A nurse is evaluating a patient who has a stage 1 pressure injury. What findings should the nurse anticipate?
Full-thickness skin loss with visible bone.
Full-thickness skin loss with visible adipose tissue.
Skin remains intact with localized erythema.
Partial-thickness skin loss with red tissue in the wound bed.
The Correct Answer is C
Choice A rationale
Full-thickness skin loss with visible bone is characteristic of a stage 4 pressure injury, not a stage 1 pressure injury.
Choice B rationale
Full-thickness skin loss with visible adipose tissue is characteristic of a stage 3 pressure injury, not a stage 1 pressure injury.
Choice C rationale
In a stage 1 pressure injury, the skin remains intact with localized erythema. The area may be painful, firm, soft, warmer, or cooler compared to adjacent tissue.
Choice D rationale
Partial-thickness skin loss with red tissue in the wound bed is characteristic of a stage 2 pressure injury, not a stage 1 pressure injury.

Correct Answer is D
Explanation
Choice A rationale
Increased collagen is not a factor that would lead to a pressure injury in a client with impaired mobility. Collagen is a protein that helps in the formation of skin and other connective tissues.
Choice B rationale
Decreased serum calcium is not directly related to the development of pressure injuries. While calcium is important for bone health and muscle function, it does not play a direct role in skin integrity.
Choice C rationale
Increased muscle mass is not a risk factor for pressure injuries. In fact, good muscle mass can help distribute pressure more evenly and potentially reduce the risk of pressure injuries.
Choice D rationale
Decreased circulation is a major risk factor for the development of pressure injuries. When blood flow to an area of the body is reduced, the tissues in that area can become deprived of oxygen and nutrients, leading to cell death and the formation of pressure injuries.
Correct Answer is ["125"]
Explanation
Step 1 is to understand the question. The patient has been prescribed vancomycin 1 g in 250 mL dextrose 5% (D5W) to be administered over 2 hours via IV intermittent bolus. We need to calculate how many mL/hr the nurse should set the IV pump to deliver.
Step 2 is to calculate the rate. The total volume to be administered is 250 mL and the time for administration is 2 hours. So, the rate is 250 mL ÷ 2 hours = 125 mL/hr.
