A client presents with a surgical incision that is red, swollen, and warm to touch.
How should the nurse prioritize the hypothesis regarding the cause?

Choice A rationale

Maintaining a urine output of 30 to 50 mL per hour is the gold standard indicator that fluid resuscitation is effectively restoring organ perfusion. This volume suggests that the kidneys are receiving enough blood to maintain a normal glomerular filtration rate. In burn patients, adequate urine production confirms that the intravascular volume has been sufficiently replaced to overcome the massive fluid shifts and capillary leak syndrome that occur immediately following a significant thermal injury.

Choice B rationale

A heart rate greater than 120 beats per minute is usually an indicator of ongoing stress, pain, or hypovolemia rather than successful resuscitation. Tachycardia suggests that the heart is still working excessively hard to maintain cardiac output in the face of low blood volume. A successful resuscitation should ideally lead to a stabilization of the heart rate towards a more normal range, typically below 110 beats per minute, as the intravascular volume is restored and sympathetic drive decreases.

Choice C rationale

While some weight gain is expected during the acute phase of burn care due to the administration of large volumes of crystalloid fluids and subsequent edema, an increase of 5 percent is not a specific indicator of successful resuscitation. Excessive weight gain can actually signal fluid overload or third-spacing rather than effective intravascular volume replacement. The goal of resuscitation is to support vital organ function with the least amount of fluid necessary, avoiding complications like pulmonary edema.

Choice D rationale

Decreased peripheral pulses are a concerning sign that may indicate inadequate systemic perfusion or localized compartment syndrome due to circumferential burns and excessive edema. Successful fluid resuscitation should result in the maintenance or improvement of peripheral pulses, indicating that blood is reaching the distal extremities. If pulses are weakening, it suggests that the circulatory status is deteriorating or that fluid is accumulating in the interstitial spaces so severely that it is compressing the arterial flow.

Choice A rationale

While a family history of allergies can provide context regarding the patient's predisposition to hypersensitivity reactions like atopy or contact dermatitis, it is not the most critical assessment for ensuring current skin protection. The history explains why the reaction occurred but does not provide real-time data on the physiological status of the skin barrier. The nurse's immediate priority is the physical state of the skin to prevent complications that could arise during the acute phase of the illness.

Choice B rationale

Assessing the extent of itching and irritation is important for patient comfort and for determining the severity of the allergic response to urushiol. However, itching is a subjective symptom that describes the patient's distress rather than the actual structural integrity of the skin. While severe itching leads to scratching, which can damage the skin, the assessment of the broken skin itself is more critical for determining the risk of secondary bacterial invasion and the loss of protective function.

Choice C rationale

Identifying the presence of broken skin or infection is critical because the primary function of the skin is to act as a barrier against pathogens. Poison ivy causes vesicles that can rupture, creating portals of entry for bacteria like Staphylococcus aureus or Streptococcus pyogenes. If the skin is broken, its protective function is compromised, increasing the risk of cellulitis or impetigo. This assessment guides the need for topical or systemic antibiotics and specialized dressings to restore the barrier.

Choice D rationale

Assessing the application of topical steroids is part of evaluating the treatment plan but is not a direct assessment of the skin's protective function. Steroids work by reducing the inflammatory response and decreasing the immune-mediated damage to the skin, but the nurse must first know the state of the skin to apply them safely. Overuse of steroids can also lead to skin thinning or atrophy, so while relevant, it is secondary to identifying whether the physical barrier has been breached.
