A client in the recovery room following a procedure is unable to void, so the nurse obtains a prescription to perform a straight catheterization. After inserting the catheter, the nurse observes that the client has an immediate output of 500 mL of clear yellow urine. Which action should the nurse implement next?

Choice A: Remove the catheter and palpate the client's bladder for residual distention. This is not the best action, as it may cause discomfort and trauma to the client. The catheter should not be removed until the bladder is fully emptied or up to 1,000 mL of urine is drained, as removing it too soon may cause urinary retention or infection.

Choice B: Remove the catheter and replace with an indwelling catheter. This is not the best action, as it may cause unnecessary exposure and trauma to the client. The catheter should not be replaced unless ordered by the healthcare provider, as replacing it may increase the risk of infection or urethral injury.

Choice C: Allow the bladder to empty completely or up to 1,000 mL of urine. This is the best action, as it can prevent bladder spasms, overdistention, or rupture. The nurse should monitor the urine output and color, and document the amount and characteristics of urine drained.

Choice D: Clamp the catheter for thirty minutes and then resume draining. This is not the best action, as it may cause pain and discomfort to the client. The catheter should not be clamped unless ordered by the healthcare provider, as clamping it may increase the risk of infection or bladder damage.

Choice B is correct because anxiety is the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Anxiety is a feeling of fear, nervousness, or apprehension that can interfere with coping and decision making. The nurse should assess the level and source of anxiety and provide emotional support and reassurance to the client. The nurse should also review the pain management techniques and explain the benefits and risks of different analgesic options.

Choice A is incorrect because knowledge deficit is not the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Knowledge deficit is a lack of information or understanding about a topic or situation that can affect learning and behavior. The nurse should evaluate the client's learning needs and provide appropriate education and resources, but this is not as urgent as addressing the client's anxiety.

Choice C is incorrect because pain intolerance is not the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Pain intolerance is an inability or unwillingness to endure pain that can affect quality of life and recovery. The nurse should assess the client's pain level and response to analgesics and adjust the pain management plan accordingly, but this is not as urgent as addressing the client's anxiety.

Choice D is incorrect because anticipatory grieving is not the priority nursing problem for this client who starts to cry and states, "I just know I can't handle all the pain." Anticipatory grieving is a process of mourning that occurs before an expected loss or death that can affect emotional and physical well-being. The nurse should acknowledge the client's feelings and provide empathy and support, but this is not as urgent as addressing the client's anxiety.
