Question

A nurse is caring for a 2-year-old toddler in the pediatric unit who was admitted from the emergency department due to concerns about the child's breathing.

Answer 1

Correct Answers:

Oxygen saturation
Respiratory rate
Breath sounds in bilateral bases

Rationale :

✅ C. Oxygen saturation

🌬️ Improved oxygen saturation is one of the most direct and objective signs that a child with respiratory distress is responding well to treatment.

🌬️ On admission (0900), the child had an oxygen saturation of 88% on room air, which is below the expected normal range for children (typically ≥95%). This indicates moderate hypoxemia requiring supplemental oxygen.

🌬️ By 1200, oxygen saturation had improved to 94% on 2 L/min via nasal cannula, showing positive response to bronchodilators, steroids, and oxygen therapy.

🌬️ Although not yet at baseline, this improvement reflects better gas exchange and alveolar ventilation, especially with decreasing respiratory effort and improving clinical presentation.

🔹 Clinical Insight: In asthma, oxygen saturation trends guide decisions about oxygen weaning and overall stability. An improving trend toward 95% and above supports therapeutic efficacy.

✅ D. Respiratory rate

📉 A decrease in respiratory rate is a key indicator of reduced respiratory distress and improved oxygenation/ventilation status.

📉 Initially, the child had a respiratory rate of 40 breaths/min, which is above normal for a toddler (normal range: ~24–30 breaths/min). This tachypnea reflected air hunger, fatigue, and increased work of breathing.

📉 By 1200, the respiratory rate decreased to 32 breaths/min, showing the child is less tachypneic, suggesting decreased airway resistance and improved gas exchange.

📉 While still mildly elevated, the improvement is significant and correlates with better clinical stability and comfort.

🔹 Clinical Insight: Respiratory rate is one of the first signs to improve with effective bronchodilator and steroid therapy in asthma management. A declining rate reflects relief from bronchospasm and reduced fatigue.

✅ F. Breath sounds in bilateral bases

🫁 On admission, breath sounds were diminished in bilateral bases, which is typical in asthma due to air trapping, mucus plugging, and lower airway constriction.

🫁 By 1200, although still diminished, the presence of mild expiratory wheezing (and the absence of the previous "marked wheezing throughout inspiration and expiration") suggests airflow has improved, and bronchodilator therapy is helping open the smaller airways.

🫁 The ability to auscultate more distinct breath sounds—even if still reduced—means that air is moving better, and lower lobes are being ventilated, which was not as evident earlier.

🔹 Clinical Insight: In asthma, improving breath sounds in previously diminished areas can indicate clearing of mucus, resolution of atelectasis, or opening of airways, even when wheezing persists.

Answer 2

Correct Answers:

Obtain informed consent for surgery
Initiate IV antibiotics
Maintain NPO status
Obtain abdominal ultrasound

Rationale :

✅ B. Obtain informed consent for surgery

📝 The client’s worsening right lower quadrant (RLQ) pain, rebound tenderness, guarding, and a WBC count of 22,000/mm³, along with a CRP of 11.8 mg/dL, strongly suggest acute appendicitis, possibly requiring appendectomy.

📝 In pediatric clients, informed consent for surgery must be obtained from a parent or guardian—and assent from the child if developmentally appropriate.

📝 Early surgical consultation and preparation are critical to avoid perforation or peritonitis.

✅ D. Initiate IV antibiotics

💉 IV antibiotics are commonly ordered as preoperative management in suspected appendicitis to prevent or manage infection, especially if perforation is possible.

💉 Initiating broad-spectrum antibiotics helps reduce bacterial load and limit systemic spread, particularly if there's a delay in surgery.

💉 The provider may order ceftriaxone with metronidazole or other combinations as initial empiric therapy.

✅ E. Maintain NPO status

🚫 Clients with suspected appendicitis must remain NPO to prevent aspiration and prepare for possible emergency surgery.

🚫 The client is already nauseated and has vomited, reinforcing the need to withhold oral intake.

🚫 The nurse must also ensure that IV fluids are running at maintenance to support hydration.

✅ F. Obtain abdominal ultrasound

🖥️ Abdominal ultrasound is a first-line imaging test for suspected appendicitis in children due to its non-invasive nature and lack of radiation.

🖥️ It helps visualize the inflamed appendix, free fluid, or other causes of RLQ pain (e.g., ovarian torsion in females, mesenteric adenitis).

🖥️ If ultrasound is inconclusive, CT scan with contrast may be needed, but ultrasound is typically the initial step in pediatrics.

Answer 3

Correct Answers:

Reposition the client to a high Fowler's position.

Rationale :

🪑 The client is presenting with clinical signs of congestive heart failure (CHF), particularly left-sided heart failure, as evidenced by:

Tachypnea (RR 30/min)

Oxygen saturation of 90% (hypoxemia)

Wheezing throughout the lungs

Jugular vein distention, lower extremity edema, and cardiomegaly, indicating volume overload

Elevated BNP (1200 pg/mL) confirming ventricular strain

History of digoxin and furosemide administration, suggesting ongoing heart failure treatment

🪑 In this situation, the most appropriate and immediate nursing action is to reposition the client into High Fowler’s position, which uses gravity to reduce venous return, improve diaphragmatic expansion, and optimize lung ventilation.

🪑 High Fowler’s position will promote oxygenation and reduce pulmonary congestion, relieving dyspnea and work of breathing before other interventions take effect.

Answer 4

Correct Answers:

Oxygen saturation 88% on room air
Heart rate: 128/min
Passed three large, frothy, foul-smelling stools

Rationale :

✅ A. Oxygen saturation 88% on room air

🫁 An oxygen saturation of 88% is hypoxemic, even for a child with cystic fibrosis, whose baseline may be lower than that of healthy children.

🫁 This is a critical finding indicating impaired gas exchange, likely related to airway obstruction, mucus plugging, or progressive infection.

🫁 Given that the child was at 95% at 0700 and has dropped to 88% by 0900, this reflects a worsening respiratory status and requires provider notification for oxygen support or therapy adjustment.

🫁 In CF patients, early intervention helps prevent respiratory failure or need for advanced airway support.

✅ B. Heart rate: 128/min

💓 Tachycardia in a child with infection and respiratory distress is an important compensatory mechanism—but when it increases despite initial therapy (116 ➡ 128), it can indicate worsening oxygenation or early sepsis.

💓 This child also shows signs of hypotension (88/48) and persistent respiratory distress, making the elevated HR a red flag for cardiopulmonary compromise or systemic inflammatory response.

💓 Provider should be notified to evaluate for fluid support, oxygen therapy escalation, or antibiotic reassessment.

✅ E. Passed three large, frothy, foul-smelling stools

💩 This finding is significant in a child with cystic fibrosis, as it reflects malabsorption due to pancreatic insufficiency.

💩 Frothy, bulky, and foul-smelling stools are classic signs of steatorrhea—indicating poor digestion and possible need to adjust pancreatic enzyme therapy or increase nutritional support.

💩 Even if the child has no current abdominal pain, this pattern suggests poor nutrient absorption, which over time contributes to failure to thrive or weight loss in CF.

💩 The provider may consider dietary modification or reassess enzyme dosing.

Answer 5

Correct Answers:

Oxygen saturation
Breath sounds in bilateral bases
Respiratory rate
Heart rate

Rationale :

✅ C. Oxygen saturation

🫁 Oxygen saturation is one of the most objective indicators of respiratory improvement. Initially, the child had an SpO₂ of 89% on room air, which indicates moderate hypoxemia.

🫁 After initiation of 2 L/min nasal cannula oxygen and nebulized albuterol, an increase in SpO₂ (ideally to ≥94%) would reflect improved alveolar oxygen exchange.

🫁 Improvement in oxygenation shows that bronchodilation, oxygen therapy, and reduced airway resistance are helping the child breathe more effectively.

✅ D. Breath sounds in bilateral bases

🩺 Initially, breath sounds were described as diminished with wheezing, a sign of air trapping and poor ventilation.

🩺 With effective bronchodilator treatment (albuterol), we expect airflow to improve, resulting in more audible breath sounds, especially in the lower lung fields.

🩺 Improved breath sounds suggest that airways are opening, mucus clearance is improving, and lung inflation is more effective.

✅ E. Respiratory rate

🌬️ The toddler’s initial respiratory rate was 42/min, which is significantly elevated (normal for age: ~22–30/min).

🌬️ A decreasing respiratory rate is one of the earliest signs that work of breathing is reducing.

🌬️ This indicates that the child is less tachypneic, has less air hunger, and is not as fatigued from labored breathing.

🌬️ Normalizing respiratory rate suggests clinical improvement and treatment effectiveness.

✅ F. Heart rate

💓 The child’s heart rate was initially 148/min, which is elevated for a toddler, especially in the context of fever, hypoxia, and distress.

💓 With treatment (oxygen, antipyretics, albuterol), a decline in heart rate indicates reduced stress response, improved oxygen delivery, and lower metabolic demand.

💓 While HR may still be slightly elevated due to fever or crying, a downward trend is an important marker of stabilization.

Answer 6

Correct Answers:

Do not palpate abdomen.

Rationale :

🛑 Wilms tumor, or nephroblastoma, is a malignant renal tumor that is encapsulated and highly vascular.

🛑Palpating the abdomen can rupture the tumor capsule, leading to cancer cell dissemination into the peritoneum or bloodstream.

🛑For this reason, the nurse should place a clear warning sign that reads "Do not palpate abdomen" at the child’s bedside.

🛑 All caregivers must be informed of this critical precaution to prevent iatrogenic harm.

Answer 7

Correct Answers:

Place him in knee-chest position.

Rationale :

🧍 During a "Tet spell" in Tetralogy of Fallot, the child experiences sudden hypoxia and cyanosis due to increased right-to-left shunting.

🧍 Placing the child in the knee-chest position increases systemic vascular resistance, which reduces the shunt and redirects more blood to the lungs.

🧍 This position also calms the child, lowers oxygen demand, and improves pulmonary perfusion.

🧍 It is a critical first response during these episodes.

Answer 8

Correct Answers:

Severe dehydration.

Rationale :

💧 The infant has lost 0.7 kg (700 grams), which equals about 14% body weight loss in just 24 hours—a red flag for severe dehydration.

💧 In infants, a loss of over 10% of body weight from fluid is considered life-threatening and requires urgent rehydration, typically with IV fluids, lab monitoring, and electrolyte replacement.

💧This is far beyond a mild deficit or risk—it’s an active clinical emergency.

Answer 9

Correct Answers:

Genetics.

Rationale :

🧬 Genetics is the primary, unchangeable influence on a child’s physical and cognitive development. It determines height, growth patterns, developmental timing, and predisposition to illnesses.

🧬While environment, nutrition, and social factors modify outcomes, genetic blueprint sets the foundational potential for each child.

🧬Nurses can educate families on supporting a child’s development, but genetics is not subject to change through external factors.

Answer 10

Correct Answers:

Measure head circumference every shift.

Rationale :

📏 Head circumference is routinely used for infants under 2 years of age to monitor for increased intracranial pressure due to their open fontanels and skull sutures.

📏In a 6-year-old, the skull is already fused, making this assessment inappropriate and clinically unnecessary.

📏More appropriate interventions include droplet precautions, seizure precautions, and semi-Fowler’s positioning to promote comfort and decrease intracranial pressure.
