Four hours after major abdominal surgery, the nurse notes that the patient does not have any bowel sounds. What is the appropriate action for the nurse to take?

Choice A rationale:

STAT orders are urgent and require immediate action. They are typically used for life-threatening situations or when a rapid response is needed to prevent serious harm. In this case, an EKG is important for patients admitted to the cardiac unit, but it is not necessarily an urgent procedure that requires immediate action in all cases.

STAT orders are often given verbally or over the phone, and they are typically written in all capital letters with the word "STAT" prominently displayed.

Examples of STAT orders include medications for cardiac arrest, intubation for respiratory distress, or emergency surgery for a ruptured appendix.

Choice B rationale:

PRN orders are "as needed" orders, meaning they are only carried out when a specific condition or symptom arises. They are not routinely implemented for all patients in a particular unit or setting.

PRN orders allow for flexibility in treatment plans and can help to manage pain, nausea, anxiety, or other symptoms that may fluctuate over time.

Examples of PRN orders include pain medication, anti-nausea medication, or sedatives.

Choice C rationale:

One-time orders are administered only once and are not repeated. They are often used for procedures, diagnostic tests, or medications that are not required on an ongoing basis.

In this case, an EKG is typically a one-time order for patients outside of the cardiac unit, but it becomes a standing order for patients admitted to the cardiac unit due to the increased importance of cardiac monitoring in this setting.

Examples of one-time orders include a chest X-ray, a blood draw, or a dose of antibiotics.

Choice D rationale:

Standing orders are routine orders that are implemented for all patients in a particular unit or setting, unless otherwise specified. They are designed to provide consistent and standardized care, and they often reflect best practices or guidelines for a specific patient population.

Standing orders can help to streamline care processes, reduce the need for individual orders, and ensure that patients receive necessary treatments or interventions without delay.

In this case, the standing order for an EKG upon admission to the cardiac unit ensures that all patients receive this important cardiac assessment, even if the ordering provider does not specifically write an order for it.

Other examples of standing orders in a cardiac unit might include daily weights, regular vital sign checks, or administration of cardiac medications.

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.
