A nurse is caring for a client who has a cardiopulmonary arrest.
The nurse anticipates the emergency response team will administer which of the following medications if the client's restored rhythm is symptomatic bradycardia?

Evaluating post surgical and post pulmonary embolism recovery requires assessing functional mobility, respiratory stability, and wound healing. Knowledge of normal rehabilitation milestones and the resolution of thromboembolic symptoms is necessary to determine if the client is meeting expected outcomes.

Choice A rationale

Independent performance of activities of daily living indicates restored functional capacity and successful rehabilitation after surgery. It demonstrates that the client has regained sufficient strength and coordination to manage self care tasks without exhausting their cardiovascular reserves.

Choice B rationale

Unintentional weight loss of 27 lbs within six weeks is an abnormal finding that suggests underlying pathology, malnutrition, or chronic illness. It does not indicate improvement and instead necessitates further medical investigation to rule out complications.

Choice C rationale

Transitioning to independent walking with a cane shows progress in gait stability and weight bearing tolerance on the prosthetic joint. This movement away from more restrictive assistive devices like walkers is a positive indicator of recovery.

Choice D rationale

Significant bruising and discoloration are concerning signs, potentially indicating a bleeding disorder or complications from ongoing anticoagulation therapy. This finding represents a setback or a new problem rather than a sign of successful clinical improvement.

Choice E rationale

Increased pain with movement in the surgical area suggests potential complications such as infection, prosthesis loosening, or hip dislocation. Expected progress involves a steady decrease in pain levels as the surgical site heals over the weeks.

Choice F rationale

The absence of shortness of breath and chest pain indicates that the pulmonary embolism has resolved and gas exchange is stable. This respiratory comfort suggests that pulmonary perfusion has been restored and the lungs are healing.

Choice G rationale

An oxygen saturation of 95 is within the normal range of 95 to 100 percent. This indicates adequate arterial oxygenation and demonstrates that the client no longer requires supplemental oxygen to maintain systemic tissue perfusion after recovery.

Choice H rationale

A visible hairline scar without redness, swelling, or drainage confirms successful primary intention healing of the surgical incision. This indicates that the skin integrity is restored and the risk of localized or systemic infection is decreasing.

This scenario involves metabolic complications following chemotherapy for high-grade malignancies. Knowledge of intracellular electrolyte release, nucleic acid breakdown, and the resulting renal and systemic impacts is required to identify the specific oncological emergency occurring during rapid cell lysis.

Choice A rationale

Gastric ulcers cause abdominal pain and potential bleeding but do not account for a rapid increase in serum uric acid. Uric acid elevation is a systemic metabolic event related to DNA breakdown, whereas ulcers are localized mucosal erosions.

Choice B rationale

Tumor lysis syndrome occurs when chemotherapy causes rapid destruction of malignant cells, releasing intracellular contents. This leads to hyperuricemia, hyperkalemia, and hyperphosphatemia. High uric acid levels (above 6 mg/dL) can cause acute renal failure due to crystal formation.

Choice C rationale

While acute kidney injury may result from tumor lysis syndrome, it is a secondary consequence of the metabolic derangement. The primary diagnosis explaining the constellation of rapid uric acid rise and chemotherapy timing is the lysis syndrome.

Choice D rationale

Gastroenteritis causes nausea and abdominal pain but does not explain the significant metabolic shift of elevated uric acid. It is typically an infectious or inflammatory condition of the digestive tract, not a systemic response to cytotoxic therapy.
