Answer to Question 1

A
The radial artery is the safest, most accessible site for puncture; it is superficial, is not adjacent to large veins, and usually has adequate collateral circulation by the ulnar artery. Its use is relatively painless if the periosteum is avoided, and it is used when Allen's test is positive. The brachial artery has reasonable collateral blood flow but is less superficial, is more difficult to palpate and stabilize, and carries increased risk for venous puncture; its use results in increased discomfort. The femoral artery should not be used by nurses without specialized training. The popliteal artery usually is not used.

Answer to Question 2

A
The device described is a Heimlich chest drain valve. Pneumovax is a pneumococcal vaccine that is effective against 23 common strains of Pneumococcus. A Pleurovac is the brand name of a water-seal set.
