A nurse is reviewing the ABG values of a client who has pneumonia. Which of the following findings indicates the client is developing respiratory acidosis?

Choice A reason: Passing of flatus is not a reliable indicator of colostomy function, as it can occur even when there is an obstruction or ischemia in the bowel.

Choice B reason: Stoma is pinkish-red is a sign of a healthy and well-perfused colostomy, as it indicates that the blood supply to the bowel segment is adequate and there is no necrosis or infection.

Choice C reason: Tolerating a clear liquid diet is not a specific indicator of colostomy function, as it does not reflect the amount or consistency of the stool output.

Choice D reason: Absent bowel sounds are not a normal finding for a colostomy, as they can indicate a paralytic ileus or a bowel obstruction, which can cause complications such as distension, pain, or perforation.

Choice A reason: Urinating before and after sexual intercourse can help flush out any bacteria that may have entered the urinary tract during sexual activity, and prevent them from causing an infection.

Choice B reason: Increasing milk consumption to make the urine more alkaline is not a recommended instruction, as it may increase the risk of developing kidney stones or calcium deposits in the urinary tract.

Choice C reason: Emptying the bladder at least every 4 hours is a good practice, but not sufficient to prevent urinary tract infections. The nurse should also advise the client to drink plenty of fluids, especially water, to dilute the urine and flush out bacteria.

Choice D reason: Using vaginal douche once a week is not a recommended instruction, as it may alter the normal flora of the vagina and increase the risk of infection. The nurse should advise the client to avoid using any products that may irritate the genital area, such as perfumed soaps, sprays, or powders.

Choice E reason: Drinking cranberry juice daily is not a proven method to prevent urinary tract infections, although some studies suggest that it may have some benefits. The nurse should inform the client that cranberry juice may interact with some medications, such as warfarin, and that it may also increase the acidity of the urine, which can cause discomfort or burning sensation.
