A nurse is caring for a client that is diagnosed with allergic rhinitis.
Which of the following medication is a decongestant?
Albuterol.
Beclomethasone.
Diphenhydramine.
Phenylephrine.
The Correct Answer is D
Choice A rationale
Albuterol is a bronchodilator used to relax muscles in the airways and increase airflow to the lungs. It is primarily used in conditions such as asthma and chronic obstructive pulmonary disease (COPD), not as a decongestant.
Choice B rationale
Beclomethasone is a corticosteroid used to reduce inflammation in conditions such as asthma and allergic rhinitis. While it helps with symptoms, it is not classified as a decongestant.
Choice C rationale
Diphenhydramine is an antihistamine that alleviates allergy symptoms by blocking histamine action. It can relieve sneezing, itching, and runny nose but is not classified as a decongestant.
Choice D rationale
Phenylephrine is a decongestant that works by constricting blood vessels in the nasal passages. This reduces swelling and congestion, making it effective for managing symptoms of allergic rhinitis. .

Correct Answer is ["A","C"]
Explanation
Choice A rationale
Captopril is an Angiotensin Converting Enzyme (ACE) Inhibitor, which works by inhibiting the conversion of angiotensin I to angiotensin II. This leads to vasodilation and reduced blood pressure, making it effective in treating hypertension.
Choice C rationale
Lisinopril is also an Angiotensin Converting Enzyme (ACE) Inhibitor. It lowers blood pressure by blocking the formation of angiotensin II, a powerful vasoconstrictor, and thereby reducing systemic vascular resistance and blood pressure.
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.
