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 D
Explanation
The patient has been diagnosed with type 2 diabetes and reports following a reduced-calorie diet but has not lost any weight. This suggests that the patient may not be following the diet as prescribed or may have other factors affecting their blood glucose levels. Additionally, the patient did not bring their glucose monitoring record, which is an important tool for assessing blood glucose control over time.
In this situation, obtaining a fasting blood glucose level or an oral glucose tolerance test may provide a snapshot of the patient's blood glucose level at the time of the test, but these tests do not provide information about blood glucose control over the past few months. A urine dipstick for glucose is a less reliable method for assessing blood glucose control and is not recommended for routine monitoring.
Therefore, obtaining a glycosylated hemoglobin (HbA1c) level is the most appropriate test in this situation. HbA1c reflects the average blood glucose level over the past 2-3 months and is recommended for routine monitoring of blood glucose control in patients with diabetes. This test can provide valuable information about the effectiveness of the patient's diet and any other interventions aimed at controlling their blood glucose levels.
Correct Answer is C
Explanation
The operating room is a sterile environment, and it is critical to maintain a clean and controlled environment to reduce the risk of infection to the patient. The measures taken include maintaining positive air pressure, controlling temperature and humidity, filtering the air, using sterile surgical instruments, and limiting traffic in and out of the operating room. These measures help to prevent the spread of infectious agents that may be present in the operating room. While the other options (a, b, and d) may also be important considerations in the design of the operating room, preventing transmission of infection is the primary goal.
