Dopamine 5 mcg/kg/minute IV is prescribed for a client who weighs 132 pounds. The pharmacy dispenses a 500 mL IV solution of 0.9% normal saline with dopamine 1600 mg. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth)
The Correct Answer is ["5.6"]
Convert pounds to kg 1kg= 2.2 pounds 132pounds= 132/2.2=60kg
Desired dose per minute= 5 mcg/kg= 560=300mcg/min Desired dose per hour= 300mcg60mins= 18000mcg Available dose= 1600mg/500ml
1mg=1000mcg
Available dose = 1600000mcg/500ml Infusion rate:
1600000mcg=500ml 18000mcg=18000500/1600000
= 5.625 mL/hour
Rounded to the nearest tenth: 5.6 ml/hour

Correct Answer is ["B","C","D"]
Explanation
A. Encouraging the nurse to flush the tube with more water is not mentioned as a necessary action based on the information provided. Flushing with water is typically done to ensure the tube
remains patent and to prevent medication interactions within the tube, but the scenario does not indicate that the nurse failed to do this or that there was an issue with tube patency.
B. Instructing the nurse to administer each medication separately is correct. This is important to prevent drug interactions within the tube and to ensure accurate dosing. Administering
medications separately allows for proper absorption and can prevent complications such as clogging of the tube.
C. Adding the liquid volumes when documenting fluid intake is correct. It is essential to account for all sources of fluid intake to maintain accurate fluid balance records. Medications
administered through a gastrostomy tube contribute to the patient's overall fluid intake and must be included in the documentation.
D. Confirming that the nurse determined the amount of gastric residual is correct. This is a critical step to ensure that the patient is tolerating the feedings and to prevent complications such as
aspiration. Gastric residual volume can indicate if the patient's digestive system is processing the feeding appropriately.
E. Advising the nurse to use the plunger when giving medications is not necessary in this context. The use of a plunger can be appropriate in some situations, but the scenario does not provide enough information to suggest that the nurse had difficulty administering the medications that would require the use of a plunger. Additionally, using a plunger can increase the risk of tube
damage or patient discomfort.
Correct Answer is B
Explanation
A. Support stockings may help with peripheral edema, but they do not address the underlying issue of hypoalbuminemia and its consequences.
B. Adequate protein intake is crucial for increasing serum albumin levels, which can help reduce edema and improve the client's nutritional status. This intervention addresses the root cause of
the client's symptoms.
C. Evaluating the patency of the AV graft is important for long-term planning of hemodialysis access, but it is not the immediate priority given the client's current nutritional status and symptoms.
D. Fluid restriction is important in managing peritoneal dialysis patients, but it does not address the immediate concern of hypoalbuminemia and its effects on the client's health.
