A nurse is caring for a patient with a nasogastric (NG) tube and tests the pH of the secretions to verify correct placement of the tube.
What pH reading should the nurse expect?

Step 1 is to understand the question. The patient has been prescribed vancomycin 1 g in 250 mL dextrose 5% (D5W) to be administered over 2 hours via IV intermittent bolus. We need to calculate how many mL/hr the nurse should set the IV pump to deliver.

Step 2 is to calculate the rate. The total volume to be administered is 250 mL and the time for administration is 2 hours. So, the rate is 250 mL ÷ 2 hours = 125 mL/hr.

Choice A rationale

Fresh vegetables are generally not considered bladder irritants. They are part of a healthy diet and do not typically cause bladder irritation.

Choice B rationale

Red meat is not typically associated with bladder irritation. While some individuals may have specific dietary sensitivities, red meat is not commonly known to irritate the bladder.

Choice C rationale

Dairy products are not typically associated with bladder irritation. However, some individuals may have lactose intolerance or other specific sensitivities to dairy products.

Choice D rationale

Caffeinated beverages can irritate the bladder. Caffeine is a diuretic, which means it can increase urine production and potentially lead to bladder irritation.
