Choice B rationale

 

Storing unused tablets at room temperature is correct. Nitroglycerin tablets should be stored in their original container at room temperature, away from moisture and heat.

Taking two tablets at the onset of pain is incorrect. The correct instruction is to take one tablet at the onset of pain and repeat every 5 minutes if needed, up to a maximum of three tablets in 15 minutes.

Correct Answer is D

Explanation

Choice A rationale

Asthma is not a contraindication for sumatriptan. Sumatriptan is a selective serotonin receptor agonist used to treat migraines by constricting blood vessels in the brain. It does not have a significant impact on respiratory conditions like asthma.

Choice B rationale

Kidney disease is not a contraindication for sumatriptan. However, caution is advised when using sumatriptan in patients with severe renal impairment due to potential accumulation of the drug and its metabolites.

Choice C rationale

Rheumatoid arthritis is not a contraindication for sumatriptan. Sumatriptan’s mechanism of action does not interfere with the inflammatory processes involved in rheumatoid arthritis.

Choice D rationale

Coronary artery disease (CAD) is a contraindication for sumatriptan. Sumatriptan can cause vasoconstriction of coronary arteries, which can exacerbate CAD and increase the risk of myocardial infarction or other cardiac events.

Sitagliptin is a DPP-4 inhibitor used to manage blood sugar levels in type 2 diabetes but does not specifically slow the progression of nephropathy.

Choice B rationale

Glipizide is a sulfonylurea that helps control blood sugar levels but does not have a direct effect on slowing nephropathy progression.

Choice C rationale

Metoprolol is a beta-blocker used to manage hypertension but does not specifically target nephropathy progression.

Choice D rationale

Losartan is an angiotensin II receptor blocker (ARB) that helps manage hypertension and has been shown to slow the progression of nephropathy in patients with type 2 diabetes.
