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 hold their breath for 2 seconds after inhalation.
Wash the MDI canister in warm water after each use.
Ask the client to inhale the medication quickly for 1 second.
Shake the MDI prior to administration.
The Correct Answer is D
Choice A rationale
Clients should be instructed to hold their breath for about 10 seconds after inhalation, not 2 seconds. This allows the medication to reach deeper into the lungs.
Choice B rationale
The MDI canister should not be washed after each use. Instead, it should be cleaned regularly to ensure proper functioning and avoid medication buildup.
Choice C rationale
Clients should be instructed to inhale the medication slowly and deeply over a few seconds, rather than quickly for 1 second. This ensures proper delivery of the medication to the lungs.
Choice D rationale
Shaking the MDI prior to administration is essential. This action mixes the medication evenly, ensuring that the correct dose is delivered with each puff.

Choice B rationale

Correct Answer is C
Explanation
Choice A rationale
Cheese is high in calcium, which can interfere with the absorption of iron by binding to it in the digestive tract, making it less available for absorption.
Choice B rationale
Antacids containing magnesium can interfere with the absorption of iron by increasing the pH of the stomach, reducing the solubility and absorption of iron.
Choice C rationale
Orange juice is high in vitamin C, which can enhance the absorption of iron by reducing it to a form that is more easily absorbed by the body.
Choice D rationale
Milk contains calcium, which can inhibit the absorption of iron. Calcium competes with iron for absorption in the intestines, leading to reduced iron absorption.
