Dopamine hydrochloride IV at 2 mcg/kg/minute is prescribed to promote renal perfusion for a client weighing 198 lbs. The pharmacy sends a pre-mixed bag of dopamine containing 400 mg in 250 mL dextrose 5% in water (DSW). An IV pump is available that provides a precision infusion rate to a tenth of a mL. The nurse should set the IV pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["6.8"]
Converting the weight to kg:
Client weight = 198 lbs 1 lb = 0.453592 kg
Client weight in kg = 198 lbs 0.453592 kg/lb = 90.7 kg
Calculating the desired dopamine infusion rate:
Dose = 2 mcg/kg/minute Client weight = 90.7 kg
Desired infusion rate = Dose Client weight = 2 mcg/kg/minute 90.7 kg = 181.4 mcg/minute
Determining the dopamine concentration in the bag:
Dopamine amount = 400 mg Bag volume = 250 mL
Dopamine concentration = Dopamine amount / Bag volume = 400 mg / 250 mL = 1.6 mg/mL
Convert mg/mL to mcg/mL: 1.6 mg/mL 1000 mcg/mg = 1600 mcg/mL
Calculating the rate in mL/minute:
Desired infusion rate = 181.4 mcg/minute Dopamine concentration = 1600 mcg/mL
Rate (mL/minute) = Desired infusion rate (mcg/minute) / Dopamine concentration (mcg/mL)
Rate = 181.4 mcg/minute / 1600 mcg/mL = 0.1134 mL/minute
Converting the rate to mL/hour:
Rate (mL/minute) = 0.1134 mL/minute Conversion factor: 60 minutes/hour
Rate (mL/hour) = 0.1134 mL/minute 60 minutes/hour = 6.8 mL/hour (round to nearest tenth)
Therefore, the nurse should set the IV pump to deliver approximately 6.8 mL/hour.

Correct Answer is D
Explanation
A. A blood glucose level of 90 mg/dL is within the normal reference range of 74 to 106 mg/dL, so it is not a concern.
B. A potassium level of 4 mEq/L is also within the normal reference range of 3.5 to 5.0 mEq/L, so it does not need to be reported.
C. Although the hemoglobin level of 13 g/dL is below the reference range provided, it is not critically low and may not be urgent unless the patient has symptoms of anemia or other related issues.
D. A serum creatinine level of 5 mg/dL is significantly higher than the normal reference range of 0.5 to 1.1 mg/dL. This indicates renal impairment, which could affect the patient's ability to clear medications used during surgery and could lead to postoperative complications. Therefore, it is crucial to report this finding to the surgeon immediately.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C","dropdown-group-3":"D"}
Explanation
-
Short-term memory loss: While some degree of memory loss can be a normal part of aging, significant short-term memory loss in the context of elder mistreatment can indicate neglect or psychological abuse. It might reflect isolation or a lack of proper mental stimulation and care.
-
Pressure injuries: These are clear indicators of neglect. Pressure injuries, such as bedsores, occur when a person is not moved or repositioned regularly. They can suggest that the caregiver is not providing adequate care or attention to the client's physical needs.
-
Malnutrition: This is a strong sign of neglect. Malnutrition, evidenced by loss of subcutaneous fat and low body weight, indicates that the client is not receiving adequate nutrition. This could be due to neglect in providing food or a lack of attention to dietary needs, which is a form of mistreatment.
