The nurse is caring for a patient with a burn that is severely swollen, and the wound bed appears brown and yellow. The patient reports no pain. How should the nurse classify the depth of this burn?
Superficial partial-thickness.
Full-thickness.
Deep partial-thickness.
Deep full-thickness.
The Correct Answer is B
Choice A rationale
A superficial partial-thickness burn involves the destruction of the epidermis and possibly a portion of the dermis. The description provided does not match this type of burn.
Choice B rationale
A full-thickness burn involves total destruction of the epidermis and dermis, and in some cases, the underlying tissue, muscle, and bone. The description of the burn as severely swollen, with a wound bed that appears brown and yellow, and the patient reporting no pain, is consistent with a full-thickness burn.
Choice C rationale
A deep partial-thickness burn involves the destruction of the epidermis and upper layers of the dermis and injury to the deeper portions of the dermis. The description provided does not match this type of burn.
Choice D rationale
Deep full-thickness burns are a more severe form of full-thickness burns that extend beyond the dermis into deeper tissues. The description provided does not match this type of burn.

Correct Answer is ["42"]
Explanation
Step 1: Convert the volume from liters to milliliters. 1 liter = 1000 mL. Step 2: Convert the time from hours to minutes. 4 hours = 240 minutes.
Step 3: Calculate the rate in mL per minute. Rate = Volume ÷ Time = 1000 mL ÷ 240 min = 4.17 mL/min.
Step 4: Calculate the drops per minute. Drops per minute = Rate × Drop factor = 4.17 mL/min
× 10 gtt/mL = 41.7 gtt/min.
Step 5: Round off the result to the nearest whole number. 41.7 gtt/min rounds off to 42 gtt/min.
Correct Answer is ["0.4"]
Explanation
Step 1 is to determine the amount of penicillin in each milliliter (mL) of the available solution. The vial is labeled as “Penicillin 500,000 units/mL”.
Step 2 is to divide the prescribed dose by the concentration per mL. So, the calculation is 200,000 units ÷ 500,000 units/mL. The result is 0.4 mL.
