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 ["A","B","C"]
Explanation
Choice A rationale:
Splinting the incision when coughing helps to minimize pain and discomfort, which can encourage deeper breathing and coughing. This is essential because deep breathing and coughing help to clear secretions from the lungs and prevent atelectasis (collapse of lung tissue).
Steps for splinting the incision:
Place a pillow or folded towel over the incision site.
Instruct the patient to apply gentle pressure to the pillow or towel with their hands when coughing or deep breathing. Encourage the patient to relax their abdominal muscles during coughing and deep breathing exercises.
Choice B rationale:
Sitting up in a chair and ambulating promote lung expansion and help to mobilize secretions. This is because gravity assists in moving secretions from the smaller airways into the larger airways, where they can be more easily coughed up.
Additional benefits of sitting up and ambulating: Improved circulation
Decreased risk of pneumonia Enhanced recovery from surgery Choice C rationale:
Using an incentive spirometer hourly helps to increase lung capacity and prevent atelectasis. The device encourages the patient to take slow, deep breaths, which helps to inflate the alveoli (air sacs) in the lungs.
Instructions for using an incentive spirometer:
Sit upright in a chair or bed.
Place the mouthpiece of the spirometer in your mouth and seal your lips around it.
Inhale slowly and deeply through the mouthpiece, aiming to raise the piston inside the device as high as possible. Hold your breath for 3-5 seconds.
Exhale slowly and completely through the mouthpiece.
Repeat the process 10-15 times per hour, or as instructed by your healthcare provider.
Correct Answer is D
Explanation
Rationale for Choice A:
While maintaining normal body temperature is important for overall health, it's not the most immediate priority in a patient with fluid volume deficit due to ongoing bleeding. Fluid volume status takes precedence over temperature regulation in this context.
Hypovolemia can lead to hypothermia, but addressing the fluid deficit directly will also help stabilize temperature.
Focusing solely on temperature could delay crucial interventions to address the fluid loss and potentially worsen the patient's condition.
Rationale for Choice B:
An intact surgical incision is essential for proper wound healing and prevention of infection. However, in the context of active bleeding, it's not the priority outcome.
Maintaining adequate fluid volume is crucial to ensure perfusion of tissues, delivery of oxygen and nutrients, and proper organ function—all of which take precedence over incision integrity in this acute situation.
Addressing the fluid deficit will indirectly support wound healing by promoting tissue perfusion and reducing the risk of complications.
Rationale for Choice C:
Patient education is important, but it's not the most immediate priority in a patient with active bleeding and fluid volume deficit.
The patient's ability to comprehend and implement measures to reduce fluid loss may be compromised due to the hypovolemic state and potential cognitive effects.
Focusing on patient education at this stage could delay essential interventions to address the fluid loss and potentially worsen the patient's condition.
Rationale for Choice D:
Urine output is a sensitive and reliable indicator of renal perfusion and overall fluid status. In a patient with fluid volume deficit, maintaining a urine output of at least 30 mL/hour is a key indicator that the kidneys are receiving adequate blood flow and that fluid volume is being restored.
This outcome directly addresses the fluid deficit and serves as a measurable goal for fluid replacement therapy.
It takes priority over other choices because it directly reflects the patient's fluid status and the effectiveness of interventions to address the bleeding and fluid loss.
