A form of cancer therapy wherein a beam of high-energy electromagnetic radiation desires the cancer ceils?
- A. surgery
- B. radiation therapy
- C. chemotherapy
- D. pallitive treatment Situation: The nurse is assigned in a counseling clinic about preventive measures for cancers.
Correct Answer: B
Rationale: Radiation therapy is a form of cancer treatment that uses a beam of high-energy electromagnetic radiation to target and destroy cancer cells. The high-energy radiation damages the DNA in cancer cells, causing them to die or be unable to multiply. By precisely targeting the tumor with these radiation beams, radiation therapy helps to minimize damage to surrounding healthy tissues. This form of therapy is an essential component in the treatment of many types of cancer, either alone or in combination with surgery, chemotherapy, or other treatments.

The nurse is teaching parents of a child with chronic renal failure (CRF) about the use of recombinant human erythropoietin (rHuEPO) subcutaneous injections. Which statement indicates the parents have understood the teaching?
- A. "These injections will help with the hypertension."
- B. "We're glad the injections only need to be given once a month."
- C. "The red blood cell count should begin to improve with these injections."
- D. "Urine output should begin to improve with these injections."
Correct Answer: C
Rationale: The correct statement indicating that the parents have understood the teaching is: "The red blood cell count should begin to improve with these injections." Recombinant human erythropoietin (rHuEPO) is a hormone used to stimulate red blood cell production in patients with chronic renal failure. By increasing red blood cell production, rHuEPO can help combat anemia, a common complication of chronic renal failure. Therefore, the improvement of the red blood cell count is an expected outcome of administering rHuEPO injections in patients with chronic renal failure. The other statements are not accurate regarding the effects of rHuEPO injections.

A patient is admitted for a splenectomy. Why is an injection of Vit. K ordered before surgery?
- A. To correct clotting problems
- B. To prevent postoperative infection
- C. To promote healing
- D. To dry secretions
Correct Answer: A
Rationale: Vitamin K plays a crucial role in the production of clotting factors in the liver. Patients undergoing a splenectomy may be at an increased risk of bleeding during and after surgery due to the decreased availability of these clotting factors. Administering Vitamin K before the surgery helps to correct any potential clotting problems, ensuring proper hemostasis and reducing the risk of excessive bleeding during the procedure. This preoperative intervention can help optimize the patient's coagulation status and improve their outcomes postoperatively.
One nursing diagnosis for JRA is impaired physical mobility. Select all nursing interventions that apply.
- A. Give pain medication prior to ambulation.
- B. Assist with range-of-motion activities.
- C. Encourage the child to eat a high-fat diet.
- D. Provide oxygen as necessary.
Correct Answer: A
Rationale: Giving pain medication prior to ambulation can help alleviate discomfort and improve the child's ability to perform physical activities, thus promoting mobility.
Which is most important to document about immunizations in the child's health history?
- A. Dosage of immunizations received
- B. Occurrence of any reaction after an immunization
- C. The exact date the immunizations were received
- D. Practitioner who administered the immunizations
Correct Answer: C
Rationale: The most important information to document about immunizations in a child's health history is the exact date the immunizations were received. This information is crucial for tracking when the child is due for their next immunizations and to ensure they are following the recommended vaccination schedule. The dosage of immunizations received, occurrence of any reaction after an immunization, and the practitioner who administered the immunizations are also important details to document but the most critical one is the date to accurately maintain the vaccination records and plan future immunization appointments.
