A client with suspected pulmonary embolism has chronic kidney disease and recent contrast-induced nephropathy.
Which diagnostic test is most appropriate?

Post-operative skin graft care focuses on maximizing graft take by reducing edema and preventing shearing. Knowledge of tissue perfusion and fluid dynamics is necessary to prioritize actions that minimize swelling, which can lift the graft from the bed.

Choice A rationale

Elevating the affected extremity reduces edema at the graft site by promoting venous return. Excessive swelling can separate the new graft from the underlying vascular bed, preventing necessary revascularization and leading to graft failure or necrosis.

Choice B rationale

Inspecting the graft site is important, but the nurse should generally not disturb the initial surgical dressing. Frequent inspection increases the risk of shearing or dislodging the delicate graft before it has successfully adhered to the site.

Choice C rationale

Ensuring the patient does not lie on the graft is a standard intervention to prevent pressure and shearing. However, in the presence of noted edema, elevation is the priority action to ensure the graft remains viable.

Choice D rationale

Administering analgesics addresses the pain level of 6/10, which is important for comfort. However, pain is expected, whereas reducing edema through elevation is functionally more critical to the physiological success and survival of the graft.

Dexamethasone is a potent corticosteroid used to reduce cerebral edema in brain tumor patients. Prioritizing care requires identifying life-threatening neurological changes or severe medication side effects, applying knowledge of intracranial pressure, glucose metabolism, and the hierarchy of clinical needs.

Choice A rationale

Acute loss of orientation to self indicates a significant decline in neurological status or increased intracranial pressure. This is a medical emergency requiring immediate intervention to prevent brain herniation, outweighing stable physical side effects of steroid therapy.

Choice B rationale

Weight gain is a common side effect of long-term dexamethasone use due to fluid retention and increased appetite. While it requires monitoring, it is an expected systemic effect and does not represent an immediate life-threatening crisis.

Choice C rationale

Insomnia is a known side effect of corticosteroids because they can interfere with the circadian rhythm and stimulate the central nervous system. It affects the client's comfort but does not indicate immediate physiological or neurological compromise.

Choice D rationale

Glucocorticoids cause hyperglycemia; 350 mg/dL is high compared to the normal fasting range of 70 to 100 mg/dL. While it requires insulin or dosage adjustment, it is less urgent than an acute neurological deficit..
