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.

- B. The cancer will be cured if the entire tumor is surgically removed.
- C. I will need follow-up examinations for many years after treatment before I can be considered cured.
- D. Cancer is never cured, but the tumor can be controlled with surgery, chemotherapy, and radiation.
Correct Answer: C
Rationale: Stage III breast cancer's advanced local spread means long-term vigilance, not a quick cured' label. Five years recurrence-free is a milestone, but not universal some hit sooner, others never. Surgery alone won't cut it; chemo and radiation tag-team it. Never cured' overstates control's the goal, but cure's possible. Nurses in oncology drill this: years of follow-ups track sneaky recurrence, key for stage III's tricky prognosis.

A chemotherapy drug that causes alopecia is prescribed for a patient. Which action should the nurse take to support the patient's self-esteem?
- A. Encourage the patient to purchase a wig or hat to wear when hair loss begins.

Limiting contact isolates; gentle washing won't stop it follicles are toast. Regrowth is true but delayed. Nurses in oncology push this proactive step it's practical, empowering, and tackles the psychosocial hit head-on.

The nurse is admitting an oncology patient to the unit prior to surgery. The nurse reads in the electronic health record that the patient has just finished radiation therapy. With knowledge of the consequent health risks, the nurse should prioritize assessments related to what health problem?
- A. Cognitive deficits
- B. Impaired wound healing
- C. Cardiac tamponade
- D. Tumor lysis syndrome
Correct Answer: B
Rationale: Radiation pre-surgery zaps tissue impaired wound healing's the big risk, as it fries skin and vessels, slowing repair post-op. Cognitive deficits need brain radiation, not specified. Tamponade's rare, tied to chest radiation and fluid buildup. TLS hits post-chemo, not pre-surgery. Nurses in oncology lock onto skin checks and infection signs, knowing radiation's legacy can tank surgical outcomes if ignored.
