A patient has been diagnosed with a urinary tract infection. From the antibiotics below which is the most appropriate?
Vancomycin
Erythromycin
Nitrofurantoin
Tetracycline
The Correct Answer is C
A. Vancomycin: Vancomycin is primarily used to treat serious gram-positive infections, such as MRSA or Clostridioides difficile. It is not a first-line treatment for uncomplicated urinary tract infections and is reserved for severe, resistant infections.
B. Erythromycin: Erythromycin has limited activity against common urinary pathogens such as Escherichia coli. It does not achieve adequate concentrations in the urinary tract, making it an inappropriate choice for treating UTIs.
C. Nitrofurantoin: Nitrofurantoin is commonly prescribed for uncomplicated urinary tract infections because it concentrates in the urine and is highly effective against typical UTI causing organisms. It is considered a first-line therapy for acute uncomplicated cystitis.
D. Tetracycline: Tetracycline is not commonly used for UTIs due to widespread bacterial resistance and less reliable urinary concentrations. Safer and more effective alternatives, such as nitrofurantoin, are preferred.

Correct Answer is C
Explanation
A. Encouraging the client to eat only high-fat foods:High-fat foods alone may increase calories but lack balanced nutrition. Overemphasis on fats can lead to digestive issues and does not address the need for vitamins, protein, and other essential nutrients.
B. Limiting the client's fluid intake to reduce hydration:Reducing fluids is unsafe and can lead to dehydration, constipation, and impaired metabolic function. Adequate hydration is essential for overall health and appetite.
C. Providing the patient with smaller, more frequent meals that are nutrient dense:Smaller, nutrient-rich meals are easier to consume for patients with decreased appetite, helping increase caloric intake while providing essential nutrients to improve overall nutritional status.
D. Encouraging the client to skip meals to increase calorie intake:Skipping meals reduces total caloric intake and worsens malnutrition. This approach is unsafe and counterproductive for a patient who is already undernourished.
Correct Answer is A
Explanation
A. Verify the medication and dose with another nurse before administration: High-alert medications carry a higher risk of causing significant harm if used incorrectly. Independent double-checking by another nurse ensures correct drug, dose, route, and patient, reducing the risk of serious medication errors.
B. Administer the medication without a second nurse check: Skipping a double-check increases the risk of administering an incorrect dose or medication. High-alert drugs require verification procedures because errors can have severe or fatal consequences.
C. Rely on the automated dispensing system to prevent errors: Automated systems reduce errors but are not foolproof. Human verification is still necessary, especially for high-alert medications, to catch potential mistakes that machines may miss.
D. Ask the client if they have taken this medication before: While patient history can provide context, clients may not accurately recall medications or doses. Verification through medical records and independent nurse checks is essential for safe administration.
