176Question
A nurse is providing discharge education to a client who has experienced a pregnancy loss. Which statement by the client indicates the need for further teaching?
- "I should try to move on quickly and not dwell on the loss."
- "I may experience hormonal changes that affect my emotions."
- "I should watch for signs of infection, like fever or foul-smelling discharge."
- "I will need emotional support, and it’s okay to grieve in my own way."
Show the answer and explanation
Answer: A. "I should try to move on quickly and not dwell on the loss."
Topic: Pregnancy Loss Discharge Education
Grief after pregnancy loss is a unique, non-linear process with no set timeline. Encouraging a client to suppress emotions or 'move on quickly' is maladaptive and indicates a need for further education on healthy coping strategies.
Why the others are wrong
- B – Recognizing that postpartum hormonal shifts impact emotional well-being is accurate and requires no intervention.
- C – Watching for fever and foul-smelling discharge shows correct understanding of post-loss infection risks.
- D – Acknowledging the need for individualized grief support indicates a healthy understanding of emotional recovery.
Remember: Grief has no timeline; suppressive coping hinders healing.

In Kohlberg’s post-conventional stage, moral reasoning is based on:
- Fear of punishment and reward-seeking
- The expectations of authority figures
- Maintaining interpersonal relationships
- Universal ethical principles and abstract reasoning
Show the answer and explanation
Answer: D. Universal ethical principles and abstract reasoning
Topic: Kohlberg Moral Development
In Kohlberg’s post‑conventional stage, individuals base moral decisions on self‑chosen ethical principles that transcend laws, using abstract, principled reasoning. They evaluate right and wrong by universal concepts such as justice and human rights, rather than external rewards or authority.
Why the others are wrong
- A – It reflects pre‑conventional reasoning focused on avoiding punishment and gaining rewards.
- B – It represents conventional stage, where behavior follows authority and societal rules.
- C – It describes conventional reasoning, which centers on social approval and relationships.
Remember: Post‑conventional: universal principles, not rules or rewards.

Which of the following is a characteristic symptom of severe croup?
- Diarrhea
- Stridor
- Sneezing
- Runny nose
Show the answer and explanation
Answer: B. Stridor
Topic: Severe Croup Symptoms
Croup is an upper airway infection characterized by swelling of the larynx and trachea. Stridor, a high-pitched inspiratory sound, is a hallmark sign of severe croup, indicating significant airway obstruction requiring immediate medical evaluation.
Why the others are wrong
- A – Diarrhea is a gastrointestinal symptom and is not associated with croup.
- C – Sneezing is a mild upper respiratory symptom, not indicative of severe croup or airway obstruction.
- D – A runny nose is a common prodromal symptom of mild croup, not severe airway compromise.
Remember: Croup causes a barking cough and stridor as the airway narrows.

182Question
An eight-year-old child presents to the emergency department with suspected epiglottitis. Which of the following is the priority to include in the client’s plan of care?
- Ensure the client has a patent airway.
- Send the client to radiology for a lateral neck X-ray.
- Ensure the client has IV access.
- Explain the disease to the client’s caregivers.
Show the answer and explanation
Answer: A. Ensure the client has a patent airway.
Topic: Epiglottitis Airway Management
Epiglottitis is a life-threatening emergency that can cause rapid, complete airway obstruction. Maintaining a patent airway is the absolute priority, and any invasive procedures that could agitate the child and trigger laryngospasm must be delayed.
Why the others are wrong
- B – Transporting the child to radiology is unsafe; imaging must be done portably at the bedside.
- C – IV insertion can agitate the child, potentially triggering complete airway obstruction from laryngospasm.
- D – Caregiver education is important but secondary to stabilizing the child's life-threatening airway compromise.
Remember: Epiglottitis: Airway first, keep them calm.

183Question
A nurse is counseling a parent about their preschool-aged child who often asks, “Why?” and wants to help with household tasks. The nurse explains that encouraging the child’s curiosity and independence supports which stage of Erikson’s psychosocial development?
- Trust vs. mistrust
- Autonomy vs. shame and doubt
- Identity vs. role confusion
- Initiative vs. guilt
Show the answer and explanation
Answer: D. Initiative vs. guilt
Topic: Erikson Initiative Stage
At ages 3‑5, children naturally explore, ask “why,” and want to help; Erikson’s Initiative vs. Guilt stage describes this drive toward purposeful activity, so encouraging curiosity and independence fosters a healthy sense of initiative.
Why the others are wrong
- A – Infancy stage about caregiver reliability, not curiosity.
- B – Toddler stage focused on self‑control, not purposeful initiative.
- C – Adolescent stage dealing with identity, unrelated to preschool behavior.
Remember: Preschool curiosity signals Erikson’s Initiative stage.

- Initiate antibiotic therapy.
- Administer antiviral medications.
- Administer saline nasal spray.
- Encourage physical activity.
Show the answer and explanation
Answer: C. Administer saline nasal spray.
Topic: Pediatric URI Management
Pediatric upper respiratory infections are primarily viral, requiring supportive care rather than medications. Administering saline nasal sprays safely thins mucus and relieves congestion, promoting comfort and easier breathing in young children.
Why the others are wrong
- A – Antibiotics are ineffective against viral pathogens and promote bacterial resistance.
- B – Antivirals are not indicated for routine, uncomplicated pediatric viral upper respiratory infections.
- D – Rest is encouraged over physical activity to conserve energy and promote healing.
Remember: For pediatric URIs, saline spray clears the way.

- Administering antibiotics to prevent infection
- Limiting fluids to reduce the risk of aspiration
Show the answer and explanation
Answer: A. Providing humidified oxygen and monitoring respiratory status
Topic: Bronchiolitis Nursing Care
Bronchiolitis is a viral lower respiratory tract infection primarily managed with supportive care. Maintaining adequate oxygenation via humidified oxygen and closely monitoring for respiratory distress are the highest priorities to ensure airway patency and gas exchange.
Why the others are wrong
- B – Rest is encouraged to minimize oxygen consumption; physical activity can worsen respiratory distress.
- C – Antibiotics are ineffective against viral infections like bronchiolitis and are not routinely indicated.
- D – Hydration is essential to thin secretions; fluids should be encouraged, not limited.
Remember: Bronchiolitis is viral: focus on oxygen, hydration, and rest.

186Question
A 4-year-old child with cystic fibrosis is admitted for a pulmonary exacerbation. The parent asks why the child must take pancrelipase capsules with every meal and snack. Which response by the nurse is best?
- These enzymes prevent thick mucus buildup in the child's small airways.
- Pancrelipase replaces missing enzymes so the child can digest fats, proteins, and carbohydrates.
- This medication stimulates the pancreas to produce insulin, preventing cystic fibrosis-related diabetes.
- The capsules coat the stomach lining to prevent irritation from high-calorie nutritional supplements.
Show the answer and explanation
Answer: B. Pancrelipase replaces missing enzymes so the child can digest fats, proteins, and carbohydrates.
Topic: Pancrelipase mechanism
Pancrelipase contains lipase, protease, and amylase, which replace deficient exocrine pancreatic enzymes in children with cystic fibrosis. Without these enzymes, malabsorption of fats, proteins, and carbohydrates leads to steatorrhea, poor weight gain, and nutritional deficiencies.
Why the others are wrong
- A – Bronchodilators and airway clearance techniques address mucus buildup in the airways, not pancreatic enzymes.
- C – Pancrelipase has no effect on insulin production or pancreatic endocrine function.
- D – Pancrelipase works in the lumen of the gastrointestinal tract to digest food, not as a mucosal protectant.

187Question
An adolescent client with type 1 diabetes mellitus is admitted in diabetic ketoacidosis (DKA). The client's blood glucose is 420 mg/dL, and regular insulin is being infused continuously via intravenous pump. Which laboratory value requires the nurse's immediate attention?
- Serum potassium of 3.1 mEq/L
- Serum bicarbonate of 14 mEq/L
- Blood urea nitrogen of 18 mg/dL
- Serum sodium of 135 mEq/L
Show the answer and explanation
Answer: A. Serum potassium of 3.1 mEq/L
Topic: DKA management complications
Insulin therapy drives potassium back into the intracellular space, which can precipitate severe hypokalemia during the treatment of DKA. A serum potassium of 3.1 mEq/L is below the normal range (3.5-5.0 mEq/L) and must be corrected with potassium supplementation before continuing insulin infusion to prevent lethal cardiac dysrhythmias.
Why the others are wrong
- B – A serum bicarbonate of 14 mEq/L indicates ongoing metabolic acidosis associated with DKA, which improves gradually with fluid and insulin therapy, but it is not immediately life-threatening like severe electrolyte shifts.
- C – A blood urea nitrogen of 18 mg/dL is within the normal reference range for adolescents.
- D – A serum sodium of 135 mEq/L is within or very close to the normal reference range, though corrected sodium must be monitored for osmolar shifts.

188Question
A 4-year-old child with acute post-streptococcal glomerulonephritis (APSGN) is admitted to the pediatric unit. Which nursing intervention is most critical to include in the child's plan of care?
- Encourage a high-protein, high-sodium diet to compensate for urinary losses.
- Monitor daily weights and blood pressure every 4 hours.
- Administer prescribed loop diuretics and potassium supplements.
- Maintain strict bed rest throughout the acute phase of the illness.
Show the answer and explanation
Answer: B. Monitor daily weights and blood pressure every 4 hours.
Topic: Acute post-streptococcal glomerulonephritis monitoring
Hypertension and fluid overload are hallmark complications of acute post-streptococcal glomerulonephritis due to decreased glomerular filtration. Monitoring daily weights and frequent blood pressure checks are essential to assess fluid balance and detect hypertensive emergencies early.
Why the others are wrong
- A – Sodium and fluid intake are typically restricted during the acute phase of APSGN to manage edema and hypertension, not increased.
- C – Potassium supplements are contraindicated because oliguria and decreased GFR place the child at high risk for hyperkalemia.
- D – Strict bed rest is not required unless the child has severe hypertension; early mobilization is generally permitted as tolerated, making vitals monitoring a higher priority.

189Question
A nurse is providing discharge instructions to the parents of a school-age child diagnosed with newly managed type 1 diabetes mellitus. Which statement by a parent indicates a correct understanding of sick-day management?
- "We will stop insulin administration if our child refuses to eat due to nausea and vomiting."
- "We will check blood glucose levels every 4 hours and test urine for ketones whenever blood glucose is above 240 mg/dL."
- "We will encourage our child to drink large amounts of sugar-sweetened beverages to maintain caloric intake while sick.
"
- "We will restrict all physical activity completely until the acute illness has fully resolved."
Show the answer and explanation
Answer: B. "We will check blood glucose levels every 4 hours and test urine for ketones whenever blood glucose is above 240 mg/dL."
Topic: Type 1 diabetes sick-day management
During illness, counter-regulatory stress hormones increase blood glucose levels, and ketogenesis can occur rapidly in children with type 1 diabetes. Checking blood glucose frequently (every 3 to 4 hours) and testing urine for ketones when glucose exceeds 240 mg/dL are core components of safe sick-day management.
Why the others are wrong
- A – Insulin should never be stopped during illness; omitting insulin is a primary precipitating factor for diabetic ketoacidosis, even when oral intake is poor.
- C – Sugar-sweetened beverages can cause severe hyperglycemia during illness; sugar-free or electrolyte fluids should be used if blood glucose is elevated.
- D – Complete restriction of physical activity is unnecessary unless the child is ketotic or too ill, though heavy exercise should be avoided during acute illness.

190Question
The nurse is admitting a 4-year-old child with nephrotic syndrome who has generalized edema and a 2-kg weight gain over the past week. Which prescribed intervention should the nurse anticipate as the primary medical therapy to reduce proteinuria and edema?
- Intravenous 25% albumin infusion
- Oral corticosteroid therapy (prednisone)
- Low-sodium, fluid-restricted diet
- Prophylactic broad-spectrum antibiotics
Show the answer and explanation
Answer: B. Oral corticosteroid therapy (prednisone)
Topic: Nephrotic syndrome initial medical therapy
Corticosteroids, specifically oral prednisone, are the first-line medical therapy for minimal change nephrotic syndrome in children, aimed at inducing remission by reducing glomerular permeability to protein. Once remission is achieved, edema and proteinuria typically resolve.
Why the others are wrong
- A – Albumin infusions are used temporarily for severe, symptomatic edema or hypovolemia, but they do not treat the underlying disease process causing proteinuria.
- C – Dietary sodium restriction and sometimes fluid management help control edema symptoms, but they do not treat the underlying glomerular permeability.
- D – Antibiotics are only used if a specific bacterial infection (such as spontaneous bacterial peritonitis) is diagnosed, not as routine primary prophylaxis.

191Question
The nurse is providing discharge teaching to the parents of a 6-month-old infant following surgical correction of congenital hyperinsulinism. Which statement by the parents indicates a correct understanding of home blood glucose monitoring and hypoglycemia recognition?
- "We will stop checking blood sugars once our baby starts eating solid foods regularly."
- "If our baby becomes unusually lethargic or jittery, we should check a blood glucose immediately."
- "We only need to test blood glucose if our baby has a fever or vomits."
- "Low blood sugar in infants always causes crying and irritability rather than sleepiness."
Show the answer and explanation
Answer: B. "If our baby becomes unusually lethargic or jittery, we should check a blood glucose immediately."
Topic: Congenital hyperinsulinism home care and hypoglycemia
Congenital hyperinsulinism causes persistent hypoglycemia due to unregulated insulin secretion. Parents must recognize symptoms of hypoglycemia, which in infants include lethargy, jitteriness, poor feeding, hypothermia, and seizures, and know when to check blood glucose.
Why the others are wrong
- A – Solid foods do not resolve congenital hyperinsulinism; ongoing glucose monitoring and medical management are required.
- C – Hypoglycemia can occur at any time due to the underlying defect, not just during periods of acute illness.
- D – Infants with hypoglycemia often present with lethargy, poor tone, and hypotonia rather than excessive crying.

193Question
The pediatric nurse is evaluating an 8-year-old child admitted with an acute asthma exacerbation. Which assessment finding indicates that the child is experiencing a life-threatening deterioration requiring immediate emergency intervention?
- Expiratory wheezing audible without a stethoscope
- A respiratory rate of 34 breaths/min with mild intercostal retractions
- Diminished breath sounds with a silent chest and severe lethargy
- A pulse oximetry reading of 91% on room air
Show the answer and explanation
Answer: C. Diminished breath sounds with a silent chest and severe lethargy
Topic: Severe asthma exacerbation assessment
A silent chest (absence of wheezing due to severely diminished airflow) combined with lethargy or altered mental status indicates impending respiratory arrest and is a medical emergency.
Why the others are wrong
- A – Expiratory wheezing indicates airway narrowing and bronchospasm, which is expected in an asthma exacerbation, but hearing it without a stethoscope does not automatically mean impending arrest.
- B – Tachypnea and mild intercostal retractions reflect moderate respiratory distress requiring bronchodilators and close monitoring, but not immediate arrest.
- D – An oxygen saturation of 91% indicates hypoxemia requiring supplemental oxygen, but it is not as immediately life-threatening as a silent chest and lethargy.

- Inability to swallow secretions
- Primary involuntary rhythmic tremors
- Oral mucosal burns and ulcerations
- Severe retrosternal or abdominal pain
Show the answers and explanation
Answers: A, B, D and E.
- A – Drooling and excessive salivation
- B – Inability to swallow secretions
- D – Oral mucosal burns and ulcerations
- E – Severe retrosternal or abdominal pain
Topic: Caustic Ingestion Manifestations
Ingestion of caustic substances (acids or alkalis found in household cleaners) causes immediate chemical burns to the upper gastrointestinal tract. Clinical signs include drooling, inability to swallow (due to severe pain and edema), visible oral mucosal burns and ulcerations, and severe retrosternal or abdominal pain. Tremors are not a primary sign of caustic ingestion.
Why the others are wrong
- C – Primary involuntary rhythmic tremors are associated with neurotoxins or specific drug overdoses, not acute caustic chemical ingestion.

195Question
An infant with developmental dysplasia of the hip (DDH) is being discharged home wearing a Pavlik harness. Which discharge instruction is most important for the nurse to provide to the parents?
- Apply lotion and powder under the harness straps daily to prevent skin breakdown.
- Adjust the chest strap twice daily to accommodate the infant's growth and breathing.
- Check skin folds under the straps daily and dress the infant in a shirt and knee socks under the harness.
- Remove the harness for 1 hour twice a day to allow for tummy time and active leg stretching.
Show the answer and explanation
Answer: C. Check skin folds under the straps daily and dress the infant in a shirt and knee socks under the harness.
Topic: Pavlik Harness Home Care
Skin integrity is a major priority for an infant in a Pavlik harness. Placing soft layers like a undershirt and knee socks under the harness prevents direct friction against the skin, and parents must check skin folds daily for redness or irritation. Lotions and powders trap moisture and increase the risk of skin breakdown.
Why the others are wrong
- A – Lotions and powders trap moisture against the skin under the straps, increasing the risk of friction and skin breakdown.
- B – Parents must never adjust the straps of a Pavlik harness; all adjustments must be performed by the orthopedist to maintain proper hip reduction.
- D – The Pavlik harness is worn continuously (typically 23 to 24 hours daily); removal is only permitted if explicitly ordered by the physician.

A 4-year-old child with acute lymphocytic leukemia (ALL) is brought to the emergency department by their parents with a 39.2°C (102.5°F) temperature, shaking chills, and lethargy. Which nursing action is the absolute priority?
- Administer the prescribed weight-based antipyretic.
- Obtain ordered blood cultures from two sites and start broad-spectrum IV antibiotics.
- Place the child in strict airborne isolation precautions.
- Perform a comprehensive head-to-toe physical assessment.
Show the answer and explanation
Answer: B. Obtain ordered blood cultures from two sites and start broad-spectrum IV antibiotics.
Topic: Neutropenic Fever Management
Neutropenic fever is an oncologic emergency; obtaining blood cultures and immediately initiating empiric broad-spectrum antibiotics within 60 minutes prevents rapid septic shock and death.
Why the others are wrong
- A – Administering an antipyretic should follow blood cultures, but masking the fever without treating the underlying infection with prompt antibiotics places the child at severe risk for septic shock.
- C – A neutropenic client requires protective (reverse) isolation, not airborne precautions, unless a specific airborne pathogen is identified.
- D – While assessment is important, delaying life-saving antibiotic therapy to perform a comprehensive head-to-toe physical examination compromises client safety in an emergency.

197Question
A 4-year-old child with acute lymphocytic leukemia (ALL) is admitted to the pediatric unit for chemotherapy. Which nursing intervention is the highest priority to prevent life-threatening complications during the induction phase?
- Encourage a diet rich in fresh citrus fruits and raw vegetables.
- Place the child in a private room and enforce strict hand hygiene.
- Administer scheduled rectal temperature checks every 4 hours.
- Encourage high-impact indoor physical play to prevent joint stiffness.
Show the answer and explanation
Answer: B. Place the child in a private room and enforce strict hand hygiene.
Topic: Leukemia chemotherapy precautions
Children receiving induction chemotherapy for ALL experience severe bone marrow suppression, leading to neutropenia and high vulnerability to overwhelming infection. Placing the child in a private room and enforcing strict hand hygiene minimizes exposure to pathogens.
Why the others are wrong
- A – Fresh raw fruits and vegetables are restricted in neutropenic diets due to the risk of bacterial and fungal contamination.
- C – Rectal temperatures and rectal medications are strictly contraindicated in children with leukemia due to the high risk of mucosal tears, bleeding, and introduction of bacteria leading to sepsis.
- D – Children with leukemia frequently have thrombocytopenia, making high-impact play dangerous due to the high risk of bleeding and bruising.

- “We will purchase a soft-bristled toothbrush for our child's daily hygiene.”
- “Contact sports and rough playground climbing are off-limits for now.”
- “We can give ibuprofen instead of acetaminophen if our child complains of mild headaches.”
- “We need to watch closely for any sudden appearance of petechiae or unusual bruising.”
- “If our child experiences a minor nosebleed, we should immediately pack the nares tightly with cotton.”
Show the answers and explanation
Answers: A, B and D.
- A – “We will purchase a soft-bristled toothbrush for our child's daily hygiene.”
- B – “Contact sports and rough playground climbing are off-limits for now.”
- D – “We need to watch closely for any sudden appearance of petechiae or unusual bruising.”
Topic: Idiopathic thrombocytopenic purpura home care
ITP is characterized by destruction of platelets, increasing bleeding risks. Soft toothbrushes, avoiding contact sports, and monitoring for petechiae are key safety measures. NSAIDs and tight nasal packing are contraindicated.
Why the others are wrong
- C – Ibuprofen and other NSAIDs inhibit platelet aggregation and are strictly avoided in bleeding disorders like ITP; acetaminophen is used for pain.
- E – Tight nasal packing is inappropriate for epistaxis; standard management involves sitting upright, leaning forward, and applying continuous direct pressure to the soft lower portion of the nose for 10-15 minutes.

An 8-year-old child with type 1 diabetes mellitus is brought to the emergency department lethargic, with deep, rapid respirations and a fruity odor to their breath. Laboratory results reveal a blood glucose of 520 mg/dL and a serum pH of 7.18. Which prescribed action should the nurse implement first?
- Initiate an intravenous infusion of regular insulin at 0.1 units/kg/hour.
- Administer a bolus of 0.9% sodium chloride intravenously.
- Administer sodium bicarbonate intravenous push over 10 minutes.
- Obtain a baseline serum potassium level and prepare for replacement.
Show the answer and explanation
Answer: B. Administer a bolus of 0.9% sodium chloride intravenously.
Topic: Diabetic ketoacidosis initial management
In pediatric diabetic ketoacidosis (DKA), restoring intravascular volume with an isotonic saline bolus is the absolute first priority to improve renal perfusion and lower blood glucose via dilution and clearance before starting insulin infusions.
Why the others are wrong
- A – Although insulin is necessary to stop ketogenesis, starting it before initiating fluid resuscitation risks severe cardiovascular collapse as water shifts out of the intravascular space.
- C – Sodium bicarbonate is not routinely recommended for DKA because rapid correction of acidosis can lead to paradoxical cerebrospinal fluid acidosis and cerebral edema.
- D – Monitoring and replacing potassium is critical during DKA management, but fluid resuscitation must be established first.

200Question
An 8-year-old child with cystic fibrosis is admitted for a pulmonary exacerbation. The nurse reviews the morning laboratory results and notes a serum sodium level of 128 mEq/L (128 mmol/L), serum potassium of 4.0 mEq/L, and chloride of 90 mEq/L. The child reports lethargy and muscle cramps. Which physiological mechanism best explains this electrolyte disturbance?
- Excessive renal potassium wasting secondary to chronic loop diuretic use
- Inadequate dietary salt intake coupled with excessive dermal sodium loss in sweat
- Water intoxication caused by impaired renal free-water clearance from antidiuretic hormone suppression
- Intracellular shifts of sodium resulting from acute metabolic alkalosis
Show the answer and explanation
Answer: B. Inadequate dietary salt intake coupled with excessive dermal sodium loss in sweat
Topic: Cystic Fibrosis Hyponatremia
Children with cystic fibrosis have dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR) proteins, which lead to extremely high concentrations of sodium and chloride in sweat. Combined with restricted dietary salt and high ambient temperatures or fever, this causes chronic depletion and acute hypochloremic hyponatremia.
Why the others are wrong
- A – Loop diuretics waste potassium and chloride primarily, and are rarely the root cause of primary hyponatremia in standard cystic fibrosis exacerbations.
- C – While water restriction or abnormal water handling can occur, the hallmark of CF-related hyponatremia is actual salt depletion through sweat and inadequate replacement, rather than ADH suppression.
- D – Metabolic alkalosis can occur in CF due to chronic chloride loss, but sodium shifts do not account for total body sodium depletion caused by high sweat electrolyte losses.
