HESI Pediatrics Exam Hints

HESI Pediatrics Exam Hints Growth and Development Milestones When does birth length double? Answer: By 4 years When does the child sit unsupported? Answer: 8 months When does a child achieve 50% of adult height? Answer: 2 years When does a child throw a ball overhand? Answer: 18 months When does a child speak 2-3 wordsentences? Answer: 2 years When does a child use scissors? Answer: 4 years When does a child tie his/her shoes? Answer: 5 years Be aware that a girl’s growth spurt during adolescence begins earlier than boys (as early as 10 years old). Temper tantrums are common in the toddler, i.e., considered “normal,” or average behavior. Be aware that adolescences is a time when the child forms his/her identity and that rebellion against family values is common for this age group. Normal growth and development knowledge is used to evaluate interventions and therapy. For example, “What behavior would indicate that thyroid hormone therapy for a 4- month-old is effective?” You must know what milestones are accomplished by a 4- month-old. One correct answer would be “has steady control” which is an expected milestone for a 4month-old and indicates that replacement therapy is adequate for growth. Use facts and principles related to growth and development in planning teaching interventions. For example: “What task could a 5-year-old diabetic boy be expected to accomplish by himself?” One correct answer would be to pick the injection sites. This is possible for a preschooler to do and gives the child some sense of control. School-age children are in Erikson’s stage of industry, meaning they like to do and accomplish things. Peers are also becoming important for this age child. Age groups concepts of bodily injury: Infants: After 6 months, their cognitive development allows them to remember pain. Toddlers: Fear intrusive procedures. Preschoolers: Fear body mutilation. School age: Fear loss of control of their body. Adolescent: Major concern is change in body image. Pertinent history should be obtained prior to administering certain immunizations because reactions to previous immunizations or current health conditions may contraindicate current immunizations: DPT: History of seizures, neurological symptoms after previous vaccine, or systematic allergic reactions. MMR: History of anaphylactic reaction to eggs orneomycin. Pertussis fatalities continue to occur in unimmunized infants in the U.S. Subcutaneous injection, rather than intradermal, invalidates the Mantoux test. The common cold is not contraindication for immunization. Following immunization, what teaching should the nurse provide to the parents? Irritability, fever (<102 degrees F), redness and soreness at injection site for 2-3 days are normal side effects of DPT and IPV administration. Call health care provider if seizures, high fever, or high -pitched crying occur. A warm washcloth on the thigh injection site and “bicycling” the legs w/each diaper change will decrease soreness. Acetaminophen (Tylenol) is administered orally every 4-6 hours (10-15 mg/Kg). Children w/German measles pose a serious threat to their unborn siblings. The nurse should counsel all expectant mothers, especially those w/young children, to be aware of the serious consequences of exposure to German measles during pregnancy. Common childhood problems are encountered by nurses caring for children in the community or hospital settings. The child’s age directly influences the severity and management of these problems. Nutritional Assessment: Teach proper cooking and storage to preserve potency, i.e., cook vegetables in small amount of liquid. Store milk in opaque container. Add potassium to IV fluids ONLY w/adequate urine output. Urinary output for infants and children be 1-2 ml/kg/hour. Use of syrup of ipecac is no longer recommended by the American Academy of Pediatrics. Teach parents that it is NOT recommended to induce vomiting in any way as it may cause more damage. Child needs 150% of the usual calorie intake for normal growth and development. Do not examine the throat of a child w/epiglottitis due to the risk of completely obstructing the airway, i.e., do not put a tongue blade or any object in the throat. In planning and providing nursing care, a patent airways is always a priority of care, regardless of age! Respiratory disorders are the primary reason most children and their families seek medical care. Therefore, these disorders are frequently tested on the NCLEX-RN. Knowing the normal parameters for respiratory distress in children is essential! The nurses should be sure a PT and PTT have been determined prior to a tonsillectomy. More importantly, the nurse should ask if there has been a history of bleeding, prolonged/excessive, or if there is a history of any bleeding disorders in the family. When calculating a pediatric dosage, the nurse must often change the child’s weight from pounds to kilograms. HINT: Weight expressed in kilograms should always be a smaller number than weight expressed in pounds. Polycythemia is common in children w/cyanotic defects. For normal cardiac rates in children, see Respiratory in this chapter. The heart rate of a child will increase w/crying orfever. Infants may require tube feeding to conserve energy. Basic difference between cyanotic and acyanotic defects: Acyanotic: Has abnormal circulation, however, all blood entering the systemic circulation is oxygenated. Cyanotic: Has abnormal circulation w/unoxygenated blood entering systemic circulation. CHF: Congestive heart failure is more often associated w/acyanotic defects. CHF is a common complication of congenital heart disease. It reflects the increased workload of the heart resulting from shunts or obstructions. The two objectives in treating CHF are to reduce the workload of the heart and increase cardiac output. When frequent weighings are required, weigh client on the same scale at same time of day so that accurate comparisons can bemade. The nursing goal in caring for children w/Down syndrome is to help the child reach his/her OPTIMAL level of functioning. Feed infants or child w/cerebral palsy using nursing interventions aimed at preventing aspiration. Position child upright and support the lower jaw. The signs of increased ICP are the opposite of those of shock. Shock: Increased pulse, Decreased bloodpressure. Increased ICP: Decreased pulse, Increased blood pressure. Baseline data on the child’s USUAL behavior and level of development is essential so changes associated w/increased ICP can be detected EARLY. Do not pump shunt unless specifically prescribed. The shunt is made up of delicate valves, and pumping changes pressures within theventricles. Medication noncompliance is the most common cause of increased seizure activity. Do NOT use tongue blade, padded or not, during a seizure. It can cause traumatic damage to mouth/oral cavity. Monitor hydration status and IV therapy carefully. With meningitis, there may be inappropriate ADH secretions causing fluid retention (cerebral edema) and dilutional hyponatremia. Headache upon awakening is the most common presenting symptoms ofbrain tumors. Most postoperative clients w/infractentorial tumors are prescribed to lie flat and turn to either side. A large tumor may require that the child NOT be turned to the operative side. Suctioning, coughing, straining, and/or turning causes increased ICP. Decreased urinary output is FIRST sign of renal failure. Surgical correction for hypostasis is usually done before preschool years due to achieving sexual identity, castration anxiety, and toilet training. Typical parent/family reactions to a child w/an obvious malformation such as cleft lip/palate are guilt, disappointment, grief, sense of loss, and anger. Children w/cleft lip/palate and those w/pyloric stenosis both have a nursing diagnosis “alteration in nutrition; less than bodyrequirements.” Cleft lip/palate is related to decreased ability to suck. Pyloric stenosis is related to frequent vomiting. Nutritional needs and fluid and electrolyte balance are key problems for children w/GI disorders. The younger the child, the more vulnerable they are to fluid and electrolyte imbalances and greater is the need for caloric intake required for growth. Take axillary temperature on children w/congenital mega colon. REMEMBER the Hgb norms. Newborn: 14 to 24 g/dl Infant: 10 to 15 g/dl Child: 11 to 16 g/dl TEACH FAMILY ABOUT ADMINISTRATION OF ORAL IRON: Give on empty stomach (as tolerated for better absorption). Give w/citrus juices (vitamin C) for increased absorption. Use dropper or straw to avoid discoloringteeth. Stools will become tarry. Iron can be fatal in severe overdose; keep away from children. Don not give w/dairy products. Inherited bleeding disorders (hemophilia and sickle cell anemia) are often used to test knowledge of genetic transmission patterns. Remember: Autosomal recessive: Both parents must be heterozygous, or carriers of the recessive trait, for the disease to be expressed in their offspring. With each pregnancy, there is a 1:4 chance of the infant having the disease. However, all children of such parents CAN get the disease - NOT 25% of them. This is the transmission for sickle cell anemia, cystic fibrosis, and phenylketonuria (PKU). X-linked recessive trait: The trait is carried on the X chromosome, therefore, usually affects male offspring, e.g., hemophilia. With each pregnancy of a woman who is a carrier there is a 25% chance of having a child w/hemophilia. If the child is male, he has a 50% chance of having hemophilia. If the child is female, she has a 50% chance of being a carrier. Hydration is very important in treatment of sickle cell disease because it promotes hem dilution and circulation of red cells through the blood vessels. Important terms: Heterozygous gene (HgbAS) sickle cell trait. Homozygous gene (HbSS) sickle cell disease. Abnormal hemoglobin (HGBS) disease and trait. Supplemental iron is not given to clients w/sickle cell anemia. The anemia is not caused by iron deficiency. Folic acid is given orally to stimulate RBC synthesis. Have epinephrine and oxygen readily available to treat anaphylaxis when administering I-asparaginase. Prednisone is frequently used in combination w/antineoplastic drugs to reduce the mitosis of lymphocytes. Allopurinol, a xanthine-oxidase inhibitor, is also administered to prevent renal damage from uric acid build up during cellular lysis. An infant w/hypothyroidism is often described as a “good, quiet baby” by the parents. Early detection of hypothyroidism and phenylketonuria is essential in preventing mental retardation in infants. Knowledge of normal growth and development is important, since a lack of attainment can be used to detect the existence of these metabolic/endocrine disorders and attainment can be used for evaluating the treatment’s effect. NutraSweet (aspartame) contains phenylalanine and should not therefore, be given to a child w/phenylketonuria. Diabetes mellitus (DM) in children was typically diagnosed as insulin dependant diabetes (Type 1) until recently. A marked increase in type 2 DM has occurred recently in the U.S., particularly among Native-American, African-American, and Hispanic children and adolescents. Adolescence frequently causes difficulty w/management since growth is rapid and the need to be like peers makes compliance difficult. Remember to consider the child’s age, cognitive level of development, and psychosocial development when answering NCLEX-RN questions. When child is in ketoacidosis, administer regular insulin IV as prescribed in normal saline. There has been an increase in the number of children diagnosed with Type 2 diabetes. The increasing rate of obesity in children is thought to be a contributing factor. Other contributing factors include lack of physical activity and a family history of Type 2 diabetes. Fractures in older children are common as they fall during play and are involved in motor vehicle accidents. Spiral fractures (caused by twisting) and fractures in infants may be related to child abuse. Fractures involving the epiphyseal plate (growth plate) can have serious consequences in terms of growth of the affected limb. Skin traction for fracture reduction should NOT be removed unless prescribed by healthcare provider. Pin sites can be sources of infection. Monitor for signs of infection. Cleanse and dress pin sites as prescribed. Skeletal disorders affect the infant’s or child’s physical mobility, and typical NCLEX- RN questions focus on appropriate toys or activities for the child who is on bedrest and/or immobilized. Children do not like injections and will deny pain to avoid “shots.” A brace does not correct the curve of a child w/scoliosis, it only stops or slows the progression. Corticosteroids are used short term in low doses during exacerbations. Long-term use is avoided due to side effects and their adverse effect on growth.
