When monitoring patients on antitubercular drug therapy, the nurse knows that which drug may cause a decrease in visual acuity?
Rifampin
Ethambutol
Streptomycin
Isoniazid
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
Explanation
Choice A rationale:
Macrolides Macrolides, such as erythromycin and azithromycin, are a class of antibiotics that are typically used to treat infections caused by gram-positive bacteria and some respiratory tract infections. They are not the first line of treatment for urinary tract infections.
Choice B rationale:
Sulfonamides Sulfonamides, such as sulfamethoxazole, are often used to treat urinary tract infections. They work by stopping the growth of bacteria. Sulfonamides are often combined with other antibiotics like trimethoprim to increase their effectiveness. This combination is commonly known as co-trimoxazole.
Choice C rationale:
Carbapenems Carbapenems are a class of antibiotics that are usually reserved for serious infections caused by gram-negative bacteria. While they can be used to treat a variety of infections, they are not typically the first choice for urinary tract infections.
Choice D rationale:
Tetracyclines Tetracyclines are a group of broad-spectrum antibiotics that are effective against a wide range of bacteria. However, they are not typically used for urinary tract infections. They are more commonly used for infections such as acne, chlamydia, and Lyme disease.

Correct Answer is A
Explanation
Choice A rationale:
Reporting a near-miss using the facility’s recommended protocol and correcting the error on the MAR is the appropriate action. A “near-miss” in healthcare is a situation where an error could have happened, but didn’t, either by chance or timely intervention. It’s crucial to report these incidents as they provide valuable information for risk management and quality improvement. By analyzing near-misses, healthcare facilities can identify potential hazards and take preventive measures to ensure patient safety. Correcting the error on the MAR is also important to prevent the same mistake from happening in the future.
Choice B rationale:
Reporting the near-miss to the next shift before the next dose is due is not the best course of action. While it’s important to communicate any potential issues to the next shift, it’s more crucial to report the incident immediately using the facility’s recommended protocol. This allows for a timely investigation and corrective action. Waiting until the next shift could delay these processes and potentially put patient safety at risk.
Choice C rationale:
Correcting the MAR error but saying nothing because nothing happened is not an appropriate response. Even though the error did not result in any harm, it’s still important to report it. Near-misses are often indicators of underlying system issues that need to be addressed. By not reporting the incident, the opportunity to improve patient safety and prevent future errors is lost.
Choice D rationale:
Notifying the pharmacy about the error they almost caused is not the most appropriate action. While it’s important to communicate with the pharmacy if they were involved in the error, the first step should always be to report the near-miss using the facility’s recommended protocol. This ensures that the incident is properly documented and investigated, and that appropriate corrective actions are taken.
