If a patient opts for an herbal supplement over a prescribed medication, what would be the nurse’s best response?

Choice A rationale:

Incorrect. Mixing insulin detemir and insulin aspart in the same syringe is generally not recommended due to the following reasons:

Altered Pharmacokinetics: Mixing insulins can potentially alter their absorption and action profiles, leading to unpredictable blood glucose control.

Stability Concerns: The compatibility of different insulins in a mixed solution is not always guaranteed, potentially leading to precipitation or decreased potency.

Dosing Accuracy: Drawing up mixed insulins accurately can be challenging, especially when different dosages are required for each type.

Manufacturer Recommendations: Insulin manufacturers typically advise against mixing different insulins unless specifically instructed by a healthcare professional.

Choice B rationale:

Incorrect. While the order of drawing up insulins may have a minor impact on mixing, it does not address the fundamental concerns of mixing different insulins in the same syringe. The primary issue is the potential for altered pharmacokinetics, stability concerns, and dosing accuracy, as explained in the rationale for Choice A.

Choice D rationale:

Incorrect. Rolling insulin bottles between the palms is a technique used to gently resuspend insulin particles that may have settled at the bottom. However, it does not pertain to the correct procedure for drawing up different insulins for administration.

Choice C rationale:

Correct. Administering insulin detemir and insulin aspart using separate syringes and different injection sites is the most appropriate approach for several reasons:

Maintains Pharmacokinetics: It ensures that each insulin maintains its intended absorption and action profile, promoting optimal blood glucose control.

Ensures Stability: Using separate syringes eliminates the risk of potential incompatibility issues that could arise from mixing insulins.

Promotes Dosing Accuracy: Drawing up insulins in separate syringes allows for greater precision in administering the correct dosage of each type.

Aligns with Manufacturer Guidelines: This approach adheres to the recommendations of insulin manufacturers, ensuring safe and effective administration.

Additional Considerations:

Nurses should always consult the latest insulin administration guidelines and individual patient needs for optimal care.

Proper education and counseling should be provided to patients who require multiple insulin injections to ensure adherence and understanding of correct administration techniques.

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.
