Answer to Question 1

A
Dry heat maintains temperature changes longer than moist heat treatments. Moist heat reduces the drying of skin and softens wound exudate. Moist heat also penetrates more deeply into tissue layers and conforms better to the body area being treated.

Answer to Question 2

A
A. Radial artery is the safest, most accessible site for puncture; it is superficial, is not adjacent to large veins, usually has adequate collateral circulation by ulnar artery, is relatively painless if periosteum is avoid, and is used when Allen's test is positive.
B. Brachial artery has reasonable collateral blood flow, is less superficial, is more difficult to palpate and stabilize, carries increased risk of venous puncture, and results in increased discomfort.
C. Femoral artery should not be used by nurses without specialized training.
D. Arterial blood may be obtained from areas where strong pulses are palpable: radial, brachial, or femoral artery.
