The patient with glaucoma is usually started on the lowest dose of medication. Which of the following is the preferred initial ophthalmic medication?
Carbonic anhydrase inhibitors
Prostaglandins
Alpha-agonists
Beta-blockers
The Correct Answer is B
The correct answer is: = b. Prostaglandins
Choice A: Carbonic anhydrase inhibitors: These medications can be used for glaucoma, but they are not typically the first-line treatment due to potential side effects.
Choice B: Prostaglandins (Correct Answer) These are often the preferred initial medication for glaucoma because they are effective at lowering eye pressure, have minimal systemic side effects, and are typically used once daily.
Choice C: Alpha-agonists: These medications can be used as an adjunct to other glaucoma medications but are not usually the first choice due to potential side effects like dry mouth and fatigue.
Choice D: Beta-blockers: While once a common first-line treatment, beta-blockers have been largely replaced by prostaglandins due to potential side effects like slowed heart rate and worsened breathing problems.

Correct Answer is A
Explanation
Choice A rationale
The patient lying in bed with their head elevated to 35 degrees while eating could pose a risk for aspiration, especially for a patient with Huntington’s disease. Huntington’s disease is a neurodegenerative disorder that can cause difficulties with swallowing and motor control.
Therefore, it is recommended that the patient be as upright as possible, ideally in a seated position, during meals to reduce the risk of aspiration.
Choice B rationale
Providing thickened liquids is a common intervention for patients with Huntington’s disease who have difficulty swallowing. Thickened liquids are easier to control and swallow, reducing the risk of aspiration.
Choice C rationale
Not rushing the patient in eating each bite is a recommended practice. Patients with Huntington’s disease often have difficulty with motor control, including swallowing. Allowing the patient to take their time can help prevent choking and aspiration.
Choice D rationale
Ensuring that the patient’s food is minced is another recommended practice for patients with Huntington’s disease. Minced food is easier to chew and swallow, which can help prevent choking and aspiration.
Correct Answer is D
Explanation
Choice A rationale:
Respiratory acidosis is characterized by a low pH (less than 7.35), a high PaCO2 (greater than 45 mm Hg), and a normal or high HCO3 (22-26 mEq/L). It occurs when there is a buildup of carbon dioxide in the blood due to impaired ventilation.
The patient's ABGs do not align with respiratory acidosis because the pH is elevated (7.6), and the PaCO2 is within the normal range (40 mm Hg).
Choice B rationale:
Respiratory alkalosis is characterized by a high pH (greater than 7.45), a low PaCO2 (less than 35 mm Hg), and a normal or low HCO3 (22-26 mEq/L). It occurs when there is excessive loss of carbon dioxide through hyperventilation.
The patient's ABGs do not align with respiratory alkalosis because the HCO3 is elevated (32 mEq/L), which is not typical for this condition.
Choice C rationale:
Metabolic acidosis is characterized by a low pH (less than 7.35), a normal or low PaCO2 (less than 40 mm Hg), and a low HCO3 (less than 22 mEq/L). It occurs when there is an excess of acid in the body or a loss of bicarbonate.
The patient's ABGs do not align with metabolic acidosis because the pH is elevated (7.6), and the HCO3 is elevated (32 mEq/L).
Choice D rationale:
Metabolic alkalosis is characterized by a high pH (greater than 7.45), a normal or high PaCO2 (40-45 mm Hg), and an elevated HCO3 (greater than 26 mEq/L). It occurs when there is an excess of bicarbonate in the body or a loss of acid.
The patient's ABGs align with metabolic alkalosis because of the high pH (7.6), normal PaCO2 (40 mm Hg), and elevated HCO3 (32 mEq/L).
