Correct Answer is A
Explanation
A. Using a 10-mL syringe filled with cleansing solution provides appropriate pressure for effective wound irrigation.
B. Drying the wound bed with gauze squares is not typically recommended as it may disrupt healing and cause trauma to the wound.
C. Cleansing the wound with cotton balls may leave fibers behind and is not the most effective method of wound irrigation.
D. Holding the syringe tip 2.5 cm (1 in) above the wound is incorrect; the tip should be inserted into the wound to facilitate thorough irrigation.
Correct Answer is C
Explanation
A. This technique is used for children, not adults. To straighten the ear canal for adults, the pinna should be pulled upwards and back.
B. Cleansing the outer ear with isopropyl alcohol is not typically necessary before administering otic medication and may cause irritation to the delicate skin of the ear canal.
C. Holding the dropper 1 cm away allows for better control and accuracy when directing the medication droplets into the ear canal. This helps ensure the medication reaches the intended area within the middle ear. Holding the dropper too close could accidentally touch the ear canal or eardrum, causing discomfort or even injury. Maintaining a slight distance helps prevent the dropper tip from contaminating the ear canal with skin flora from the client or the nurse's hand.
D. While some otic medications might recommend staying still for a short time after administration, 10 minutes is an excessive timeframe for most medications.
