Answer to Question 1

B
Feedback:
Drainage in an open drain occurs passively by gravity and capillary action, which is the movement of a liquid at the point of contact with a solid, which in this case is the gauze dressing. Open drains are flat, flexible tubes that provide a pathway for drainage toward the dressing. Closed drains are more efficient than open drains because they pull fluid by creating a vacuum or negative pressure. This is done by opening the vent on the receptacle, squeezing the drainage collection chamber, and then capping the vent.

Answer to Question 2

B
Feedback:
The nurse uses an alcohol-based hand rub as it provides the fastest and greatest reduction in microbial counts on the skin. Other advantages include: alcohol-based hand rubs are more accessible because they do not require sinks or water; they increase compliance because they are easier to perform; they reduce costs by eliminating paper towels and waste management; and they are less irritating and drying than soap because they contain emollients. They can kill viruses but do not alter viral replication. They do not kill skin cells and they are ineffective against some spores.
