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
Nifedipine is a calcium channel blocker that is effective in treating hypertension and angina. It works by relaxing the blood vessels, which lowers blood pressure and improves blood flow to the heart, reducing chest pain and hypertension.
Choice B rationale
Digoxin is not typically used to treat hypertension. It is primarily used for heart failure and atrial fibrillation to increase the strength of heart muscle contractions and regulate heart rhythm.
Choice C rationale
Heparin is an anticoagulant used to prevent and treat blood clots. It does not directly treat hypertension or angina and is used for conditions like deep vein thrombosis, pulmonary embolism, and during surgeries to prevent clot formation.
Choice D rationale
Captopril is an ACE inhibitor used to treat hypertension and heart failure. While it is effective for lowering blood pressure, it is not primarily used for treating angina compared to medications like nifedipine or other calcium channel blockers.
