The nurse is assessing clients in the emergency department. Which client is at highest risk for developing septic shock?

Choice A reason: Marking the expiration date on a calendar is a proactive and correct safety measure. Epinephrine loses its potency over time, and a patient must ensure the medication is current to be effective during a life threatening anaphylactic event where every second is critical for survival.

Choice B reason: This statement is incorrect and indicates a need for further teaching. Epinephrine is a short acting medication that provides temporary relief from airway constriction and vasodilation. A biphasic reaction can occur, where symptoms return after the initial dose wears off, requiring immediate professional medical observation and stabilization.

Choice C reason: Epinephrine autoinjectors are designed for emergency use and can be effectively administered through most clothing, such as jeans or leggings. This design allows for rapid delivery of the medication without the delay of undressing, which is essential during a rapidly progressing allergic reaction.

Choice D reason: Patients are often prescribed a twin pack because a single dose may not be sufficient to reverse severe anaphylaxis, or a second dose may be needed if emergency services are delayed. Carrying two injectors ensures the patient has a backup for refractory symptoms or mechanical failure.

Choice A reason: Septic shock is defined by persistent hypotension that does not respond to intravenous fluid resuscitation, requiring vasopressors to maintain a mean arterial pressure ≥ 65 mm Hg. A drop in blood pressure to 70/34 despite a bolus is a hallmark indicator of the transition to shock.

Choice B reason: A decrease in white blood cell count toward the normal range (5,000 to 10,000/mm3) generally suggests an improving inflammatory or infectious state. In severe sepsis, a very low WBC (leukopenia) might be seen, but a shift from 11,000 to 9,500 is not a primary indicator of shock.

Choice C reason: While an increase in lactate suggests worsening tissue perfusion, a value of 1.8 mmol/L is still within the normal range (typically < 2.0 mmol/L). In septic shock, one would expect the lactate to rise significantly, usually above 2.0 mmol/L, as anaerobic metabolism becomes more widespread.

Choice D reason: A urine output of 300 mL following a fluid bolus is an excellent clinical sign, suggesting that the kidneys are being well perfused and are responding to the volume expansion. This finding would indicate an improvement in hemodynamic status rather than a progression toward shock.
