Nursing Skills: Wound Care & IV Therapy

Reaching over a sterile field poses a risk of contamination due to potential transfer of microorganisms from the hands, arms, or clothing to the sterile area. Even if the item being placed is sterile, the act of reaching over compromises the integrity of the sterile environment, as it allows for the possibility of non-sterile surfaces coming into contact with sterile items. Maintaining a safe distance and minimizing movements over the field is crucial to preserving sterility.

REEDA is a mnemonic used to evaluate the status of perineal healing after childbirth. It specifically assesses five key components: Redness, which indicates inflammation; Edema, referring to swelling; Ecchymosis, or bruising; Discharge, which can signal infection; and Approximation, evaluating how well the edges of a wound are healing together. By examining these factors, healthcare providers can monitor recovery and identify potential complications in postpartum patients.

Slough is a type of necrotic tissue that appears as yellow, soft, and stringy material covering a wound bed. It consists of dead cells, bacteria, and other debris, which can impede healing if not removed. Unlike granulation tissue, which is healthy and promotes healing, slough indicates an unhealthy wound environment. Proper assessment and management are essential to facilitate healing and prevent infection.

Stage III pressure injury is characterized by full-thickness skin loss, where the damage extends through the dermis and into the subcutaneous fat layer. At this stage, the underlying structures such as bone, tendon, and muscle are not exposed, differentiating it from Stage IV injuries, which do show these deeper tissues. The visible subcutaneous fat indicates a significant level of tissue damage, but the absence of exposed bone or muscle means that the injury has not progressed to the most severe stage.

The symptoms described—redness, warmth, swelling, and a palpable cord along the vein—are indicative of phlebitis, which is inflammation of the vein. This condition often arises from irritation due to the IV catheter or the infused solution. Infiltration involves fluid leaking into surrounding tissues without inflammation, while extravasation refers to the leakage of irritant substances causing tissue damage. An air embolism presents with different symptoms related to air entering the bloodstream. Thus, the combination of these signs strongly points to phlebitis as the underlying complication.

Before administering any medication, especially via IV, it is crucial to ensure patient safety by verifying the medication details and patient identity. This step minimizes the risk of medication errors, such as incorrect dosing or administering the wrong drug. Using two identifiers, such as the patient's name and date of birth, confirms that the right patient receives the right medication at the right time. This practice is a fundamental aspect of safe nursing care and is essential for preventing adverse effects and ensuring effective treatment.

Airborne precautions are necessary for patients with active pulmonary tuberculosis because the bacteria can be transmitted through tiny droplets that remain suspended in the air for extended periods. These droplets can be inhaled by individuals in the vicinity, posing a risk of infection. To prevent this transmission, healthcare providers must wear N95 respirators or equivalent masks, and patients should be placed in negative pressure rooms to contain the airborne pathogens. This approach effectively reduces the risk of spreading tuberculosis to others in the healthcare setting.

To calculate the flow rate in drops per minute, first determine the total volume to be infused (1,000 mL) and the infusion time (8 hours). Convert 8 hours to minutes (8 × 60 = 480 minutes). Next, divide the total volume by the infusion time to find the flow rate in mL/min (1,000 mL / 480 min ≈ 2.08 mL/min). Finally, convert this to drops per minute using the drop factor (2.08 mL/min × 15 gtt/mL = 31.2 gtt/min), rounding down gives approximately 31 gtt/min.
