A nurse is reinforcing teaching about a tonometry examination with a client who has manifestations of glaucoma. Which of the following statements should the nurse include in the teaching?

Choice A Reason:

Macular degeneration primarily affects central vision and is characterized by a gradual loss of vision rather than sudden symptoms. It does not typically cause flashes of light, shadows over the visual field, or floaters. These symptoms are more indicative of a retinal issue.

Choice B Reason:

Cataracts cause clouding of the lens, leading to blurred vision and difficulty seeing at night. However, they do not cause sudden flashes of light, shadows over the visual field, or floaters. Cataracts develop gradually and do not present with acute symptoms.

Choice C Reason:

Glaucoma is associated with increased intraocular pressure, which can lead to gradual loss of peripheral vision. While acute angle-closure glaucoma can cause sudden symptoms, it typically presents with severe eye pain, headache, and nausea, rather than flashes of light and floaters.

Choice D Reason:

Retinal detachment is characterized by the sudden onset of flashes of light, floaters, and a shadow or curtain over the visual field. These symptoms occur because the retina is pulling away from its normal position, which can lead to vision loss if not treated promptly. Immediate medical attention is required to prevent permanent vision loss.

Choice A Reason:

Monitoring platelet counts and assessing for signs of bleeding is crucial for managing thrombocytopenia. Thrombocytopenia is characterized by a low platelet count, which increases the risk of bleeding. Regular monitoring helps in detecting any significant drops in platelet levels, allowing for timely interventions to prevent severe bleeding. Assessing for signs of bleeding, such as petechiae, bruising, or nosebleeds, is essential to manage the condition effectively and prevent complications.

Choice B Reason:

Administering aspirin to manage pain and prevent clot formation is not appropriate for patients with thrombocytopenia. Aspirin is an antiplatelet agent that inhibits platelet function, which can exacerbate bleeding tendencies in patients with low platelet counts. Using aspirin in this context could increase the risk of bleeding and is therefore contraindicated.

Choice C Reason:

Administering a diuretic to reduce fluid retention and swelling is not relevant for managing thrombocytopenia. Diuretics are used to manage conditions like hypertension and edema but do not address the underlying issue of low platelet counts. In fact, diuretics can lead to electrolyte imbalances, which may complicate the patient’s condition further.

Choice D Reason:

Encouraging the patient to increase physical activity to improve circulation is not a priority intervention for thrombocytopenia. While physical activity is generally beneficial for overall health, it can increase the risk of trauma and bleeding in patients with low platelet counts. It is important to avoid activities that could lead to injury and bleeding in these patients.
