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.

Answer and Explanation

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.

Correct Answer is D

Explanation

D) Trough:
The trough level of a medication is the lowest concentration of the drug in the bloodstream before the next dose is administered. Monitoring the trough level helps ensure that the medication stays within a therapeutic range, minimizing the risk of toxicity and ensuring effectiveness.

A) Half-life:
Half-life refers to the time it takes for the concentration of a drug in the blood to decrease by half. It is related to how long the drug stays in the system but does not specifically indicate the lowest concentration.

B) Peak:
The peak level is the highest concentration of the drug in the bloodstream after administration. It is used to assess the maximum effect of the drug, not the lowest concentration.

C) Toxic:
Toxic level refers to the concentration of a drug at which it can cause adverse effects or toxicity. It is not related to the lowest concentration but rather to potentially harmful levels.

A. "Crushing the medication is a good idea, and I can mix it in some ice cream for you." B. "Crushing the medication might cause you to have a stomachache or indigestion." C. "Crushing the medication would release all the medication at once, rather than over time." D. "Crushing is unsafe, as it destroys the ingredients in the medication."

Correct Answer is C

Explanation

A) "Crushing the medication is a good idea, and I can mix it in some ice cream for you."
Crushing enteric-coated medications is not advisable as it can disrupt the medication’s intended release mechanism. Enteric coatings are designed to protect the stomach lining and ensure that the medication is released in the intestines. Crushing the medication would bypass these protective mechanisms.

B) "Crushing the medication might cause you to have a stomachache or indigestion."
While this statement is somewhat true, it does not fully address the primary concern. Enteric-coated medications are designed to protect the stomach lining and to ensure proper absorption. Crushing them could lead to other issues beyond just stomachache or indigestion.

C) "Crushing the medication would release all the medication at once, rather than over time."
This is the most accurate response. Enteric-coated aspirin is designed to dissolve in the intestines rather than the stomach, and crushing it would lead to the medication being released all at once, which could potentially cause irritation or harm to the stomach and reduce the medication's effectiveness.

D) "Crushing is unsafe, as it destroys the ingredients in the medication."
While crushing enteric-coated medications can be unsafe, the primary issue is not the destruction of the ingredients but the loss of the medication’s intended release mechanism. This can result in adverse effects or reduced efficacy.
