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 A
Explanation
A. Heart rate: Adequate fluid resuscitation in burn patients helps to restore intravascular volume, improving circulation and perfusion. A decrease in heart rate indicates improved cardiac output and reduced compensatory tachycardia, suggesting adequate fluid replacement.
B. Weight: Fluid replacement can lead to an increase in weight due to the volume of fluids administered, not a decrease.
C. Urine output: Adequate fluid resuscitation typically increases urine output as renal perfusion improves.
D. Blood Pressure (BP): While BP can stabilize with adequate fluid resuscitation, it is not as direct an indicator as a decrease in heart rate in reflecting improved perfusion and hydration status.
Correct Answer is B
Explanation
A. Alcohol use disorder. While alcohol use disorder can lead to various health issues, it is not a direct cause of hearing loss.
B. Prolonged exposure to loud noises. Prolonged exposure to loud noises is a well-known risk factor for noise-induced hearing loss. This includes occupational noise exposure and listening to loud music.
C. Exposure to environmental toxins. Some environmental toxins, like certain chemicals and heavy metals, can lead to ototoxicity, which can damage the auditory system and cause hearing loss.
D. Contact with excessive heat. Excessive heat exposure is not directly linked to hearing loss. Hearing loss is more related to factors like noise exposure, ototoxic substances, and infections.
