(B) long-acting octreotide was given six weeks prior to the scheduled treatment

(C) short-acting octreotide was given 48 hours prior to the scheduled treatment

(D) short-acting octreotide was given 72 hours prior to the scheduled treatment

2. A radiation treatment that is hypofractionated gives a:

(A) Lower daily radiation dose given daily

(B) Lower daily radiation dose given less than once a day

(C) Higher daily radiation dose given daily

(D) Higher daily radiation dose given less than once a day

3. Which factor negatively affects radiation treatment outcomes:

(A) A hemoglobin of 6 g/dL 

(B) Platelet count 90,000/mm3

(C) Continued abstinence from tobacco

(D) Recent completion of an antibiotic course

4. A patient with a history of lung irradiation 7 months ago notes dyspnea, a nonproductive cough, and fatigue for the past month despite finishing a course of antibiotics last week.  The nurse is suspicious of: 

(A) Post-infectious cough 

(B) Radiation pneumonitis 

(C) Tension pneumothorax 

(D) Pleural effusion

5. A patient with metastatic cancer to the bone finished radiation to her femur 48 hours ago and calls the office with a significant pain increase but is still able to walk despite the pain.  The nurse educates the patient that:

(A) This is an unexpected outcome, and they should proceed to the emergency room. 

(B) This is an unexpected outcome, and they should prepare for additional treatment. 

(C) This is an expected outcome, and they should continue to take their dexamethasone.

(D) This is an expected outcome, and they should continue to take their gabapentin.

Answer Key

1. A

Rationale: Long-acting octreotide should be discontinued 4 weeks prior to treatment initiation and short-acting octreotide should be discontinued 24 hours prior to treatment initiation

2. D

Rationale: Definition of hypofractionation is a higher daily dose given less than once daily 

Reference: McQuestion, M., Drapek, L.C., & Witt, M.E. (2021).  Manual for Radiation Oncology Nursing Practice and Education. Oncology Nursing Society, p. 9.

3. A

Rationale: Factors related to radiation-induced injury of healthy tissue include low hemoglobin, active smoking, and active infection.  There is no evidence that platelets affect radiation course. 

Reference: McQuestion, M., Drapek, L.C., & Witt, M.E. (2021).  Manual for Radiation Oncology Nursing Practice and Education. Oncology Nursing Society, p. 14-15.

4. B

Rationale: Radiation pneumonitis of the lungs can occur > 6 months after radiation in this area and can mimic pneumonia symptoms.

5. C

Rationale: Pain flairs after radiation to bony metastasis occurs between 24-48 hours following irradiation.  It is common in 40% and treated with steroids.
