A patient has a urinary tract infection.
The nurse knows that which class of drugs is especially useful for such infections?

Choice A rationale:

Providing written pamphlets for instruction can be a useful supplement, but it may not be the most effective method for teaching a skill like self-injection of insulin. This is because it lacks the hands-on practice and immediate feedback that can be crucial for learning a new physical skill.

Choice B rationale:

After demonstrating the procedure, allowing the patient to do several return demonstrations is considered one of the best methods for teaching a skill like self-injection of insulin. This approach, often referred to as “see one, do one, teach one,” allows the patient to observe the correct technique, practice it themselves, and then demonstrate their understanding by teaching it back. This method is particularly effective because it engages the patient in active learning and provides opportunities for immediate feedback and correction.

Choice C rationale:

Showing a video and allowing the patient to practice as needed on his own can be helpful, but it may not be as effective as other methods. This is because it lacks the immediate feedback and personalized instruction that can be provided in a one-onone teaching session. Additionally, practicing “as needed” may not provide the consistent repetition needed to master a new skill.

Choice D rationale:

Verbally explaining the procedure and providing written handouts for reinforcement can be effective, but it may not be sufficient for teaching a skill like self-injection of insulin. This is because it lacks the hands-on practice that is crucial for learning a new physical skill. Additionally, relying solely on verbal explanation and written handouts may not address all learning styles.

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.
