Question 1 of 5
A client with a history of asthma is prescribed albuterol (Proventil). The nurse should instruct the client to:
Correct Answer: C
Rationale: Albuterol is a rescue inhaler used during acute asthma attacks to relieve bronchospasm.
Question 2 of 5
The primary health care provider prescribes 650 mg of an antibiotic to be administered intravenously every 6 hours. The medication label reads as follows: reconstitute with 4.8 mL of bacteriostatic water to yield 2 g in 5 mL. How many mL should the nurse withdraw from the vial for 1 dose? Fill in the blank. Record the answer using 1 decimal place.
Correct Answer: 1.6 mL
Rationale: Convert 2 g to mg and then use the formula for calculating medication doses. In the metric system, to convert larger to smaller, multiply by 1000 or move the decimal 3 places to the right.
Therefore, 2 g = 2000 mg. Formula: Desired / Available x Available Volume = 650 mg / 2000 mg x 5 mL = 1.625 mL = 1.6 mL.

The nurse-manager on the medical unit is teaching the staff about the medication reconciliation policy. The nurse teaches the staff that reconciliation is needed to ensure that clients are on the correct medications in which situations? Select all that apply.
