A medical assistant in a provider's office is cleaning a patient's jagged, contaminated wound. Which of the following actions should the assistant take?
Irrigate the wound with sterile normal saline.
Insert liquid bandage into the wound.
Wash the wound with soap and warm water.
Apply microporous tape to the wound.
The Correct Answer is A
A. Irrigate the wound with sterile normal saline. Irrigating the wound with sterile normal saline is the appropriate action for cleaning a contaminated wound, as it helps to remove debris and reduce the risk of infection.
B. Insert liquid bandage into the wound. A liquid bandage is not appropriate for a contaminated wound, especially if the wound is jagged, as it could trap contaminants inside.
C. Wash the wound with soap and warm water. While soap and water are good for general wound cleaning, sterile normal saline is preferred for contaminated wounds in a clinical setting to minimize irritation and infection.
D. Apply microporous tape to the wound. Microporous tape is used for securing dressings, not for cleaning wounds.

Correct Answer is B
Explanation
A. Tilt the head back slightly: Tilting the head back slightly is not the standard technique for administering ear drops to adolescents and adults.
B. Gently pull the pinna up and back: Pulling the pinna (outer ear) up and back helps to straighten the ear canal in adolescents and adults, allowing the drops to reach the eardrum more effectively.
C. Tilt the head slightly forward: Tilting the head slightly forward is not the correct position for administering ear drops.
D. Gently pull the pinna down and back: Pulling the pinna down and back is used for children under 3 years old, not for older children or adults.
