The nurse is preparing a dose of 60 mcg of teriparatide. The medication is labeled "750 mcg/2.4 mL". How many ml. should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Answer and Explanation

The Correct Answer is ["0.2"]

Step-by-step Calculation:

  1. We need to find the volume (in mL) of teriparatide that contains the desired dose of 60 mcg.
  2. Set up the proportion: dose (mcg) / concentration (mcg/mL) = volume (mL)
  3. Fill in the known values:
    • Dose (mcg): 60 mcg (as given in the problem)
    • Concentration (mcg/mL): 750 mcg/2.4 mL (from the medication label)
  4. Solve for the volume:
    • Multiply both sides of the proportion by the concentration to isolate the volume on the left:
    • dose (mcg) = volume (mL) concentration (mcg/mL)
    • Substitute the known values:
    • 60 mcg = volume (mL) (750 mcg / 2.4 mL)
  5. Calculate the volume:
    • Divide both sides by the concentration to solve for the volume:
    • volume (mL) = 60 mcg / (750 mcg / 2.4 mL)
    • Simplify:
    • volume (mL) = (60 mcg 2.4 mL) / 750 mcg
    • volume (mL) = 0.192 mL (approximately)
  7. Rounding (optional): The problem specifies rounding to the nearest tenth. Since 0.192 is closer to 0.2 than 0.1, the rounded volume is:
  8. volume (mL) = 0.2 mL (rounded to one decimal place)

Therefore, the nurse should administer 0.2 mL of teriparatide.

Correct Answer is ["100"]

Explanation

  1. Total volume of the infusion: 50 mL (saline bag)
  2. Infusion time: 30 minutes = 0.5 hours (convert minutes to hours)
  3. We don't need the concentration of gentamicin for this calculation because we're only interested in the total volume delivered per hour.
  4. Flow rate: Since all the medication is delivered within the infusion time, the flow rate is equal to the total volume divided by the infusion time.

Flow rate (mL/hour) = Total volume (mL) / Infusion time (hours)

Flow rate = 50 mL / 0.5 hours Flow rate = 100.0 mL/hour

Therefore, the nurse should set the pump to deliver 100.0 mL/hour to infuse the 60 mg of gentamicin over 30 minutes.

Correct Answer is A

Explanation

A. Do not take any over-the-counter medications. This is crucial because many over-the-counter medications, including those containing acetaminophen, can further damage the liver. Avoiding these medications is essential to prevent further hepatic injury.
B. Eat a high carbohydrate, low fat, low protein diet. While diet can influence liver health, this specific dietary advice is less critical than preventing further liver damage from medications.
C. Call the crisis hot line if feeling lonely. This is important for mental health support, but the immediate physical health concern related to liver damage takes precedence.
D. Avoid exposure to large crowds. This may be relevant if the client is immunocompromised due to liver damage, but it is not as directly related to preventing further liver injury as avoiding certain medications.
