Trimethoprim and sulfamethoxazole (Bactrim) BID for 7 days is ordered for a patient who has a recurrent relapse of an Escherichia coli UTI. The nurse instructs the patient to
increase the effectiveness of the drug by taking it with cranberry juice to acidify the urine.
take two of the pills a day for 5 days and reserve the rest of the pills to take it the symptoms reappear.
take the antibiotic for the full 7 days, even if symptoms improve in a few days.
return to the clinic in 3 days so that a urine culture can be done to evaluate the effectiveness of the drug.
The Correct Answer is C
The nurse's instruction to the patient is to take the antibiotic for the full 7 days, even if symptoms improve in a few days. This is because the full course of antibiotics is needed to eliminate the bacteria causing the UTI, even if the patient starts to feel better before the end of the treatment course. Failure to complete the full course of antibiotics can lead to the development of antibiotic resistance and the recurrence of the infection. The other options are not appropriate or effective measures for managing a UTI with antibiotics.

Correct Answer is B
Explanation
Diabetes insipidus is a condition where the body is not able to regulate water balance properly, leading to excessive urine output and dehydration. The patient's urine output of 800 ml/hr (option A) and low urine specific gravity of 1.003 (option C) is consistent with diabetes insipidus and requires monitoring, but they are not as immediately concerning as the patient's confusion and lethargy.
Confusion and lethargy may indicate severe dehydration, electrolyte imbalances, or even brain swelling (if the patient had a recent head injury, as mentioned in option D). These symptoms require immediate attention to prevent further complications and ensure the patient's safety.
Correct Answer is C
Explanation
Clostridium difficile is a highly contagious bacteria that can spread easily from person to person. The patient should be placed in a private room to prevent the spread of the infection to other patients. Contact isolation precautions should also be implemented, which involves wearing gloves and a gown when entering the patient's room, as well as washing hands thoroughly after leaving the room.
Options a and b are not directly related to the care of a patient with Clostridium difficile. Option d is also not directly related, although proper food handling and storage can help prevent the spread of other types of infections.
