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.

Answer and Explanation

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

Furosemide is a loop diuretic that works by blocking the reabsorption of sodium and chloride in the ascending loop of Henle in the kidney, leading to increased urine output. However, this medication can also cause potassium loss through increased urinary excretion, which can lead to hypokalemia (low potassium level). Hypokalemia can cause confusion, weakness, and other neurological symptoms.

The normal range for serum potassium is 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L is below the normal range and is considered hypokalemic. Therefore, the nurse should correlate the client's confusion with the low potassium level and notify the healthcare provider to adjust the medication or provide potassium supplements if indicated.

A. Breath sounds. B. abdominal girth. C. Bowel sounds. D. Apical pulse.

Correct Answer is A

Explanation

GERD can increase the risk of aspiration (inhalation of stomach contents into the lungs), which can cause respiratory issues, including abnormal breath sounds. In these cases, monitoring of breath sounds may be more appropriate than monitoring of bowel sounds.

Bowel sounds are not typically monitored for GERD patients as GERD is a condition that aﬀects the esophagus and the stomach, not the intestines. GERD is caused by the reﬂux of stomach contents into the esophagus, which can cause symptoms such as heartburn and regurgitation.

Abdominal girth is not routinely monitored for GERD patients as it is not typically related to the condition. GERD is a disorder that aﬀects the esophagus and stomach and does not typically cause significant changes in abdominal size or girth. In rare cases, GERD can be complicated by a condition known as a para oesophageal hernia, which can cause a visible bulge in the abdomen. In these cases, monitoring of abdominal size and shape may be necessary.

The apical pulse is not routinely monitored for GERD patients as it is not directly related to the condition. GERD is a disorder that aﬀects the digestive system, specifically the esophagus and stomach and does not typically have an impact on heart rate or rhythm.
