Answer to Question 1
A, B, D
It is important to:
1 . Know the cause or type of wound. Wounds caused by vascular insufficiency, diabetes mellitus, pressure, trauma, and surgery are all very different and must have an individualized treatment plan. Not knowing the cause of a wound can have serious negative effects if treatments that are contraindicated for certain types of wounds are used.
2 . Know the expected amount and type of wound exudate or drainage. Wounds with large amounts of drainage require more frequent dressing changes or need an absorptive dressing.
3 . Determine whether wound drainage tubes are present to prevent their accidental dislocation when you remove the old dressing.
Knowing the patient's blood type is not necessary for the purposes of changing the dressing unless you are expecting a bleeding complication, and then it would be important for the patient to have a blood type and screen done.
Answer to Question 2
C
Controlled substances are not kept in the individual patient drawer; they are kept in a larger locked drawer to keep them secure. The unit dose is the ordered dose of medication that the patient receives at one time. Each tablet or capsule is wrapped in a foil or paper container. Liquid doses come in prepackaged foil or paper cups. At a designated time each day, the pharmacist or a pharmacy technician refills the drawers in the cart with a fresh supply.
