A patient is undergoing a transesophageal echocardiogram (TEE). What statement indicates inaccurate understanding of the procedure by the patient? A. The test displays the heart valve function B. I have to not eat or drink after midnight C. I will be sedated during the procedure D. The ultrasound gel will be cold on my chest
D. A TEE does not require ultrasound gel to be placed on the patients chest. All other answers are true regarding the procedure.
A new graduate nurse is learning about Continuous Renal Replacement Therapy (CRRT). The nurse knows the student understands the therapy's correct purpose by which statement? A. CRRT is temporary for critically ill patients with acute kidney failure. Hemodialysis is long term therapy for chronic kidney failure. B. CRRT is another option for those with chronic renal failure only. C. CRRT is used when patients need dialysis more quickly than they could get with hemodialysis D. CRRT is a version of peritoneal dialysis that patients can do on their own.
A is the correct answer. CRRT is used in critically ill patients with both acute and/or chronic renal failure. This therapy is used to pull fluid slower than traditional hemodialysis (HD) for patients in a critical setting. CRRT is not only used for chronic renal failure. CRRT is used to slowly pull fluid from patients over a course of days rather than quickly removing fluid like HD. CRRT is not a form of periotneal dialysis.

Round 3.864 to the nearest tenth place.
3.9 First, we must consider what position we are going to round. The question asks to round to the tenth place. The location of the tenth place is to the right of the decimal. Next, we need to consider how we are going to round. When rounding to the tenth place, we need to consider the number to the right of what we are rounding. In this question, the 8 is in the tenth place, so in order to round we must examine the number to the right of the 8, which is the 6 that is in the hundredths place. Now lets do some rounding. Looking at the hundredths place, 6 is a number indicating to round up (greater than 5, numbers round up). Therefore the tenths place is now 3.9
