A client's most recent diagnostic imaging has revealed that lung cancer has metastasized to the bones and liver. What is the most likely mechanism by which the client's cancer cells spread?
Hematologic spread
Lymphatic circulation
Invasion
Angiogenesis
The Correct Answer is A
A. Hematologic spread: Hematologic spread (through the bloodstream) is a common mechanism for metastasis to distant organs like bones and liver. This is the most likely mechanism for the spread described.
B. Lymphatic circulation: Lymphatic spread often leads to regional lymph nodes rather than distant organs like bones and liver.
C. Invasion: Invasion involves local spread into adjacent tissues but does not typically account for distant metastasis.
D. Angiogenesis: Angiogenesis refers to the formation of new blood vessels to supply the tumor, not the mechanism by which cancer cells spread to distant sites.

Correct Answer is D
Explanation
A. Grab bars: Grab bars are useful for preventing falls in the bathroom but are unrelated to the client’s atrophy of olfactory organs, which affects the sense of smell.
B. Nonslip mats: Nonslip mats can help prevent falls but are not related to the client’s diminished sense of smell.
C. Baseboard heaters: Baseboard heaters are unrelated to olfactory atrophy and do not address the safety concerns associated with a reduced sense of smell.
D. A smoke detector: A smoke detector is essential for this client because the atrophy of olfactory organs means the client may not be able to detect the smell of smoke, increasing the risk of not noticing a fire.
