Answer to Question 1

B, D
A sterile object or field becomes contaminated by capillary action when a sterile surface comes in contact with a wet contaminated surface. Moisture seeps through a sterile package's protective covering, allowing microorganisms to travel to the sterile object. When stored sterile packages become wet, discard the objects immediately or send the equipment to be sterilized again. Spilling solution over a sterile drape contaminates the field unless the drape cannot be penetrated by moisture. The edges of a sterile field or container are contaminated. A 2.5-cm (1-inch) border around a sterile towel or drape is considered contaminated. A sterile object remains sterile only when touched by another sterile object. Place only sterile objects, such as sterile needles, on a sterile field. A sterile object or field out of the range of vision or an object held below a person's waist is contaminated. Never turn your back on a sterile tray or leave it unattended. Any object held below waist level is considered contaminated because you cannot view it at all times. Keep sterile objects either on or out over the sterile field.

Answer to Question 2

B
Carbohydrates and protein are sources of energy, each providing 4 kilocalories per gram (kcal/g). Lipids are a source of energy, providing 9 kcal/g. Two kcal/g is too small; 12 kcal/g is too high.
