Answer to Question 1

1

Rationale:. Cromolyn is a first-line therapy for prophylactic treatment of asthma; it is a mast-cell stabilizer, antiasthmatic, and antiallergic. It does not decrease the risk of infection. It is not a bronchodilator. The medication acts in part by stabilizing the cytoplasmic membrane of mast cells, thereby preventing release of histamine and other mediators. It does not eliminate the need for the rescue inhaler.

Answer to Question 2

4

Rationale: PICCs are intended to be used for clients who need long-term catheter placement. They can be left in place for several months. It is reasonable in cost because the catheter does not need routine replacement, as do traditional peripheral IV catheters. The catheter is more com-fortable for the client because there is no repeated venipuncture with catheter change. The cathe-ter is also very reliable. It is less likely to infiltrate and can be used for administration of a number of different types of medications.
