A patient presents to the emergency room with symptoms of severe eye pain, blurred vision, and nausea. The ophthalmologist diagnoses the patient with acute narrow-angle glaucoma. Which of the following interventions should be prioritized to alleviate the patient’s symptoms and prevent further complications?

Administer intravenous acetazolamide to reduce intraocular pressure.

Apply warm compresses to the affected eye to relieve pain.

Encourage the patient to drink plenty of fluids to stay hydrated.

Administer a mydriatic agent to dilate the pupil.

Advising the patient to limit fluid intake to prevent kidney damage is not appropriate. In fact, adequate hydration is crucial for patients with multiple myeloma to help flush out toxins and prevent kidney damage. Limiting fluid intake can lead to dehydration and worsen kidney function, which is already at risk due to the disease.

Answer and Explanation

The Correct Answer is A

Choice A Reason:

Administering intravenous acetazolamide is a critical intervention for acute narrow-angle glaucoma. Acetazolamide is a carbonic anhydrase inhibitor that reduces the production of aqueous humor, thereby lowering intraocular pressure (IOP) quickly. Reducing IOP is essential to prevent optic nerve damage and preserve vision. Normal IOP ranges from 10 to 21 mmHg, and in acute narrow-angle glaucoma, it can exceed 30 mmHg. Rapid reduction of IOP is crucial to alleviate symptoms and prevent further complications.

Choice B Reason:

Applying warm compresses to the affected eye is not an appropriate intervention for acute narrow-angle glaucoma. Warm compresses may provide temporary relief for some eye conditions, but they do not address the underlying issue of elevated intraocular pressure. In fact, warm compresses can potentially increase blood flow to the eye, which might exacerbate the condition.

Choice C Reason:

Encouraging the patient to drink plenty of fluids to stay hydrated is generally good advice for overall health, but it is not a prioritized intervention for acute narrow-angle glaucoma. Hydration does not directly impact intraocular pressure or alleviate the acute symptoms of glaucoma. The primary focus should be on reducing IOP to prevent optic nerve damage.

Choice D Reason:

Administering a mydriatic agent to dilate the pupil is contraindicated in acute narrow-angle glaucoma. Mydriatic agents can worsen the condition by further narrowing the anterior chamber angle, increasing intraocular pressure, and potentially causing more damage to the optic nerve. It is crucial to avoid pupil dilation in this scenario.

Correct Answer is C

Explanation

Choice A Reason:

The statement “If I forget to take my eye drops, I should wait until the next time they are due” is incorrect. For chronic open-angle glaucoma, it is important to take eye drops as prescribed to maintain consistent intraocular pressure control. If a dose is missed, the patient should take it as soon as they remember, unless it is almost time for the next dose. Skipping doses can lead to fluctuations in eye pressure, which can worsen the condition.

Choice B Reason:

The statement “Every two years I will need to have my vision checked by an eye doctor” is not accurate. Patients with chronic open-angle glaucoma typically need more frequent monitoring, often every 3 to 6 months, depending on the severity of the condition and the stability of their intraocular pressure. Regular check-ups are crucial for adjusting treatment and preventing vision loss.

Choice C Reason:

The statement “I should call the clinic before taking any over-the-counter medications” indicates an understanding of the teaching. Some over-the-counter medications can affect intraocular pressure or interact with glaucoma medications. Consulting with a healthcare provider before taking new medications helps ensure that they do not interfere with glaucoma management.

Choice D Reason:

The statement “When my vision improves, I will be able to stop taking the eye drops” is incorrect. Glaucoma is a chronic condition that requires ongoing treatment to manage intraocular pressure and prevent further damage to the optic nerve. Stopping medication can lead to a rapid increase in eye pressure and potential vision loss.

A. Administer propranolol intravenously. B. Administer dextrose 50% intravenously. C. Administer levothyroxine orally. D. Administer insulin to control hyperglycemia.

Correct Answer is A

Explanation

Choice A Reason:

Administering propranolol intravenously is the most appropriate initial intervention for managing a thyroid storm. Thyroid storm is a life-threatening condition characterized by severe hyperthyroidism, leading to symptoms such as tachycardia, hypertension, and hyperthermia. Propranolol, a non-selective beta-blocker, helps control these symptoms by reducing heart rate and blood pressure. Additionally, propranolol inhibits the peripheral conversion of T4 to T3, the more active form of thyroid hormone, thereby reducing the overall thyroid hormone activity. This makes it a critical first step in stabilizing the patient.

Choice B Reason:

Administering dextrose 50% intravenously is not the most appropriate initial intervention for thyroid storm. Dextrose 50% is typically used to treat severe hypoglycemia by rapidly increasing blood glucose levels. While maintaining adequate glucose levels is important, it does not address the primary issue of excessive thyroid hormone activity in thyroid storm.

Choice C Reason:

Administering levothyroxine orally is inappropriate in the context of thyroid storm. Levothyroxine is a synthetic form of T4 used to treat hypothyroidism, not hyperthyroidism. Administering it in a thyroid storm would exacerbate the condition by increasing the levels of thyroid hormone in the body.

Choice D Reason:

Administering insulin to control hyperglycemia is not the primary intervention for thyroid storm. While hyperglycemia can occur in thyroid storm due to increased metabolic activity, the immediate priority is to control the excessive thyroid hormone activity. Insulin administration would be secondary to stabilizing the patient’s thyroid function.
