Ordered: Dopamine2mcg/kg/min In Stock: 200mg in 250mL Saline Patients weight: 60kg What rate would you set the pump to deliver the ordered medication? (Document to the nearest whole number)
The Correct Answer is ["9"]
-
Dose in mcg/min=2 mcg/kg/min×60 kg=120 mcg/min
Convert this to mg/min since the concentration is in mg:
120 mcg/min=0.12 mg/min120 \text{ mcg/min} = 0.12 \text{ mg/min}120 mcg/min=0.12 mg/min
-
Determine the concentration of Dopamine:
- Total amount of Dopamine: 200 mg in 250 mL of saline
- Concentration:
Concentration=200 mg250 mL=0.8 mg/mL\text{Concentration} = \frac{200 \text{ mg}}{250 \text{ mL}} = 0.8 \text{ mg/mL}Concentration=250 mL200 mg=0.8 mg/mL
-
Calculate the pump rate in mL/min:
To find the rate in mL/min needed to deliver 0.12 mg/min:
Pump rate=Desired dose (mg/min)Concentration (mg/mL)\text{Pump rate} = \frac{\text{Desired dose (mg/min)}}{\text{Concentration (mg/mL)}}Pump rate=Concentration (mg/mL)Desired dose (mg/min)
Pump rate=0.12 mg/min0.8 mg/mL=0.15 mL/min\text{Pump rate} = \frac{0.12 \text{ mg/min}}{0.8 \text{ mg/mL}} = 0.15 \text{ mL/min}Pump rate=0.8 mg/mL0.12 mg/min=0.15 mL/min
-
Convert the pump rate to mL/hour:
Multiply by 60 to convert from mL/min to mL/hour:
Pump rate=0.15 mL/min×60 min/hour=9 mL/hour\text{Pump rate} = 0.15 \text{ mL/min} \times 60 \text{ min/hour} = 9 \text{ mL/hour}Pump rate=0.15 mL/min×60 min/hour=9 mL/hour
So, you should set the pump to deliver Dopamine at a rate of 9 mL/hour.

Correct Answer is C
Explanation
Urine output is an essential indicator of renal perfusion and overall fluid status. In a patient in shock, maintaining an adequate urine output is a crucial goal of fluid resuscitation. A urine output of 0.5 to 1 mL/kg/hour is generally considered adequate in adults. The given value of 35 ml over the last hour suggests that the patient is producing urine, which indicates that fluid resuscitation is effective in restoring perfusion to the kidneys.
A. The patient's mean arterial pressure (MAP) is 50 mm Hg in (option A) is incorrect because While mean arterial pressure is an important hemodynamic parameter, a single value alone may not provide a comprehensive assessment of the patient's response to fluid resuscitation.
B. The patient's GCS score is 9 in (option B) is incorrect because The Glasgow Coma Scale (GCS) assesses the level of consciousness and neurological function but does not directly reflect fluid resuscitation effectiveness.
D. The patient's hemoglobin is within normal limits: (option D) is incorrect because Haemoglobin levels are important for assessing oxygen-carrying capacity but do not directly indicate the effectiveness of fluid resuscitation.
Therefore, the nurse can evaluate that fluid resuscitation for a 70 kg patient in shock is effective by observing a urine output of 35 ml over the last hour.
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.
