A charge nurse is teaching a newly licensed nurse about risk factors for chronic myelogenous leukemia (CML). Which of the following information should the nurse include?
Exposure to radiation
Family history
Another type of cancer
Genetic mutation
The Correct Answer is A
A. Exposure to radiation - Exposure to high levels of radiation is a known risk factor for developing CML. Historical data, such as from atomic bomb survivors, show a higher incidence of leukemia, including CML, among those exposed to radiation.
B. Family history - CML is generally not associated with a significant familial risk. It is more commonly linked to acquired genetic mutations rather than inherited predispositions.
C. Another type of cancer - Having another type of cancer does not directly increase the risk of developing CML. However, treatments for other cancers, like radiation therapy, might increase risk.
D. Genetic mutation - The development of CML is associated with a specific acquired genetic mutation known as the Philadelphia chromosome (translocation between chromosomes 9 and 22), rather than inherited genetic mutations.

Correct Answer is B
Explanation
A. Consume foods high in potassium: Potassium is important for ear health, but there is no direct evidence that high-potassium foods alone reduce the risk of hearing loss.
B. Avoid smoking tobacco products: Smoking is associated with an increased risk of hearing loss due to its negative effects on blood flow to the cochlea and the auditory nerve. Avoiding smoking can reduce the risk of hearing damage.
C. Increase oral intake of water: While staying hydrated is good for overall health, it does not specifically impact hearing loss risk.
D. Limit alcohol to two drinks daily: Excessive alcohol consumption can affect hearing, but moderation is not directly associated with preventing hearing loss as effectively as avoiding smoking.
Correct Answer is A
Explanation
A. Avoid crowds - Neutropenic patients are highly susceptible to infections. Crowded places increase the risk of exposure to pathogens.
B. Eat plenty of fresh fruits and vegetables - While generally healthy, fresh fruits and vegetables can harbor bacteria, posing a risk for infection in neutropenic individuals. Cooked or properly washed and peeled produce is safer.
C. Take temperature weekly - Neutropenic patients should monitor their temperature daily, not weekly, to detect infections early.
D. Perform mild exercise, such as gardening - Gardening can expose individuals to soil-borne organisms that could lead to infections. Indoor exercises or those that don’t involve potential pathogen exposure are safer.
