The home care nurse is making a monthly visit to a client with a diagnosis of pernicious anemia who has been receiving a monthly injection of cyanocobalamin (vitamin B12). Before administering the injection, the nurse evaluates the effects of the medication and determines that a therapeutic effect is occurring if the client makes which statement? 1. "I feel really lightheaded."
2. "I no longer have any nausea."
3. "I have not had any pain in a month."
4. "I feel stronger and have a much better appetite."

i believe the answer is 3 but I'm not 100% sure

my biggest life lesson is that if you do something bad/wrong it comes straight back to you karma. one time this kid threw an snowball at me then he slipped on ice now that's karma.

explanation:

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
