Pediatrics #2: Airway & Breathing

Question 1

Tonsils (4)

Answer 1

Masses of lymph tissue in the pharyngeal area

Filter pathogenic organisms, help protect respiratory and GI tract

Contribute to antibody formation

Highly vascular, help to protect against infection and harmful organisms entering through the mouth

Question 2

Tonsillitis (4)

Answer 2

Inflammation of palatine and/or pharyngeal (adenoids) tonsils

Palatine tonsils are those removed during tonsillectomy

Pharyngeal (adenoids) are located above palatine tonsils on the posterior wall of the nasopharynx

Removal of the pharyngeal tonsils is called an adenoidectomy

Question 3

Tonsillitis occurs in ….. (2)

Answer 3

Occurs often in children, rarely in those younger than 2 years of age

Most common in 3-7 year old

Question 4

Tonsillitis common S/S (8)

Answer 4

Fever
Sore throat
Foul-smelling breath d/t infection
Dysphagia
Odynophagia (painful swallowing)
Tender cervical lymph nodes
Lethargy
Malaise

Question 5

Treatment (6)

Answer 5

Antibiotics (if d/t bacterial infection)
Liquid acetaminophen (remember: NO aspirin for kids)
Fluid replacement
Rest
Warm saltwater gargles
Surgery (if recurrent or chronic)

Question 6

Differential: Peritonsillar abscess (if infection spreads behind tonsils) (2)

Answer 6

Severe sore throat, fever, drooling (don’t want to swallow), foul-smelling breath, trismus (lockjaw), muffled voice quality

Tx: drainage of the abscess, antibiotics, hydration, pain management

Question 7

Tonsillectomy: Pre-op (4)

Answer 7

Medications: No ibuprofen-type medications, herbal supplements (ginkgo, Echinacea) for 2 weeks prior to surgery

Diet - NPO after midnight the day before the procedure

Psychological support

Talk to the child in words that are age-appropriate
Offer a tour of hospital if possible

Question 8

Tonsillectomy: Post-op 1/2 (4)

Answer 8

Psychological support: regression to cope with surgery

Monitor for frequent swallowing or throat clearing (could indicate bleeding at operative site)

Snoring or breathing trouble may still be present post-op d/t swelling in the throat - subside after swelling does 7 days after surgery

Hydration: water, diluted juice, electrolyte solutions (triple normal fluid intake) (no substances that coat the throat such as milk - can cause cough which causes bleeding)

Question 9

Tonsillectomy: Post-op 2/2 (5)

Answer 9

Discourage from coughing or blowing nose
Diet: avoid acidic foods (irritating)
Recovery time: 7-10 days (on average)
Activity: return to school when off narcotics, no physical activity/sports for 10 days
Pain medications: acetaminophen, ibuprofen, hydromorphone if warranted

Question 10

Epiglottitis: Etiology (5)

Answer 10

Bacterial infection
Most common bacteria is Haemophlius influenzae type b (Hib)
Infection causes inflammation and swelling of the epiglottis - supraglottic (laryngitis is subglottic)
Affects breathings by obstructing passage of air to lungs (can turn emergent very quickly)
Commonly affects children between 2-8 years of age

Question 11

Epiglottitis S/S (8)

Answer 11

Symptoms appear suddenly

Fever and sore throat are usually first symptoms

Dysphagia, muffled voice

Drooling of saliva

Distinctive, large, cherry red edematous epiglottis

Child will likely insist on sitting upright (like tripod)

Restless, frightened, and apprehensive

Possible suprasternal and substernal retractions

Question 12

Epiglottitis Interventions (4)

Answer 12

NO STRESS! Keep client calm until the airway is stabilized
Allow the child to remain in a position of comfort with a caregiver
Nurse should not attempt epiglottis visualization with tongue depressor, nor should the nurse obtain a throat culture
Maintain droplet precautions until client has received effective antibiotic therapy for 24 hours

Question 13

Bronchiolitis: Etiology (3)

Answer 13

A lower respiratory tract infection - bronchiolar level (most commonly caused by viral infection, RSV)

Symptoms generally worsen for the first 3-5 days and then gradually improve

Leading cause of hospitalization in infants and young children (mainly affects infants due to immature immune system and lack of developed cilia)

Question 14

Bronchiolitis: Patho & gen info (4)

Answer 14

Edema and secretions of the lower respiratory tract cause lower airway obstruction with extensive mucus plugging that could lead to atelectasis

Produces small airway obstruction/air trapping

In >90% of cases, pathogen is respiratory syncytial virus (RSV) (Remember: RSV is contact precautions)

Nasal swab will confirm diagnosis

Question 15

Breath sounds are variable (fine inspiratory crackles, high pitched prolonged expiratory wheezes)

Fever over 100.4 degrees F (38 degrees C)

Question 17

Bronchiolitis: S/S 2/2 (4)

Answer 17

Rhinorrhea (runny nose)

Irritating cough/sneezing

1 to 3 days after onset: Increasing tachypnea and respiratory distress

Increased work of breathing (wheezing with prolonged expiratory phase) (in worse cases, pt may have retractions, nasal flaring, cyanosis, longer episodes of apnea, respirations over 60-80 → all require immediate attention)

Question 18

Bronchiolitis: Interventions (5)

Answer 18

Maintain hydration → IV fluids

Control fever (antipyretics)

Close, frequent assessment to monitor for deterioration
Arterial blood gasses, if necessary

Question 19

Pneumonia: Etiology & patho (7)

Answer 19

Pneumonia is a lower respiratory tract infection
Inflammation of the lung parenchyma (tissue of the lung that does gas exchange)
Extravasation of fluid to alveoli, causing hypoxia
Caused by a virus, bacteria, chemical irritant, fungi, or parasite
Air sacs fill with exudate
Pneumonia occurs more often in boys than girls
Viral pneumonia occurs more frequently than bacterial pneumonia, but bacterial pneumonia is more serious

Question 20

Pneumonia: S/S (8)

Answer 20

Adequate hydration
Family support

Question 22

Asthma (3)

Answer 22

Chronic inflammatory disorder that is characterized by:
Airway obstruction due to inflammation (triggered by exposure to substances causing an allergic reaction)

Bronchial hyperresponsiveness - bronchospasm

(Swelling and inflammation of the airway, tightening of the muscles = difficulty breathing)

Question 23

Asthma S/S (6)

Answer 23

Dyspnea
Wheezing
Coughing

Question 26

Peak flow meter: shows maximum volume that can be exhaled in 1 second (L/min). What does green, yellow, and red mean?

Answer 26

Green = > 79% of personal best (airway is ok) Yellow = 50-79% of personal best (rescue inhaler should be used - suggests exacerbation) Red = <50% of personal best (emergency - suggests narrowing of airway)

Question 27

Bronchopulmonary Dysplasia (BPD) (Chronic lung disease) (3)

Answer 27

Chronic lung disease associated with respiratory distress syndrome (long-term respiratory problems) Usually associated with prematurity (premature infants) Caused by damage to the lungs from mechanical ventilation and prolonged oxygen treatment that causes scarring in the lung tissue

Question 30

BPD S/S (8)

Answer 30

Tachypnea Increased work of breathing Chest retractions Nasal flaring Grunting Decreased breath sounds, crackles, occasionally expiratory wheezing Respiratory acidosis on arterial blood gas Tachycardia

Question 31

BPD diagnosis (1)

Answer 31

Diagnosis is made when mechanical ventilator and/or oxygen is still necessary after a premature infant has reached the equivalent of 36 weeks gestation

Question 32

BPD TX (2)

Answer 32

No specific tx exists for BPD except to maintain adequate arterial blood gasses with the administration of oxygen and to avoid progression of disease Adequate (not over increase!) hydration is extremely important because they lose a lot of fluid thru lungs - however, they’re very susceptible to interstitial edema → Monitor both fluid volume deficit and excess

Question 33

BPD Interventions 1/2 (4)

Answer 33

Bronchodilators, steroids (maximize airway clearance), diuretics (diminish excess fluid in lungs) Oxygen therapy Mechanical ventilation until the lungs mature (several months may be required in most severe cases) (usually weened off by age of 1 year) Nutrition through nasogastric tube or orally when tolerated

Answer 34

Support from family and friends Regular check-ups and vaccinations No smoking in home Avoid other lung irritants

Question 35

Cystic Fibrosis (3)

Answer 35

Inherited, genetic disease of the exocrine (mucus-producing) glands (mutation in the gene that regulates sweat, digestive enzymes, and mucus) Thick mucus secretions in pancreas and lungs (excessive sodium absorption in the lungs, turning usually thin secretions into thick. Similarly in GI and reproductive systems) (in pancreas, ducts are plugged, so enzymes to break down fats, proteins, carbs are not made, and these nutrients are not digested) Electrolyte abnormalities in sweat gland secretions

Question 36

Cystic fibrosis diagnosis

Answer 36

A sweat chloride test of greater than 60 mEq/L demonstrates a positive value for a diagnosis of CF (salty perspiration)

Question 52

Nonorganic failure to thrive (1)

Answer 52

Examples of non-organic FTT include lack of food intake due to an inability to afford an appropriate formula, problems with feeding techniques, improperly prepared formula (over-diluting the formula), or an inadequate supply of breast milk (due to the mother being exhausted, under stress or in a poor nutritional state).

Question 53

Aspirin for a child (3)

Answer 53

Reyes syndrome Better to never give a kid aspirin Reye's syndrome, also known as Reye syndrome, is a rare but serious condition that causes swelling in the liver and brain. Reye's syndrome can occur at any age but usually affects children and teenagers after a viral infection, most commonly the flu or chickenpox.
