A patient with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?

Until a smaller angle can be restored.

For long-term control of normal eye pressure.

For long-term control of pain and swelling.

Until the excess pressure is reduced.

Answer and Explanation

The Correct Answer is B

A. Until a smaller angle can be restored: Open-angle glaucoma is characterized by a gradual increase in intraocular pressure due to the obstruction of the outflow of aqueous humor, not by a narrow angle. The treatment aims to control eye pressure rather than restore the angle, which is more relevant to acute angle-closure glaucoma.
B. For long-term control of normal eye pressure: Open-angle glaucoma is a chronic condition that requires ongoing management to maintain normal intraocular pressure and prevent damage to the optic nerve. The prescribed eye drops help in managing intraocular pressure over the long term to prevent vision loss.
C. For long-term control of pain and swelling: Open-angle glaucoma typically does not present with pain and swelling. The goal of treatment is to control intraocular pressure rather than address pain or swelling, which are not primary symptoms of this condition.
D. Until the excess pressure is reduced: While initial treatment aims to reduce intraocular pressure, open-angle glaucoma requires ongoing use of medications to maintain normal pressure levels and prevent progression of the disease. Discontinuing the medication after initial pressure reduction can lead to a return of elevated intraocular pressure.

Correct Answer is B

Explanation

Simvastatin is a medication used to lower cholesterol and reduce the risk of cardiovascular events, such as heart attacks. It is most commonly prescribed to individuals with a history of heart disease, high cholesterol, or related conditions like angina. The other options are less likely to benefit from simvastatin based on the information provided.

A. Increases contractility. B. Increases preload. C. Decreases afterload. D. Decreases diastolic filing time.

Correct Answer is C

Explanation

A) Increases contractility: Metoprolol, a beta-blocker, actually decreases contractility. It reduces the force of contraction of the heart muscle, which can help reduce myocardial oxygen demand and improve outcomes after ACS. Increasing contractility would counteract the therapeutic goals of metoprolol in managing ACS.
B) Increases preload: Preload refers to the volume of blood in the ventricles at the end of diastole. Metoprolol does not increase preload; rather, it reduces myocardial workload and oxygen demand, which does not directly affect preload but rather the heart's performance overall.
C) Decreases afterload: Metoprolol reduces afterload indirectly by lowering blood pressure and decreasing heart rate, which helps reduce the workload on the heart. This reduction in afterload supports the therapeutic goals of metoprolol in managing ACS by decreasing the heart's work and improving cardiac efficiency.
D) Decreases diastolic filling time: Metoprolol slows the heart rate, which can lead to increased diastolic filling time, not a decrease. Increased filling time can be beneficial as it allows the heart more time to fill with blood between beats, thereby improving cardiac output.
