A client is receiving miotics for the treatment of open-angle glaucoma. The nurse determines that a priority nursing problem is the risk for injury. This nursing problem is based on which etiology?

Choice A reason: Hypercholesterolemia, or high cholesterol, is not a primary concern when prescribing methylphenidate. While managing cholesterol levels is important for overall cardiovascular health, it does not directly interact with the administration of methylphenidate.

Choice B reason: Hypertension, or high blood pressure, is a critical condition to review before administering methylphenidate. Methylphenidate can increase blood pressure and heart rate, potentially exacerbating pre-existing hypertension. Monitoring and managing blood pressure is essential to prevent complications such as stroke or heart attack.

Choice C reason: Diabetes mellitus is important to manage, but it is not directly affected by methylphenidate. While some medications can influence blood sugar levels, methylphenidate primarily affects the central nervous system and cardiovascular system.

Choice D reason: Bronchitis, an inflammation of the bronchial tubes, is not a primary concern with methylphenidate use. Although respiratory conditions should be managed appropriately, they do not typically interact with the effects of methylphenidate.

Choice A Reason:

Spironolactone is a potassium-sparing diuretic often prescribed for heart failure. While monitoring for side effects is important, excessive bruising is not a common side effect of spironolactone. Bruising might be more relevant for patients on anticoagulants or those with clotting disorders.

Choice B Reason:

Replacing salt with a salt substitute is not advisable for patients on spironolactone. Many salt substitutes contain potassium chloride, which can lead to hyperkalemia (high potassium levels) when combined with spironolactone. Hyperkalemia can cause serious cardiac issues, including arrhythmias.

Choice C Reason:

Covering the skin before going outside is not specifically related to the use of spironolactone. This advice might be more relevant for medications that cause photosensitivity, such as certain antibiotics or diuretics like hydrochlorothiazide, but not spironolactone.

Choice D Reason:

Limiting the intake of foods high in potassium is crucial for patients taking spironolactone. Spironolactone can increase potassium levels in the blood, and consuming high-potassium foods (like bananas, oranges, and potatoes) can exacerbate this effect, leading to hyperkalemia. Hyperkalemia can be dangerous and cause symptoms such as muscle weakness, fatigue, and cardiac arrhythmias.
