A nurse is assisting with the care of a client who is placed on supplemental oxygen for hypoxia. The nurse should identify that which of the following findings indicate the intervention was effective?

Choice A reason: Obtaining a prescription to administer insulin is an important action for the nurse to take, as insulin helps to lower the blood glucose level and reverse the metabolic acidosis caused by diabetic ketoacidosis. However, it is not the first action the nurse should take, as the client's hypoxia is a more urgent problem that requires immediate intervention.

Choice B reason: Obtaining a prescription for supplemental oxygen is the first action the nurse should take, as hypoxia is a life-threatening condition that can lead to tissue damage, organ failure, and death. The nurse should provide oxygen therapy to improve the client's oxygen saturation and prevent further complications.

Choice C reason: Obtaining a prescription to check the client's glucose level is a necessary action for the nurse to take, as glucose monitoring helps to evaluate the client's response to insulin therapy and guide further interventions. However, it is not the first action the nurse should take, as the client's hypoxia is a more urgent problem that requires immediate intervention.

Choice D reason: Obtaining a prescription to administer intravenous fluids is a beneficial action for the nurse to take, as fluid replacement helps to correct the dehydration, electrolyte imbalance, and hypotension caused by diabetic ketoacidosis. However, it is not the first action the nurse should take, as the client's hypoxia is a more urgent problem that requires immediate intervention.

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.
