A postoperative abdominal surgery patient has been admitted to the surgical floor. The nurse is aware that wound healing is delayed due to complications.
Which conditions would prevent normal wound healing at the surgical site?
(Select all that apply.)
Hypovolemia
Poorly controlled blood glucose levels
Protein deficiency
Adequate hydration
Routine ambulation
Steroid therapy
Obesity
Vitamin C supplementation
Correct Answer : A,B,C,F,G
Rationale for each choice:
Choice A: Hypovolemia
Impaired perfusion: Hypovolemia, or a decrease in circulating blood volume, leads to reduced blood flow to the wound site. This means that less oxygen and nutrients are delivered to the tissues, which are essential for healing processes like cell growth and collagen synthesis.
Impaired oxygen delivery: Oxygen is crucial for white blood cells to fight infection and for fibroblasts to create new tissue. Hypovolemia can significantly hinder wound healing by reducing oxygen availability at the wound site.
Delayed inflammatory response: The inflammatory phase of wound healing relies on adequate blood flow to deliver immune cells and initiate tissue repair. Hypovolemia can delay this response, leading to prolonged inflammation and delayed healing.
Decreased fibroblast activity: Fibroblasts, the cells responsible for collagen production, require oxygen and nutrients to function effectively. Hypovolemia can impair fibroblast activity, leading to reduced collagen synthesis and delayed wound closure.
Choice B: Poorly controlled blood glucose levels
Impaired immune function: High blood glucose levels impair the function of white blood cells, making the body more susceptible to infections. Infections at the wound site can significantly delay healing.
Impaired collagen synthesis: Hyperglycemia can also impair collagen synthesis, which is essential for wound strength and closure.
Vascular damage: Chronically high blood glucose levels can damage blood vessels, leading to impaired blood flow and oxygen delivery to the wound site, further hindering healing.
Choice C: Protein deficiency
Impaired collagen synthesis: Protein is a crucial building block for collagen, the main structural protein in connective tissue. A lack of protein can lead to reduced collagen production, resulting in delayed wound healing and weaker scar tissue.
Impaired immune function: Protein is also essential for immune cell function. A deficiency can impair the body's ability to fight infections, increasing the risk of wound complications.
Choice D: Adequate hydration
Incorrect: Staying well-hydrated supports the body’s healing process by ensuring proper blood flow and nutrient transport, thus it does not impede wound healing.
Choice E: Routine ambulation
Incorrect: Early ambulation after surgery promotes healing by improving circulation and reducing the risk of complications like blood clots, making it beneficial rather than harmful.
Choice F: Steroid therapy
Immunosuppressive effects: Steroids suppress the immune system, making the body less able to fight infections and hindering the inflammatory phase of wound healing.
Decreased collagen synthesis: Steroids can also decrease collagen synthesis, leading to weaker wound tissue and delayed closure.
Choice G: Obesity
Impaired blood flow: Excess adipose tissue can compress blood vessels, reducing blood flow to the wound site and impairing oxygen and nutrient delivery.
Increased inflammation: Adipose tissue produces inflammatory cytokines, which can prolong the inflammatory phase of wound healing and delay tissue repair.
Higher risk of infection: The folds of skin in obese individuals can create moist environments that are more prone to bacterial growth and infection.
Choice H: Vitamin C supplementation
Incorrect: Vitamin C plays a key role in collagen formation and tissue repair, so it supports rather than hinders wound healing.

Correct Answer is C
Explanation
Choice A rationale:
Incorrect dosage form: Metformin is typically administered orally as a tablet or liquid suspension, not as a powder for reconstitution (PO).
Missing route of administration: The medication order does not specify the route of administration, such as oral (PO), intravenous (IV), or intramuscular (IM).
Potential for medication errors: The lack of clarity in the medication order could lead to errors in administration, such as giving the wrong dose or administering the medication by the wrong route.
Choice B rationale:
Incorrect dosage unit: Methotrexate is typically administered in milligrams (mg), not grams (g).
Potential for overdose: The order for 15.0 g of methotrexate is a very high dose that could lead to serious adverse effects, including toxicity and death.
Choice C rationale:
Correctly written: The medication order specifies the drug name (meropenem), the dose (1.0 g), the dosage form (IV), and the route of administration (IV).
Appropriate dosage range: The dose of 1.0 g of meropenem is within the typical dosage range for this antibiotic.
Clear and concise: The medication order is clear, concise, and easy to understand, which helps to reduce the risk of medication errors.
Choice D rationale:
Incorrect: While choices A and B are both incorrect, choice C is a correctly written medication order.
Correct Answer is C
Explanation
Choice A rationale:
Debridement refers to the removal of dead, damaged, or infected tissue to promote healing. It is not a term used to describe skin breakdown caused by moisture.
Choice B rationale:
Evisceration is the protrusion of internal organs through a wound or surgical incision. It is not relevant to the condition of perineal skin breakdown due to wetness.
Choice D rationale:
Dehiscence is the separation of a surgical wound. It is not applicable in this case, as there is no mention of a surgical wound.
Choice C rationale:
Maceration is a term used to describe skin that has become softened and broken down due to prolonged exposure to moisture. This is the most accurate term to describe the condition of perineal skin breakdown after sitting in wet underclothes for many hours.
Key features of maceration:
Skin softening: The skin becomes white and wrinkled, resembling a prune.
Epidermal loss: The outer layer of skin (epidermis) may slough off, leaving the underlying tissue exposed. Redness: The affected area may become red and inflamed.
Pain or tenderness: The area may be painful or tender to the touch.
Increased risk of infection: Macerated skin is more susceptible to infection due to the breakdown of the skin barrier. Causes of maceration:
Prolonged exposure to moisture: This can include sweat, urine, feces, wound drainage, or excessive bathing. Friction: Rubbing or chafing of the skin can also contribute to maceration.
Impaired circulation: Poor blood flow to the area can make it more vulnerable to maceration. Prevention of maceration:
Keep skin clean and dry: This is the most important step in preventing maceration. Change wet or soiled clothing or dressings promptly.
Apply barrier creams or ointments: These can help to protect the skin from moisture.
Use incontinence products: These can help to keep the skin dry if the patient is incontinent. Reposition the patient frequently: This helps to reduce pressure and friction on the skin.
