A nurse is collecting data on a client who has mitral valve stenosis. Which of the following findings should the nurse expect?

Choice A reason: The pulse oximeter might not be accurate during times of excessive movement is a correct statement, as movement can interfere with the detection of the pulse and the oxygen saturation. The parents should try to keep the infant still and calm while using the pulse oximeter.

Choice B reason: We will notify the doctor if the pulse oximeter consistently reads 100% is an incorrect statement, as it indicates a misunderstanding of the normal range of oxygen saturation. The parents should not be alarmed if the pulse oximeter reads 100%, as it means that the infant's blood is fully saturated with oxygen. The normal range of oxygen saturation for infants is 95% to 100%.

Choice C reason: The probe of the pulse oximeter can be applied to a finger or a toe is a correct statement, as these are suitable sites for measuring the oxygen saturation in infants. The parents should make sure that the probe fits snugly and securely on the infant's finger or toe.

Choice D reason: We will rotate the probe of the pulse oximeter every 24 hours is a correct statement, as it helps to prevent skin irritation, pressure ulcers, or infection from prolonged contact with the probe. The parents should also check the infant's skin regularly for any signs of redness, swelling, or pain.

Choice A reason: Donning sterile gloves is an essential step to prevent contamination and infection during the insertion of an indwelling urinary catheter. The nurse should also use aseptic technique and a sterile catheter kit.

Choice B reason: Applying an oil-based lubricant to the indwelling urinary catheter is not recommended, as it can damage the latex material and increase the risk of catheter-associated urinary tract infection (CAUTI). The nurse should use a water-soluble lubricant instead.

Choice C reason: Testing the balloon on the indwelling urinary catheter before insertion is a good practice, as it ensures that the balloon is functioning properly and does not leak or burst. The nurse should inflate and deflate the balloon with sterile water or saline using a syringe.

Choice D reason: Using one cotton swab to clean the client's urinary meatus is not sufficient, as it may not remove all the bacteria and debris. The nurse should use at least three cotton swabs and clean the meatus from front to back in a circular motion. The nurse should also use an antiseptic solution such as chlorhexidine or povidone-iodine.
