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:
Inaccurate statement: While herbal supplements are derived from plant materials, this does not inherently guarantee their safety or non-toxicity. Some plants contain potent compounds that can have adverse effects, even in small doses.
Lack of regulation: Herbal supplements are not regulated by the FDA in the same way as prescription medications. This means that there is no guarantee of their purity, potency, or consistency.
Potential for interactions: Herbal supplements can interact with prescription medications, potentially leading to harmful side effects.
Choice B rationale:
Cost-related issue: The cost of herbal supplements can vary widely. While some may be less expensive than prescription medications, others can be quite costly.
Misleading focus: Emphasizing cost as a primary factor could lead patients to prioritize affordability over safety and effectiveness.
Choice C rationale:
Addresses quality concerns: This response directly addresses the lack of stringent quality standards for herbal supplements, highlighting a significant safety concern.
Encourages informed decision-making: This response encourages patients to carefully consider the potential risks and benefits of herbal supplements, prompting them to seek reliable information and discuss their choices with healthcare providers.
Choice D rationale:
Convenience vs. safety: While the convenience of herbal supplements may be appealing, this response does not address the potential safety concerns associated with their use.
Potential for misuse: Highlighting convenience could lead to patients using herbal supplements inappropriately or without necessary guidance from healthcare professionals.
Correct Answer is A
Explanation
Choice A rationale:
Standing orders are pre-approved orders that nurses can implement for specific patient situations without requiring a new order from a provider each time. They are designed to streamline care, promote efficiency, and ensure consistency in treatment. In this case, the standing order for EKGs on all cardiac unit admissions serves several key purposes:
