Which of the following prescriptions requires a Drug Enforcement Administration number?

A. Colonoscopy: A colonoscopy is an invasive procedure that requires written informed consent due to the associated risks and the need for detailed patient understanding.
B. Dilation and curettage: Dilation and curettage (D&C) is an invasive procedure requiring written informed consent, including an explanation of risks, benefits, and alternatives.
C. Venipuncture: For venipuncture, verbal consent is generally sufficient, as it is a minor procedure with minimal risk.
D. Cardiac stress test: A cardiac stress test, while less invasive, typically requires written informed consent due to potential risks and the need for patient understanding.

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.
