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. Excessive fluid losses may lead to dehydration, but this is not typically a primary concern for patients with pulmonary alterations unless there is significant vomiting, diarrhea, or blood loss.
B. Hemodilution is not a common concern in patients with pulmonary alterations. Hypernatremia typically occurs with fluid loss or inadequate fluid intake, but it is not a direct concern related to pulmonary issues.
C. Fluid volume excess can lead to right-sided heart failure in patients with pulmonary alterations. If fluid accumulates, it can worsen pulmonary symptoms and increase the workload on the heart, potentially leading to right-sided heart failure.
D. Fluid retention with tachypnea is not typically a direct cause of fluid retention. While tachypnea is associated with respiratory distress, fluid retention is more closely linked to heart failure or kidney dysfunction.

Correct Answer is C

Explanation

A. Sodium Bicarbonate is incorrect as it is not a first-line treatment for VF. It may be considered in cases of severe acidosis or hyperkalemia.
B. Amiodarone is incorrect as it is used as an antiarrhythmic, but epinephrine is administered first during cardiac arrest to increase perfusion.
C. Epinephrine is correct because it is the first-line drug given in ventricular fibrillation that persists after defibrillation. It increases coronary and cerebral perfusion and enhances the effectiveness of subsequent defibrillation attempts.
D. Lidocaine is incorrect as it is an antiarrhythmic that may be considered after epinephrine and amiodarone, but it is not the first choice.
