A nurse is caring for a client who has nausea and is vomiting. The nurse should identify that the client is at risk for which of the following acid-base imbalances?

Choice A reason: Positioning the client supine is not a necessary action for the nurse to take, as the client can be in any comfortable position for the catheter removal. The nurse should explain the procedure to the client and provide privacy.

Choice B reason: Cleansing the perineal area with an antiseptic is not a required action for the nurse to take, as the catheter is already sterile and the risk of infection is low. The nurse should wear gloves and use a clean syringe to deflate the balloon.

Choice C reason: Deflating the balloon halfway and then pulling out the catheter is the correct action for the nurse to take, as it ensures that the catheter is removed smoothly and without causing trauma to the urethra. The nurse should apply gentle traction and observe the urine color and amount in the drainage bag.

Choice D reason: Having the client bear down during removal is not a recommended action for the nurse to take, as it can cause discomfort and bleeding. The nurse should instruct the client to relax and breathe normally during the procedure.

Choice A reason: Shaking the inhaler well before using it is a correct action for the client to take, as it helps to mix the medication and the propellant. However, it is not the best answer, as it is a general instruction that applies to most inhalers, not a specific one that indicates an understanding of the teaching.

Choice B reason: Holding the breath for 10 seconds after inhaling the medication is a correct action for the client to take, as it helps to keep the medication in the lungs and improve its absorption. However, it is not the best answer, as it is a general instruction that applies to most inhalers, not a specific one that indicates an understanding of the teaching.

Choice C reason: Rinsing the mouth with water after using the inhaler is the best answer, as it indicates an understanding of the teaching. Rinsing the mouth with water helps to prevent oral thrush, a fungal infection that can occur as a side effect of some inhalers, especially those that contain steroids.

Choice D reason: Waiting 30 seconds between each puff of the inhaler is not a correct action for the client to take, as it can reduce the effectiveness of the medication. The client should wait at least one minute between each puff of the inhaler, unless instructed otherwise by the provider.
