The physician prescribes levofloxacin 300 mg IV every 6 hours for a client diagnosed with sepsis.

The client weighs 43.5 kg. The nursing drug guide recommends a maximum of 5 - 7.5 mg/kg/dose.

What is the maximum safe dose for this client in mg/dose? Round answer to the nearest hundredth.

Nursing prioritization relies on the ABC framework and identifying the most immediate threat to life. Knowledge of electrolyte imbalances and cardiac conduction must be applied here to recognize that severe hyperkalemia poses an imminent risk of lethal cardiac arrhythmias.

Choice A rationale

A low grade fever of 38.2 C on the first postoperative day is common due to the inflammatory response or atelectasis. While it requires monitoring and lung expansion exercises, it is not an immediate life threat.

Choice B rationale

Severe abdominal pain and nausea are classic symptoms of acute pancreatitis. While the patient is in significant distress and needs analgesia, this presentation is expected for the diagnosis and is second to cardiovascular instability.

Choice C rationale

Confusion and asterixis in cirrhosis indicate hepatic encephalopathy due to elevated ammonia. Normal ammonia is 15 to 45 mcg/dL. This requires treatment with lactulose but is less immediately fatal than a cardiac arrest.

Choice D rationale

A potassium level of 6.8 mEq/L is critically high, as the normal range is 3.5 to 5.0 mEq/L. Peaked T waves indicate myocardial irritability, which can progress rapidly to ventricular fibrillation or asystole, requiring emergent intervention..

Sepsis requires a focused assessment of systemic perfusion and the inflammatory response. Knowledge of the Sequential Organ Failure Assessment criteria is necessary. The nurse must prioritize assessments that reflect respiratory function, renal perfusion, and peripheral microvascular status to detect early deterioration.

Choice A rationale

Sepsis often leads to increased capillary permeability and acute lung injury. Assessing breath sounds allows the nurse to detect adventitious sounds like crackles, which may indicate the development of pulmonary edema or progressing respiratory distress or infection.

Choice B rationale

Urine output is a primary indicator of organ perfusion. In sepsis, decreased output less than 0.5 mL per kg per hr suggests inadequate renal blood flow or acute kidney injury resulting from systemic hypotension and inflammatory damage.

Choice C rationale

While glucose levels can fluctuate during the stress response of sepsis, it is not a primary component of a focused sepsis assessment compared to hemodynamic markers. Hyperglycemia is common but does not specifically define the septic state.

Choice D rationale

Skin temperature and capillary refill provide information about peripheral perfusion. In early sepsis, skin may be warm due to vasodilation, while late sepsis often presents with cool, clammy skin as the body shunts blood to organs.

Choice E rationale

The date of the last bowel movement is a part of a general gastrointestinal assessment but is not a priority in a focused sepsis evaluation. It does not provide immediate data regarding systemic inflammatory response or perfusion..
