A preschool-aged child who is being tested for Streptococcal pharyngitis returns to the clinic for signs of scarlet fever. Which assessment finding
provides the clearest indication to the nurse that the child is experiencing a reaction to toxins that are created by Streptococcal bacteria.

Choice A reason: Blood pressure, heart rate, and temperature are vital signs that should be monitored in any client, but they are not laboratory results. ESRD can cause hypertension and cardiovascular complications, so blood pressure and heart rate should be controlled with medications and lifestyle modifications. Temperature should be monitored for signs of infection or inflammation.

Choice B reason: Leukocytes, neutrophils, and thyroxine are not specific laboratory results for ESRD. Leukocytes and neutrophils are types of white blood cells that indicate immune system activity and infection. Thyroxine is a thyroid hormone that regulates metabolism and growth. ESRD can affect the immune system and the thyroid function, but these are not the primary indicators of renal function.

Choice D reason: Erythrocytes, hemoglobin, and hematocrit are laboratory results that measure red blood cell count, oxygen-carrying capacity, and blood volume. ESRD can cause anemia due to reduced production of erythropoietin, a hormone that stimulates red blood cell formation in the bone marrow. Anemia can cause fatigue, pallor, shortness of breath, and chest pain. However, these are not the most significant laboratory results for ESRD.

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.
