You are providing education to newly diagnosed asthma client on metered-dose inhaler use. Which statement by the client would indicate the need for additional education?

I will wash the inhaler once a week with running warm water."

I will administer the second puff 1 minute following the first puff."

I will rinse my mouth with water mouthwash after inhaler use

I will take slow deep breath while activating the inhaler."

Answer and Explanation

The Correct Answer is D

A) "I will wash the inhaler once a week with running warm water.": This statement is accurate. It is important to wash the inhaler, especially the mouthpiece, at least once a week to prevent the build-up of medication residue and ensure proper function. The recommendation of using warm water is appropriate, and washing weekly is commonly advised by healthcare providers.

B) "I will administer the second puff 1 minute following the first puff.": This is correct. When using a metered-dose inhaler, it is recommended to wait about 1 minute between puffs to allow the medication to be inhaled properly and for the first dose to be fully delivered before administering the second dose. This ensures that each dose is effective.

C) "I will rinse my mouth with water or mouthwash after inhaler use.": This is a correct statement, particularly for inhaled corticosteroids. Rinsing the mouth after using an inhaler helps prevent the development of oral thrush and other side effects such as irritation or infection. It’s also a good habit to remove any leftover medication from the mouth.

D) "I will take slow deep breaths while activating the inhaler.": This statement indicates the need for additional education. The correct technique involves inhaling slowly and deeply after activating the inhaler, not while activating it. If the client exhales forcefully while pressing the inhaler, they may not be able to inhale the medication effectively. It is crucial that the client activates the inhaler and then takes a slow, deep breath to ensure the medication is delivered properly into the lungs.

Correct Answer is C

Explanation

A) Prepare and administer the prescribed antidote: Administering an antidote would only be appropriate if the medication error resulted in a harmful reaction that requires immediate reversal. Since the issue here is the timing of medication administration, it is more important to first assess the client for any immediate effects rather than administering an antidote, which might not be necessary at this stage.

B) Notify the charge nurse, the nurse manager, and the prescriber: While notifying the appropriate staff is crucial, the first action should be assessing the client for any safety concerns or complications resulting from the medication administration error. Immediate evaluation of the client's condition should take precedence over notification.

C) Assess and identify the presence of urgent safety issues: The first priority in this situation is to assess the client for any adverse effects or reactions due to the medication being administered too quickly. This could include monitoring for signs of toxicity, adverse reactions, or changes in vital signs that may indicate a potential risk to the client’s health. Once the client's status is assessed, further actions such as notifying other staff or completing an incident report can follow.

D) Complete an incident report detailing the error: While documenting the error in an incident report is necessary, this should not be the first step. The immediate priority is to ensure the client’s safety by assessing their condition, as an error in the timing of medication administration may result in unwanted side effects or complications that need to be addressed first.

Correct Answer is B

Explanation

Here's the process for calculating the drug concentration after multiple half-lives:

First half-life: After 1 half-life, 50% of the original dose remains in the body.

200 mg x 0.50 = 100 mg remains after 1 half-life.

Second half-life: After 2 half-lives, 50% of the remaining drug will be eliminated.

100 mg x 0.50 = 50 mg remains after 2 half-lives.

Third half-life: After 3 half-lives, 50% of the remaining drug will be eliminated again.

50 mg x 0.50 = 25 mg remains after 3 half-lives.

Fourth half-life: After 4 half-lives, 50% of the remaining drug will be eliminated once more.

25 mg x 0.50 = 12.5 mg remains after 4 half-lives.

Now, we need to sum up the amount of drug remaining in the body at each half-life:

After 4 half-lives, there are 12.5 mg left from the original dose.

Total drug in the body after 4 half-lives = 200 mg - 12.5 mg = 375 mg.
