Which of the following interventions is considered a priority when treating a patient who presents with septic shock?
obtaining wound and blood
removing or controlling potentially infected sources
initiation of an intravenous line and fluid
drawing blood for hematology and chemistry studies
The Correct Answer is C
Septic shock is a life-threatening condition characterized by severe infection, systemic inflammation, and inadequate tissue perfusion. In this critical situation, one of the initial priorities is to restore intravascular volume and improve tissue perfusion. Initiation of an intravenous line allows for the administration of fluids and other necessary medications to support the patient's hemodynamic stability.
While the other interventions mentioned are also important components of septic shock management, the immediate priority is to address hypotension and tissue hypoperfusion through fluid resuscitation:
A. Obtaining wound and blood cultures in (option A) is incorrect because: Cultures are important to identify the source and causative organisms of the infection. However, fluid resuscitation should take priority over obtaining cultures, as it is necessary to stabilize the patient's hemodynamics.
B. Removing or controlling potentially infected sources in (option B) is incorrect because: Identifying and controlling the source of infection is crucial in septic shock management to prevent further progression. However, initiating fluid resuscitation is more time-sensitive and should be prioritized.
D. Drawing blood for hematology and chemistry studies in (option D) is incorrect because Laboratory studies are important for evaluating organ function and guiding treatment. However, the immediate focus should be on fluid resuscitation to address the underlying hypoperfusion and stabilize the patient's condition.
Therefore, the intervention considered a priority when treating a patient who presents with septic shock is the initiation of an intravenous line and fluid administration to restore intravascular volume and improve tissue perfusion.

Correct Answer is A
Explanation
Premature ventricular contractions (PVCs) are abnormal heart rhythms originating from the ventricles. They can be triggered by various factors, including irritation or stimulation of the airway during suctioning.
In this situation, the priority is to ensure adequate oxygenation and ventilation for the patient. Stopping the suctioning procedure and providing ventilatory support with 100% oxygen helps maintain oxygen levels and minimizes further cardiac dysrhythmias.
B. Check the patient's potassium level in (option B) is incorrect because While electrolyte imbalances, including low potassium levels (hypokalemia), can contribute to cardiac dysrhythmias, checking the potassium level is not the immediate priority when PVCs occur during suctioning.
C. Give prescribed PRN antidysrhythmic medications in (option C) is incorrect because: Administering antidysrhythmic medications without further assessment or evaluation may not be appropriate in this situation.
D. Decrease the suction pressure to 80 mm Hg in (option D) is incorrect because: While adjusting suction pressure may help prevent further irritation, it is not the initial priority when PVCs are present during suctioning.
E. Documenting the dysrhythmia in the patient's chart in (option E) is incorrect because: Documentation is important but should not be the initial action when a patient experiences PVCs during suctioning. Patient safety and immediate intervention take precedence.
Therefore, when PVCs occur during suctioning, the nurse should stop the procedure, provide ventilatory support with 100% oxygen, and assess the patient's response to intervention.

Doseinmcg/min=2mcg/kg/min×60kg=120mcg/min
Convert this to mg/min since the concentration is in mg:
120mcg/min=0.12mg/min120 \text{ mcg/min} = 0.12 \text{ mg/min}120mcg/min=0.12mg/min
-
Determine the concentration of Dopamine:
- Total amount of Dopamine: 200 mg in 250 mL of saline
- Concentration:
Concentration=200mg250mL=0.8mg/mL\text{Concentration} = \frac{200 \text{ mg}}{250 \text{ mL}} = 0.8 \text{ mg/mL}Concentration=250mL200mg=0.8mg/mL
-
Calculate the pump rate in mL/min:
To find the rate in mL/min needed to deliver 0.12 mg/min:
Pumprate=Desireddose(mg/min)Concentration(mg/mL)\text{Pump rate} = \frac{\text{Desired dose (mg/min)}}{\text{Concentration (mg/mL)}}Pumprate=Concentration(mg/mL)Desireddose(mg/min)
Pumprate=0.12mg/min0.8mg/mL=0.15mL/min\text{Pump rate} = \frac{0.12 \text{ mg/min}}{0.8 \text{ mg/mL}} = 0.15 \text{ mL/min}Pumprate=0.8mg/mL0.12mg/min=0.15mL/min
-
Convert the pump rate to mL/hour:
Multiply by 60 to convert from mL/min to mL/hour:
Pumprate=0.15mL/min×60min/hour=9mL/hour\text{Pump rate} = 0.15 \text{ mL/min} \times 60 \text{ min/hour} = 9 \text{ mL/hour}Pumprate=0.15mL/min×60min/hour=9mL/hour
So, you should set the pump to deliver Dopamine at a rate of 9 mL/hour.
