A nurse is collecting data from a client who has open-angle glaucoma. Which of the following symptoms should the nurse expect the patient to report?

Choice A reason: Fall prevention is the most important safety measure for an elderly client with osteoporosis, as falls can result in fractures and other complications. The nurse should assess the client's risk factors for falls, such as impaired vision, balance, or mobility, and implement interventions to reduce them, such as providing adequate lighting, removing clutter, and using assistive devices.

Choice B reason: Pressure injury prevention is also important for an elderly client, but not as crucial as fall prevention for a client with osteoporosis. Pressure injuries are caused by prolonged pressure on the skin, especially over bony prominences. The nurse should reposition the client frequently, use pressure-relieving devices, and monitor the skin for signs of breakdown.

Choice C reason: Cognitive impairment prevention is not a specific safety measure for an elderly client with osteoporosis, although it may affect the client's ability to follow instructions and adhere to treatment. Cognitive impairment may be caused by various factors, such as dementia, delirium, or medication side effects. The nurse should assess the client's mental status, provide orientation and stimulation, and manage any underlying causes.

Choice D reason: Functional decline prevention is not a specific safety measure for an elderly client with osteoporosis, although it may affect the client's quality of life and independence. Functional decline may be caused by various factors, such as pain, weakness, or depression. The nurse should encourage the client to participate in physical and occupational therapy, promote self-care activities, and provide emotional support.

Choice A reason: This is the correct answer because stopping the KCl infusion is the first and most urgent action that the nurse should take. A high level of potassium in the blood, or hyperkalemia, can cause life-threatening cardiac arrhythmias and muscle weakness. The nurse should stop the source of excess potassium, which is the KCl infusion, and monitor the client's vital signs, electrocardiogram, and symptoms.

Choice B reason: This is not the correct answer because administering oral KCl is not the first or appropriate action that the nurse should take. Oral KCl would increase the potassium level in the blood, which is already too high. The nurse should avoid giving any potassium supplements or foods that are high in potassium, such as bananas, oranges, and potatoes.

Choice C reason: This is not the correct answer because encouraging fluids for dilution is not the first or effective action that the nurse should take. Fluids alone would not lower the potassium level in the blood, but rather dilute the concentration of other electrolytes, such as sodium and calcium. The nurse should administer fluids only as prescribed by the physician, and in conjunction with other treatments, such as diuretics, insulin, or sodium bicarbonate.

Choice D reason: This is not the correct answer because calling the pharmacy is not the first or priority action that the nurse should take. Calling the pharmacy may be necessary to obtain the medications that can lower the potassium level in the blood, such as diuretics, insulin, or sodium bicarbonate. However, the nurse should first stop the KCl infusion and notify the physician, who will order the appropriate medications and dosages.
