A client with peptic ulcer disease receives a new prescription for cimetidine. Which statement provided by the client requires additional instruction by the nurse?

Choice A reason: Using the eye drops until the excess pressure is reduced is not an accurate response, as it implies that the eye drops are only a temporary treatment. Open-angle glaucoma is a chronic condition that causes increased pressure in the eye due to impaired drainage of the aqueous humor. The eye drops are used to lower the eye pressure and prevent further damage to the optic nerve. The client will need to use the eye drops for the rest of their life, unless the healthcare provider advises otherwise.

Choice B reason: Using the eye drops for long-term control of pain and swelling is not an accurate response, as it does not address the main goal of the treatment. Open-angle glaucoma does not usually cause pain or swelling, as the pressure builds up gradually and painlessly. The eye drops are used to lower the eye pressure and prevent vision loss, not to relieve inflammation or discomfort.

Choice C reason: Using the eye drops until a smaller angle can be restored is not an accurate response, as it confuses open-angle glaucoma with closed-angle glaucoma. Open-angle glaucoma is characterized by a wide and open angle between the iris and the cornea, which allows the aqueous humor to flow freely. Closed-angle glaucoma is characterized by a narrow or closed angle that blocks the drainage of the aqueous humor. The eye drops are used to lower the eye pressure and prevent further damage to the optic nerve, not to change the angle of the eye.

Choice D reason: Using the eye drops for long-term control of normal eye pressure is the most accurate response, as it reflects the purpose and duration of the treatment. Open-angle glaucoma is a chronic condition that requires lifelong management. The eye drops are used to lower the eye pressure and prevent vision loss, which can occur if the pressure is too high for too long. The client should use the eye drops as prescribed and follow up with the healthcare provider regularly.

Choice A reason: This is not a correct instruction for the nurse to provide to the client's caregivers. When using the discus, the client should breathe out slowly and gently away from the mouthpiece, not into it. Breathing out rapidly into the mouthpiece can cause the powder to disperse and reduce the amount of medication delivered to the lungs. The client should also rinse the mouthpiece with water after each use and dry it thoroughly.

Choice B reason: This is not a correct instruction for the nurse to provide to the client's caregivers. The discus is not intended for use during an acute asthma attack, as it does not provide immediate relief of bronchospasm. The discus is a combination of fluticasone, a corticosteroid that reduces inflammation, and salmeterol, a long-acting beta-agonist that relaxes the airway muscles. The discus is a maintenance therapy that should be used regularly to prevent asthma symptoms and exacerbations. The client should also have a rescue inhaler, such as albuterol, for quick relief of asthma attacks.

Choice C reason: This is not a correct instruction for the nurse to provide to the client's caregivers. Clients using the discus may experience increased blood pressure, not decreased, as a possible side effect of salmeterol. Salmeterol can stimulate the beta receptors in the heart and blood vessels, causing tachycardia, palpitations, and hypertension. The nurse should monitor the client's blood pressure and heart rate regularly and report any abnormal findings to the healthcare provider.

Choice D reason: This is the correct instruction for the nurse to provide to the client's caregivers. The discus should not be used more than twice daily, as it can increase the risk of adverse effects and reduce the effectiveness of the medication. The discus should be used once in the morning and once in the evening, about 12 hours apart, to provide optimal control of asthma symptoms. The nurse should teach the client and the caregivers how to use the discus correctly and safely, and to follow the prescribed dosage and schedule.
