A nurse in a provider’s office is collecting data from an older adult client who has type 2 diabetes mellitus. Which of the following findings is a manifestation of hyperglycemia?

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:

Administering IV levothyroxine is the priority intervention for a patient with myxedema coma. Myxedema coma is a severe form of hypothyroidism that requires immediate thyroid hormone replacement to correct the deficiency and stabilize the patient’s condition. Intravenous levothyroxine is preferred because it provides a rapid increase in thyroid hormone levels, which is crucial for reversing the life-threatening symptoms of myxedema coma, such as hypothermia, bradycardia, and altered mental status.

Choice B Reason:

Starting broad-spectrum antibiotics is not the primary intervention for myxedema coma. While infections can precipitate myxedema coma and should be treated if present, the immediate priority is to address the severe hypothyroidism with thyroid hormone replacement. Antibiotics may be administered if an infection is suspected or confirmed, but they do not directly address the underlying thyroid hormone deficiency.

Choice C Reason:

Administering corticosteroids immediately is important but not the highest priority. Corticosteroids are often given to patients with myxedema coma to treat potential adrenal insufficiency, which can coexist with severe hypothyroidism. However, the primary intervention remains the administration of thyroid hormone replacement to correct the hypothyroid state.

Choice D Reason:

Initiating fluid restriction is not appropriate for managing myxedema coma. Patients with myxedema coma often require careful fluid management to address potential hyponatremia and maintain hemodynamic stability. Fluid restriction is not a standard intervention for this condition and does not address the critical need for thyroid hormone replacement.
