A nurse is preparing to administer a metered dose inhaler (MDI) medication to a client. Which of the following actions should the nurse take?
Ask the client to inhale the medication quickly for 1 second.
Ask the client to hold their breath for 2 seconds after inhalation.
Shake the MDI prior to administration.
Wash the MDI canister in warm water after each use.
The Correct Answer is C
A) Ask the client to inhale the medication quickly for 1 second:
The client should inhale the medication slowly and deeply, not quickly. A rapid inhalation can reduce the effectiveness of the medication as it may not reach the deeper parts of the lungs effectively.
B) Ask the client to hold their breath for 2 seconds after inhalation:
The client should hold their breath for about 10 seconds after inhalation to allow the medication to settle in the lungs and be absorbed. Holding the breath for just 2 seconds is typically insufficient for optimal medication delivery.
C) Shake the MDI prior to administration:
Shaking the MDI before use is important to ensure that the medication is properly mixed and delivered in the correct dose. Failure to shake the MDI can result in an uneven distribution of medication.
D) Wash the MDI canister in warm water after each use:
The MDI canister should not be washed frequently, as this can affect the device's function and lead to potential contamination. The canister should be cleaned as per the manufacturer’s instructions, typically every few days or as needed.

Explanation
Calculating the Lidocaine Dose
Problem: Administer 50 mg of lidocaine IV bolus. The available concentration is 200 mg/mL.
Steps:
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (50 mg) and the concentration of the medication (200 mg/mL).
Proportion:
x mL / 50 mg = 1 mL / 200 mg
Cross-multiply:
200x = 50
Solve for x:
x = 50 / 200
x = 0.25
Answer: The nurse should administer 0.3 mL of lidocaine per dose(rounded to the nearest tenth).
