A nurse is caring for a client who presents with hyperthermia.
Which intervention should the nurse implement?

Choice C rationale

Hyperthermia often results in significant insensible fluid loss and dehydration, especially if caused by environmental factors or increased metabolic activity. Administering intravenous fluids is a critical intervention to restore intravascular volume, support cardiovascular stability, and promote cooling through improved peripheral perfusion. Hydration also helps maintain renal function, which can be compromised by myoglobinuria if muscle breakdown occurs. Normal saline or lactated Ringer's are typically used to correct these deficits and assist in lowering core temperature.

Choice A rationale

Applying a heating pad to the extremities is contraindicated in hyperthermia as it would further increase the patient's core body temperature. The goal of hyperthermia management is to facilitate heat loss, not heat gain. Heating the skin can also cause peripheral vasodilation that might lead to a drop in blood pressure if the patient is already dehydrated. Instead, cooling blankets or tepid sponges should be used to encourage heat dissipation through conduction and evaporation.

Choice B rationale

While antipyretics are used for infectious fevers, they are often insufficient or completely ineffective for environmental or drug induced hyperthermia. In cases of heat stroke or malignant hyperthermia, the underlying cause is not a change in the hypothalamic set point but an inability to lose heat or an excessive production of heat. Waiting for these medications to work without implementing active cooling measures can result in a dangerous delay in treatment, allowing the temperature to reach lethal levels.

Choice D rationale

Moving a client to a warm environment is the opposite of the required intervention. A patient with hyperthermia should be moved to a cool, shaded, or air conditioned environment to stop the external heat load. Keeping the patient in a warm area prevents the body from losing heat to the surroundings through radiation and convection. Effective management requires a temperature gradient where the environment is cooler than the body to facilitate the movement of heat away from the patient. .

Choice A rationale

Diarrhea is not a primary or life-threatening complication associated with medications that stimulate platelet production, such as oprelvekin or thrombopoietin receptor agonists. While gastrointestinal upset can occur with many medications, it does not represent the significant physiological risks targeted by nursing surveillance in this specific therapy. The focus of monitoring for these agents is centered on fluid balance and vascular integrity, as these drugs significantly impact intravascular osmotic pressure and the coagulation cascade through increased cellular production.

Choice B rationale

Nausea and vomiting are common side effects of many systemic therapies but are not considered the most critical or specific complications of platelet-stimulating agents. These symptoms are generally managed with antiemetics and do not typically require the cessation of therapy. When managing a patient on oprelvekin, the nurse prioritizes monitoring for systemic inflammatory responses and fluid retention over mild gastrointestinal distress, as the latter does not usually lead to long-term morbidity or acute cardiovascular collapse in this context.

Choice C rationale

Stimulating the production of platelets, or thrombopoiesis, carries a significant risk of inducing a prothrombotic state where blood clots may form. When the platelet count rises rapidly or exceeds the normal range of 150,000 to 450,000 cells/uL, the risk for deep vein thrombosis, pulmonary embolism, or myocardial infarction increases. The nurse must assess for signs of vascular occlusion, including localized edema, redness, and sudden chest pain, as the increased cell density enhances blood viscosity and clotting.

Choice D rationale

Bone fractures are not a typical complication of platelet-stimulating therapy. While some colony-stimulating factors can cause bone pain due to the expansion of bone marrow, they do not generally lead to acute structural failure or pathological fractures. Bone marrow stimulation is a physiological process that occurs within the medullary cavity and, while uncomfortable, does not degrade the mineral density of the cortical bone. Nursing care focuses on pain management rather than fall precautions related to skeletal fragility in these patients.

Choice E rationale

Pulmonary edema is a severe complication specifically linked to oprelvekin therapy due to its tendency to cause sodium and water retention. The resulting expansion of plasma volume increases hydrostatic pressure within the pulmonary capillaries, leading to fluid shifting into the alveoli. The nurse must monitor for dyspnea, crackles upon auscultation, and decreased oxygen saturation. This fluid shift can lead to acute respiratory distress syndrome, making frequent cardiovascular and respiratory assessments essential for early detection of fluid overload.
