A client who weighs 132 lb receives a prescription for lorazepam 44 mcg/kg IV to be administer 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer?

(Enter numerical value only. If rounding is required, round to the nearest tenth.)
Answer and Explanation

The Correct Answer is ["1.3"]

Convert pounds to kilograms.

  • 1 pound = 0.453592 kilograms
  • 132 pounds * 0.453592 kg/pound = 59.87 kilograms

Step 2: Calculate the total dose in micrograms.

  • 44 micrograms/kilogram * 59.87 kilograms = 2635.08 micrograms

Step 3: Convert micrograms to milligrams.

  • 1 milligram = 1000 micrograms
  • 2635.08 micrograms / 1000 micrograms/milligram = 2.63508 milligrams

Step 4: Calculate the volume to be administered.

  • Concentration of lorazepam = 2 milligrams/milliliter
  • Volume = Dose / Concentration
  • Volume = 2.63508 milligrams / 2 milligrams/milliliter = 1.31754 milliliters

Therefore, the nurse should administer approximately 1.3 milliliters of the lorazepam solution.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"B"}}

Explanation

A. Select foods that are lower in caloric density
Effective: Choosing foods that are lower in caloric density (such as fruits, vegetables, lean proteins) can help the client feel fuller with fewer calories. This can support weight maintenance or even weight loss if that is the goal.

B. Increase exercise intensity
Effective: Increasing exercise intensity can help the client burn more calories, contributing to energy expenditure. This can assist in achieving energy balance, particularly if the client wants to maintain her current weight while consuming adequate calories.

C. Get up and walk at least once an hour at work
Effective: Incorporating regular physical activity throughout the day, such as walking breaks, helps increase energy expenditure. It also breaks up sedentary behavior, which is beneficial for overall health and can contribute to energy balance.

D. Add healthy foods to increase caloric intake
Ineffective: Adding healthy foods to increase caloric intake would likely lead to a positive energy balance (where intake exceeds expenditure), potentially causing weight gain. Since the goal is to maintain weight, increasing caloric intake, even with healthy foods, would not be effective.

E. Avoid food with high carbohydrate levels
Ineffective: Carbohydrates are an important source of energy. Avoiding foods with high carbohydrate levels could limit the client's energy intake, potentially leading to negative energy balance if not replaced adequately with other nutrients.
