When monitoring patients on antitubercular drug therapy, the nurse knows that which drug may cause a decrease in visual acuity?

Rifampin

Ethambutol

Streptomycin

Isoniazid

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Rifampin Rifampin is an antitubercular drug that is effective against all strains of Mycobacterium tuberculosis. It works by inhibiting the synthesis of RNA in the bacteria, preventing them from reproducing. However, it does not typically cause a decrease in visual acuity.

Choice B rationale:

Ethambutol Ethambutol is an antitubercular drug that can cause ocular toxicity in the form of visual field changes. It is known to induce toxic optic neuropathy, which is quite common and can lead to a decrease in visual acuity. Patients on Ethambutol therapy are advised to report any changes in visual acuity or eye discomfort immediately to their healthcare provider.

Choice C rationale:

Streptomycin Streptomycin is an aminoglycoside antibiotic used in the treatment of tuberculosis. It works by inhibiting protein synthesis in bacteria. While it can cause side effects such as ototoxicity and nephrotoxicity, it is not typically associated with a decrease in visual acuity.

Choice D rationale:

Isoniazid Isoniazid is a first-line antitubercular drug that works by inhibiting the synthesis of mycolic acids in the cell wall of Mycobacterium tuberculosis. While it can cause peripheral neuropathy, it is not typically associated with a decrease in visual acuity.

Correct Answer is ["B","C","D"]

Explanation

Choice A rationale:

Polyuria, which is frequent or excessive urination, is not typically a symptom of hypoglycemia. It is more commonly associated with hyperglycemia, or high blood sugar levels.

Choice B rationale:

Sweating is indeed a common symptom of hypoglycemia. When blood sugar levels fall too low, the body may respond by sweating as it releases adrenaline in response to the hypoglycemic state.

Choice C rationale:

Tachycardia, or a fast heartbeat, is another common symptom of hypoglycemia. This is part of the body’s response to low blood sugar levels, as it releases adrenaline to try to raise these levels.

Choice D rationale:

Blurry vision can be a symptom of hypoglycemia. When blood sugar levels fall, it can affect the ability of the eyes to focus, leading to blurry vision.

Choice E rationale:

Polydipsia, or excessive thirst, is not typically a symptom of hypoglycemia. Like polyuria, it is more commonly associated with hyperglycemia.

A. Take it with cheese and crackers or yogurt. B. Take an antacid with each dose as needed. C. Drink a full glass of water with each dose. D. Take each dose with a glass of milk.
