The nurse is caring for a client diagnosed with rhabdomyolysis with an elevated myoglobin treated with intravenous fluid. Which finding by the nurse indicates the intervention was effective?
Decreased temperature
Increased blood pressure
Increased urine output
Decreased heart rate
The Correct Answer is C
Choice A reason: While a fever may be present in some cases of rhabdomyolysis due to systemic inflammation, a decrease in temperature is not the primary clinical indicator used to measure the effectiveness of the specific treatment for myoglobinuria or renal protection.
Choice B reason: Increased blood pressure might occur as a result of fluid resuscitation, but it is not the specific goal for treating rhabdomyolysis. Blood pressure is a general indicator of hemodynamic status rather than a specific measure of whether myoglobin is being cleared from the kidneys.
Choice C reason: In rhabdomyolysis, large amounts of myoglobin are released into the bloodstream, which can obstruct renal tubules and cause acute tubular necrosis. The goal of aggressive IV fluid therapy is to "flush" the kidneys. Increased urine output confirms that the myoglobin is being diluted and excreted effectively.
Choice D reason: A decreased heart rate may indicate that the patient’s fluid volume is being restored and the compensatory tachycardia is resolving. However, this is a secondary sign of hemodynamic stability and does not directly confirm the prevention of myoglobin-induced renal damage.

Correct Answer is D
Explanation
Choice A reason: Hemoglobin and hematocrit levels are indicators of the total red blood cell mass and oxygen carrying capacity. While these values are important to assess the severity of blood loss already sustained, they do not help identify the underlying coagulopathy causing the spontaneous bleeding from multiple unrelated sites.
Choice B reason: A STAT electrocardiogram is used to assess cardiac rhythm and identify myocardial ischemia or conduction abnormalities. While septic shock can place significant strain on the cardiovascular system, an EKG is not the priority diagnostic tool for a patient exhibiting signs of systemic, multi-site spontaneous hemorrhage.
Choice C reason: Monitoring the client’s temperature is a standard part of assessing a patient with sepsis to track the inflammatory response or the effectiveness of antibiotic therapy. However, thermoregulation assessment does not address the immediate life threatening risk associated with suspected disseminated intravascular coagulation and active bleeding.
Choice D reason: The clinical presentation of oozing from IV sites, bleeding gums, and hematuria in a septic patient is highly suggestive of disseminated intravascular coagulation. Checking the platelet count, Prothrombin Time, and International Normalized Ratio is the critical first step to confirm a consumption coagulopathy and guide blood product replacement.
Correct Answer is A
Explanation
Choice A reason: Burn dressing changes are notoriously painful due to the exposure of raw tissue and mechanical debridement. Pre-medicating the client 20 to 30 minutes prior to the procedure ensures therapeutic drug levels are reached, facilitating client cooperation and preventing the physiological stress response associated with severe pain.
Choice B reason: Removing the old dressing is a necessary step, but it must occur after pain management has been addressed. If the nurse removes the dressing without prior medication, the client may experience excruciating pain, making it difficult to complete the sterile portion of the procedure safely.
Choice C reason: Preparing equipment at the bedside is a logistical requirement for any procedure. While important for efficiency, it does not take priority over the ethical and clinical necessity of ensuring the client is comfortable and physiologically prepared for a painful intervention.
Choice D reason: Placing a sterile glove is one of the final steps in the actual dressing application process. It occurs long after the initial assessment, pain management, and removal of the old dressing. Proper sequencing ensures that the sterile field remains uncontaminated throughout the procedure.
