You have been assigned to care for a woman who was recently admitted for advanced cancer, and who reports ongoing fatigue. Her husband offers observations about his wife's fatigue. Which statement by the husband indicates the most correct understanding of his wife's fatigue?

A. "She sleeps quite a bit, so she shouldn't be as tired as she is."
B. "She's lost some weight. I know she'll feel better if she eats more."
C. "She's been in pain. If we control that maybe, she'll have more energy."
D. "She seems moody, so we need to cheer her up and make her laugh."

C. She's been in pain. If we control that, maybe she'll have more energy.

Explanation:Considering the husbands observation, from the under lister option, pain is the only option that has a direct relation with fatigue because as a result of the pain, shell lose some sleep which directly makes are feel fatique. Catching enough sleep reduces stress level which in turn reduces level of fatique.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
