QUESTIONS NEED HELP!!!

For the first question, I'm guessing the patient has come in to a clinic for a procedure. None of the answers are correct by themselves, since the best answer would be to assess (vitals, ask the patient if they are anxious, etc). You wouldn't call the physician just based on a simple observation and no further assessment, what other things would the doc want to know? You wouldn't just reschedule the appointment. And you wouldn't give the patient O2 without assessing their need for O2 (or an order). So I guess that leaves answer D, but again this is moving straight to an intervention without assessing first, so there are no correct answers to this one.

For the second question, think of it this way: Your body likes to maintain a certain Cardiac output - which is the amount of blood your heart moves in a minute. Cardiac output is defined by your stroke volume (how much blood moves per beat) multiplied by your heart rate. If the stroke volume is lower because of a decreased overall fluid volume, how would your heart rate need to change in order to maintain your body's cardiac output goal?

Oxygen looks like the best choice in the first question to me, but was there language indicating it's ordered (remember, when you're relaying these questions, giving the exact wording is essential)? D looks like a bad choice because there's no indication that there is a procedure to explain. As Muno stated, assessment would be the logical answer, but it's not there. If you didn't leave any important info out when you posted it, I think we can safely say THIS IS A CRAPPY QUESTION!

The second one is really pretty easy. I was going to simply give you the answer, but I like the way Muno gave you just enough of a hint to try to egg you into figuring it out...
