An adult client is admitted to the critical care unit with systemic inflammatory response syndrome (SIRS) as a result of a postburn infection. The client has a long line peripherally inserted IV catheter for fluid and medication administration and current vital signs include temperature 102.8°F (39.3°C., heart rate 108 beats/minute, respirations 32 breaths/minute. Which action should the nurse implement first?

Choice A: Assessing pupillary response to light hourly is not related to dopamine administration. Dopamine does not affect the pupils or the cranial nerves that control them.

Choice B: Initiating seizure precautions is not necessary for a client receiving dopamine. Dopamine does not lower the seizure threshold or cause convulsions.

Choice C: Measuring urinary output every hour is an important intervention for a client receiving dopamine. Dopamine increases blood pressure and cardiac output, which improves renal perfusion and urine production. Urinary output is an indicator of the effectiveness of dopamine therapy and renal function.

Choice D: Monitoring serum potassium frequently is not directly related to dopamine administration. Dopamine does not affect potassium levels or cause hyperkalemia or hypokalemia. However, potassium levels may be affected by other factors such as fluid balance, renal function, and medications.

Choice D is correct because allowing time for the behavior and then redirecting the client to other activities is an effective intervention for a client with OCD who is repeatedly washing the top of the same table. OCD is a disorder characterized by recurrent and intrusive thoughts (obsessions) and repetitive and ritualistic behaviors (compulsions) that cause distress and impairment. The nurse should not interfere with or criticize the client's compulsions, as this can increase anxiety and resistance. The nurse should instead set limits on the time and place for the compulsions and gradually reduce them by offering alternative coping strategies or distractions.

Choice A is incorrect because encouraging the client to be calm and relax for a while is not an effective intervention for a client with OCD who is repeatedly washing the top of the same table. The client may not be able to relax or stop their compulsions, as they are driven by irrational fears or beliefs that are difficult to control. The nurse should not minimize or dismiss the client's feelings, as this can make them feel misunderstood or invalidated.

Choice B is incorrect because teaching the client thought-stopping techniques and how to refocus behaviors is not an effective intervention for a client with OCD who is repeatedly washing the top of the same table. Thought-stopping techniques are cognitive strategies that aim to interrupt or replace negative or unwanted thoughts with positive or neutral ones. However, these techniques may not work for clients with OCD, as their obsessions are often persistent and resistant to change. The nurse should not attempt to teach new skills or challenge the client's thoughts during an acute episode of compulsion, as this can increase anxiety and frustration.

Choice C is incorrect because assisting the client to identify stimuli that precipitate the activity is not an effective intervention for a client with OCD who is repeatedly washing the top of the same table. The client may not be able to identify or avoid the triggers that cause their compulsions, as they are often internal or irrational. The nurse should not focus on finding the cause or meaning of the compulsions, as this can reinforce their significance or validity.
