Extract:
Question 1 of 5

Correct Answer: C
Rationale: Answer C is the 'odd answer' and correct. Walking improves circulation by developing muscles that support blood vessels. Massaging may dislodge clots, elevating the bed is not specific to circulation, and propping feet reduces venous pooling but is less effective than walking.
Question 2 of 5
The nurse must know that the most accurate oxygen delivery system available is
Correct Answer: A
Rationale: The most accurate way to deliver oxygen to the client is through a Venturi system such as the Venti Mask. The Venti Mask is a high flow device that entrains room air into a reservoir device on the mask and mixes the room air with 100% oxygen. The size of the opening to the reservoir determines the concentration of oxygen. The client's respiratory rate and respiratory pattern do not affect the concentration of oxygen delivered. The maximum amount of oxygen that can be delivered by this system is 53%.
