A 31-year-old male patient with burn injuries is admitted to the burn unit. Which priority does the nurse anticipate within the first 24 hours?

In a patient receiving mechanical ventilation, a high respiratory rate can indicate increased work of breathing and potential airway obstruction. COPD patients, in particular, may have excessive mucus production and airway inflammation, leading to mucus plugging and compromised airway clearance. Suctioning may be necessary to remove excessive secretions and maintain a patent airway.
A. The pulse oximeter shows a SpO2 of 90% in (option A) is incorrect because While a SpO2 of 90% is suboptimal and may require intervention, it does not specifically indicate the need for suctioning. Other interventions, such as adjusting oxygen delivery or ventilation settings, may be more appropriate.
B. The patient has not been suctioned for the last 6 hours in (option B) is incorrect because The duration since the last suctioning episode alone does not necessarily indicate the need for suctioning. The need for suctioning should be based on the patient's clinical presentation, such as signs of airway obstruction or excessive secretions.
D. The lungs have occasional audible expiratory wheezes in (option D) which is incorrect because Occasional audible expiratory wheezes may be common in patients with COPD and may not specifically indicate the need for suctioning. Wheezing is more commonly associated with narrowing of the airways, and suctioning is typically performed to clear secretions or maintain airway patency.
C. Therefore, in a COPD patient receiving mechanical ventilation, a high respiratory rate (C) is the assessment information that would indicate the need for suctioning to help remove excessive secretions and ensure a patent airway

1. 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

2. 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

3. 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

4. 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.
