Chapter 18: Respiratory Disorders Questions

11. An 18-month-old child is seen in the clinic with AOM. Trimethoprim- sulfamethoxazole (Bactrim) is prescribed. Which statement made by the parent indicates a correct understanding of the instructions? a. I should administer all the prescribed medication. b. I should continue medication until the symptoms subside. c. I will immediately stop giving medication if I notice a change in hearing. d. I will stop giving medication if fever is still present in 24 hours.

ANS: A Antibiotics should be given for their full course to prevent recurrence of infection with resistant bacteria. Symptoms may subside before the full course is given. Hearing loss is a complication of AOM. Antibiotics should continue to be given. Medication may take 24 to 48 hours to make symptoms subside. It should be continued.

24. A child is admitted to the hospital with asthma. Which assessment findings support this diagnosis? a. Nonproductive cough, wheezing b. Fever, general malaise c. Productive cough, rales d. Stridor, substernal retractions

ANS: A Asthma presents with a nonproductive cough and wheezing. Pneumonia appears with an acute onset, fever, and general malaise. A productive cough and rales would be indicative of pneumonia. Stridor and substernal retractions are indicative of croup.

16. A school-age child had an upper respiratory tract infection for several days and then began having a persistent dry, hacking cough that was worse at night. The cough has become productive in the past 24 hours. This is most suggestive of which diagnosis? a. Bronchitis b. Bronchiolitis c. Viral-induced asthma d. Acute spasmodic laryngitis

ANS: A Bronchitis is characterized by these symptoms and occurs in children older than 6 years. Bronchiolitis is rare in children older than 2 years. Asthma is a chronic inflammation of the airways that may be exacerbated by a virus. Acute spasmodic laryngitis occurs in children between 3 months and 3 years.

29. Parents of a child with cystic fibrosis ask the nurse about genetic implications of the disorder. Which statement, made by the nurse, expresses accurately the genetic implications? a. If it is present in a child, both parents are carriers of this defective gene. b. It is inherited as an autosomal dominant trait. c. It is a genetic defect found primarily in non-Caucasian population groups. d. There is a 50% chance that siblings of an affected child also will be affected.

ANS: A CF is an autosomal recessive gene inherited from both parents and is inherited as an autosomal recessive, not autosomal dominant, trait. CF is found primarily in Caucasian populations. An autosomal recessive inheritance pattern means that there is a 25% chance a sibling will be infected but a 50% chance a sibling will be a carrier.

30. A nurse is teaching nursing students about clinical manifestations of cystic fibrosis (CF). Which is/are the earliest recognizable clinical manifestation(s) of CF? a. Meconium ileus b. History of poor intestinal absorption c. Foul-smelling, frothy, greasy stools d. Recurrent pneumonia and lung infections

ANS: A The earliest clinical manifestation of CF is a meconium ileus, which is found in about 10% of children with CF. Clinical manifestations include abdominal distention, vomiting, failure to pass stools, and rapid development of dehydration. History of malabsorption is a later sign that manifests as failure to thrive. Foul-smelling stools are a later manifestation of CF. Recurrent respiratory tract infections are a later sign of CF.

4. Decongestant nose drops are recommended for a 10-month-old infant with an upper respiratory tract infection. Instructions for nose drops should include which action? a. Avoid using for more than 3 days. b. Keep drops to use again for nasal congestion. c. Administer drops until nasal congestion subsides. d. Administer drops after feedings and at bedtime.

ANS: A Vasoconstrictive nose drops such as phenylephrine (Neo-Synephrine) should not be used for more than 3 days to avoid rebound congestion. Drops should be discarded after one illness because they may become contaminated with bacteria. Vasoconstrictive nose drops can have a rebound effect after 3 days of use. Drops administered before feedings are more helpful.

1. The nurse is teaching nursing students about normal physiologic changes in the respiratory system of toddlers. Which best describes why toddlers have fewer respiratory tract infections as they grow older? a. The amount of lymphoid tissue decreases. b. Repeated exposure to organisms causes increased immunity. c. Viral organisms are less prevalent in the population. d. Secondary infections rarely occur after viral illnesses.

ANS: B Children have increased immunity after exposure to a virus. The amount of lymphoid tissue increases as children grow older. Viral organisms are not less prevalent, but older children have the ability to resist invading organisms. Secondary infections after viral illnesses include Mycoplasma pneumoniae and group A b-hemolytic streptococcal infections.

14. Which type of croup is always considered a medical emergency? a. Laryngitis b. Epiglottitis c. Spasmodic croup d. Laryngotracheobronchitis (LTB)

ANS: B Epiglottitis is always a medical emergency needing antibiotics and airway support for treatment. Laryngitis is a common viral illness in older children and adolescents, with hoarseness and URI symptoms. Spasmodic croup is treated with humidity. LTB may progress to a medical emergency in some children.

13. The nurse is assessing a child with acute epiglottitis. Examining the childs throat by using a tongue depressor might precipitate which symptom or condition?a. Inspiratory stridor b. Complete obstruction c. Sore throat d. Respiratory tract infection

ANS: B If a child has acute epiglottitis, examination of the throat may cause complete obstruction and should be performed only when immediate intubation can take place. Stridor is aggravated when a child with epiglottitis is supine. Sore throat and pain on swallowing are early signs of epiglottitis. Epiglottitis is caused by H. influenzae in the respiratory tract.

15. The nurse encourages the mother of a toddler with acute laryngotracheobronchitis (LTB) to stay at the bedside as much as possible. The nurses rationale for this action is described primarily in which statement? a. Mothers of hospitalized toddlers often experience guilt. b. The mothers presence will reduce anxiety and ease childs respiratory efforts. c. Separation from mother is a major developmental threat at this age. d. The mother can provide constant observations of the childs respiratory efforts.

ANS: B The familys presence will decrease the childs distress. It is true that mothers of hospitalized toddlers often experience guilt but this is not the best answer. The main reason to keep parents at the childs bedside is to ease anxiety and therefore respiratory effort. The child should have constant monitoring by cardiorespiratory monitor and noninvasive oxygen saturation monitoring, but the parent should not play this role in the hospital.

22. A nurse is admitting an infant with asthma. The nurse understands that asthma in infants is usually triggered by: a. medications. b. a viral infection. c. exposure to cold air. d. allergy to dust or dust mites.

ANS: B Viral illnesses cause inflammation that causes increased airway reactivity in asthma. Medications such as aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), and antibiotics may aggravate asthma, but not frequently in infants. Exposure to cold air may exacerbate already existing asthma. Allergy is associated with asthma, but 20% to 40% of children with asthma have no evidence of allergic disease.

26. b-Adrenergic agonists and methylxanthines are often prescribed for a child with an asthma attack. Which describes their action? a. Liquefy secretions. b. Dilate the bronchioles. c. Reduce inflammation of the lungs. d. Reduce infection.

ANS: B b-Adrenergic agonists and methylxanthines work to dilate the bronchioles in acute exacerbations. These medications do not liquefy secretions or reduce infection. Corticosteroids and mast cell stabilizers reduce inflammation in the lungs.

25. It is now recommended that children with asthma who are taking long-term inhaled steroids should be assessed frequently because which disease or assessment findings may develop? a. Cough b. Osteoporosis c. Slowed growth d. Cushing syndrome

ANS: C The growth of children on long-term inhaled steroids should be assessed frequently to assess for systemic effects of these drugs. Cough is prevented by inhaled steroids. No evidence exists that inhaled steroids cause osteoporosis. Cushing syndrome is caused by long-term systemic steroids.

17. Which frequency is recommended for childhood skin testing for tuberculosis (TB) using the Mantoux test? a. Every year for all children older than 2 years b. Every year for all children older than 10 years c. Every 2 years for all children starting at age 1 year d. Periodically for children who reside in high-prevalence regions

ANS: D Children who reside in high-prevalence regions for TB should be tested every 2 to 3 years. Annual testing is not necessary. Testing is not necessary unless exposure is likely or an underlying medical risk factor is present.

6. The parent of an infant with nasopharyngitis should be instructed to notify the health professional if the infant displays which clinical manifestation? a. Fussiness b. Coughing c. A fever over 99 F d. Signs of an earache

ANS: D If an infant with nasopharyngitis shows signs of an earache, it may mean a secondary bacterial infection is present and the infant should be referred to a practitioner for evaluation. Irritability is common in an infant with a viral illness. Cough can be a sign of nasopharyngitis. Fever is common in viral illnesses.

9. Chronic otitis media with effusion (OME) is differentiated from acute otitis media (AOM) because it is usually characterized by: a. a fever as high as 40 C (104 F). b. severe pain in the ear. c. nausea and vomiting. d. a feeling of fullness in the ear.

ANS: D OME is characterized by feeling of fullness in the ear or other nonspecific complaints. Fever is a sign of AOM. OME does not cause severe pain. This may be a sign of AOM. Nausea and vomiting are associated with otitis media.

10. Parents have understood teaching about prevention of childhood otitis media if they make which statement? a. We will only prop the bottle during the daytime feedings. b. Breastfeeding will be discontinued after 4 months of age. c. We will place the child flat right after feedings. d. We will be sure to keep immunizations up to date.

ANS: D Parents have understood the teaching about preventing childhood otitis media if they respond they will keep childhood immunizations up to date. The child should be maintained upright during feedings and after. Otitis media can be prevented by exclusively breastfeeding until at least 6 months of age. Propping bottles is discouraged to avoid pooling of milk while the child is in the supine position.

5. Which is an appropriate nursing intervention when caring for an infant with an upper respiratory tract infection and elevated temperature? a. Give tepid water baths to reduce fever. b. Encourage food intake to maintain caloric needs. c. Have child wear heavy clothing to prevent chilling. d. Give small amounts of favorite fluids frequently to prevent dehydration.

ANS: D Preventing dehydration by small frequent feedings is an important intervention in the febrile child. Tepid water baths may induce shivering, which raises temperature. Food should not be forced; it may result in the child vomiting. The febrile child should be dressed in light, loose clothing.

28. Which drug is usually given first in the emergency treatment of an acute, severe asthma episode in a young child? a. Ephedrine b. Theophylline c. Aminophylline d. Short-acting b2 agonists

ANS: D Short-acting b2 agonists are the first treatment in an acute asthma exacerbation. Ephedrine is not helpful in acute asthma exacerbations. Theophylline is unnecessary for treating asthma exacerbations. Aminophylline is not helpful for acute asthma exacerbation.

19. The mother of a toddler yells to the nurse, Help! He is choking to death on his food. The nurse determines that lifesaving measures are necessary based on which symptom? a. Gagging b. Coughing c. Pulse over 100 beats/min d. Inability to speak

ANS: D The inability to speak is indicative of a foreign-body airway obstruction of the larynx. Abdominal thrusts are needed for treatment of the choking child. Gagging indicates irritation at the back of the throat, not obstruction. Coughing does not indicate a complete airway obstruction. Tachycardia may be present for many reasons.

3. Which explains why cool-mist vaporizers rather than steam vaporizers are recommended in home treatment of childhood respiratory tract infections? a. They are safer. b. They are less expensive. c. Respiratory secretions are dried. d. A more comfortable environment is produced.

ANS: A Cool-mist vaporizers are safer than steam vaporizers, and little evidence exists to show any advantages to steam. The cost of cool-mist and steam vaporizers is comparable. Steam loosens secretions, not dries them. Both may promote a more comfortable environment, but cool-mist vaporizers present decreased risk for burns and growth of organisms.

2. A nurse is charting that a hospitalized child has labored breathing. Which describes labored breathing? a. Dyspnea b. Tachypnea c. Hypopnea d. Orthopnea

ANS: A Dyspnea is labored breathing. Tachypnea is rapid breathing. Hypopnea is breathing that is too shallow. Orthopnea is difficulty breathing except in upright position.

12. An infants parents ask the nurse about preventing OM. Which should be recommended? a. Avoid tobacco smoke. b. Use nasal decongestant. c. Avoid children with OM. d. Bottle-feed or breastfeed in supine position.

ANS: A Eliminating tobacco smoke from the childs environment is essential for preventing OM and other common childhood illnesses. Nasal decongestants are not useful in preventing OM. Children with uncomplicated OM are not contagious unless they show other upper respiratory tract infection (URI) symptoms. Children should be fed in an upright position to prevent OM.

23. A nurse is conducting an in-service on asthma. Which statement is the most descriptive of bronchial asthma? a. There is heightened airway reactivity. b. There is decreased resistance in the airway. c. The single cause of asthma is an allergic hypersensitivity. d. It is inherited.

ANS: A In bronchial asthma, spasm of the smooth muscle of the bronchi and bronchioles causes constriction, producing impaired respiratory function. In bronchial asthma, there is increased resistance in the airway. There are multiple causes of asthma, including allergens, irritants, exercise, cold air, infections, medications, medical conditions, and endocrine factors. Atopy or development of an immunoglobulin E (IgE)mediated response is inherited but is not the only cause of asthma.

27. Parents of two school-age children with asthma ask the nurse, What sports can our children participate in? The nurse should recommend which sport? a. Soccer b. Running c. Swimming d. Basketball

ANS: C Swimming is well tolerated in children with asthma because they are breathing air fully saturated with moisture and because of the type of breathing required in swimming. Exercise-induced bronchospasm is more common in sports that involve endurance, such as soccer. Prophylaxis with medications may be necessary.

7. It is generally recommended that a child with acute streptococcal pharyngitis can return to school: a. when sore throat is better. b. if no complications develop. c. after taking antibiotics for 24 hours. d. after taking antibiotics for 3 days.

ANS: C After children have taken antibiotics for 24 hours, they are no longer contagious to other children. Sore throat may persist longer than 24 hours after beginning antibiotic therapy, but the child is no longer considered contagious. Complications may take days to weeks

8. A child is diagnosed with influenza, probably type A disease. Management includes which recommendation? a. Clear liquid diet for hydration b. Aspirin to control fever c. Amantadine hydrochloride (Symmetrel) to reduce symptoms d. Antibiotics to prevent bacterial infection

ANS: C Amantadine hydrochloride may reduce symptoms related to influenza A if administered within 24 to 48 hours of onset. It is ineffective against type B or C. A clear liquid diet is not necessary for influenza, but maintaining hydration is important. Aspirin is not recommended in children because of increased risk of Reye syndrome. Acetaminophen or ibuprofen is a better choice. Preventive antibiotics are not indicated for influenza unless there is evidence of a secondary bacterial infection.
