A family who excludes meat from their diet but consumes dairy products would be referred to as ________________________ vegetarians.
ANS: Lacto-ovo Lacto-ovo vegetarians consume dairy products and occasionally fish. A well planned vegetarian diet is adequate for all stages of the life cycle and promotes normal growth.
The nurse is assessing a child after a cardiac catheterization. Which complication should the nurse be assessing for? a. Cardiac arrhythmia b. Hypostatic pneumonia c. Heart failure d. Rapidly increasing blood pressure
ANS: A Because a catheter is introduced into the heart, a risk exists of catheter-induced dysrhythmias occurring during the procedure. These are usually transient. Hypostatic pneumonia, heart failure, and rapidly increasing blood pressure are not risks usually associated with cardiac catheterization.
Which is an important nursing consideration in the care of a child with celiac disease? a. Refer to a nutritionist for detailed dietary instructions and education. b. Help child and family understand that diet restrictions are usually only temporary. c. Teach proper hand washing and standard precautions to prevent disease transmission. d. Suggest ways to cope more effectively with stress to minimize symptoms.
ANS: A The main consideration is helping the child adhere to dietary management. Considerable time is spent explaining to the child and parents about the disease process, the specific role of gluten in aggravating the condition, and foods that must be restricted. Referral to a nutritionist would help in this process. The most severe symptoms usually occur in early childhood and adult life. Dietary avoidance of gluten should be lifelong. Celiac disease is not transmissible or stress related.

Suggest ways to cope more effectively with stress to minimize symptoms.
ANS: A The main consideration is helping the child adhere to dietary management. Considerable time is spent in explaining to the child and parents the disease process, the specific role of gluten in aggravating the condition, and those foods that must be restricted. Referral to a nutritionist would help in this process. The most severe symptoms usually occur in early childhood and adult life. Dietary avoidance of gluten should be lifelong. Celiac disease is not transmissible or stress related.
The nurse is talking to a parent of an infant with heart failure about feeding the infant. Which statement about feeding the child is correct? a. "You may need to increase the caloric density of your infant's formula." b. "You should feed your baby every 2 hours." c. "You may need to increase the amount of formula your infant eats with each feeding." d. "You should place a nasal oxygen cannula on your infant during and after each feeding."
ANS: A The metabolic rate of infants with heart failure is greater because of poor cardiac function and increased heart and respiratory rates. Their caloric needs are greater than those of the average infants, yet their ability to take in the calories is diminished by their fatigue. Infants with heart failure should be fed every 3 hours; a 2-hour schedule does not allow for enough rest, and a 4-hour schedule is too long. Fluids must be carefully monitored because of the heart failure. Infants do not require supplemental oxygen with feedings.
25. The best chance of survival for a child with cirrhosis is: a.Liver transplantation. b.Treatment with corticosteroids. c.Treatment with immune globulin. d.Provision of nutritional support.
ANS: A The only successful treatment for end-stage liver disease and liver failure may be liver transplantation, which has improved the prognosis for many children with cirrhosis. Liver transplantation has revolutionized the approach to cirrhosis. Liver failure and cirrhosis are indications for transplantation. Liver transplantation reflects the failure of other medical and surgical measures to prevent or treat cirrhosis.

The nurse is conducting an admission assessment on a school-age child with acute renal failure. Which are the primary clinical manifestations the nurse expects to find with this condition? a. Oliguria and hypertension b. Hematuria and pallor c. Proteinuria and muscle cramps d. Bacteriuria and facial edema
ANS: A The principal feature of acute renal failure is oliguria; hypertension is a nonspecific clinical manifestation. Hematuria and pallor, proteinuria and muscle cramps, and bacteriuria and facial edema are not principal features of acute renal failure.
23. Bismuth subsalicylate, clarithromycin, and metronidazole are prescribed for a child with a peptic ulcer to: a.Eradicate Helicobacter pylori. b.Coat gastric mucosa. c.Treat epigastric pain. d.Reduce gastric acid production.
ANS: A This combination of drug therapy is effective in the treatment and eradication of H. pylori.
Which is instituted for the therapeutic management of minimal change nephrotic syndrome? a. Corticosteroids b. Antihypertensive agents c. Long-term diuretics d. Increased fluids to promote diuresis
ANS: A Corticosteroids are the first line of therapy for minimal change nephrotic syndrome. Response is usually seen within 7 to 21 days. Antihypertensive agents and long-term diuretic therapy are usually not necessary. A diet that has fluid and salt restrictions may be indicated.
Which should the nurse recommend to prevent urinary tract infections in young girls? a. Wear cotton underpants. b. Limit bathing as much as possible. c. Increase fluids; decrease salt intake. d. Cleanse perineum with water after voiding.
ANS: A Cotton underpants are preferable to nylon underpants. No evidence exists that limiting bathing, increasing fluids/decreasing salt intake, or cleansing the perineum with water after voiding decrease urinary tract infections in young girls.
1. Nurses must be alert for increased fluid requirements when a child has: a.Fever. b.Mechanical ventilation. c.Congestive heart failure. d.Increased intracranial pressure (ICP).
ANS: A Fever leads to great insensible fluid loss in young children because of increased body surface area relative to fluid volume. Respiratory rate influences insensible fluid loss and should be monitored in the mechanically ventilated child. Congestive heart failure is a case of fluid overload in children. ICP does not lead to increased fluid requirements in children.
A hospitalized child with minimal change nephrotic syndrome is receiving high doses of prednisone. Which is an appropriate nursing goal related to this? a. Prevent infection. b. Stimulate appetite. c. Detect evidence of edema. d. Ensure compliance with prophylactic antibiotic therapy.
ANS: A High-dose steroid therapy has an immunosuppressant effect. These children are particularly vulnerable to upper respiratory tract infections. A priority nursing goal is to minimize the risk of infection by protecting the child from contact with infectious individuals. Appetite is increased with prednisone therapy. The amount of edema should be monitored as part of the disease process, not necessarily related to the administration of prednisone. Antibiotics would not be used as prophylaxis.
A young child is brought to the emergency department with severe dehydration secondary to acute diarrhea and vomiting. Therapeutic management of this child should begin with: a. intravenous (IV) fluids. b. ORS. c. clear liquids, 1 to 2 ounces at a time. d. administration of antidiarrheal medication.
ANS: A In children with severe dehydration, IV fluids are initiated. ORS is acceptable therapy if the dehydration is not severe. Diarrhea is not managed by using clear liquids by mouth. These fluids have a high carbohydrate content, low electrolyte content, and high osmolality. Antidiarrheal medications are not recommended for the treatment of acute infectious diarrhea.
The nurse closely monitors the temperature of a child with minimal change nephrotic syndrome. The purpose of this assessment is to detect an early sign of which possible complication? a. Infection b. Hypertension c. Encephalopathy d. Edema
ANS: A Infection is a constant source of danger to edematous children and those receiving corticosteroid therapy. An increased temperature could be an indication of an infection. Temperature is not an indication of hypertension or edema. Encephalopathy is not a complication usually associated with minimal change nephrotic syndrome. The child will most likely have neurologic signs and symptoms.
10. A young child is brought to the emergency department with severe dehydration secondary to acute diarrhea and vomiting. Therapeutic management of this child will begin with: a.Intravenous fluids. b.Oral rehydration solution (ORS). c.Clear liquids, 1 to 2 ounces at a time. d.Administration of antidiarrheal medication.
ANS: A Intravenous fluids are initiated in children with severe dehydration. ORS is acceptable therapy if the dehydration is not severe. Diarrhea is not managed by using clear liquids by mouth. These fluids have a high carbohydrate content, low electrolyte content, and high osmolality. Antidiarrheal medications are not recommended for the treatment of acute infectious diarrhea.
Which type of dehydration is defined as "dehydration that occurs in conditions in which electrolyte and water deficits are present in approximately balanced proportion"? a. Isotonic dehydration b. Hypotonic dehydration c. Hypertonic dehydration d. All types of dehydration in infants and small children
ANS: A Isotonic dehydration is the correct term for this definition and is the most frequent form of dehydration in children. Hypotonic dehydration occurs when the electrolyte deficit exceeds the water deficit, leaving the serum hypotonic. Hypertonic dehydration results from water loss in excess of electrolyte loss and is usually caused by a proportionately larger loss of water or a larger intake of electrolytes. This definition is specific to isotonic dehydration.
A nurse is admitting an infant with biliary atresia. Which is the earliest clinical manifestation of biliary atresia the nurse should expect to assess? a. Jaundice b. Vomiting c. Hepatomegaly d. Absence of stooling
ANS: A Jaundice is the earliest and most striking manifestation of biliary atresia. It is first observed in the sclera, may be present at birth, but is usually not apparent until age 2 to 3 weeks. Vomiting is not associated with biliary atresia. Hepatomegaly and abdominal distention are common but occur later. Stools are large and lighter in color than expected because of the lack of bile
26. The earliest clinical manifestation of biliary atresia is: a.Jaundice. b.Vomiting. c.Hepatomegaly. d.Absence of stooling.
ANS: A Jaundice is the earliest and most striking manifestation of biliary atresia. It is first observed in the sclera, may be present at birth, but is usually not apparent until ages 2 to 3 weeks. Vomiting is not associated with biliary atresia. Hepatomegaly and abdominal distention are common but occur later. Stools are large and lighter in color than expected because of the lack of bile.
Which painful, tender, pea-sized nodules may appear on the pads of the fingers or toes in bacterial endocarditis? a. Osler nodes b. Janeway lesions c. Subcutaneous nodules d. Aschoff nodes
ANS: A Osler nodes are red, painful, intradermal nodes found on pads of the phalanges in bacterial endocarditis. Janeway lesions are painless hemorrhagic areas on palms and soles in bacterial endocarditis. Subcutaneous nodules are nontender swellings, located over bony prominences, commonly found in rheumatic fever. Aschoff nodules are small nodules composed of cells and leukocytes found in the interstitial tissues of the heart in rheumatic myocarditis.
The nurse is caring for a boy with probable intussusception. He had diarrhea before admission but, while waiting for administration of air pressure to reduce the intussusception, he passes a normal brown stool. Which nursing action is the most appropriate? a. Notify practitioner. b. Measure abdominal girth. c. Auscultate for bowel sounds. d. Take vital signs, including blood pressure.
ANS: A Passage of a normal brown stool indicates that the intussusception has reduced itself. This is immediately reported to the practitioner, who may choose to alter the diagnostic-therapeutic care plan. The first action would be to report the normal stool to the practitioner.
33. The nurse is caring for a boy with probable intussusception.

Notify the practitioner. b. Measure abdominal girth. c. Auscultate for bowel sounds. d. Take vital signs, including blood pressure.
ANS: A Passage of a normal brown stool indicates that the intussusception has reduced itself. This is immediately reported to the practitioner, who may choose to alter the diagnostic/therapeutic plan of care.
The nurse is conducting a staff in-service on childhood-acquired heart diseases. Which is a major clinical manifestation of rheumatic fever? a. Polyarthritis b. Osler nodes c. Janeway spots d. Splinter hemorrhages of distal third of nails
ANS: A Polyarthritis, which is swollen, hot, red, and painful joints, is a major clinical manifestation of rheumatic fever. The affected joints will change every 1 to 2 days. Primarily the large joints are affected. Osler nodes, Janeway spots, and splinter hemorrhages are characteristic of infective endocarditis.
12. A high-fiber food that the nurse could recommend for a child with chronic constipation is: a.Popcorn. c.Muffins. b.Pancakes. d.Ripe bananas.
ANS: A Popcorn is a high-fiber food. Cake does not have significant fiber unless made with fruit or bran. Raw fruits, especially those with skins and seeds and other than ripe bananas and avocado, are high in fiber.
Which is a high-fiber food that the nurse should recommend for a child with chronic constipation? a. Popcorn b. Pancakes c. Muffins d. Ripe bananas
ANS: A Popcorn is a high-fiber food. Pancakes and muffins do not have significant fiber unless made with fruit or bran. Raw fruits, especially those with skins and seeds, other than ripe bananas, have high fiber
The nurse is conducting an assessment on a school-age child with urosepsis. Which assessment finding should the nurse expect? a. Fever with a positive blood culture b. Proteinuria and edema c. Oliguria and hypertension d. Anemia and thrombocytopenia
ANS: A Symptoms of urosepsis include a febrile UTI coexisting with systemic signs of bacterial illness; blood culture reveals presence of urinary pathogen. Proteinuria and edema are symptoms of minimal change nephrotic syndrome (MCNS). Oliguria and hypertension are symptoms of acute glomerulonephritis (AGN). Anemia and thrombocytopenia are symptoms of hemolytic uremic syndrome (HUS).
Parents of a 3-year-old child with congenital heart disease are afraid to let their child play with other children because of possible overexertion. The nurse's reply should be based on which statement? a. Child needs opportunities to play with peers. b. Child needs to understand that peers' activities are too strenuous. c. Parents can meet all of the child's needs. d. Constant parental supervision is needed to avoid overexertion.
ANS: A The child needs opportunities for social development. Children usually limit their activities if allowed to set their own pace. The child will limit activities as necessary. Parents must be encouraged to seek appropriate social activities for the child, especially before kindergarten. The child needs to have activities that foster independence. The child will be able to regulate activities.
A child has recurrent abdominal pain (RAP) and a dairy-free diet has been prescribed for 2 weeks. Which explanation is the reason for prescribing a dairy-free diet? a. To rule out lactose intolerance b. To rule out celiac disease c. To rule out sensitivity to high sugar content d. To rule out peptic ulcer disease
ANS: A Treatment for RAP involves providing reassurance and reducing or eliminating symptoms. Dietary modifications may include removal of dairy products to rule out lactose intolerance. Fructose is eliminated to rule out sensitivity to high sugar content and gluten is removed to rule out celiac disease. A dairy-free diet would not rule out peptic ulcer disease.
When a child has chronic renal failure, the progressive deterioration produces a variety of clinical and biochemical disturbances that eventually are manifested in the clinical syndrome known as: a. uremia. b. oliguria. c. proteinuria. d. pyelonephritis
ANS: A Uremia is the retention of nitrogenous products, producing toxic symptoms. Oliguria is diminished urinary output. Proteinuria is the presence of protein, usually albumin, in the urine. Pyelonephritis is an inflammation of the kidney and renal pelvis.
The nurse is caring for a neonate with a suspected tracheoesophageal fistula. Nursing care should include: a. elevating the head but give nothing by mouth. b. elevating the head for feedings. c. feeding glucose water only. d. avoiding suctioning unless infant is cyanotic.
ANS: A When a newborn is suspected of having a tracheoesophageal fistula, the most desirable position is supine with the head elevated on an inclined plane of at least 30 degrees. It is imperative that any source of aspiration be removed at once; oral feedings are withheld. Feedings should not be given to infants suspected of having tracheoesophageal fistulas. The oral pharynx should be kept clear of secretion by oral suctioning. This is to prevent the cyanosis that is usually the result of laryngospasm caused by overflow of saliva into the larynx.

A child who has just had definitive repair of a high rectal malformation is to be discharged. Which should the nurse address in the discharge preparation of this family? (Select all that apply.) a. Perineal and wound care b. Necessity of firm stools to keep suture line clean c. Bowel training beginning as soon as child returns home d. Reporting any changes in stooling patterns to practitioner e. Use of diet modification to prevent constipation
ANS: A, D, E Wound care instruction is necessary in a child who is being discharged after surgery. The parents are taught to notify the practitioner if any signs of an anal stricture or other complications develop. Constipation is avoided, since a firm stool will place strain on the suture line. Fiber and stool softeners are often given to keep stools soft and avoid tension on the suture line. The child needs to recover from the surgical procedure. Then bowel training may begin, depending on the child's developmental and physiologic readiness.
4. Acute diarrhea is often caused by: a.Celiac disease. b.Antibiotic therapy. c.Immunodeficiency. d.Protein malnutrition.
ANS: B Acute diarrhea is a sudden increase in frequency and change in consistency of stools and may be associated with antibiotic therapy. Hirschsprung's disease, hypothyroidism, and meconium ileus are usually manifested with constipation rather than diarrhea.
Which best describes acute glomerulonephritis? a. Occurs after a urinary tract infection b. Occurs after a streptococcal infection c. Associated with renal vascular disorders d. Associated with structural anomalies of genitourinary tract
ANS: B Acute glomerulonephritis is an immune-complex disease that occurs after a streptococcal infection with certain strains of the group A â-hemolytic streptococcus. Acute glomerulonephritis usually follows streptococcal pharyngitis and is not associated with renal vascular disorders or genitourinary tract structural anomalies.
An infant with short bowel syndrome will be discharged home on total parenteral nutrition (TPN) and gastrostomy feedings. Nursing care should include: a. preparing family for impending death. b. teaching family signs of central venous catheter infection. c. teaching family how to calculate caloric needs. d. securing TPN and gastrostomy tubing under diaper to lessen risk of dislodgment.
ANS: B During TPN therapy, care must be taken to minimize the risk of complications related to the central venous access device, such as catheter infections, occlusions, or accidental removal. This is an important part of family teaching. The prognosis for patients with short bowel syndrome depends in part on the length of residual small intestine. It has improved with advances in TPN. Although parents need to be taught about nutritional needs, the caloric needs and prescribed TPN and rate are the responsibility of the health care team. The tubes should not be placed under the diaper due to risk of infection.
Pyloric stenosis can best be described as: a. dilation of the pylorus. b. hypertrophy of the pyloric muscle. c. hypotonicity of the pyloric muscle. d. reduction of tone in the pyloric muscle.
ANS: B Hypertrophic pyloric stenosis occurs when the circumferential muscle of the pyloric sphincter becomes thickened, resulting in elongation and narrowing of the pyloric channel. Dilation of the pylorus, hypotonicity of the pyloric muscle, and reduction of tone in the pyloric muscle are not the definition of pyloric stenosis.
Which occurs in septic shock? a. Hypothermia b. Increased cardiac output c. Vasoconstriction d. Angioneurotic edema
ANS: B Increased cardiac output, which results in warm, flushed skin, is one of the manifestations of septic shock. Fever and chills are characteristic of septic shock. Vasodilation is more common than vasoconstriction. Angioneurotic edema occurs as a manifestation in anaphylactic shock.
Enemas are ordered to empty the bowel preoperatively for a child with Hirschsprung disease. The enema solution should be: a. tap water. b. normal saline. c. oil retention. d. phosphate preparation.
ANS: B Isotonic solutions should be used in children. Saline is the solution of choice. Plain water is not used. This is a hypotonic solution and can cause rapid fluid shift, resulting in fluid overload. Oil-retention enemas will not achieve the "until clear" result. Phosphate enemas are not advised for children because of the harsh action of the ingredients. The osmotic effects of the phosphate enema can result in diarrhea, which can lead to metabolic acidosis.
16. A 4-month-old infant has gastroesophageal reflux disease (GERD) but is thriving without other complications. What should the nurse suggest to minimize reflux? a.Place in Trendelenburg position after eating. b.Thicken formula with rice cereal. c.Give continuous nasogastric tube feedings. d.Give larger, less frequent feedings.
ANS: B Small frequent feedings of formula combined with 1 teaspoon to 1 tablespoon of rice cereal per ounce of formula has been recommended. Milk thickening agents have been shown to decrease the number of episodes of vomiting and increase the caloric density of the formula. This may benefit infants who are underweight as a result of GERD. Placing the child in a Trendelenburg position would increase the reflux. Continuous nasogastric feedings are reserved for infants with severe reflux and failure to thrive. Smaller, more frequent feedings are recommended in reflux.

The nurse is preparing an adolescent for discharge after a cardiac catheterization. Which statement by the adolescent would indicate a need for further teaching? a. "I should avoid tub baths but may shower." b. "I have to stay on strict bed rest for 3 days." c. "I should remove the pressure dressing the day after the procedure." d. "I may attend school but should avoid exercise for several days."
ANS: B The child does not need to be on strict bed rest for 3 days. Showers are recommended; children should avoid a tub bath. The pressure dressing is removed the day after the catheterization and replaced by an adhesive bandage to keep the area clean. Strenuous activity must be avoided for several days, but the child can return to school.
The nurse is caring for a child admitted with acute abdominal pain and possible appendicitis. Which is appropriate to relieve the abdominal discomfort? a. Place in Trendelenburg position. b. Allow to assume position of comfort. c. Apply moist heat to the abdomen. d. Administer a saline enema to cleanse bowel.
ANS: B The child should be allowed to take a position of comfort, usually with the legs flexed. The Trendelenburg position will not help with the discomfort. In any instance in which appendicitis is a possibility, there is a danger in administering a laxative or enemas or applying heat to the area. Such measures stimulate bowel motility and increase the risk of perforation.
A mother who intended to breastfeed has given birth to an infant with a cleft palate. Nursing interventions should include: a. giving medication to suppress lactation. b. encouraging and helping mother to breastfeed. c. teaching mother to feed breast milk by gavage. d. recommending use of a breast pump to maintain lactation until infant can suck.
ANS: B The mother who wishes to breastfeed may need encouragement and support because the defect does present some logistical issues. The nipple must be positioned and stabilized well back in the infant's oral cavity so that the tongue action facilitates milk expression. Because breastfeeding is an option, if the mother wishes to breastfeed, medications should not be given to suppress lactation. Because breastfeeding can usually be accomplished, gavage feedings are not indicated. The suction required to stimulate milk, absent initially, may be useful before nursing to stimulate the let-down reflex
Which is an objective of care for a 10-year-old child with minimal change nephrotic syndrome? a. Reduce blood pressure. b. Reduce excretion of urinary protein. c. Increase excretion of urinary protein. d. Increase ability of tissues to retain fluid.
ANS: B The objectives of therapy for the child with minimal change nephrotic syndrome include reduction of the excretion of urinary protein, reduction of fluid retention, prevention of infection, and minimization of complications associated with therapy. Blood pressure is usually not elevated in minimal change nephrotic syndrome. Excretion of urinary protein and fluid retention are part of the disease process and must be reversed.
The nurse is teaching parents about prevention of urinary tract infections in children. Which factor predisposes the urinary tract to infection? a. Increased fluid intake b. Short urethra in young girls c. Prostatic secretions in males d. Frequent emptying of the bladder
ANS: B The short urethra in females provides a ready pathway for invasion of organisms. Increased fluid intake and frequent emptying of the bladder offer protective measures against urinary tract infections. Prostatic secretions have antibacterial properties that inhibit bacteria.
29. The nurse is caring for an infant whose cleft lip was repaired. Important aspects of this infant's postoperative care include: a. Arm restraints, postural drainage, mouth irrigations. b. Cleansing suture line, supine and side-lying positions, arm restraints. c. Mouth irrigations, prone position, cleansing suture line. d. Supine and side-lying positions, postural drainage, arm restraints.
ANS: B The suture line should be cleansed gently after feeding. The child should be positioned on back or side or in infant seat. Elbows are restrained to prevent the child from accessing the operative site. Postural drainage is not indicated. This would increase the pressure on the operative site when the child is placed in different positions. Mouth irrigations would not be indicated.

ANS: B The suture line should be cleansed gently after feeding. The child should be positioned on the back, on the side, or in an infant seat. Elbows are restrained to prevent the child from accessing the operative site. Postural drainage is not indicated. This would increase the pressure on the operative site when the child is placed in different positions. There is no reason to perform mouth irrigations, and the child should not be placed in the prone position where injury to the suture site can occur.
3. An infant is brought to the emergency department with poor skin turgor, weight loss, lethargy, and tachycardia. This is suggestive of: a.Overhydration. b.Dehydration. c.Sodium excess. d.Potassium excess.
ANS: B These clinical manifestations indicate dehydration. Symptoms of overhydration are edema and weight gain. Regardless of extracellular sodium levels, total body sodium is usually depleted in dehydration. Symptoms of hypocalcemia are a result of neuromuscular irritability and manifest as jitteriness, tetany, tremors, and muscle twitching.
Which vaccine is now recommended for the immunization of all newborns? a. Hepatitis A vaccine b. Hepatitis B vaccine c. Hepatitis C vaccine d. Hepatitis A, B, and C vaccines
ANS: B Universal vaccination for hepatitis B is now recommended for all newborns. A vaccine is available for hepatitis A, but it is not yet universally recommended. No vaccine is currently available for hepatitis C. Only hepatitis B vaccine is recommended for newborns.
A child is admitted with acute glomerulonephritis. The nurse should expect the urinalysis during this acute phase to show: a. bacteriuria, hematuria. b. hematuria, proteinuria. c. bacteriuria, increased specific gravity. d. proteinuria, decreased specific gravity.
ANS: B Urinalysis during the acute phase characteristically shows hematuria and proteinuria. Bacteriuria and changes in specific gravity are not usually present during the acute phase.
The nurse is teaching parents about signs of digoxin (Lanoxin) toxicity. Which is a common sign of digoxin toxicity? a. Seizures b. Vomiting c. Bradypnea d. Tachycardia
ANS: B Vomiting is a common sign of digoxin toxicity. Seizures are not associated with digoxin toxicity. The child will have a slower heart rate, not respiratory rate. The heart rate will be slower, not faster.
Which is true concerning hepatitis B? (Select all that apply.) a. Hepatitis B cannot exist in carrier state. b. Hepatitis B can be prevented by HBV vaccine. c. Hepatitis B can be transferred to an infant of a breastfeeding mother. d. Onset of hepatitis B is insidious. e. Principal mode of transmission for hepatitis B is fecal-oral route. f. Immunity to hepatitis B occurs after one attack.
ANS: B, C, D, F The vaccine elicits the formation of an antibody to the hepatitis B surface antigen, which is protective against hepatitis B. Hepatitis B can be transferred to an infant of a breastfeeding mother, especially if the mother's nipples are cracked. The onset of hepatitis B is insidious. Immunity develops after one exposure to hepatitis B. Hepatitis B has a carrier state. The fecal-oral route is the principal mode of transmission for hepatitis A. Hepatitis B is transmitted through the parenteral route.
1. What is true concerning hepatitis B? Choose all that apply. a. Hepatitis B cannot exist in a carrier state. b. Hepatitis B can be prevented by hepatitis B virus vaccine. c. Hepatitis B can be transferred to an infant of a breastfeeding mother. d. The onset of hepatitis B is insidious. e. The principal mode of transmission for hepatitis B is the fecal-oral route. f. Immunity to hepatitis B occurs after one attack.

Hepatitis B can be transferred to an infant of a breastfeeding mother, especially if the mother's nipples are cracked. The onset of hepatitis B is insidious. Immunity develops after one exposure to hepatitis B. These statements are not true concerning hepatitis B.
Nursing interventions for the child after a cardiac catheterization should include which actions? (Select all that apply.) a. Allow ambulation as tolerated. b. Monitor vital signs every 2 hours. c. Assess the affected extremity for temperature and color. d. Check pulses above the catheterization site for equality and symmetry. e. Remove pressure dressing after 4 hours. f. Maintain a patent peripheral intravenous catheter until discharge
ANS: C, F The extremity that was used for access for the cardiac catheterization must be checked for temperature and color. Coolness and blanching may indicate arterial occlusion. The child should have a patent peripheral intravenous line (PIV) to ensure adequate hydration. The child should remain on bed rest with the leg extended for a minimum of 4 hours. Initially vital signs are taken every 15 minutes, with emphasis on a heart rate counted for 1 minute. Pulses above the catheterization site should not be affected by the catheterization. Pulses distal to the site should be monitored. The pressure dressings should n
31. Which type of hernia has an impaired blood supply to the herniated organ? a. Hiatal hernia c. Omphalocele b. Incarcerated hernia d. Strangulated hernia
ANS: D A strangulated hernia is one in which the blood supply to the herniated organ is impaired. A hiatal hernia is the intrusion of an abdominal structure, usually the stomach, through the esophageal hiatus. An incarcerated hernia is a hernia that cannot be reduced easily. Omphalocele is the protrusion of intraabdominal viscera into the base of the umbilical cord. The sac is covered with peritoneum and not skin.

ANS: D A strangulated hernia is one in which the blood supply to the herniated organ is impaired. Hiatal hernia is the intrusion of an abdominal structure, usually the stomach, through the esophageal hiatus. Incarcerated hernia is a hernia that cannot be reduced easily. Omphalocele is the protrusion of intra-abdominal viscera into the base of the umbilical cord. The sac is covered with peritoneum, not skin.
A mother asks the nurse what would be the first indication that acute glomerulonephritis is improving. The nurse's best response should be that the: a. blood pressure will stabilize. b. the child will have more energy. c. urine will be free of protein. d. urinary output will increase.
ANS: D An increase in urinary output may signal resolution of the acute glomerulonephritis. If blood pressure is elevated, stabilization usually occurs with the improvement in renal function. The child having more energy and the urine being free of protein are related to the improvement in urinary output.
Which is a common, serious complication of rheumatic fever? a. Seizures b. Cardiac arrhythmias c. Pulmonary hypertension d. Cardiac valve damage
ANS: D Cardiac valve damage is the most significant complication of rheumatic fever. Seizures, cardiac arrhythmias, and pulmonary hypertension are not common complications of rheumatic fever.
Which clinical manifestation would be seen in a child with chronic renal failure? a. Hypotension b. Massive hematuria c. Hypokalemia d. Unpleasant "uremic" breath odor
ANS: D Children with chronic renal failure have a characteristic breath odor resulting from the retention of waste products. Hypertension may be a complication of chronic renal failure. With chronic renal failure, little or no urinary output occurs. Hyperkalemia is a concern in chronic renal failure.
Which clinical manifestation should the nurse expect to see as shock progresses in a child and becomes decompensated shock? a. Thirst b. Irritability c. Apprehension d. Confusion and somnolence
ANS: D Confusion and somnolence are beginning signs of decompensated shock. Thirst, irritability, and apprehension are signs of compensated shock.
The nurse is admitting a newborn with hypospadias to the nursery. The nurse expects which finding in this newborn? a. Absence of a urethral opening is noted. b. Penis appears shorter than usual for age. c. The urethral opening is along the dorsal surface of the penis. d. The urethral opening is along the ventral surface of the penis.
ANS: D Hypospadias is a congenital condition in which the urethral opening is located anywhere along the ventral surface of the penis. The urethral opening is present, but not at the glans. Hypospadias refers to the urethral opening, not to the size of the penis. Urethral opening along ventral surface of penis is known as epispadias.
The nurse is caring for a school-age child who has had a cardiac catheterization. The child tells the nurse that the bandage is "too wet." The nurse finds the bandage and bed soaked with blood. The most appropriate initial nursing action is to: a. notify physician. b. apply new bandage with more pressure. c. place the child in Trendelenburg position. d. apply direct pressure above catheterization site.
ANS: D If bleeding occurs, direct continuous pressure is applied 2.5 cm (1 inch) above the percutaneous skin site to localize pressure over the vessel puncture. Notifying a physician and applying a new bandage can be done after pressure is applied. The nurse can have someone else notify the physician while the pressure is being maintained. It is not a helpful intervention to place the girl in the Trendelenburg position. It would increase the drainage from the lower extremities.
43. An infant with pyloric stenosis experiences excessive vomiting that can result in: a. hyperchloremia. b. hypernatremia. c. metabolic acidosis. d. metabolic alkalosis.
ANS: D Infants with excessive vomiting are prone to metabolic alkalosis from the loss of hydrogen ions. Chloride ions and sodium are lost with vomiting. Metabolic alkalosis, not acidosis, is likely.
Invagination of one segment of bowel within another is called: a. atresia. b. stenosis. c. herniation. d. intussusception.
ANS: D Intussusception occurs when a proximal section of the bowel telescopes into a more distal segment, pulling the mesentery with it. The mesentery is compressed and angled, resulting in lymphatic and venous obstruction. Invagination of one segment of bowel within another is the definition of intussusception, not atresia, stenosis, or herniation.
Which therapeutic management treatment is implemented for children with Hirschsprung disease? a. Daily enemas b. Low-fiber diet c. Permanent colostomy d. Surgical removal of affected section of bowel
ANS: D Most children with Hirschsprung disease require surgical rather than medical management. Surgery is done to remove the aganglionic portion of the bowel, relieve obstruction, and restore normal bowel motility and function of the internal anal sphincter. Preoperative management may include enemas and low-fiber, high-calorie, high-protein diet, until the child is physically ready for surgery. The colostomy that is created in Hirschsprung disease is usually temporary.
13. Therapeutic management of most children with Hirschsprung's disease is primarily: a.Daily enemas. b.Low-fiber diet. c.Permanent colostomy. d.Surgical removal of affected section of bowel

child is admitted with bacterial gastroenteritis. Which lab results of a stool specimen confirm this diagnosis? a. Eosinophils b. Occult blood c. pH less than 6 d. Neutrophils and red blood cells
ANS: D Neutrophils and red blood cells in stool indicate bacterial gastroenteritis. Protein intolerance and parasitic infections are suspected in the presence of eosinophils. Occult blood may indicate pathogens such as Shigella, Campylobacter, or hemorrhagic Escherichia coli strains. A pH of less than 6 may indicate carbohydrate malabsorption or secondary lactase insufficiency.
7. A stool specimen from a child with diarrhea shows the presence of neutrophils and red blood cells. This is most suggestive of which condition? a.Protein intolerance b.Parasitic infection c.Fat malabsorption d.Bacterial gastroenteritis
ANS: D Neutrophils and red blood cells in stool indicate bacterial gastroenteritis. Protein intolerance is suspected in the presence of eosinophils. Parasitic infection is indicated by eosinophils. Fat malabsorption is indicated by foul-smelling, greasy, bulky stools.
The nurse is caring for an adolescent who has just started dialysis. The child seems always angry, hostile, or depressed. The nurse should recognize that this is most likely related to: a. neurologic manifestations that occur with dialysis. b. physiologic manifestations of renal disease. c. adolescents having few coping mechanisms. d. adolescents often resenting the control and enforced dependence imposed by dialysis
ANS: D Older children and adolescents need control. The necessity of dialysis forces the adolescent into a dependent relationship, which results in these behaviors. These are a function of the child's age, not neurologic or physiologic manifestations of the dialysis. Feelings of anger, hostility, and depression are functions of the child's age, not neurologic or physiologic manifestations of the dialysis. Adolescents do have coping mechanisms, but they need to have some control over their disease management
18. Which clinical manifestation would most suggest acute appendicitis? a.Rebound tenderness b.Bright red or dark red rectal bleeding c.Abdominal pain that is relieved by eating d.Abdominal pain that is most intense at McBurney point
ANS: D Pain is the cardinal feature. It is initially generalized and usually periumbilical. The pain localizes to the right lower quadrant at McBurney point. Rebound tenderness is not a reliable sign and is extremely painful to the child. Abdominal pain that is relieved by eating and is most intense at McBurney point are not signs of acute appendicitis.
Which clinical manifestation would be the most suggestive of acute appendicitis? a. Rebound tenderness b. Bright red or dark red rectal bleeding c. Abdominal pain that is relieved by eating d. Abdominal pain that is most intense at McBurney point
ANS: D Pain is the cardinal feature. It is initially generalized, usually periumbilical. The pain localizes to the right lower quadrant at McBurney point.

Bright red or dark red rectal bleeding and abdominal pain that is relieved by eating are not signs of acute appendicitis
A chest radiograph film is ordered for a child with suspected cardiac problems. The child's parent asks the nurse, "What will the radiograph show about the heart?" The nurse's response should be based on knowledge that the x-ray film will show: a. bones of chest but not the heart. b. measurement of electrical potential generated from heart muscle. c. permanent record of heart size and configuration. d. computerized image of heart vessels and tissues.
ANS: C A chest radiograph will provide information on the heart size and pulmonary blood-flow patterns. It will provide a baseline for future comparisons. The heart will be visible, as well as the sternum and ribs. Electrocardiography (ECG) measures the electrical potential generated from heart muscle. Echocardiography will produce a computerized image of the heart vessels and tissues by using sound waves.
20. Which statement is most descriptive of Meckel's diverticulum? a.It is more common in females than in males. b.It is acquired during childhood. c.Intestinal bleeding may be mild or profuse. d.Medical interventions are usually sufficient to treat the problem.
ANS: C Blood stools are often a presenting sign of Meckel's diverticulum. It is associated with mild-to-profuse intestinal bleeding. It is twice as common in males as in females, and complications are more frequent in males. Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract and is present in 1% to 4% of the general population. The standard therapy is surgical removal of the diverticulum.

Which is a major complication in a child with chronic renal failure? a. Hypokalemia b. Metabolic alkalosis c. Water and sodium retention d. Excessive excretion of blood urea nitrogen
ANS: C Chronic renal failure leads to water and sodium retention, which contributes to edema and vascular congestion. Hyperkalemia, metabolic acidosis, and retention of blood urea nitrogen are complications of chronic renal failure.
An infant is brought to the emergency department with dehydration. Which physical assessment finding does the nurse expect? a. Weight gain b. Bradycardia c. Poor skin turgor d. Brisk capillary refill
ANS: C Clinical manifestations of dehydration include poor skin turgor, weight loss, lethargy, and tachycardia. The infant would have prolonged capillary refill, not brisk.
Constipation has recently become a problem for a school-age girl. She is healthy except for seasonal allergies that are being treated with antihistamines. The nurse should suspect that the constipation is most likely caused by: a. diet. b. allergies. c. antihistamines. d. emotional factors.
ANS: C Constipation may be associated with drugs such as antihistamines, antacids, diuretics, opioids, antiepileptics, and iron. Because this is the only known change in her habits, the addition of antihistamines is most likely the cause of the diarrhea. With a change in bowel habits, the role of any recently prescribed medications should be assessed.
11. Constipation has recently become a problem for a school-age girl. She is healthy except for seasonal allergies, which are now being successfully treated with antihistamines. The nurse should suspect that the constipation is most likely caused by: a.Diet. b.Allergies. c.Antihistamines. d.Emotional factors.
ANS: C Constipation may be associated with drugs such as antihistamines, antacids, diuretics, opioids, antiepileptics, and iron.

Which should the nurse recommend for the diet of a child with chronic renal failure? a. High in protein b. Low in vitamin D c. Low in phosphorus d. Supplemented with vitamins A, E, and K
ANS: C Dietary phosphorus is controlled by the reduction of protein and milk intake to prevent or control the calcium-phosphorus imbalance. Protein should be limited in chronic renal failure to decrease intake of phosphorus. Vitamin D therapy is administered in chronic renal failure to increase calcium absorption. Supplementation of vitamins A, E, and K is not part of dietary management in chronic renal disease
The nurse is teaching the parent about the diet of a child experiencing severe edema associated with acute glomerulonephritis. Which information should the nurse include in the teaching? a. "You will need to decrease the number of calories in your child's diet." b. "Your child's diet will need an increased amount of protein." c. "You will need to avoid adding salt to your child's food." d. "Your child's diet will consist of low-fat, low-carbohydrate foods."
ANS: C For most children, a regular diet is allowed, but it should contain no added salt. The child should be offered a regular diet with favorite foods. Severe sodium restrictions are not indicated.
Which is a parasite that causes acute diarrhea? a. Shigella organisms b. Salmonella organisms c. Giardia lamblia d. Escherichia coli
ANS: C G. lamblia is a parasite that represents 10% of non-dysenteric illness in the United States. Shigella, Salmonella, and E. coli are bacterial pathogens.
6. A parasite that causes acute diarrhea is: a.Shigella organisms. b.Salmonella organisms. c.Giardia lamblia. d.Escherichia coli.
ANS: C Giardiasis is a parasite that represents 15% of nondysenteric illness in the United States. Shigella, Salmonella, and E. coli are bacterial pathogens.
Which is the most appropriate nursing diagnosis for the child with acute glomerulonephritis? a. Risk for Injury related to malignant process and treatment b. Fluid Volume Deficit related to excessive losses c. Fluid Volume Excess related to decreased plasma filtration d. Fluid Volume Excess related to fluid accumulation in tissues and third spaces
ANS: C Glomerulonephritis has a decreased filtration of plasma, which results in an excessive accumulation of water and sodium that expands plasma and interstitial fluid volumes, leading to circulatory congestion and edema. No malignant process is involved in acute glomerulonephritis. A fluid volume excess is found. The fluid accumulation is secondary to the decreased plasma filtration.
24. Which statement best characterizes hepatitis A? a.The incubation period is 6 weeks to 6 months. b.The principal mode of transmission is through the parenteral route. c.Onset is usually rapid and acute. d.There is a persistent carrier state.

ANS: C Melena is denatured blood from the upper GI tract or bleeding from the right colon. Blood from the perianal or rectal area, hemorrhoids, or lower GI tract would be bright red.
Which action by the school nurse is important in the prevention of rheumatic fever? a. Encourage routine cholesterol screenings. b. Conduct routine blood pressure screenings. c. Refer children with sore throats for throat cultures. d. Recommend salicylates instead of acetaminophen for minor discomforts.
ANS: C Nurses have a role in prevention—primarily in screening school-age children for sore throats caused by group A -hemolytic streptococci. They can achieve this by actively participating in throat culture screening or by referring children with possible streptococcal sore throats for testing. Cholesterol and blood pressure screenings do not facilitate the recognition and treatment of group A -hemolytic streptococci. Salicylates should be avoided routinely because of the risk of Reye syndrome after viral illnesses.
8. Therapeutic management of the child with acute diarrhea and dehydration usually begins with: a.Clear liquids. b.Adsorbents such as kaolin and pectin. c.Oral rehydration solution (ORS). d.Antidiarrheal medications such as paregoric.
ANS: C ORS is the first treatment for acute diarrhea. Clear liquids are not recommended because they contain too much sugar, which may contribute to diarrhea. Adsorbents are not recommended and neither are antidiarrheals because they do not get rid of pathogens.
Which therapeutic management should the nurse prepare to initiate first for a child with acute diarrhea and moderate dehydration? a. Clear liquids b. Adsorbents, such as kaolin and pectin c. Oral rehydration solution (ORS) d. Antidiarrheal medications such as paregoric

14. A 3-year-old child with Hirschsprung's disease is hospitalized for surgery. A temporary colostomy will be necessary. The nurse should recognize that preparing this child psychologically is: a.Not necessary because of child's age. b.Not necessary because the colostomy is temporary. c.Necessary because it will be an adjustment. d.Necessary because the child must deal with a negative body image.
ANS: C The child's age dictates the type and extent of psychologic preparation. When a colostomy is performed, the child who is at least preschool age is told about the procedure and what to expect in concrete terms with the use of visual aids. It is necessary to prepare this age child for procedures. The preschooler is not yet concerned with body image.
Which is best described as the inability of the heart to pump an adequate amount of blood to the systemic circulation at normal filling pressures? a. Pulmonary congestion b. Congenital heart defect c. Heart failure d. Systemic venous congestion
ANS: C The definition of heart failure is the inability of the heart to pump an adequate amount of blood to the systemic circulation at normal filling pressures to meet the body's metabolic demands. Pulmonary congestion is an excessive accumulation of fluid in the lungs. Congenital heart defect is a malformation of the heart present at birth. Systemic venous congestion is an excessive accumulation of fluid in the systemic vasculature.
Which observation made of the exposed abdomen is most indicative of pyloric stenosis? a. Abdominal rigidity b. Substernal retraction c. Palpable olive-like mass d. Marked distention of lower abdomen
ANS: C The diagnosis of pyloric stenosis is often made after the history and physical examination. The olive-like mass is easily palpated when the stomach is empty, the infant is quiet, and the abdominal muscles are relaxed. Abdominal rigidity and substernal retraction are usually not present. The upper abdomen, not lower abdomen, is distended.
17. A histamine-receptor antagonist such as cimetidine (Tagamet) or ranitidine (Zantac) is ordered for an infant with gastroesophageal reflux. The purpose of this is to: a.Prevent reflux. b.Prevent hematemesis. c.Reduce gastric acid production. d.Increase gastric acid production.
ANS: C The mechanism of action of histamine-receptor antagonists is to reduce the amount of acid present in gastric contents and may prevent esophagitis. Preventing reflux and hematemesis, and increasing gastric acid production are not the modes of action of histamine-receptor antagonists.
A histamine-receptor antagonist such as cimetidine (Tagamet) or ranitidine (Zantac) is ordered for an infant with GER. The purpose of this is to: a. prevent reflux. b. prevent hematemesis. c. reduce gastric acid production. d. increase gastric acid production.
ANS: C The mechanism of action of histamine-receptor antagonists is to reduce the amount of acid present in gastric contents and perhaps prevent esophagitis. Preventing reflux or hematemesis and increasing gastric acid production are not the modes of action of histamine-receptor antagonists.
The nurse is admitting a school-age child in acute renal failure with reduced glomerular filtration rate. Which urine test is the most useful clinical indication of glomerular filtration rate? a. pH b. Osmolality c. Creatinine d. Protein level
ANS: C The most useful clinical indication of glomerular filtration is the clearance of creatinine. It is a substance that is freely filtered by the glomerulus and secreted by the renal tubule cells. The pH and osmolality are not estimates of glomerular filtration. Although protein in the urine demonstrates abnormal glomerular permeability, it is not a measure of filtration rate.
The nurse notes that a child has lost 8 pounds after 4 days of hospitalization for acute glomerulonephritis. This is most likely the result of: a. poor appetite. b. increased potassium intake. c. reduction of edema. d. restriction to bed rest.
ANS: C This amount of weight loss in this period is a result of the improvement of renal function and mobilization of edema fluid. Poor appetite and bed rest would not result in a weight loss of 8 pounds in 4 days. Foods with substantial amounts of potassium are avoided until renal function is normalized.

A nurse is receiving report on a newborn admitted yesterday after a gastroschisis repair. In the report, the nurse is told the newborn has a physician's prescription for an NG tube to low intermittent suction. The reporting nurse confirms that the NG tube is to low intermittent suction and draining light green stomach contents. Upon initial assessment, the nurse notes that the newborn has pulled the NG tube out. Which is the priority action the nurse should take? a. Replace the NG tube and continue the low intermittent suction. b. Leave the NG tube out and notify the physician at the end of the shift. c. Leave the NG tube out and monitor for bowel sounds. d. Replace the NG tube, but leave to gravity drainage instead of low wall suction.
ANS: A A newborn with a gastroschisis performed the day before will require bowel decompression with an NG tube to low wall intermittent suction. The nurse's priority action is to replace the NG tube and continue with the low wall intermittent suctioning. The NG tube cannot be left out this soon after surgery. The physician's prescription was to have the NG tube to low wall intermittent suction so the tube cannot be placed to gravity drainage.
1. The nurse is conducting a staff in-service on renal ultrasounds. Which statement describes this diagnostic test? a. Computed tomography uses external radiation to visualize the renal system. b. Visualization of the renal system is accomplished without exposure to radiation or radioactive isotopes. c. Contrast medium and x-rays allow for visualization of the renal system. d. External radiation for x-ray films is used to visualize the renal system, before, during, and after voiding.
ANS: A A renal ultrasound transmits ultrasonic waves through the renal parenchyma allowing for visualization of the renal system without exposure to external beam radiation or radioactive isotopes. Computed tomography uses external radiation and sometimes contrast media to visualize the renal system. An intravenous pyelogram uses contrast medium and external radiation for x-ray films. The voiding cystourethrogram visualizes the renal system with injection of a contrast media into the bladder through the urethral opening and use of x-ray before, during, and after voiding.
A nurse is admitting a child with Crohn disease. Parents ask the nurse, "How is this disease different from ulcerative colitis?" Which statement should the nurse make when answering this question? a. "With Crohn's the inflammatory process involves the whole GI tract." b. "There is no difference between the two diseases." c. "The inflammation with Crohn's is limited to the colon and rectum." d. "Ulcerative colitis is characterized by skip lesions."
ANS: A The chronic inflammatory process of Crohn disease involves any part of the GI tract from the mouth to the anus but most often affects the terminal ileum. Crohn disease involves all layers of the bowel wall in a discontinuous fashion, meaning that between areas of intact mucosa, there are areas of affected mucosa (skip lesions). The inflammation found with ulcerative colitis is limited to the colon and rectum, with the distal colon and rectum the most severely affected. Inflammation affects the mucosa and submucosa and involves continuous segments along the length of the bowel with varying degrees of ulceration, bleeding, and edema.
21. What is characterized by a chronic inflammatory process that may involve any part of the gastrointestinal (GI) tract from mouth to anus? a.Crohn's disease b.Ulcerative colitis c.Meckel's diverticulum d.Irritable bowel syndrome
ANS: A The chronic inflammatory process of Crohn's disease involves any part of the GI tract from the mouth to the anus but most often affects the terminal ileum. Ulcerative colitis, Meckel's diverticulum, and irritable bowel syndrome do not affect the entire GI tract.

ANS: A The drug therapy combination of bismuth subsalicylate, clarithromycin, and metronidazole is effective in the treatment of H. pylori and is prescribed to eradicate it.
The nurse is admitting a child with rheumatic fever. Which therapeutic management should the nurse expect to implement? a. Administering penicillin b. Avoiding salicylates (aspirin) c. Imposing strict bed rest for 4 to 6 weeks d. Administering corticosteroids if chorea develops
ANS: A The goal of medical management is the eradication of the hemolytic streptococci. Penicillin is the drug of choice. Salicylates can be used to control the inflammatory process, especially in the joints, and reduce the fever and discomfort. Bed rest is recommended for the acute febrile stage, but it does not need to be strict. The chorea is transient and will resolve without treatment.
The nurse is admitting a child with a Wilms tumor. Which is the initial assessment finding associated with this tumor? a. Abdominal swelling b. Weight gain c. Hypotension d. Increased urinary output
ANS: A The initial assessment finding with a Wilms (kidney) tumor is abdominal swelling. Weight loss, not weight gain, may be a finding. Hypertension occasionally occurs with a Wilms tumor. Urinary output is not increased, but hematuria may be noted.
The nurse is caring for an infant with a suspected urinary tract infection. Which clinical manifestations should be expected? (Select all that apply.) a. Vomiting b. Jaundice c. Failure to gain weight d. Swelling of the face e. Back pain f. Persistent diaper rash
ANS: A, C, F Vomiting, failure to gain weight, and persistent diaper rash are clinical manifestations observed in an infant with a UTI.
A school-age child is admitted to the hospital with acute glomerulonephritis and oliguria. Which dietary menu items should be allowed for this child? (Select all that apply.) a. Apples b. Bananas c. Cheese d. Carrot sticks e. Strawberries
ANS: A, D, E Moderate sodium restriction and even fluid restriction may be instituted for children with acute glomerulonephritis. Foods with substantial amounts of potassium are generally restricted during the period of oliguria. Apples, carrot sticks, and strawberries would be items low in sodium and allowed. Bananas are high in potassium and cheese is high in sodium. Those items would be restricted.
A nurse is planning preoperative care for a newborn with tracheoesophageal fistula (TEF). Which interventions should the nurse plan to implement? (Select all that apply.) a. Positioning with head elevated on a 30-degree plane b. Feedings through a gastrostomy tube c. Nasogastric tube to continuous low wall suction d. Suctioning with a Replogle tube passed orally to the end of the pouch e. Gastrostomy tube to gravity drainage
ANS: A, D, E The most desirable position for a newborn who has TEF is supine (or sometimes prone) with the head elevated on an inclined plane of at least 30 degrees. This positioning minimizes the reflux of gastric secretions at the distal esophagus into the trachea and bronchi, especially when intraabdominal pressure is elevated. It is imperative to immediately remove any secretions that can be aspirated. Until surgery, the blind pouch is kept empty by intermittent or continuous suction through an indwelling double-lumen or Replogle catheter passed orally or nasally to the end of the pouch. In some cases, a percutaneous gastrostomy tube is inserted and left open so that any air entering the stomach through the fistula can escape, thus minimizing the danger of gastric contents being regurgitated into the trachea. The gastrostomy tube is emptied by gravity drainage. Feedings through the gastrostomy tube and irrigations with fluid are contraindicated before surgery in an infant with a distal TEF. A nasogastric tube to low intermittent suctioning could not be accomplished because the esophagus ends in a blind pouch in TEF.
Which is included in the diet of a child with minimal change nephrotic syndrome? a. High protein b. Salt restriction c. Low fat d. High carbohydrate
ANS: B Salt is usually restricted (but not eliminated) during the edema phase. The child has little appetite during the acute phase. Favorite foods are provided (with the exception of high-salt ones) in an attempt to provide nutritionally complete meals.
Parents of a child undergoing an endoscopy to rule out peptic ulcer disease (PUD) from H. pylori ask the nurse, "If H. pylori is found will my child need another endoscopy to know that it is gone?" Which is the nurse's best response? a. "Yes, the only way to know the H. pylori has been eradicated is with another endoscopy." b. "We can collect a stool sample and confirm that the H. pylori has been eradicated." c. "A blood test can be done to determine that the H. pylori is no longer present." d. "Your child will always test positive for H. pylori because after treatment it goes into remission, but can't be completely eradicated."
ANS: B An upper endoscopy is the procedure initially performed to diagnose PUD. A biopsy can determine the presence of H. pylori. Polyclonal and monoclonal stool antigen tests are an accurate, noninvasive method to confirm H. pylori has been eradicated after treatment. A blood test can identify the presence of the antigen to this organism, but because H. pylori was already present it would not be as accurate as a stool sample to determine whether it has been eradicated. H. pylori can be treated and, once the treatment is complete, the stool sample can determine that it was eradicated.
35. An infant with short bowel syndrome will be discharged home on total parenteral nutrition (TPN) and gastrostomy feedings. Nursing care should include: a. Preparing the family for impending death. b. Teaching the family signs of central venous catheter infection. c. Teaching the family how to calculate caloric needs. d. Securing TPN and gastrostomy tubing under diaper to lessen risk of dislodgment.
ANS: B During TPN therapy care must be taken to minimize the risk of complications related to the central venous access device such as catheter infections, occlusions, or accidental removal. This is an important part of family teaching. The prognosis for patients with short bowel syndrome depends in part on the length of residual small intestine. It has improved with advances in TPN. Although parents need to be taught about nutritional needs, the caloric needs and prescribed TPN and rate are the responsibility of the health care team. The tubes should not be placed under the diapers because of risk of infection.
27. A newborn was admitted to the nursery with a complete bilateral cleft lip and palate. The physician explained the plan of therapy and its expected good results. However, the mother refuses to see or hold her baby. Initial therapeutic approach to the mother should be to: a. Restate what the physician has told her about plastic surgery. b. Encourage her to express her feelings. c. Emphasize the normalcy of her baby and the baby's need for mothering. d. Recognize that negative feelings toward the child continue throughout childhood.
ANS: B For parents cleft lip and cleft palate deformities are particularly disturbing. The nurse must place emphasis not only on the infant's physical needs but also on the parents' emotional needs. The mother needs to be able to express her feelings before the acceptance of her child can occur. Although discussing plastic surgery will be addressed, it is not part of the initial therapeutic approach. As the mother expresses her feelings, the nurse's actions should convey to the parents that the infant is a precious human being. The child's normalcy is emphasized, and the mother is assisted to recognize the child's uniqueness. A focus on abnormal maternal-infant attachment would be inappropriate at this time.

Calcium carbonate is given with meals to a child with chronic renal disease. The purpose of this is to: a. prevent vomiting. b. bind phosphorus. c. stimulate appetite. d. increase absorption of fat-soluble vitamins.
ANS: B Oral calcium carbonate preparations combine with phosphorus to decrease gastrointestinal absorption and the serum levels of phosphate. Serum calcium levels are increased by the calcium carbonate, and vitamin D administration is necessary to increase calcium absorption. Calcium carbonate does not prevent vomiting, stimulate appetite, or increase the absorption of fat-soluble vitamins.
A school-age child has been admitted to the hospital with an exacerbation of nephrotic syndrome. Which clinical manifestations should the nurse expect to assess? (Select all that apply.) a. Weight loss b. Facial edema c. Cloudy smoky brown-colored urine d. Fatigue e. Frothy-appearing urine
ANS: B, D, E A child with nephrotic syndrome will present with facial edema, fatigue, and frothy-appearing urine (proteinuria). Weight gain, not loss, is expected because of the fluid retention. Cloudy smoky brown-colored urine is seen with acute glomerulonephritis but not with nephrotic syndrome because there is no gross hematuria associated with nephrotic syndrome.
The nurse is preparing to care for an infant returning from pyloromyotomy surgery. Which prescribed orders should the nurse anticipate implementing? (Select all that apply.) a. NPO for 24 hours b. Administration of analgesics for pain c. Ice bag to the incisional area d. IV fluids continued until tolerating PO e. Clear liquids as the first feeding
ANS: B, D, E Feedings are usually instituted soon after a pyloromyotomy surgery, beginning with clear liquids advancing to formula or breast milk as tolerated. IV fluids are administered until the infant is taking and retaining adequate amounts by mouth. Appropriate analgesics should be given around the clock because pain is continuous. Ice should not be applied to the incisional area as it vasoconstricts and would reduce circulation to the incisional area and impair healing.
9. A school-age child with diarrhea has been rehydrated. The nurse is discussing the child's diet with the family. Which statement by the parent would indicate a correct understanding of the teaching? a."I will keep my child on a clear liquid diet for the next 24 hours." b."I should encourage my child to drink carbonated drinks but avoid food for the next 24 hours." c."I will offer my child bananas, rice, applesauce, and toast for the next 48 hours." d."I should have my child eat a normal diet with easily digested foods for the next 48 hours."
ANS: D Easily digested foods such as cereals, cooked vegetables, and meats should be provided for the child. Early reintroduction of nutrients is desirable. Continued feeding or reintroduction of a regular diet has no adverse effects and actually lessens the severity and duration of the illness. Clear liquids and carbonated drinks have high carbohydrate content and few electrolytes. Caffeinated beverages should be avoided because caffeine is a mild diuretic. A diet of bananas, applesauce, and toast is contraindicated because it has little nutritional value (low in energy and protein), is high in carbohydrates, and is low in electrolytes.

Continued feeding or reintroduction of a regular diet has no adverse effects and actually lessens the severity and duration of the illness. Clear liquids and carbonated drinks have high carbohydrate content and few electrolytes. Caffeinated beverages should be avoided because caffeine is a mild diuretic. The BRAT diet has little nutritional value and is high in carbohydrates.
The nurse is caring for a child with acute renal failure. Which clinical manifestation should the nurse recognize as a sign of hyperkalemia? a. Dyspnea b. Seizure c. Oliguria d. Cardiac arrhythmia
ANS: D Hyperkalemia is the most common threat to the life of the child. Signs of hyperkalemia include electrocardiograph anomalies such as prolonged QRS complex, depressed ST segments, peaked T waves, bradycardia, or heart block. Dyspnea, seizure, and oliguria are not manifestations of hyperkalemia.
2. Which type of dehydration results from water loss in excess of electrolyte loss? a.Isotonic dehydration b.Isosmotic dehydration c.Hypotonic dehydration d.Hypertonic dehydration
ANS: D Hypertonic dehydration results from water loss in excess of electrolyte loss. This is the most dangerous type of dehydration. It is caused by feeding children fluids with high amounts of solute. Isotonic dehydration occurs in conditions in which electrolyte and water deficits are present in balanced proportion. Isosmotic dehydration is another term for isotonic dehydration. Hypotonic dehydration occurs when the electrolyte deficit exceeds the water deficit, leaving the serum hypotonic.
osé is a 4-year-old child scheduled for a cardiac catheterization. Preoperative teaching should be: a. directed at his parents because he is too young to understand. b. detailed in regard to the actual procedures so he will know what to expect. c. done several days before the procedure so that he will be prepared. d. adapted to his level of development so that he can understand.
ANS: D Preoperative teaching should always be directed at the child's stage of development. The caregivers also benefit from the same explanations. The parents may ask additional questions, which should be answered, but the child needs to receive the information based on developmental level. Preschoolers will not understand in-depth descriptions and should be prepared close to the time of the cardiac catheterization.
Which explanation regarding cardiac catheterization is appropriate for a preschool child? a. Postural drainage will be performed every 4 to 6 hours after the test. b. It is necessary to be completely "asleep" during the test. c. The test is short, usually taking less than 1 hour. d. When the procedure is done, you will have to keep your leg straight for at least 4 hours.
ANS: D The child's leg will have to be maintained in a straight position for approximately 4 hours. Younger children can be held in the parent's lap with the leg maintained in the correct position. Postural drainage will not be performed unless the child has corresponding pulmonary problems. The child should be sedated to lie still, but being completely asleep is not necessary. The test will vary in length of time from start to finish.
Surgical closure of the ductus arteriosus would: a. stop the loss of unoxygenated blood to the systemic circulation. b. decrease the edema in legs and feet. c. increase the oxygenation of blood. d. prevent the return of oxygenated blood to the lungs.
ANS: D The ductus arteriosus allows blood to flow from the higher-pressure aorta to the lower-pressure pulmonary artery, causing a right-to-left shunt. If this is surgically closed, no additional oxygenated blood (from the aorta) will return to the lungs through the pulmonary artery. The aorta carries oxygenated blood to the systemic circulation. Because of the higher pressure in the aorta, blood is shunted into the pulmonary artery and the pulmonary circulation. Edema in the legs and feet is usually a sign of heart failure. This repair would not directly affect the edema. Increasing the oxygenation of blood would not interfere with the return of oxygenated blood to the lungs.
Which is the most common cause of acute renal failure in children? a. Pyelonephritis b. Tubular destruction c. Urinary tract obstruction d. Severe dehydration
ANS: D The most common cause of acute renal failure in children is dehydration or other causes of poor perfusion that may respond to restoration of fluid volume. Pyelonephritis and tubular destruction are not common causes of acute renal failure. Obstructive uropathy may cause acute renal failure, but it is not the most common cause.
