 Administer Dopamine at 10 mcg/kg/min. The pharmacy provides dopamine 800 mg in 250 mL of D5W. Your client weights 85.3 kg. How many mL/hr are you to set the infusion pump? (Round answer to nearest whole number)
Answer and Explanation

The Correct Answer is ["16"]

Step 1: Determine client’s dose in mcg/min

10 mcg/kg/min×85.3 kg=853 mcg/min

Step 2: Convert mcg/min to mg/hr

  • 853 mcg/min=0.853 mg/min

  • Per hour:

0.853 mg/min×60 min/hr=51.18 mg/hr

Step 3: Determine concentration of dopamine solution

  • 800 mg in 250 mL → 800 mg250 mL=3.2 mg/mL

Step 4: Calculate infusion rate in mL/hr

51.18 mg/hr3.2 mg/mL=15.99 mL/hr

Step 5: Round to nearest whole number

≈16 mL/hr

Correct Answer is ["18"]

Explanation

To calculate the IV pump setting, first convert the patient's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The patient weighs 195 pounds, which is approximately 88.64 kilograms (195 / 2.2). Next, calculate the total units of Heparin needed per hour by multiplying the patient's weight in kilograms by the dosage ordered: 20 units/kg/hr. So, 88.64 kg * 20 units/kg/hr equals 1,772.8 units/hr. Now, determine how many milliliters per hour this dosage requires. Since the premixed bag contains 25,000 units in 250 ml, there are 100 units per ml (25,000 units / 250 ml). Finally, divide the total units needed per hour by the concentration to find the volume needed per hour: 1,772.8 units/hr / 100 units/ml equals 17.728 ml/hr. Rounded to the nearest whole number, the IV pump should be set to 18 ml/hr.

Correct Answer is B

Explanation

A. Blood cultures can identify causative organisms but are not definitive for meningitis.
B. Lumbar puncture is the definitive test for meningitis, as it allows for analysis of cerebrospinal fluid to confirm the diagnosis and identify the causative organism.
C. MRI can provide imaging of the brain but cannot definitively diagnose meningitis.
D. CT scan is useful for imaging but does not provide a definitive diagnosis of meningitis.
