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 B

Explanation

A. An increase in breath sounds may suggest improved airflow, but it does not necessarily indicate effective mobilization of secretions.
B. Absence of fine crackles indicates that there are no longer small airway secretions or fluid in the lungs, suggesting that the chest physiotherapy was effective in mobilizing secretions.
C. While the absence of coarse crackles is also a positive finding, fine crackles specifically indicate fluid or secretions in the small airways, making their absence a more direct indicator of the effectiveness of chest physiotherapy.

D. An increase in respiratory rate may indicate respiratory distress or worsening of the condition, rather than effectiveness of the chest physiotherapy in mobilizing secretions.

Correct Answer is C

Explanation

A. Wearing an N95 respiratory mask is not typically required for routine care of a toddler with respiratory syncytial virus unless performing procedures that generate aerosols.
B. Negative pressure rooms are generally reserved for patients with airborne infections like tuberculosis; respiratory syncytial virus does not typically require isolation in a negative pressure room.
C. Using a designated stethoscope helps prevent the spread of infection to other patients by avoiding cross-contamination.
D. Removing the disposable gown after leaving the toddler's room is appropriate for maintaining infection control but is not specific to caring for a toddler with respiratory syncytial virus.
