What is the first intervention of the nurse for changing the dressing to a painful burn?

Choice A rationale:

Aspiration prior to injection of enoxaparin is not recommended. Key reasons for this contraindication include:

Absence of Large Blood Vessels in Subcutaneous Tissue: Enoxaparin is administered subcutaneously, targeting the fatty tissue layer beneath the skin. This tissue generally lacks large blood vessels, significantly reducing the risk of accidental intravascular injection. Aspiration, traditionally intended to prevent such occurrences, becomes unnecessary in this context.

Potential for Hematoma Formation: The act of aspiration itself can create a vacuum within the subcutaneous tissue, leading to trauma and bleeding at the injection site. This can result in hematoma formation, causing discomfort and potential interference with medication absorption.

No Evidence of Benefit: Research studies have not demonstrated any clear advantages of aspiration when administering subcutaneous enoxaparin injections. In fact, some studies have suggested a potential increase in bruising and bleeding associated with aspiration.

Manufacturer Guidelines: Enoxaparin manufacturers explicitly advise against aspiration in their product instructions, aligning with current evidence-based practices.

Choice B rationale:

Massaging the injection site after administering enoxaparin is also not recommended.

Rationale for this contraindication:

Accelerated Absorption: Massaging can increase local blood flow, potentially accelerating the absorption of enoxaparin. This could lead to higher-than-intended drug levels in the bloodstream, increasing the risk of bleeding complications.

Discomfort and Hematoma Risk: Similar to aspiration, massage can create mechanical stress on the injection site, potentially causing bruising, discomfort, or hematoma formation.

Choice C rationale:

While a 1-mL syringe with a 32-gauge needle is a suitable option for subcutaneous injections, it's not the only correct choice. Considerations for syringe and needle selection:

Needle Length: The needle should be short enough to ensure subcutaneous administration, typically ranging from 5/8 to 1 inch in length.

Syringe Size: The syringe size should accommodate the volume of medication being administered, providing clear visibility of the dose.

Patient Comfort: Smaller-gauge needles (like 32-gauge) are often preferred for subcutaneous injections as they tend to cause less discomfort. However, other factors, such as medication viscosity and patient preferences, may influence needle selection.

Choice D rationale:

The abdomen is the preferred injection site for enoxaparin due to several reasons:

Abundant Subcutaneous Tissue: The abdomen generally has a thicker layer of subcutaneous tissue, providing ample space for medication absorption and reducing the risk of intramuscular injection.

Ease of Access: The abdomen is often easily accessible for self-injection or administration by a caregiver, promoting patient comfort and convenience.

Reduced Pain: Subcutaneous injections in the abdomen are typically less painful compared to other potential sites like the arms or thighs.

Additional considerations for enoxaparin administration:

Rotate Injection Sites: To prevent tissue damage and promote consistent absorption, it's crucial to rotate injection sites within the recommended areas (abdomen, thighs, upper buttocks).

Monitor for Adverse Effects: Observe for any signs of bleeding, bruising, or allergic reactions following enoxaparin administration.

Adhere to Storage Guidelines: Store enoxaparin at room temperature and protect it from light to ensure its efficacy.

Choice A rationale:

While providing meticulous oral care and allowing ice chips for dry mouth can promote comfort, it does not address the primary concern of absent bowel sounds.

Ice chips could potentially stimulate bowel activity, but this is not a reliable or recommended method for managing absent bowel sounds in the immediate postoperative period.

It's essential to prioritize actions that assess and address the potential causes of absent bowel sounds, as they can indicate serious complications.

Choice B rationale:

Notifying the surgeon immediately and preparing for emergency surgery is not the appropriate first course of action in this situation.

Emergency surgery would be considered only if there were clear signs of a life-threatening complication, such as bowel perforation or peritonitis.

These complications would typically present with additional symptoms such as severe abdominal pain, fever, and hemodynamic instability.

Absent bowel sounds alone, without other concerning signs, do not warrant immediate surgical intervention.

Choice D rationale:

Allowing the patient to have clear liquids as tolerated is not appropriate when bowel sounds are absent. Introducing oral intake before bowel function has returned can increase the risk of nausea, vomiting, and aspiration.

It's crucial to wait for the return of bowel sounds before initiating oral intake to ensure proper digestion and minimize complications.

Choice C rationale:

Keeping the patient NPO (nothing by mouth) is the most appropriate action when bowel sounds are absent after major abdominal surgery.

This allows the bowel to rest and recover from the surgical manipulation.

It also prevents potential complications such as aspiration and nausea/vomiting that could arise from premature oral intake.

Documenting the absence of bowel sounds in the patient's medical record is essential for communication among healthcare providers and for monitoring the patient's progress.

This documentation provides a clear record of the patient's clinical status and facilitates appropriate decision-making regarding further interventions.
