Furosemide is a diuretic used to treat fluid retention and high blood pressure. It does not have a known interaction with St. John’s wort.

Correct Answer is D

Explanation

Choice A rationale
Hyperglycemia is not a common adverse effect of colesevelam. Colesevelam is primarily used to lower cholesterol levels and can also help control blood sugar levels in patients with type 2 diabetes.
Choice B rationale
Stomatitis, or inflammation of the mouth, is not typically associated with colesevelam. This medication works in the intestines and is not absorbed into the bloodstream, so it does not commonly cause systemic side effects.
Choice C rationale
Fever is not a known adverse effect of colesevelam. The medication’s side effects are generally limited to the gastrointestinal system.
Choice D rationale
Constipation is a common adverse effect of colesevelam. This medication binds to bile acids in the intestines, which can lead to gastrointestinal side effects such as constipation.

A. Repeat up to four doses until pain is relieved. B. Store unused tablets at room temperature. C. Take two tablets at the onset of pain. D. Take the medication two hours prior to exercise.

Correct Answer is B

Explanation

Choice A rationale
Repeating up to four doses until pain is relieved 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.
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.
Choice C rationale
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.
Choice D rationale
Taking the medication two hours prior to exercise is incorrect. Nitroglycerin should be taken 5 to 10 minutes before an activity that may cause chest pain.
