The Provider orders an IV weight-based medication to be infused at 4 mcg/kg/min. The patient weighs 198 lbs. You are supplied with a bag of the IV medication that reads 250mg/250 ml. How many mL/hr will you administer?

NOTE

  • DO NOT write the unit/s of measurement
  • DO NOT round your answer
Answer and Explanation

The Correct Answer is ["21.6"]

  Convert pounds to kilograms:

  • 198 lbs / 2.2 lbs/kg = 90 kg

  Calculate the medication dose in mcg/min:

  • 90 kg  4 mcg/kg/min = 360 mcg/min

  Convert mcg/min to mg/hr:

  • 360 mcg/min  60 min/hr = 21600 mcg/hr
  • 21600 mcg/hr / 1000 mcg/mg = 21.6 mg/hr

  Determine the medication concentration:

  • 250 mg / 250 mL = 1 mg/mL

  Calculate the infusion rate in mL/hr:

  • 21.6 mg/hr / 1 mg/mL = 21.6 mL/hr

Correct Answer is C

Explanation

A. Low levels of both HDL and LDL cholesterol is not desirable as low levels of HDL cholesterol are associated with a higher risk for heart disease.
B. Low levels of high-density lipoprotein (HDL cholesterol) are undesirable because HDL helps remove excess cholesterol from the bloodstream, and lower levels increase the risk of cardiovascular disease.
C. Low levels of low-density lipoprotein (LDL cholesterol) is the most desirable situation. Lower LDL levels reduce the risk of atherosclerosis and heart disease, making it important to lower these levels in patients with coronary artery disease.
D. Hypocholesterolemia (abnormally low cholesterol levels) is not typically targeted as a treatment goal and can be harmful in some situations, as cholesterol is essential for many bodily functions.

Correct Answer is A

Explanation

B. A concentrated calorie formula may not be appropriate for this patient as it could lead to hyperglycemia due to increased glucose intake.
C. Whole proteins and glucose polymers might increase the glucose load and exacerbate poor blood sugar control.
D. While low sodium is important for many conditions, it is not the primary concern for managing poorly controlled diabetes mellitus in the context of enteral nutrition.
