home the next day to review teaching.
- B. Give the client information about a cancer support group.
- C. Provide all the preoperative instructions in writing.
- D. Reassure the client that surgery will be over soon.
Correct Answer: A
Rationale: A new cancer diagnosis combined with the urgency of surgery in three days can overwhelm a client, impairing their ability to process and retain preoperative instructions due to emotional stress and anxiety. Calling the client the next day to review teaching allows the nurse to reinforce key points, answer questions, and ensure comprehension when the client may be calmer and more receptive. While providing written instructions is helpful, it assumes literacy and may not address immediate confusion or emotional barriers. Offering support group information is valuable for long-term coping but doesn't prioritize the urgent need for surgical preparation. Reassuring the client that surgery will be over soon dismisses their concerns and doesn't enhance understanding. The follow-up call is the best action, as it aligns with adult learning principles and nursing's role in ensuring informed consent and readiness, reducing perioperative risks and anxiety for the client.
Which of the following cancer patients could potentially be placed together as roommates?
- A. A patient with a neutrophil count of 1000/mm³
- B. A patient who underwent debulking of a tumor to relieve pressure
- C. A patient receiving high-dose chemotherapy after a bone marrow harvest
- D. A patient who is post-op laminectomy for spinal cord compression
Correct Answer: B
Rationale: Roommate pairing hinges on infection risk and care needs. The debulking patient tumor reduced for symptom relief and post-laminectomy patient spinal decompression both underwent palliative surgeries, not inherently immunocompromised, making them compatible. A neutrophil count of 1000/mm³ signals moderate neutropenia, needing isolation to dodge infections. High-dose chemotherapy post-bone marrow harvest obliterates immunity, demanding strict protection. The surgical pair's stability, lacking acute immune suppression, allows safe cohabitation, a nurse's practical call to optimize space and reduce cross-infection risks in cancer care settings.
What is the result of bariatric surgery as a therapy for morbid obesity?
