Question

A nurse is caring for a school-age child who has cystic fibrosis.

Answer 1

Correct Answers:

Dornase alfa
Acetaminophen
Water-soluble vitamins
Pancreatic lipase

Rationale :

🧬 Dornase alfa (Pulmozyme):

💠 This is a recombinant human deoxyribonuclease I enzyme that cleaves extracellular DNA in the mucus of clients with cystic fibrosis (CF).

💠This DNA is released by degenerating neutrophils and contributes to the viscosity of mucus.

💠 By reducing this thickness, Dornase alfa improves airway clearance, reduces infection risk, and helps maintain pulmonary function.

🧬 Acetaminophen:

💠As an antipyretic and mild analgesic, acetaminophen is appropriate for managing fever and mild pain in pediatric clients.

💠 Children with CF are prone to recurrent infections and may present with elevated body temperature, making acetaminophen a safe and effective choice due to its minimal gastrointestinal effects.

🧬 Water-soluble vitamins (A, D, E, K):

💠These fat-soluble vitamins must be given in water-miscible forms in clients with CF due to their pancreatic insufficiency, which leads to malabsorption of fats.

💠 Deficiencies in these vitamins can result in impaired vision (Vit A), bone health issues (Vit D), coagulopathy (Vit K), and immune dysfunction (Vit E).

🧬 Pancreatic lipase (Pancrelipase):

💠A digestive enzyme replacement vital in CF, as these clients produce insufficient enzymes due to pancreatic duct blockage from thick mucus.

💠Supplementation aids in nutrient absorption, especially fats and proteins, thus preventing failure to thrive and steatorrhea (foul-smelling, greasy stools).

Answer 2

Correct Answers

Irritability [ Acute Laryngotracheobronchitis ; Pneumonia ]
Cough findings at 0800 [ Acute Laryngotracheobronchitis ]
Stridor [ Acute Laryngotracheobronchitis ]
Temperature [ Acute Laryngotracheobronchitis ; Pneumonia ]

Rationale :

Irritability → Both

🦚 Irritability in pediatric clients is a non-specific sign but often the earliest clue of respiratory distress or systemic illness.

🦚 In acute laryngotracheobronchitis, irritability may occur from upper airway narrowing, which causes dyspnea, anxiety, and restlessness.

🦚 In pneumonia, it may be due to fever, hypoxia, or pleuritic chest pain.

🦚 Regardless of the source, changes in behavior, especially agitation or clinginess in toddlers, must be assessed in context with other clinical symptoms.

Cough findings at 0800 → Acute Laryngotracheobronchitis

🦚 A barking, non-productive cough (described as "seal-like") is pathognomonic for croup.

🦚 This occurs due to inflammation and edema of the subglottic region of the airway, particularly affecting the larynx and trachea.

🦚 It often presents suddenly at night or early morning, as noted in the time-stamped clinical notes (0800 onset).

🦚 The absence of productive sputum, as expected in pneumonia, also supports croup as the diagnosis.

Stridor → Acute Laryngotracheobronchitis

🦚 Stridor is a high-pitched inspiratory sound resulting from turbulent airflow through a narrowed upper airway.

🦚 It is characteristic of croup, especially during agitation or crying, as it reflects laryngeal or tracheal narrowing.

🦚 It is not a typical finding in pneumonia, which primarily affects the alveoli and lower airways.

🦚 The presence of audible inspiratory stridor on exam reinforces the diagnosis of upper airway obstruction rather than lower lung infection.

Temperature → Both

🦚 The child had a low-grade fever (38.1–38.2°C / 100.6°F), which is common in both croup and pneumonia.

🦚 In viral laryngotracheobronchitis, low-grade fevers are expected, especially in early stages.

🦚 Pneumonia may present with low- or high-grade fevers depending on the etiologic agent (e.g., viral pneumonia tends to have milder fever compared to bacterial pneumonia).

🦚 Therefore, temperature alone cannot differentiate the two, making it a shared finding.

Answer 3

Correct Answers

Educate the child about proper perineal hygiene [ Anticipated ]
Administer sulfamethoxazole and trimethoprim [ Anticipated ]
Administer salicylic acid for pain and fever [ Contraindicated ]
Ensure the child receives a maximum of 1 ,200 mL/day of fluid [ Contraindicated ]
Advise child's guardian about the use of sunscreen [ Anticipated ]

Rationale :

Educate the child about proper perineal hygiene → ✅ Anticipated

🌊 Perineal hygiene education is a frontline preventive strategy for UTIs in children, particularly females.

🌊 Teaching the child to wipe front to back reduces bacterial transfer from the rectal area to the urethra.

🌊 Encouraging the child to void regularly and avoid holding urine also minimizes bacterial proliferation.

🌊 Hygiene education is essential in promoting self-care, preventing recurrence, and reducing caregiver burden.

Administer sulfamethoxazole and trimethoprim (TMP-SMX) → ✅ Anticipated

🌊 TMP-SMX is a broad-spectrum antibiotic commonly prescribed for UTIs caused by Escherichia coli, the most frequent uropathogen in children.

🌊 It works by inhibiting bacterial folic acid synthesis, disrupting DNA production.

🌊 The dosage of 8 mg TMP/kg/day PO aligns with pediatric dosing standards and should be administered consistently for the full course to avoid resistance.

🌊 Nurses must monitor for allergic reactions or gastrointestinal disturbances, which are common side effects.

Administer salicylic acid for pain and fever → ❌ Contraindicated

🌊 Salicylic acid is a topical keratolytic agent used for skin conditions (e.g., warts, acne), not systemic use.

🌊 It is not approved for pain or fever management, and its systemic absorption in children may cause toxicity.

🌊 Furthermore, medications in the salicylate class (e.g., aspirin) pose a risk of Reye syndrome in children recovering from viral illnesses.

🌊 Appropriate antipyretics such as acetaminophen or ibuprofen are preferred for pediatric fever management.

Ensure the child receives a maximum of 1,200 mL/day of fluid → ❌ Contraindicated

🌊 Restricting fluid intake contradicts UTI management principles, which focus on hydration to promote urinary flow and flushing of bacteria.

🌊 Adequate fluid intake helps dilute the urine, alleviating bladder irritation and promoting complete voiding.

🌊 Limiting fluid to 1,200 mL/day in a 7-year-old is inappropriate and may prolong infection or increase discomfort.

🌊 The goal is to encourage frequent urination, not fluid restriction.

Advise the child’s guardian about the use of sunscreen → ✅ Anticipated

🌊 Sulfamethoxazole/trimethoprim increases the risk of photosensitivity reactions, including sunburn and rashes.

🌊 Educating the caregiver about sun protection — such as broad-spectrum sunscreen, protective clothing, and limiting sun exposure — prevents photoallergic reactions.

🌊 This is especially important in active children who may spend extended time outdoors during therapy.

Correct Answers

Blank 1 Correct Option: Keep the child NPO
Blank 2 Correct Option: Prepare the child for flexible endoscopy

Rationale :

A. Keep the child NPO (Nothing by Mouth)

🛑 The most immediate nursing action in any suspected case of foreign body ingestion, particularly involving a button battery, is to maintain NPO status.

🛑 NPO is essential to reduce the risk of aspiration during sedation or procedural intervention, especially if endoscopic removal becomes necessary.

🛑 Button batteries can cause tissue necrosis, perforation, or hemorrhage within as little as 2 hours, making this a surgical emergency.

🛑 The presence of drooling, gagging, and wheezing indicates airway irritation and possibly esophageal impaction, further reinforcing the need to withhold oral intake immediately.

🛑 B. Prepare the child for flexible endoscopy

🛑 Once the child is stable and NPO, the next priority is to prepare for urgent endoscopic removal of the foreign object.

🛑 The X-ray confirms the presence of an object in the esophagus, which requires direct visualization and retrieval using a flexible endoscope under sedation.

🛑 Endoscopy is both diagnostic and therapeutic, allowing removal of the foreign body and assessment of tissue damage.

🛑 Delaying intervention could result in mucosal ulceration, perforation, or even fistula formation, especially with batteries, which leak alkaline substances.

🛑 The child’s vital signs (mild hypotension, increased respiratory rate) and respiratory symptoms (expiratory wheezing) suggest ongoing physiologic stress, making timely endoscopy imperative.

Answer 5

Correct Answers:

"You should cut and file your child's fingernails frequently"
"You should use a mild detergent for your child's laundry"
"Your child will experience occasional flare-ups of this condition."
"You can apply gloves to your child's hands!'
"You should apply emollients to your child's skin after bathing.

Rationale :

🎯 A. Cut and file your child's fingernails frequently

🌿 Short, smooth fingernails help prevent skin trauma from scratching, which can lead to excoriation, bleeding, and secondary bacterial infection (often by Staphylococcus aureus).

🌿 This is especially important in toddlers who may scratch during sleep, leading to further inflammation and worsening of lesions.

🌿 Filing nails instead of clipping can avoid sharp edges, which further protects the epidermal barrier in children with sensitive skin.

🎯 B. Use a mild detergent for laundry

🌿 Harsh detergents often contain fragrances and dyes, which can act as irritants or allergens, triggering eczema flare-ups.

🌿 Mild, fragrance-free detergents are less likely to leave residues on clothing that aggravate skin.

🌿 This is part of environmental control, especially important for children with atopic conditions, including allergic rhinitis, as in this case.

🎯 D. Your child will experience occasional flare-ups

🌿 Atopic dermatitis is a chronic relapsing condition, meaning that even with good management, periodic exacerbations are expected.

🌿 Triggers such as dry weather, allergens, infections, stress, or new skin products can cause these flare-ups.

🌿 Educating the caregiver that flare-ups are normal and manageable reduces anxiety and promotes long-term adherence to therapy.

🎯 F. You can apply gloves to your child’s hands

🌿 Wearing cotton mittens or gloves at night prevents involuntary scratching during sleep, which can worsen lesions and delay healing.

🌿 This intervention is especially useful in toddlers who may not understand verbal instructions to avoid scratching.

🌿 Gloves also help to preserve skin integrity and reduce the chance of infection and scarring.

🎯 G. Apply emollients after bathing

🌿 Emollients (moisturizers) are essential in atopic dermatitis to restore the skin barrier, which is often compromised and dry.

🌿 Applying them immediately after bathing helps trap moisture in the skin, a practice known as the “soak and seal” method.

🌿 Frequent application, especially after water exposure, is key to preventing trans-epidermal water loss (TEWL) and maintaining hydration.

Correct Answers:

"Your child should walk the bicycle through intersections."

Rationale :

🛞 Walking the bicycle across intersections is a safety guideline endorsed by the American Academy of Pediatrics (AAP) to reduce the risk of collisions with motor vehicles.

🛞 Intersections pose increased danger due to limited visibility, traffic flow, and unpredictable driver behavior.

🛞 Having the child dismount and walk the bicycle promotes greater control, caution, and pedestrian-level awareness.

🛞 It allows the child to obey traffic signals and navigate intersections safely, especially in high-traffic areas.

Answer 7

Correct Answers:

Reposition the client using a turning sheet.

Rationale :

🧷 A halo vest stabilizes the cervical spine following fracture or surgery, and the nurse must take extreme care during movement.

🧷 Repositioning the client should be done using a turning sheet, which allows for log rolling while maintaining cervical alignment.

🧷 This prevents any rotational or flexion movement that could displace the fracture or interfere with healing.

🧷 Turning sheets also help distribute weight and reduce skin breakdown risk, which is critical in immobilized clients.

Correct Answers:

Implement a 3 hr feeding schedule.

Rationale :

🍼 Infants with heart failure experience fatigue and dyspnea during feedings, making small, frequent feedings critical to avoid excessive exertion.

🍼 A 3-hour feeding schedule provides consistent caloric intake while minimizing stress on the cardiopulmonary system.

🍼 These infants are also at risk for failure to thrive, and scheduled feeds ensure adequate nutrition and monitoring of intake.

🍼 This practice also helps prevent volume overload, which can exacerbate fluid retention in heart failure.

Answer 10

Correct Answers:

Monitor oxygen saturation continuously_
Give oral hydroxyurea.
Instruct the parent to ensure the pneumococcal vaccine is current.
Administer folic acid as prescribed

Rationale :

🧬 A. Monitor oxygen saturation continuously

🧬 Hypoxia is a critical trigger for sickling of red blood cells in clients with sickle cell disease (SCD).

🧬 Continuous pulse oximetry allows for early detection of desaturation, enabling prompt oxygen therapy if saturation falls below acceptable levels.

🧬 The client’s cardiomegaly and low hemoglobin (6 g/dL) indicate a limited oxygen-carrying capacity, making monitoring vital to prevent further crises.

🧬 Continuous oxygen monitoring helps detect silent hypoxia, which can lead to acute chest syndrome, a life-threatening complication in SCD.

🧬 C. Give oral hydroxyurea

🧬 Hydroxyurea is a disease-modifying agent that increases fetal hemoglobin (HbF) production, which reduces sickling of red blood cells.

🧬 It helps reduce the frequency and severity of vaso-occlusive episodes by improving blood flow and oxygen delivery.

🧬 This medication is part of long-term preventive therapy, and maintaining the regimen during crisis periods helps prevent escalation.

🧬 It also decreases the need for blood transfusions and hospitalizations, improving quality of life.

🧬 E. Instruct the parent to ensure the pneumococcal vaccine is current

🧬 Children and adolescents with sickle cell disease are functionally asplenic due to repeated splenic infarctions, making them susceptible to encapsulated organisms such as Streptococcus pneumoniae.

🧬 The pneumococcal vaccine is essential for preventing life-threatening sepsis or meningitis.

🧬 Ensuring vaccine compliance aligns with CDC immunization guidelines for immunocompromised individuals.

🧬 This intervention is preventive and should be reinforced during hospitalization when education opportunities arise.

🧬 G. Administer folic acid as prescribed

🧬 Folic acid (vitamin B9) supports erythropoiesis—the formation of red blood cells in the bone marrow, which is highly active in clients with chronic hemolysis.

🧬 In sickle cell disease, the life span of RBCs is only 10–20 days, compared to 120 days in healthy individuals, leading to chronic anemia.

🧬 Supplementing folic acid promotes replacement of destroyed RBCs, improving oxygen delivery and reducing fatigue.

🧬 It is a standard part of maintenance therapy in sickle cell management.

🧬 F. Place the client on strict bed rest

🧬 During a vaso-occlusive crisis, movement can worsen pain, increase metabolic demand, and further impair perfusion to ischemic tissues.

🧬 Strict bed rest allows for joint and muscle relaxation, conserving energy and reducing oxygen needs.

🧬 This is especially important in this adolescent who presents with joint swelling, right knee inflammation, and pain rated 8/10.

🧬 Bed rest, combined with hydration, pain control, and oxygenation, forms the foundation of supportive care in VOC management.
