A client has a new prescription for a medication to be given via inhalation through a metered-dose inhaler (MDI). Which of the following education should the nurse include?
Wait at least 5 minutes between puffs if the client has different medications via inhalation.
Wait at least 10 minutes between puffs.
None of the above.
All of the above.
The Correct Answer is A
Choice A rationale
Waiting at least 5 minutes between puffs allows the first dose to take effect, optimizing absorption and reducing side effects when different inhaled medications are used.
Choice B rationale
Waiting 10 minutes between puffs is unnecessary and might reduce adherence to treatment due to the prolonged interval.
Choice C rationale
"None of the above" does not provide a valid education point for using metered-dose inhalers.
Choice D rationale
"All of the above" is incorrect as it includes a recommendation that is not necessary (waiting 10 minutes). .

Correct Answer is D
Explanation
Choice A rationale
Intravenous, intramuscular, and intradermal routes bypass the first-pass effect as they do not pass through the liver first.
Choice B rationale
Enteric-coated tablets and capsules are designed to bypass the stomach and dissolve in the intestines, reducing the first-pass effect.
Choice C rationale
The first-pass effect involves the liver metabolizing and inactivating a portion of the medication on its first pass through the liver.
Choice D rationale
Enteral medications, which pass through the digestive system, may require higher doses due to the first-pass effect where the liver metabolizes the medication before it reaches systemic circulation. .
Correct Answer is A
Explanation
Choice A rationale
Lactated Ringers (LR) is an isotonic solution, which means it has the same osmolarity as blood plasma. This property makes LR suitable for rehydrating patients without causing a significant shift of fluids between compartments, maintaining the balance of electrolytes.
Choice B rationale
0.45% Sodium Chloride is a hypotonic solution, meaning it has a lower osmolarity compared to blood plasma. This type of solution would cause fluid to move into cells, potentially leading to cellular swelling.
Choice C rationale
Dextrose in Lactated Ringers is a hypertonic solution because the added dextrose increases the osmolarity. This solution can cause fluid to shift out of cells, leading to cellular shrinkage, which is not ideal for rehydration.
Choice D rationale
None of the above is incorrect because Lactated Ringers (LR) is indeed an isotonic solution.
