The nurse is preparing client teaching materials on commonly used medications. Which client is most likely to benefit from a client education packet about simvastatin?

A) Chronotropic effect: This term refers to changes in heart rate. Angiotensin II receptor antagonists like valsartan primarily affect blood pressure and vascular tone, rather than directly altering heart rate.
B) Diuresis: Diuresis involves increased urine production. Although some antihypertensives can have a diuretic effect, valsartan primarily works through mechanisms other than increasing urine output.
C) Vasodilation: Angiotensin II receptor antagonists such as valsartan work by blocking the action of angiotensin II, which leads to vasodilation. This reduction in vascular resistance helps to lower blood pressure and is the primary therapeutic effect of valsartan.
D) Sympatholytic action: This refers to the suppression of sympathetic nervous system activity. Valsartan does not primarily act through sympathetic nervous system modulation but rather through direct vasodilation by blocking angiotensin II receptors.

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.
