A nurse is preparing to administer 40 mg of furosemide intravenously.

The available furosemide is 10 mg/1 mL. How many mL should the nurse administer per dose? Round the answer to the nearest whole number.

Use a leading zero if it applies. Do not use a trailing zero.

Choice A rationale
Triptans, a class of medications commonly used to treat migraines, can cause vasoconstriction, or narrowing of the blood vessels. This can be problematic for patients with angina, a condition characterized by reduced blood flow to the heart. Vasoconstriction could potentially exacerbate this condition, leading to an increased risk of a heart attack. Therefore, the use of triptans may be contraindicated in patients with angina.

Choice B rationale
While asthma is a serious condition that requires careful management, it is not typically considered a contraindication for the use of triptans. Triptans work primarily on the blood vessels in the brain and do not typically interact with the bronchial tubes affected by asthma.
Choice C rationale
Age alone is not typically a contraindication for the use of triptans. However, older adults may have a higher risk of certain health conditions, such as heart disease, which could make the use of triptans more risky. It’s important for healthcare providers to consider the overall health status of the patient, not just their age, when deciding whether to prescribe triptans.
Choice D rationale
While stress can certainly exacerbate migraines, it is not typically a contraindication for the use of triptans. Triptans are designed to relieve the pain and other symptoms of migraines, regardless of their cause. If a patient’s migraines are triggered by stress, it may be beneficial to explore stress management techniques in addition to medication.

The correct answer is: = b. Prostaglandins

Choice A: Carbonic anhydrase inhibitors: These medications can be used for glaucoma, but they are not typically the first-line treatment due to potential side effects.

Choice B: Prostaglandins (Correct Answer) These are often the preferred initial medication for glaucoma because they are effective at lowering eye pressure, have minimal systemic side effects, and are typically used once daily.

Choice C: Alpha-agonists: These medications can be used as an adjunct to other glaucoma medications but are not usually the first choice due to potential side effects like dry mouth and fatigue.

Choice D: Beta-blockers: While once a common first-line treatment, beta-blockers have been largely replaced by prostaglandins due to potential side effects like slowed heart rate and worsened breathing problems.
