Answers

Answer 1

Answer:

A (10)

Explanation:

The teacher can choose 3 questions from 5 of them.

Therefore, we can say the equation is ₅C₃.

Given nacre = n! / r!(n-r)!

That is, 5! / 3!(2)!

= 5 x 4 / 2 x 1

= 20 / 2

Eldon is a patient who is using oxygen administered from a wall mount and nasal cannula. The nursing assistant is setting up his oxygen therapy. Which steps should be completed by the nursing assistant?

O checking that the flow rate is the correct level and that there are bubbles in the humidifier
O checking that there are no bubbles in the humidifier and that the flow rate is the correct level
O advising the patient against tampering with liquid oxygen and checking that there are no bubbles in the humidifier
O checking that the flow rate is the correct level and advising the patient against tampering with liquid oxygen

Answers

Answer:

B.

Explanation:

Answer A is incorrect because the nurse should be checking to make sure that bubbles are NOT in the humidifier. A is insinuating that there SHOULD be bubbles in the humidifier.

Answers C and D are incorrect because the nursing assistant's job does not entail educating the patient about how to and how not to work the machinery. She is in charge of making sure the patient is getting the oxygen she needs, making sure her tubes are clean, and overall checking the patient's physical health. So the best answer would be B.
