- white blood cells, 4500 to 11,000 cells/mm3; thyroid-stimulating hormone, 0.2 to 5.4 microunits/mL; magnesium, 1.6 to 2.6 mg/dL; calcium, 8.6 to 10.0 mg/dL; blood urea nitrogen, 5 to 20 mg/dL; and serum creatinine, 0.6 to 1.3 mg/dL. A 1-year-old infant is admitted to the hospital for control of tonic-clonic seizures. The nurse helps minimize the infant's risk for injury by - Removing any toy with bright blinking lights Keeping the sides rails of the child's bed padded Turning the infant on the side during any seizure A 16-year-old child is brought to the emergency department by his mother with a complaint that the child just experienced a tonic-clonic seizure. On arrival in the emergency department no apparent seizures were occurring. The mother states that her son is taking medication for the seizure disorder. The nurse plans care, knowing that which of the following medications are used for long-term control of tonic-clonic seizures? - Gabapentin (Neurontin) Ethosuximide (Zarontin) Carbamazepine (Tegretol A CD4+ count has been prescribed for a child with human immunodeficiency virus (HIV) infection. The mother asks the nurse about the purpose of the test and why the test needs to be done if it is already known that the child has HIV. The nurse should provide which information to the mother? - The CD4+ count is used to determine the child's immune status. The CD4+ count is used to identify the risk for disease progression. The CD4+ count identifies the need for Pneumocystis jiroveci pneumonia prophylaxis after 1 year of age. The CD4 count is measured at ages 1 and 3 months, every 3 months until the age of 2 years, and at least every 6 months thereafter. More frequent monitoring of CD4+ counts is indicated when pneumonia prophylaxis and antiretroviral therapy are administered.A child with sickle cell anemia is being discharged after treatment for a crisis. Which instructions should the nurse provide to prevent another crisis from occurring? - Drink plenty of fluids. Wash hands before meals and after playing. Report a sore throat immediately. Sickle cell crisis can be precipitated by cold, dehydration, stress, or infection. Increasing the amount of fluids will reduce the viscosity of blood, thus preventing vascular occlusion. A conscious effort to wash hands can improve the child's health by preventing infection. A sore throat is a sign of an infection and must be reported. It is important to avoid cold temperatures of any kind because this can cause vasoocclusion. Folic acid avoidance is not necessary. Children need to be encouraged to set their own limits in play. A client asks the nurse to describe how her developing baby will get enough blood and oxygen. The nurse responds that the fetal circulatory system accomplishes this task by which of the following? - Carrying more oxygen on fetal hemoglobin than maternal hemoglobin Making the fetal cardiac output higher per unit of body weight than the maternal cardiac output Bypassing the fetal lungs to circulate oxygen rich blood Using the fetus's beating heart to pump blood in the circulatory system The fetal lungs do not function for respiratory gas exchange, so a special circulatory pathway, the ductus arteriosus, bypasses the lungs. A small amount of blood circulates through the resistant lung tissue, but the majority follows the path with less resistance through the ductus arteriosus into the aorta. The following three special characteristics enable the fetus to obtain sufficient oxygen from maternal blood: fetal hemoglobin carries 20% to 30% more oxygen than maternal hemoglobin; the hemoglobin concentration of the fetus is about 50% greater than that of the mother; and the fetal heart rate is 110 to 160 beats per minute, making the cardiac output per unit of body weight higher than that of an adult A client enters the emergency room confused, twitching, and having seizures. His family states he recently was placed on corticosteroids for arthritis and was feeling better and exercising daily. Upon assessment, he has flushed skin, dry mucous membranes, an elevated temperature, and poor skin turgor. His serum sodium level is 172 mEq/L. Choose the interventions that the health care provider would likely prescribe. - Monitor intake and output. Monitor the vital signs. Monitor the electrolyte levels. Increase water intake orally. Provide a sodium-reduced diet
